Tags