Tags Share this article 6/22/20 Published Avishai Wool, CTO and co-founder of AlgoSec, looks at how organizations can implement and manage SDN-enabled micro-segmentation strategies Micro-segmentation is regarded as one of the most effective methods to reduce an organization’s attack surface, and a lack of it has often been cited as a contributing factor in some of the largest data breaches and ransomware attacks. One of the key reasons why enterprises have been slow to embrace it is because it can be complex and costly to implement – especially in traditional on-premise networks and data centers. In these, creating internal zones usually means installing extra firewalls, changing routing, and even adding cabling to police the traffic flows between zones, and having to manage the additional filtering policies manually. However, as many organizations are moving to virtualized data centers using Software-Defined Networking (SDN), some of these cost and complexity barriers are lifted. In SDN-based data centers the networking fabric has built-in filtering capabilities, making internal network segmentation much more accessible without having to add new hardware. SDN’s flexibility enables advanced, granular zoning: In principle, data center networks can be divided into hundreds, or even thousands, of microsegments. This offers levels of security that would previously have been impossible – or at least prohibitively expensive – to implement in traditional data centers. However, capitalizing on the potential of micro-segmentation in virtualized data centers does not eliminate all the challenges. It still requires the organization to deploy a filtering policy that the micro-segmented fabric will enforce, and writing this a policy is the first, and largest, hurdle that must be cleared. The requirements from a micro-segmentation policy A correct micro-segmentation filtering policy has three high-level requirements: It allows all business traffic – The last thing you want is to write a micro-segmented policy and have it block necessary business communication, causing applications to stop functioning. It allows nothing else – By default, all other traffic should be denied. It is future-proof – ‘More of the same’ changes in the network environment shouldn’t break rules. If you write your policies too narrowly, when something in the network changes, such as a new server or application, something will stop working. Write with scalability in mind. A micro-segmentation blueprint Now that you know what you are aiming for, how can you actually achieve it? First of all, your organization needs to know what your traffic flows are – what is the traffic that should be allowed. To get this information, you can perform a ‘discovery’ process. Only once you have this information, can you then establish where to place the borders between the microsegments in the data center and how to devise and manage the security policies for each of the segments in their network environment. I welcome you to download AlgoSec’s new eBook , where we explain in detail how to implement and manage micro-segmentation. AlgoSec Enables Micro-segmentation The AlgoSec Security Management Suite (ASMS) employs the power of automation to make it easy to define and enforce your micro-segmentation strategy inside the data center, ensure that it does not block critical business services, and meet compliance requirements. AlgoSec supports micro-segmentation by: Providing application discovery based on netflow information Identifying unprotected network flows that do not cross any firewall and are not filtered for an application Automatically identifying changes that will violate the micro-segmentation strategy Automatically implementing network security changes Automatically validating changes The bottom line is that implementing an effective network micro-segmentation strategy is now possible. It requires careful planning and implementation, but when carried out following a proper blueprint and with the automation capabilities of the AlgoSec Security Management Suite, it provides you with stronger security without sacrificing any business agility.

Full Cloud Security Checklist 1. Understand Cloud Security Risks 1a. Identify Sensitive Information First, identify all your sensitive information. This data could range from customer information to patents, designs, and trade secrets. 1b. Understand Data Access and Sharing Use access control measures, like role-based access control (RBAC), to manage data access. You should also understand and control how data is shared. One idea is to use data loss prevention (DLP) tools to prevent unauthorized data transfers. 1c. Explore Shadow IT Shadow IT refers to using IT tools and services without your company’s approval. While these tools can be more productive or convenient, they can pose security risks. 2. Establish a Shared Responsibility Agreement with Your Cloud Service Provider (CSP) Understanding the shared responsibility model in cloud security is essential. There are various models – IaaS, PaaS, or SaaS. Common CSPs include Microsoft Azure and AWS. 2a. Establish Visibility and Control It’s important to establish strong visibility into your operations and endpoints. This includes understanding user activities, resource usage, and security events. Using security tools gives you a centralized view of your secure cloud environment. You can even enable real-time monitoring and prompt responses to suspicious activities. Cloud Access Security Brokers (CASBs) or cloud-native security tools can be useful here. 2b. Ensure Compliance Compliance with relevant laws and regulations is fundamental. This could range from data protection laws to industry-specific regulations. 2c. Incident Management Despite your best efforts, security incidents can still occur. Having an incident response plan is a key element in managing the impact of any security events. This plan should tell team members how to respond to an incident. 3. Establish Cloud Data Protection Policies Create clear policies around data protection in the cloud . These should cover areas such as data classification, encryption, and access control. These policies should align with your organizational objectives and comply with relevant regulations. 3a. Data Classification You should categorize data based on its sensitivity and potential impact if breached. Typical classifications include public, internal, confidential, and restricted data. 3b. Data Encryption Encryption protects your data in the cloud and on-premises. It involves converting your data so it can only be read by those who possess the decryption key. Your policy should mandate the use of strong encryption for sensitive data. 3c. Access Control Each user should only have the access necessary to perform their job function and no more. Policies should include password policies and changes of workloads. 4. Set Identity and Access Management Rules 4a. User Identity Management Identity and Access Management tools ensure only the right people access your data. Using IAM rules is critical to controlling who has access to your cloud resources. These rules should be regularly updated. 4b. 2-Factor and Multi-Factor Authentication Two-factor authentication (2FA) and multi-factor authentication (MFA) are useful tools. You reduce the risk by implementing 2FA or MFA, even if a password is compromised. 5. Set Data Sharing Restrictions 5a. Define Data Sharing Policies Define clear data-sharing permissions. These policies should align with the principles of least privilege and need-to-know basis. 5b. Implement Data Loss Prevention (DLP) Measures Data Loss Prevention (DLP) tools can help enforce data-sharing policies. These tools monitor and control data movements in your cloud environment. 5c. Audit and Review Data Sharing Activities Regularly review and audit your data-sharing activities to ensure compliance. Audits help identify any inappropriate data sharing and provide insights for improvement. 6. Encrypt Sensitive Data Data encryption plays a pivotal role in safeguarding your sensitive information. It involves converting your data into a coded form that can only be read after it’s been decrypted. 6a. Protect Data at Rest This involves transforming data into a scrambled form while it’s in storage. It ensures that even if your storage is compromised, the data remains unintelligible. 6b. Data Encryption in Transit This ensures that your sensitive data remains secure while it’s being moved. This could be across the internet, over a network, or between components in a system. 6c. Key Management Managing your encryption keys is just as important as encrypting the data itself. Keys should be stored securely and rotated regularly. Additionally, consider using hardware security modules (HSMs) for key storage. 6d. Choose Strong Encryption Algorithms The strength of your encryption depends significantly on the algorithms you use. Choose well-established encryption algorithms. Advanced Encryption Standard (AES) or RSA are solid algorithms. 7. Employ a Comprehensive Data Backup and Recovery Plan 7a. Establish a Regular Backup Schedule Install a regular backup schedule that fits your organization’s needs . The frequency of backups may depend on how often your data changes. 7b. Choose Suitable Backup Methods You can choose from backup methods such as snapshots, replication, or traditional backups. Each method has its own benefits and limitations. 7c. Implement a Data Recovery Strategy In addition to backing up your data, you need a solid strategy for restoring that data if a loss occurs. This includes determining recovery objectives. 7d. Test Your Backup and Recovery Plan Regular testing is crucial to ensuring your backup and recovery plan works. Test different scenarios, such as recovering a single file or a whole system. 7e. Secure Your Backups Backups can become cybercriminals’ targets, so they also need to be secured. This includes using encryption to protect backup data and implementing access controls. 8. Use Malware Protection Implementing robust malware protection measures is pivotal in data security. It’s important to maintain up-to-date malware protection and routinely scan your systems. 8a. Deploy Antimalware Software Deploy antimalware software across your cloud environment. This software can detect, quarantine, and eliminate malware threats.

Hybrid Cloud Security Management Deconstructing the Complexity of Managing Hybrid Cloud Security Tsippi Dach 2 min read Tsippi Dach Short bio about author here Lorem ipsum dolor sit amet consectetur. Vitae donec tincidunt elementum quam laoreet duis sit enim. Duis mattis velit sit leo diam. Tags Share this article 4/4/22 Published The move from traditional data centers to a hybrid cloud network environment has revolutionized the way enterprises construct their networks, allowing them to reduce hardware and operational costs, scale per business needs and be more agile. When enterprises choose to implement a hybrid cloud model, security is often one of the primary concerns. The additional complexity associated with a hybrid cloud environment can, in turn, make securing resources to a single standard extremely challenging. This is especially true when it comes to managing the behavioral and policy nuances of business applications . Moreover, hybrid cloud security presents an even greater challenge when organizations are unable to fully control the lifecycle of the public cloud services they are using. For instance, when an organization is only responsible for hosting a portion of its business-critical workloads on the public cloud and has little to no control over the hosting provider, it is unlikely to be able to enforce consistent security standards across both environments. Managing hybrid cloud security Hybrid cloud security requires an extended period of planning and investment for enterprises to become secure. This is because hybrid cloud environments are inherently complex and typically involve multiple providers. To effectively manage these complex environments, organizations will require a comprehensive approach to security that addresses each of the following challenges: Strategic planning and oversight : Policy design and enforcement across hybrid clouds Managing multiple vendor relationships and third-party security controls : Cloud infrastructure security controls, security products provided by cloud and third-party providers and third-party on-premise security vendor products. Managing security-enabling technologies in multiple environments : on-premise, public cloud and private cloud. Managing multiple stakeholders : CISO, IT/Network Security, SecOps, DevOps and Cloud teams. Workflow automation : Auto responding to changing business demands requiring provisioning of policy changes automatically and securely across the hybrid cloud estate. Optimizing security and agility : Aligning risk tolerance with the DevOps teams to manage business application security and connectivity. With these challenges in mind, here are 5 steps you can take to effectively address hybrid cloud security challenges. Step 1. Define the security objectives A holistic approach to high availability is focused on the two critical elements of any hybrid cloud environment: technology and processes. Defining a holistic strategy in a hybrid cloud environment has these advantages: Improved operational availability : Ensure continuous application connectivity, data, and system availability across the hybrid estate. Reduced risk : Understand threats to business continuity from natural disasters or facility disruptions. Better recovery : Maintain data consistency by mirroring critical data between primary locations in case of failure at one site through multiple backup sites. Step 2. Visualize the entire network topology The biggest potential point of failure for hybrid cloud deployment is where the public cloud and private environment offerings meet. This can result in a visual gap often due to disparities between in-house security protocols and third-party security standards, precluding SecOps teams from securing the connectivity of business applications. The solution lies in gaining complete visibility across the entire hybrid cloud estate. This requires having the right solution in place that can help SecOps teams discover, track and migrate application connectivity without regard for the underlying infrastructure. Step 3. Use automation for adaptability and scalability The ability to adapt and scale on demand is one of the most significant advantages of a hybrid cloud environment. Invariably, when considering the range of benefits of a hybrid cloud, it is difficult to conceptualize the power of scaling on demand. Still, enterprises can enjoy tremendous benefits when they correctly implement automation that can respond on-demand to necessary changes. With the right change automation solution, change requests can be easily defined and pushed through the workflow without disrupting the existing network security policy rules or introducing new potential risks. Step 4. Minimize the learning curb According to a 2021 Global Knowledge and IT Skills report , 76% of IT decision-makers experience critical skills gaps in their teams. Hybrid cloud deployment is a complicated process, with the largest potential point of failure being where in-house security protocols and third-party standards interact. If this gap is not closed, malicious actors or malware could slip through it. Meeting this challenge requires a unification of all provisions made to policy changes so that SecOps teams can become familiar with them, regardless of any new device additions to the network security infrastructure. This would be applicable to provisions associated with policy changes across all firewalls, segments, zones, micro‐segments, security groups and zones, and within each business application. Step 5. Get compliant Compliance cannot be guaranteed when the enterprise cannot monitor all vendors and platforms or enforce their policies in a standard manner. This can be especially challenging when attempting to apply compliance standardizations across an infrastructure that consists of a multi-vendor hybrid network environment. To address this issue, enterprises must get their SecOps teams to shift their focus away from pure technology management and toward a larger scale view that ensures that their network security policies consistently comply with regulatory requirements across the entire hybrid cloud estate. Summary Hybrid cloud security presents a significant—and often overlooked—challenge for enterprises. This is because hybrid cloud environments are inherently complex, involving multiple providers, and impact how enterprises manage their business applications and overall IT assets.

Cyber Attacks & Incident Response How to improve network security (7 fundamental ways) Tsippi Dach 2 min read Tsippi Dach Short bio about author here Lorem ipsum dolor sit amet consectetur. Vitae donec tincidunt elementum quam laoreet duis sit enim. Duis mattis velit sit leo diam. Tags Share this article 8/9/23 Published As per Cloudwards , a new organization gets hit by ransomware every 14 seconds. This is despite the fact that global cybersecurity spending is up and is around $150 billion per year. That’s why fortifying your organization’s network security is the need of the hour. Learn how companies are proactively improving their network security with these best practices. 7 Ways to improve network security: ` 1. Change the way you measure cyber security risk Cyber threats have evolved with modern cybersecurity measures. Thus, legacy techniques to protect the network are not going to work. These techniques include measures like maturity assessment, compliance attestation, and vulnerability aging reports, among other things. While they still have a place in cybersecurity, they’re insufficient. To level up, you need greater visibility over the various risk levels. This visibility will allow you to deploy resources as per need. At the bare minimum, companies need a dashboard that lists real-time data on the number of applications, the region they’re used in, the size and nature of the database, the velocity of M&A, etc. IT teams can make better decisions since the impact of new technologies like big data and AI falls unevenly on organizations. Along with visibility, companies need transparency and precision on how the tools behave against cyberattacks. You can use the ATT&CK Framework developed by MITRE Corporation, the most trustworthy threat behavior knowledge base available today. Use it as a benchmark to test the tools’ efficiency. Measuring the tools this way helps you prepare well in advance. Another measurement technique you must adopt is measuring performance against low-probability, high-consequence attacks. Pick the events that you conclude have the least chance of occurring. Then, test the tools on such attacks. Maersk learned this the hard way. In the notPetya incident , the company came pretty close to losing all of its IT data. Imagine the consequence it’d have on the company that handles the world’s supply chain. Measuring is the only way to learn whether your current cybersecurity arrangements meet the need. 2. Use VLAN and subnets An old saying goes, ‘Don’t keep all your eggs in the same basket.’ Doing so would mean losing the basket, losing all your eggs. That is true for IT networks as well. Instead of treating your network as a whole, divide it into multiple subnetworks. There are various ways you can do that: VLAN or Virtual LAN is one of them. VLAN helps you segment a physical network without investing in additional servers or devices. The different segments can then be handled differently as per the need. For example, the accounting department will have a separate segment, and so will the marketing and sales departments. This segmentation helps enhance security and limit damage. VLAN also helps you prioritize data, networks, and devices. There will be some data that is more critical than others. The more critical data warrant better security and protection, which you can provide through a VLAN partition. Subnets are another way to segment networks. As opposed to VLAN, which separates the network at the switch level, subnets partition the network at IP level or level 3. The various subnetworks can then communicate with each other and third-party networks over IP. With the adoption of technologies like the Internet of Things (IoT), network segmentation is only going to get more critical. Each device used for data generation, like smartwatches, sensors, and cameras, can act as an entry point to your network. If the entry points are connected to sensitive data like consumers’ credit cards, it’s a recipe for disaster. You can implement VLAN or subnets in such a scenario. 3. Use NGFWs for cloud The firewall policy is at the core of cybersecurity. They’re essentially the guardians who check for intruders before letting the traffic inside the network. But with the growth of cloud technologies and the critical data they hold, traditional firewalls are no longer reliable. They can easily be passed by modern malware. You must install NGFWs or Next Generation Firewalls in your cloud to ensure total protection. These firewalls are designed specifically to counter modern cyberattacks. An NGFW builds on the capabilities of a traditional firewall. Thus, it inspects all the incoming traffic. But in addition, it has advanced capabilities like IPS (intrusion prevention system), NAT (network address translation), SPI (stateful protocol inspection), threat intelligence feeds, container protection, and SSL decryption, among others. NGFWs are also both user and application-aware. This allows them to provide context on the incoming traffic. NGFWs are important not only for cloud networks but also for hybrid networks . Malware from the cloud could easily transition into physical servers, posing a threat to the entire network. When selecting a next-gen firewall for your cloud, consider the following security features: The speed at which the firewall detects threats. Ideally, it should identify the attacks in seconds and detect data breaches within minutes. The number of deployment options available. The NGFW should be deployable on any premise, be it a physical, cloud, or virtual environment. Also, it should support different throughput speeds. The home network visibility it offers. It should report on the applications and websites, location, and users. In addition, it should show threats across the separate network in real-time. The detection capabilities. It goes without saying, but the next-gen firewall management should detect novel malware quickly and act as an anti-virus. Other functionalities that are core security requirements. Every business is different with its unique set of needs. The NGFW should fulfill all the needs. 4. Review and keep IAM updated To a great extent, who can access what determines the security level of a network. As a best practice, you should grant access to users as per their roles and requirement — nothing less, nothing more. In addition, it’s necessary to keep IAM updated as the role of users evolves. IAM is a cloud service that controls unauthorized access for users. The policies defined in this service either grant or reject resource access. You need to make sure the policies are robust. This requires you to review your IT infrastructure, the posture, and the users at the organization. Then create IAM policies and grant access as per the requirement. As already mentioned, users should have remote access to the resources they need. Take that as a rule. Along with that, uphold these important IAM principles to improve access control and overall network security strategy: Zero in on the identity It’s important to identify and verify the identity of every user trying to access the network. You can do that by centralizing security control on both user and service IDs. Adopt zero-trust Trust no one. That should be the motto when handling a company’s network security. It’s a good practice to assume every user is untrustworthy unless proven otherwise. Therefore, have a bare minimum verification process for everyone. Use MFA MFA or multi-factor authentication is another way to safeguard network security. This could mean they have to provide their mobile number or OTA pin in addition to the password. MFA can help you verify the user and add an additional security layer. Beef up password Passwords are a double-edged sword. They protect the network but also pose a threat when cracked. To prevent this, choose strong passwords meeting a certain strength level. Also, force users to update their unique passwords regularly. If possible, you can also go passwordless. This involves installing email-based or biometric login systems. Limit privileged accounts Privileged accounts are those accounts that have special capabilities to access the network. It’s important to review such accounts and limit their number. 5. Always stay in compliance Compliance is not only for pleasing the regulators. It’s also for improving your network security. Thus, do not take compliance for granted; always make your network compliant with the latest standards. Compliance requirements are conceptualized after consulting with industry experts and practitioners. They have a much better authoritative position to discuss what needs to be done at an industry level. For example, in the card sector, it’s compulsory to have continuous penetration testing done. So, when fulfilling a requirement, you adopt the best practices and security measures. The requirements don’t remain static. They evolve and change as loopholes emerge. The new set of compliance frameworks helps ensure you’re up-to-date with the latest standards. Compliance is also one of the hardest challenges to tackle. That’s because there are various types of compliances. There are government-, industry-, and product-level compliance requirements that companies must keep up with. Moreover, with hybrid networks and multi-cloud workflows, the task only gets steeper. Cloud security management tools can help in this regard to some extent. Since they grant a high level of visibility, spotting non-compliance becomes easier. Despite the challenges, investing more is always wise to stay compliant. After all, your business reputation depends on it. 6. Physically protect your network You can have the best software or service provider to protect your wireless networks and access points. But they will still be vulnerable if physical protection isn’t in place. In the cybersecurity space, the legend has it that the most secure network is the one that’s behind a closed door. Any network that has humans nearby is susceptible to cyberattacks. Therefore, make sure you have appropriate security personnel at your premises. They should have the capability and authority to physically grant or deny access to those seeking access to the network on all operating systems. Make use of biometric IDs to identify the employees. Also, prohibit the use of laptops, USB drives, and other electronic gadgets that are not authorized. When creating a network, data security teams usually authorize each device that can access it. This is known as Layer 1. To improve network security policy , especially on Wi-Fi (WPA), ensure all the network devices and workstations and SSIDs connected to the network as trustworthy. Adopt the zero-trust security policies for every device: considered untrustworthy until proven otherwise. 7. Train and educate your employees Lastly, to improve network security management , small businesses must educate their employees and invest in network monitoring. Since every employee is connected to the Wi-Fi network somehow, everyone poses a security threat. Hackers often target those with privileged access. Such accounts, once exploited by cybercriminals, can be used to access different segments of the network with ease. Thus, such personnel should receive education on priority. Train your employees on attacks like phishing, spoofing, code injection, DNS tunneling, etc. With knowledge, employees can tackle such attempts head-on. This, in turn, makes the network much more secure. After the privileged account holders are trained, make others in your organization undergo the same training. The more educated they are, the better it is for the network. It’s worth reviewing their knowledge of cybersecurity from time to time. You can conduct a simple survey in Q&A format to test the competency of your team. Based on the results, you can hold training sessions and get everyone on the same page. The bottom line on network security Data breaches often come at a hefty cost. And the most expensive item on the list is the trust of users. Once a data leak happens, retaining customers’ trust is very hard. Regulators aren’t easy on the executives either. Thus, the best option is to safeguard and improve your network security .

This includes ensuring access to corporate data is secured, connectivity to the data center from both internal and external users is secured, and that critical security updates are installed. Now comes the big question: what if you have to migrate your security policy to a new platform? With cloud computing and distributed data centers across the world nothing in technology is ever constant anymore. So how do you control and manage a firewall migration? What if you use multiple vendors’ solutions with both virtual and physical appliances? A firewall migration can be as simple as moving from one model to another, or a lot more complicated. As an experienced cloud architect, I’ve been a part of a number of firewall migration projects. Here are three tips to help make your firewall migration project a little bit easier. Create powerful firewall and security visibility map. All aspects of your firewall must be documented and well planned before doing a migration, and you must plan for both current as well as future needs. Start by gathering information: create a visual, dynamic map of your firewall architecture and traffic, which should include all technical connectivity data. Understand, document and prepare policy migration. Once you have your visual firewall map it’s time to look under the hood. One firewall might be easy, but is it ever really just one security appliance? The dynamic nature of the modern data center means that multiple security vendors can live under one roof. So how do you create a policy migration plan around heterogeneous platforms? You need to identify and document all the security policies and services and network algorithms for each firewall end-point. Analyze business impact and create a migration path. How do your applications interact with various security policies? Do you have specific business units relying on specific firewall traffic? How are various data centers being segmented by your security policies? Migrating a firewall will have a business-wide impact. You must ensure that this impact is absolutely minimal. You need to understand how your entire business model interacts with firewall and security technologies and if any piece of the business is forgotten technological headaches may be the least of your worries. Migrating a firewall doesn’t have to be hard, but it must be well planned. With so much information traversing the modern data center, it’s imperative to have complete visibility across the security architecture. Ultimately, with the right tools to help you plan, map and actually implement a firewall change process, and lots of cups of coffee, you can greatly reduce security migration complexity. #FirewallMigration Schedule a demo Related Articles Q1 at AlgoSec: What innovations and milestones defined our start to 2026?

Cloud Security Top 5 Tips on Avoiding Cloud Misconfigurations Rony Moshkovich 2 min read Rony Moshkovich Short bio about author here Lorem ipsum dolor sit amet consectetur. Vitae donec tincidunt elementum quam laoreet duis sit enim. Duis mattis velit sit leo diam. Tags Share this article 11/24/22 Published Cloud misconfigurations can cause devastating financial and reputational damage to organizations. Yet, such undesirable circumstances can be avoided by understanding common misconfiguration errors and mitigating them before malicious actors can exploit them. Ava Chawla, AlgoSec’s Global Head of Cloud Security provides some valuable insights on cloud misconfigurations and offers useful tips on how to avoid them It may come as a surprise to some, but did you know that misconfigurations were the #1 cause of cloud-security incidents in 2021 and were also responsible for 65-70% of cloud-security challenges in 2020? Cloud Misconfigurations: The Insidious yet Serious Threat Clearly, misconfigurations are a common cause of security loopholes. These security loopholes – usually the result of oversights, errors, or poor configuration choices by inexperienced or careless users – often result in cyberattacks and the exposure of mission-critical information. Most cloud environments are saturated with misconfigurations, with 99% of them going unseen. As a result, they become vulnerable to many cyberthreats, including malware, ransomware, and insider threats. Threat actors may also exploit the vulnerabilities caused by misconfigurations to access enterprise networks, compromise assets, or exfiltrate sensitive data. So why are cloud misconfigurations such a serious threat in cloud environments? And, how can your organization avoid these errors and keep your cloud environment safe from the bad guys? Jarring Data Breaches Resulting from Cloud Misconfigurations: More than Food for Thought In 2018 and 2019 , misconfigurations caused hundreds of data breaches that cost companies a whopping $5 trillion. Threat actors also took advantage of misconfigurations to attack many organizations in 2020. An exposed database is a perfect example of how misconfiguration errors like forgetting to password-protect critical cloud assets can create huge security risks for companies. In early 2020, a database belonging to cosmetics giant Estée Lauder that contained over 440 million records ended up online – all because it was not password-protected. How bad was this oversight? It allowed malicious actors to access its sensitive contents, such as email addresses, middleware records, references to internal documents, and information about company IP addresses and ports. And misconfiguration-related breaches didn’t stop in 2021. In May of that year, Cognyte left a database unsecured, leading to the online exposure of 5 billion records, including names, passwords, and email addresses. The incident is particularly ironic because Cognyte is a cyber-intelligence service that alerts users to potential data breaches. So how can your organization avoid suffering the same fates as Estée Lauder and Cognyte? By preventing misconfiguration errors. How to Eliminate Common Misconfiguration Errors? 1) One of the most common cloud misconfiguration errors is not implementing monitoring . A failure to monitor the cloud environment creates huge security risks because the organization can’t even know that there’s a threat, much less mitigate it. Solution: By integrating monitoring and logging tools into your entire cloud estate, you can keep an eye on all the activity happening within it. More importantly, you can identify suspicious or malicious actions, and act early to mitigate threats and prevent serious security incidents. An example of a monitoring tool is CloudTrail in the AWS Cloud. 2) The second-biggest misconfiguration risk stems from overly permissive access settings. Enterprise teams frequently forget to change the default settings or make the settings overly-permissive, resulting in critical assets being exposed to the Internet and to threat actors lurking in cyberspace. 3) Another misconfiguration mistake is mismanaging identity and access management (IAM) roles and permissions. Unrestricted access, particularly admin-level access, significantly increases the probability of breaches. The compromise of this user could allow a malicious actor to exploit the entire network and its sensitive data. 4) Mismanaged secrets are another common misconfiguration mistake that can lead to attacks and breaches. Secrets like passwords, API keys, encryption keys, and access tokens are the keys to your (cloud) kingdom, and their compromise or theft can severely damage your enterprise. Solution: You can avoid mistakes #2, #3 and #4 by granting least-privilege access (also known as the principle of least privilege) and implementing detailed security policies, standards, and procedures for IAM, secrets management, remote access, etc. 5) The fifth misconfiguration error is not patching vulnerabilities. Patch management pitfalls include pushing out updates too quickly and devices going offline. But the most significant risk when patch management doesn’t take place, not surprisingly, is leaving a system vulnerable to malicious actors. Solution: Proactively scanning your cloud environment is vital to find the vulnerabilities that can be exploited by threat actors to elevate their privileges in your network and execute remote attacks. Conclusion and Next Steps Cloud misconfigurations are the most common cause of security incidents in the cloud. Fortunately, most of them are avoidable. If you’ve found this action-packed guide a valuable read, then you’re on the right path to reaching a solution that includes protecting your most valuable assets, securing the connectivity of your most critical business applications, and streamlining the management of your entire multi cloud environment.

Uncategorized How To Prevent Firewall Breaches (The 2024 Guide) Tsippi Dach 2 min read Tsippi Dach Short bio about author here Lorem ipsum dolor sit amet consectetur. Vitae donec tincidunt elementum quam laoreet duis sit enim. Duis mattis velit sit leo diam. Tags Share this article 1/11/24 Published Properly configured firewalls are vital in any comprehensive cybersecurity strategy. However, even the most robust configurations can be vulnerable to exploitation by attackers. No single security measure can offer absolute protection against all cyber threats and data security risks . To mitigate these risks, it’s crucial to understand how cybercriminals exploit firewall vulnerabilities. The more you know about their tactics, techniques, and procedures, the better-equipped you are to implement security policies that successfully block unauthorized access to network assets. In this guide, you’ll understand the common cyber threats that target enterprise firewall systems with the goal of helping you understand how attackers exploit misconfigurations and human vulnerabilities. Use this information to protect your network from a firewall breach. Understanding 6 Tactics Cybercriminals Use to Breach Firewalls 1. DNS Leaks Your firewall’s primary use is making sure unauthorized users do not gain access to your private network and the sensitive information it contains. But firewall rules can go both ways – preventing sensitive data from leaving the network is just as important. If enterprise security teams neglect to configure their firewalls to inspect outgoing traffic, cybercriminals can intercept this traffic and use it to find gaps in your security systems. DNS traffic is particularly susceptible to this approach because it shows a list of websites users on your network regularly visit. A hacker could use this information to create a spoofed version of a frequently visited website. For example, they might notice your organization’s employees visit a third-party website to attend training webinars. Registering a fake version of the training website and collecting employee login credentials would be simple. If your firewall doesn’t inspect DNS data and confirm connections to new IP addresses, you may never know. DNS leaks may also reveal the IP addresses and endpoint metadata of the device used to make an outgoing connection. This would give cybercriminals the ability to see what kind of hardware your organization’s employees use to connect to external websites. With that information in hand, impersonating managed service providers or other third-party partners is easy. Some DNS leaks even contain timestamp data, telling attackers exactly when users requested access to external web assets. How to protect yourself against DNS leaks Proper firewall configuration is key to preventing DNS-related security incidents. Your organization’s firewalls should provide observability and access control to both incoming and outgoing traffic. Connections to servers known for hosting malware and cybercrime assets should be blocked entirely. Connections to servers without a known reputation should be monitored closely. In a Zero Trust environment , even connections to known servers should benefit from scrutiny using an identity-based security framework. Don’t forget that apps can connect to external resources, too. Consider deploying web application firewalls configured to prevent DNS leaks when connecting to third-party assets and servers. You may also wish to update your security policy to require employees to use VPNs when connecting to external resources. An encrypted VPN connection can prevent DNS information from leaking, making it much harder for cybercriminals to conduct reconnaissance on potential targets using DNS data. 2. Encrypted Injection Attacks Older, simpler firewalls analyze traffic by looking at different kinds of data packet metadata. This provides clear evidence of certain denial-of-service attacks, clear violations of network security policy , and some forms of malware and ransomware . They do not conduct deep packet inspection to identify the kind of content passing through the firewall. This provides cybercriminals with an easy way to bypass firewall rules and intrusion prevention systems – encryption . If malicious content is encrypted before it hits the firewall, it may go unnoticed by simple firewall rules. Only next-generation firewalls capable of handling encrypted data packets can determine whether this kind of traffic is secure or not. Cybercriminals often deliver encrypted injection attacks through email. Phishing emails may trick users into clicking on a malicious link that injects encrypted code into the endpoint device. The script won’t decode and run until after it passes the data security threshold posed by the firewall. After that, it is free to search for personal data, credit card information, and more. Many of these attacks will also bypass antivirus controls that don’t know how to handle encrypted data. Task automation solutions like Windows PowerShell are also susceptible to these kinds of attacks. Even sophisticated detection-based security solutions may fail to recognize encrypted injection attacks if they don’t have the keys necessary to decrypt incoming data. How to protect yourself against encrypted injection attacks Deep packet inspection is one of the most valuable features next-generation firewalls provide to security teams. Industry-leading firewall vendors equip their products with the ability to decrypt and inspect traffic. This allows the firewall to prevent malicious content from entering the network through encrypted traffic, and it can also prevent sensitive encrypted data – like login credentials – from leaving the network. These capabilities are unique to next-generation firewalls and can’t be easily replaced with other solutions. Manufacturers and developers have to equip their firewalls with public-key cryptography capabilities and obtain data from certificate authorities in order to inspect encrypted traffic and do this. 3. Compromised Public Wi-Fi Public Wi-Fi networks are a well-known security threat for individuals and organizations alike. Anyone who logs into a password-protected account on public Wi-Fi at an airport or coffee shop runs the risk of sending their authentication information directly to hackers. Compromised public Wi-Fi also presents a lesser-known threat to security teams at enterprise organizations – it may help hackers breach firewalls. If a remote employee logs into a business account or other asset from a compromised public Wi-Fi connection, hackers can see all the data transmitted through that connection. This may give them the ability to steal account login details or spoof endpoint devices and defeat multi-factor authentication. Even password-protected private Wi-Fi connections can be abused in this way. Some Wi-Fi networks still use outdated WEP and WPA security protocols that have well-known vulnerabilities. Exploiting these weaknesses to take control of a WEP or WPA-protected network is trivial for hackers. The newer WPA2 and WPA3 standards are much more resilient against these kinds of attacks. While public Wi-Fi dangers usually bring remote workers and third-party service vendors to mind, on-premises networks are just as susceptible. Nothing prevents a hacker from gaining access to public Wi-Fi networks in retail stores, receptions, or other areas frequented by customers and employees. How to protect yourself against compromised public Wi-Fi attacks First, you must enforce security policies that only allow Wi-Fi traffic secured by WPA2 and WPA3 protocols. Hardware Wi-Fi routers that do not support these protocols must be replaced. This grants a minimum level of security to protected Wi-Fi networks. Next, all remote connections made over public Wi-Fi networks must be made using a secure VPN. This will encrypt the data that the public Wi-Fi router handles, making it impossible for a hacker to intercept without gaining access to the VPN’s secret decryption key. This doesn’t guarantee your network will be safe from attacks, but it improves your security posture considerably. 4. IoT Infrastructure Attacks Smartwatches, voice-operated speakers, and many automated office products make up the Internet of Things (IoT) segment of your network. Your organization may be using cloud-enriched access control systems, cost-efficient smart heating systems, and much more. Any Wi-Fi-enabled hardware capable of automation can safely be included in this category. However, these devices often fly under the radar of security team’s detection tools, which often focus on user traffic. If hackers compromise one of these devices, they may be able to move laterally through the network until they arrive at a segment that handles sensitive information. This process can take time, which is why many incident response teams do not consider suspicious IoT traffic to be a high-severity issue. IoT endpoints themselves rarely process sensitive data on their own, so it’s easy to overlook potential vulnerabilities and even ignore active attacks as long as the organization’s mission-critical assets aren’t impacted. However, hackers can expand their control over IoT devices and transform them into botnets capable of running denial-of-service attacks. These distributed denial-of-service (DDoS) attacks are much larger and more dangerous, and they are growing in popularity among cybercriminals. Botnet traffic associated with DDoS attacks on IoT networks has increased five-fold over the past year , showing just how promising it is for hackers. How to protect yourself against IoT infrastructure attacks Proper network segmentation is vital for preventing IoT infrastructure attacks . Your organization’s IoT devices should be secured on a network segment that is isolated from the rest of the network. If attackers do compromise the entire network, you should be protected from the risk of losing sensitive data from critical business assets. Ideally, this protection will be enforced with a strong set of firewalls managing the connection between your IoT subnetwork and the rest of your network. You may need to create custom rules that take your unique security risk profile and fleet of internet-connected devices into account. There are very few situations in which one-size-fits-all rulemaking works, and this is not one of them. All IoT devices – no matter how small or insignificant – should be protected by your firewall and other cybersecurity solutions . Never let these devices connect directly to the Internet through an unsecured channel. If they do, they provide attackers with a clear path to circumvent your firewalls and gain access to the rest of your network with ease. 5. Social Engineering and Phishing Social engineering attacks refer to a broad range of deceptive practices used by hackers to gain access to victims’ assets. What makes this approach special is that it does not necessarily depend on technical expertise. Instead of trying to hack your systems, cybercriminals are trying to hack your employees and company policies to carry out their attacks. Email phishing is one of the most common examples. In a typical phishing attack , hackers may spoof an email server to make it look like they are sending emails from a high-level executive in the company you work for. They can then impersonate this executive and demand junior accountants pay fictitious invoices or send sensitive customer data to email accounts controlled by threat actors. Other forms of social engineering can use your organization’s tech support line against itself. Attackers may pretend to represent large customer accounts and will leverage this ruse to gain information about how your company works. They may impersonate a third-party vendor and request confidential information that the vendor would normally have access to. These attacks span the range from simple trickery to elaborate confidence scams. Protecting against them can be incredibly challenging, and your firewall capabilities can make a significant difference in your overall state of readiness. How to protect yourself against social engineering attacks Employee training is the top priority for protecting against social engineering attacks . When employees understand the company’s operating procedures and security policies, it’s much harder for social engineers to trick them. Ideally, training should also include in-depth examples of how phishing attacks work, what they look like, and what steps employees should take when contacted by people they don’t trust. 6. Sandbox Exploits Many organizations use sandbox solutions to prevent file-based malware attacks. Sandboxes work by taking suspicious files and email attachments and opening them in a secure virtual environment before releasing them to users. The sandbox solution will observe how the file behaves and quarantine any file that shows malicious activity. In theory, this provides a powerful layer of defense against file-based attacks. But in practice, cybercriminals are well aware of how to bypass these solutions. For example, many sandbox solutions can’t open files over a certain size. Hackers who attach malicious code to large files can easily get through. Additionally, many forms of malware do not start executing malicious tasks the second they are activated. This delay can provide just enough of a buffer to get through a sandbox system. Some sophisticated forms of malware can even detect when they are being run in a sandbox environment – and will play the part of an innocent program until they are let loose inside the network. How to protect yourself against sandbox exploits Many next-generation firewalls include cloud-enabled sandboxing capable of running programs of arbitrary size for a potentially unlimited amount of time. More sophisticated sandbox solutions go to great lengths to mimic the system specifications of an actual endpoint so malware won’t know it is being run in a virtual environment. Organizations may also be able to overcome the limitations of the sandbox approach using Content Disarm and Reconstruction (CDR) techniques. This approach keeps potentially malicious files off the network entirely and only allows a reconstructed version of the file to enter the network. Since the new file is constructed from scratch, it will not contain any malware that may have been attached to the original file.

- AlgoSec | What is a Cloud-Native Application Protection Platform (CNAPP)
Cloud environments are complex and dynamic. Due to the complexity and multifacetedness of cloud technologies, cloud-native applications... Cloud Security What is a Cloud-Native Application Protection Platform (CNAPP) Ava Chawla 2 min read Ava Chawla Short bio about author here Lorem ipsum dolor sit amet consectetur. Vitae donec tincidunt elementum quam laoreet duis sit enim. Duis mattis velit sit leo diam. Tags Share this article 11/24/22 Published Cloud environments are complex and dynamic. Due to the complexity and multifacetedness of cloud technologies, cloud-native applications are challenging to safeguard. As a result, security teams use multiple security solutions, like CWPP and CSPM, to protect applications. The problem with this approach is that handling multiple security tools is laborious, time-consuming, and inefficient. Cloud-native application protection platform (CNAPP) is a new cloud security solution that promises to solve this problem. What is CNAPP? A cloud-native application protection platform (CNAPP) is an all-in-one tool with the capabilities of different cloud-native security tools. It combines the security features of multiple tools and provides comprehensive protection – from the development and configuration stages to deployment and runtime. Container security is here to stay A CNAPP combines CSPM, CIEM, IAM, CWPP, and more in one tool. It streamlines cloud security monitoring, threat detection, and remediation processes. The all-in-one platform gives organizations better visibility into threats and vulnerabilities. Instead of using multiple tools to receive alerts and formulate a remediation plan, a CNAPP minimizes complexity and enables security teams to monitor and draw insights from a single platform. How Does CNAPP Work and Why is it So Important to Have? This new cloud security approach offers the capabilities of multiple security tools in one software. Some of these security functions include Cloud Security Posture Management (CSPM), Infrastructure-as-Code (IaC) Scanning, Cloud Workload Protection Platform (CWPP), Cloud Network Security Connectivity (CNSC), and Kubernetes Security Posture Management (CIEM). The all-in-one platform centralizes insights, enabling security professionals to monitor and analyze data from the same space. A CNAPP identifies risks with strong context, provides detailed alerts, and offers automation features to fix vulnerabilities and misconfigurations. A CNAPP is essential because it reduces complexity and minimizes overhead. Given how complex and dynamic the cloud environments are, organizations are faced with enormous security threats. Enterprises deploy applications on multiple private and public clouds leveraging various dynamic, mixed technologies. This makes securing cloud assets significantly challenging. To cope with the complexity, security operations teams rely on multiple cloud security solutions. SecOps use various solutions to protect modern development practices, such as containers, Kubernetes, serverless functions, CI/CD pipelines, and infrastructure as code (IaC). This approach has been helpful. That said, it’s laborious and inefficient. In addition to not providing a broad view of security risks, dealing with multiple tools negatively impacts accuracy and decreases productivity. Having to correlate data from several platforms leads to errors and delayed responses. A CNAPP takes care of these problems by combining the functionalities of multiple tools in one software. It protects every stage of the cloud application lifecycle, from development to runtime. Leveraging advanced analytics and remediation automation, CNAPPs help organizations address cloud-native risks, harden applications, and institute security best practices. What Problems Does a CNAPP Solve? This new category of cloud application security tool is revolutionizing the cybersecurity landscape. It solves major challenges DevSecOps have been dealing with. That said, a CNAPP helps security teams to solve the following problems. 1. Enhancing Visibility and Quantifying Risks A CNAPP offers a broader visibility of security risks. It leverages multiple security capabilities to enable DevOps and DevSecOps to spot and fix potential security issues throughout the entire application lifecycle. The all-in-one security platform enables teams to keep tabs on all cloud infrastructures ( like apps, APIs, and classified data) and cloud services (like AWS, Azure, and Google Cloud). In addition, it provides insights that help security teams to quantify risks and formulate data-driven remediation strategies. 2. Combined Cloud Security Solution A CNAPP eliminates the need to use multiple cloud-native application protection solutions. It provides all the features needed to detect and solve security issues. Scanning, detection, notification, and reporting are consolidated in one software. This reduces human error, shortens response time, and minimizes the cost of operation. 3. Secure Software Development It reinforces security at every stage of the application lifecycle. The tool helps DevOps teams to shift left, thus minimizing the incidence of vulnerabilities or security issues at runtime. 4. Team Collaboration Collaboration is difficult and error-prone when teams are using multiple tools. Data correlation and analysis take more time since team members have more than one tool to deal with. A CNAPP is a game-changer! It has advanced workflows, data correlation, analytics, and remediation features. These functionalities enhance team collaboration and increase productivity. What are CNAPP Features and Capabilities/Key Components of CNAPP? Even though the features and capabilities of CNAPPs differ (based on vendors), there are key components an effective CNAPP should have. That being said, here are the seven key components: Cloud Security Posture Management (CSPM) A CSPM solution focuses on maintaining proper cloud configuration. It monitors, detects, and fixes misconfigurations & compliance violations. CSPM monitors cloud resources and alerts security teams when a non-compliant resource is identified. Infrastructure-as-Code (IaC) Scanning IaC Scanning enables the early detection of errors (misconfigurations) in code. Spotting misconfigurations before deployment helps to avoid vulnerabilities at runtime. This tool is used to carry out some kind of code review. The purpose is to ensure code quality by scanning for vulnerable points, compliance issues, and violations of policies. Cloud Workload Protection Platform (CWPP) Cloud workload protection platform (CSPM) secures cloud workloads, shielding your resources from security threats. CSPM protects various workloads, from virtual machines (VMs) and databases to Kubernetes and containers. A CWPP monitors and provides insights to help security teams prevent security breaches. Cloud Network Security Connectivity (CNSC) Cloud Network Security Connectivity (CNSC) provides complete real-time visibility and access to risks across all your cloud resources and accounts. This cloud security solution allows you to explore the risks, activate security rules, and suppress whole risks or risk triggers, export risk trigger details, access all network rules in the context of their policy sets and create risk reports. Kubernetes Security Posture Management (KSPM) Kubernetes security posture management (KSPM) capability enables organizations to maintain standard security posture by preventing Kubernetes misconfigurations and compliance violations. KSPM solution, similar to Cloud Security Posture Management (CSPM), automates Kubernetes security, reinforces compliance, identifies misconfigurations, and monitors Kubernetes clusters to ensure maximum security. Cloud Infrastructure Entitlement Management (CIEM) A Cloud Infrastructure Entitlement Management (CIEM) tool is used to administer permissions and access policies. To maintain the integrity of cloud and multi-cloud environments, identities and access privileges must be regulated. This is where CIEM comes in! CIEM solutions, also known as Cloud permissions Management Solutions, help organizations prevent data breaches by enforcing the principle of least privileges. Integration to Software Development Activities This component of CNAPP focuses on integrating cloud-native application protection solutions into the development phase to improve reliability and robustness in the CI/CD pipeline stage. What are the Benefits of CNAPP? Transitioning from using multiple cloud security tools to implementing a CNAPP solution can benefit your company in many ways. Some benefits include: 1. Streamlines Security Operations Managing multiple security tools decreases efficiency and leads to employee burnout. Correlating data from different software is laborious and error-prone. It prolongs response time. A CNAPP streamlines activities by giving security teams broad visibility from a single tool. This makes monitoring and remediation easier than ever – making security teams more efficient and productive. 2. Better Visibility into Risks A CNAPP provides better visibility into security risks associated with your cloud infrastructure. It covers all aspects of cloud-native application protection, providing security teams with the necessary insights to close security gaps, harden applications, and ward off threats. 3. Improves Security With Automation Risk detection and vulnerability management are automated. Automation of security tasks increases reliability, reduces human error, and enables rapid response to threats. It combines automation and advanced analytics to offer organizations accurate insights into risks. 4. Reduces the Number of Bug Fixes A CNAPP prevents vulnerabilities at runtime by detecting threats and errors in the CI/CD pipeline phases. This approach improves DevOps team productivity and decreases the number of bug fixes after deployment. In other words, shifting left ensures the deployment of high-quality code. 5. Reduces Overhead Costs If you want to cut down the cost of operation, consider choosing a CNAPP over CSPM and other standalone cloud security tools. It reduces overhead by eliminating the need to operate and maintain multiple cloud security solutions. AlgoSec CNAPP with Prevasio and CloudFlow Cloud environments are increasingly complex and dynamic. Maintaining secure cloud infrastructures has become more challenging than ever.

Vitae donec tincidunt elementum quam laoreet duis sit enim. Duis mattis velit sit leo diam. Tags Share this article 12/15/20 Published Update : Next two parts of the analysis are available here and here . As earlier reported by FireEye, the actors behind a global intrusion campaign have managed to trojanise SolarWinds Orion business software updates in order to distribute malware. The original FireEye write-up already provides a detailed description of this malware. Nevertheless, as the malicious update SolarWinds-Core-v2019.4.5220-Hotfix5.msp was still available for download for hours since the FireEye’s post, it makes sense to have another look into the details of its operation. The purpose of this write-up is to provide new information, not covered in the original write-up. Any overlaps with the original description provided by FireEye are not intentional. For start, the malicious component SolarWinds.Orion.Core.BusinessLayer.dll inside the MSP package is a non-obfuscated .NET assembly. It can easily be reconstructed with a .NET disassembler, such as ILSpy , and then fully reproduced in C# code, using Microsoft Visual Studio. Once reproduced, it can be debugged to better understand how it works. In a nutshell, the malicious DLL is a backdoor. It is loaded into the address space of the legitimate SolarWinds Orion process SolarWinds.BusinessLayerHost.exe or SolarWinds.BusinessLayerHostx64.exe . The critical strings inside the backdoor’s class SolarWinds.Orion.Core.BusinessLayer.OrionImprovementBusinessLayer are encoded with the DeflateStream Class of the .NET’s System.IO.Compression library, coupled with the standard base64 encoder. Initialisation Once loaded, the malware checks if its assembly file was created earlier than 12, 13, or 14 days ago. The exact number of hours it checks is a random number from 288 to 336. Next, it reads the application settings value ReportWatcherRetry . This value keeps the reporting status, and may be set to one of the states: New (4) Truncate (3) Append (5) When the malware runs the first time, its reporting status variable ReportWatcherRetry is set to New (4) . The reporting status is an internal state that drives the logic. For example, if the reporting status is set to Truncate , the malware will stop operating by first disabling its networking communications, and then disabling other security tools and antivirus products. In order to stay silent, the malware periodically falls asleep for a random period of time that varies between 30 minutes and 2 hours. At the start, the malware obtains the computer’s domain name . If the domain name is empty, the malware quits. It then generates a 8-byte User ID, which is derived from the system footprint. In particular, it is generated from MD5 hash of a string that consists from the 3 fields: the first or default operational (can transmit data packets) network interface’s physical address computer’s domain name UUID created by Windows during installation (machine’s unique ID) Even though it looks random, the User ID stays permanent as long as networking configuration and the Windows installation stay the same. Domain Generation Algorithm The malware relies on its own CryptoHelper class to generate a domain name. This class is instantiated from the 8-byte User ID and the computer’s domain name, encoded with a substitution table: “rq3gsalt6u1iyfzop572d49bnx8cvmkewhj” . For example, if the original domain name is “ domain “, its encoded form will look like: “ n2huov “. To generate a new domain, the malware first attempts to resolve domain name “ api.solarwinds.com “. If it fails to resolve it, it quits. The first part of the newly generated domain name is a random string, produced from the 8-byte User ID, a random seed value, and encoded with a custom base64 alphabet “ph2eifo3n5utg1j8d94qrvbmk0sal76c” . Because it is generated from a random seed value, the first part of the newly generated domain name is random. For example, it may look like “ fivu4vjamve5vfrt ” or “ k1sdhtslulgqoagy “. To produce the domain name, this string is then appended with the earlier encoded domain name (such as “ n2huov “) and a random string, selected from the following list: .appsync-api.eu-west-1[.]avsvmcloud[.]com .appsync-api.us-west-2[.]avsvmcloud[.]com .appsync-api.us-east-1[.]avsvmcloud[.]com .appsync-api.us-east-2[.]avsvmcloud[.]com For example, the final domain name may look like: fivu4vjamve5vfrtn2huov[.]appsync-api.us-west-2[.]avsvmcloud[.]com or k1sdhtslulgqoagyn2huov[.]appsync-api.us-east-1[.]avsvmcloud[.]com Next, the domain name is resolved to an IP address, or to a list of IP addresses. For example, it may resolve to 20.140.0.1 . The resolved domain name will be returned into IPAddress structure that will contain an AddressFamily field – a special field that specifies the addressing scheme. If the host name returned in the IPAddress structure is different to the queried domain name, the returned host name will be used as a C2 host name for the backdoor. Otherwise, the malware will check if the resolved IP address matches one of the patterns below, in order to return an ‘address family’: IP Address Subnet Mask ‘Address Family’ 10.0.0.0 255.0.0.0 Atm 172.16.0.0 255.240.0.0 Atm 192.168.0.0 255.255.0.0 Atm 224.0.0.0 240.0.0.0 Atm fc00:: fe00:: Atm fec0:: ffc0:: Atm ff00:: ff00:: Atm 41.84.159.0 255.255.255.0 Ipx 74.114.24.0 255.255.248.0 Ipx 154.118.140.0 255.255.255.0 Ipx 217.163.7.0 255.255.255.0 Ipx 20.140.0.0 255.254.0.0 ImpLink 96.31.172.0 255.255.255.0 ImpLink 131.228.12.0 255.255.252.0 ImpLink 144.86.226.0 255.255.255.0 ImpLink 8.18.144.0 255.255.254.0 NetBios 18.130.0.0 255.255.0.0 NetBios 71.152.53.0 255.255.255.0 NetBios 99.79.0.0 255.255.0.0 NetBios 87.238.80.0 255.255.248.0 NetBios 199.201.117.0 255.255.255.0 NetBios 184.72.0.0 255.254.0.0 NetBios For example, if the queried domain resolves to 20.140.0.1 , it will match the entry in the table 20.140.0.0 , for which the returned ‘address family’ will be ImpLink . The returned ‘address family’ invokes an additional logic in the malware. Disabling Security Tools and Antivirus Products If the returned ‘address family’ is ImpLink or Atm , the malware will enumerate all processes and for each process, it will check if its name matches one of the pre-defined hashes. Next, it repeats this processed for services and for the drivers installed in the system. If a process name or a full path of an installed driver matches one of the pre-defined hashes, the malware will disable it. For hashing, the malware relies on Fowler–Noll–Vo algorithm. For example, the core process of Windows Defender is MsMpEng.exe . The hash value of “ MsMpEng ” string is 5183687599225757871 . This value is specifically enlisted the malware’s source under a variable name timeStamps : timeStamps = new ulong[1] { 5183687599225757871uL } The service name of Windows Defender is windefend – the hash of this string ( 917638920165491138 ) is also present in the malware body. As a result, the malicioius DLL will attempt to stop the Windows Defender service. In order to disable various security tools and antivirus products, the malware first grants itself SeRestorePrivilege and SeTakeOwnershipPrivilege privileges, using the native AdjustTokenPrivileges() API. With these privileges enabled, the malware takes ownership of the service registry keys it intends to manipulate. The new owner of the keys is first attempted to be explicitly set to Administrator account. If such account is not present, the malware enumerates all user accounts, looking for a SID that represents the administrator account. The malware uses Windows Management Instrumentation query “ Select * From Win32_UserAccount ” to obtain the list of all users. For each enumerated user, it makes sure the account is local and then, when it obtains its SID, it makes sure the SID begins with S-1-5- and ends with -500 in order to locate the local administrator account. Once such account is found, it is used as a new owner for the registry keys, responsible for manipulation of the services of various security tools and antivirus products. With the new ownership set, the malware then disables these services by setting their Start value to 4 (Disabled): registryKey2.SetValue(“Start”), 4, RegistryValueKind.DWord); HTTP Backdoor If the returned ‘address family’ for the resolved domain name is NetBios , as specified in the lookup table above, the malware will initialise its HttpHelper class, which implements an HTTP backdoor. The backdoor commands are covered in the FireEye write-up, so let’s check only a couple of commands to see what output they produce. One of the backdoor commands is CollectSystemDescription . As its name suggests, it collects system information. By running the code reconstructed from the malware, here is an actual example of the data collected by the backdoor and delivered to the attacker’s C2 with a separate backdoor command UploadSystemDescription : 1. %DOMAIN_NAME% 2. S-1-5-21-298510922-2159258926-905146427 3. DESKTOP-VL39FPO 4. UserName 5. [E] Microsoft Windows NT 6.2.9200.0 6.2.9200.0 64 6. C:\WINDOWS\system32 7. 0 8. %PROXY_SERVER% Description: Killer Wireless-n/a/ac 1535 Wireless Network Adapter #2 MACAddress: 9C:B6:D0:F6:FF:5D DHCPEnabled: True DHCPServer: 192.168.20.1 DNSHostName: DESKTOP-VL39FPO DNSDomainSuffixSearchOrder: Home DNSServerSearchOrder: 8.8.8.8, 192.168.20.1 IPAddress: 192.168.20.30, fe80::8412:d7a8:57b9:5886 IPSubnet: 255.255.255.0, 64 DefaultIPGateway: 192.168.20.1, fe80::1af1:45ff:feec:a8eb NOTE: Field #7 specifies the number of days (0) since the last system reboot. GetProcessByDescription command will build a list of processes running on a system. This command accepts an optional argument, which is one of the custom process properties enlisted here . If the optional argument is not specified, the backdoor builds a process list that looks like: [ 1720] svchost [ 8184] chrome [ 4732] svchost If the optional argument is specified, the backdoor builds a process list that includes the specified process property in addition to parent process ID, username and domain for the process owner. For example, if the optional argument is specified as “ ExecutablePath “, the GetProcessByDescription command may return a list similar to: [ 3656] sihost.exe C:\WINDOWS\system32\sihost.exe 1720 DESKTOP-VL39FPO\UserName [ 3824] svchost.exe C:\WINDOWS\system32\svchost.exe 992 DESKTOP-VL39FPO\UserName [ 9428] chrome.exe C:\Program Files (x86)\Google\Chrome\Application\chrome.exe 4600 DESKTOP-VL39FPO\UserName Other backdoor commands enable deployment of the 2nd stage malware. For example, the WriteFile command will save the file: using (FileStream fileStream = new FileStream(path, FileMode.Append, FileAccess.Write)) { fileStream.Write(array, 0, array.Length); } The downloaded 2nd stage malware can then the executed with RunTask command: using (Process process = new Process()) { process.StartInfo = new ProcessStartInfo(fileName, arguments) { CreateNoWindow = false, UseShellExecute = false }; if (process.Start()) … Alternatively, it can be configured to be executed with the system restart, using registry manipulation commands, such as SetRegistryValue .

Tags Share this article 1/26/24 Published Protecting an organization against every conceivable threat is rarely possible. There is a practically unlimited number of potential threats in the world, and security leaders don’t have unlimited resources available to address them. Prioritizing risks associated with more severe potential impact allows leaders to optimize cybersecurity decision-making and improve the organization’s security posture. Cybersecurity risk management is important because many security measures come with large costs. Before you can implement security controls designed to protect against cyberattacks and other potential risks, you must convince key stakeholders to support the project. Having a structured approach to cyber risk management lets you demonstrate exactly how your proposed changes impact the organization’s security risk profile. This makes it much easier to calculate the return on cybersecurity investment – making it a valuable tool when communicating with board members and executives. Here are seven tips every security leader should keep in mind when creating a risk management strategy: Cultivate a security-conscious risk management culture Use risk registers to describe potential risks in detail Prioritize proactive, low-cost risk remediation when possible Treat risk management as an ongoing process Invest in penetration testing to discover new vulnerabilities Demonstrate risk tolerance by implementing the NIST Cybersecurity Framework Don’t forget to consider false positives in your risk assessment What is a Risk Management Strategy? The first step to creating a comprehensive risk management plan is defining risk. According to the International Organization for Standardization (ISO) risk is “the effect of uncertainty on objectives”. This definition is accurate, but its scope is too wide. Uncertainty is everywhere, including things like market conditions, natural disasters, or even traffic jams. As a cybersecurity leader, your risk management process is more narrowly focused on managing risks to information systems, protecting sensitive data, and preventing unauthorized access. Your risk management program should focus on identifying these risks, assessing their potential impact, and creating detailed plans for addressing them. This might include deploying tools for detecting cyberattacks, implementing policies to prevent them, or investing in incident response and remediation tools to help you recover from them after they occur. In many cases, you’ll be doing all of these things at once. Crucially, the information you uncover in your cybersecurity risk assessment will help you prioritize these initiatives and decide how much to spend on them. Your risk management framework will provide you with the insight you need to address high-risk, high-impact cybersecurity threats first and manage low-risk, low-impact threats later on. 7 Tips for Creating a Comprehensive Risk Management Strategy 1. Cultivate a security-conscious risk management culture No CISO can mitigate security risks on their own. Every employee counts on their colleagues, partners, and supervisors to keep sensitive data secure and prevent data breaches. Creating a risk management strategy is just one part of the process of developing a security-conscious culture that informs risk-based decision-making. This is important because many employees have to make decisions that impact security on a daily basis. Not all of these decisions are critical-severity security scenarios, but even small choices can influence the way the entire organization handles risk. For example, most organizations list their employees on LinkedIn. This is not a security threat on its own, but it can contribute to security risks associated with phishing attacks and social engineering . Cybercriminals may create spoof emails inviting employees to fake webinars hosted by well-known employees, and use the malicious link to infect employee devices with malware. Cultivating a risk management culture won’t stop these threats from happening, but it might motivate employees to reach out when they suspect something is wrong. This gives security teams much greater visibility into potential risks as they occur, and increases the chance you’ll detect and mitigate threats before they launch active cyberattacks. 2. Use risk registers to describe potential risks in detail A risk register is a project management tool that describes risks that could disrupt a project during execution. Project managers typically create the register during the project planning phase and then refer to it throughout execution. A risk register typically uses the following characteristics to describe individual risks: Description : A brief overview of the risk itself. Category: The formal classification of the risk and what it affects. Likelihood: How likely this risk is to take place. Analysis: What would happen if this risk occurred. Mitigation: What would the team need to do to respond in this scenario. Priority: How critical is this risk compared to others. The same logic applies to business initiatives both large and small. Using a risk register can help you identify and control unexpected occurrences that may derail the organization’s ongoing projects. If these projects are actively supervised by a project manager, risk registers should already exist for them. However, there may be many initiatives, tasks, and projects that do not have risk registers. In these cases, you may need to create them yourself. Part of the overall risk assessment process should include finding and consolidating these risk registers to get an idea of the kinds of disruptions that can take place at every level of the organization. You may find patterns in the types of security risks that you find described in multiple risk registers. This information should help you evaluate the business impact of common risks and find ways to mitigate those risks effectively. 3. Prioritize proactive, low-cost risk remediation when possible Your organization can’t afford to prevent every single risk there is. That would require an unlimited budget and on-demand access to technical specialist expertise. However, you can prevent certain high-impact risks using proactive, low-cost policies that can make a significant difference in your overall security posture. You should take these opportunities when they present themselves. Password policies are a common example. Many organizations do not have sufficiently robust password policies in place. Cybercriminals know this –that’s why dictionary-based credential attacks still occur. If employees are reusing passwords across accounts or saving them onto their devices in plaintext, it’s only a matter of time before hackers notice. At the same time, upgrading a password policy is not an especially expensive task. Even deploying an enterprise-wide password manager and investing in additional training may be several orders of magnitude cheaper than implementing a new SIEM or similarly complex security platform. Your cybersecurity risk assessment will likely uncover many opportunities like this one. Take a close look at things like password policies, change management , and security patch update procedures and look for easy, low-cost projects that can provide immediate security benefits without breaking your budget. Once you address these issues, you will be in a much better position to pursue larger, more elaborate security implementations. 4. Treat risk management as an ongoing process Every year, cybercriminals leverage new tactics and techniques against their victims. Your organization’s security team must be ready to address the risks of emerging malware, AI-enhanced phishing messages, elaborate supply chain attacks, and more. As hackers improve their attack methodologies, your organization’s risk profile shifts. As the level of risk changes, your approach to information security must change as well. This means developing standards and controls that adjust according to your organization’s actual information security risk environment. Risk analysis should not be a one-time event, but a continuous one that delivers timely results about where your organization is today – and where it may be in the future. For example, many security teams treat firewall configuration and management as a one-time process. This leaves them vulnerable to emerging threats that they may not have known about during the initial deployment. Part of your risk management strategy should include verifying existing security solutions and protecting them from new and emerging risks. 5. Invest in penetration testing to discover new vulnerabilities There is more to discovering new risks than mapping your organization’s assets to known vulnerabilities and historical data breaches. You may be vulnerable to zero-day exploits and other weaknesses that won’t be immediately apparent. Penetration testing will help you discover and assess risks that you can’t find out about otherwise. Penetration testing mitigates risk by pinpointing vulnerabilities in your environment and showing how hackers could exploit them. Your penetration testing team will provide a comprehensive report showing you what assets were compromised and how. You can then use this information to close those security gaps and build a stronger security posture as a result. There are multiple kinds of penetration testing. Depending on your specific scenario and environment, you may invest in: External network penetration testing focuses on the defenses your organization deploys on internet-facing assets and equipment. The security of any business application exposed to the public may be assessed through this kind of test. Internal network penetration testing determines how cybercriminals may impact the organization after they gain access to your system and begin moving laterally through it. This also applies to malicious insiders and compromised credential attacks. Social engineering testing looks specifically at how employees respond to attackers impersonating customers, third-party vendors, and internal authority figures. This will help you identify risks associated with employee security training . Web application testing focuses on your organization’s web-hosted applications. This can provide deep insight into how secure your web applications are, and whether they can be leveraged to leak sensitive information. 6. Demonstrate risk tolerance by implementing the NIST Cybersecurity Framework The National Institute of Standards and Technology publishes one of the industry’s most important compliance frameworks for cybersecurity risk mitigation. Unlike similar frameworks like PCI DSS and GDPR, the NIST Cybersecurity Framework is voluntary – you are free to choose when and how you implement its controls in your organization. This set of security controls includes a comprehensive, flexible approach to risk management. It integrates risk management techniques across multiple disciplines and combines them into an effective set of standards any organization can follow. As of 2023, the NIST Risk Management Framework focuses on seven steps: Prepare the organization to change the way it secures its information technology solutions. Categorize each system and the type of information it processes according to a risk and impact analysis/ Select which NIST SP 800-53 controls offer the best data protection for the environment. Implement controls and document their deployment. Assess whether the correct controls are in place and operating as intended. Authorize the implementation in partnership with executives, stakeholders, and IT decision-makers. Monitor control implementations and IT systems to assess their effectiveness and discover emerging risks. 7. Don’t forget to consider false positives in your risk assessment False positives refer to vulnerabilities and activity alerts that have been incorrectly flagged. They can take many forms during the cybersecurity risk assessment process – from vulnerabilities that don’t apply to your organization’s actual tech stack to legitimate traffic getting blocked by firewalls. False positives can impact risk assessments in many ways. The most obvious problem they present is skewing your assessment results. This may lead to you prioritizing security controls against threats that aren’t there. If these controls are expensive or time-consuming to deploy, you may end up having an uncomfortable conversation with key stakeholders and decision-makers later on. However, false positives are also a source of security risks. This is especially true with automated systems like next-generation firewalls , extended detection and response (XDR) solutions, and Security Orchestration, Automation, and Response (SOAR) platforms. Imagine one of these systems detects an outgoing video call from your organization. It flags the connection as suspicious and begins investigating it. It discovers the call is being made from an unusual location and contains confidential data, so it blocks the call and terminates the connection. This could be a case of data exfiltration, or it could be the company CEO presenting a report to stockholders while traveling. Most risk assessments don’t explore the potential risk of blocking high-level executive communications or other legitimate communications due to false positives. Use AlgoSec to Identify and Assess Network Security Risks More Accurately Building a comprehensive risk management strategy is not an easy task. It involves carefully observing the way your organization does business and predicting how cybercriminals may exploit those processes. It demands familiarity with almost every task, process, and technology the organization uses, and the ability to simulate attack scenarios from multiple different angles. There is no need to accomplish these steps manually. Risk management platforms like AlgoSec’s Horizon Security Analyzer can help you map business applications throughout your network and explore attack simulations with detailed “what-if” scenarios. Use Horizon Security Analyzer to gain deep insight into how your organization would actually respond to security incidents and unpredictable events, then use those insights to generate a more complete risk management approach.
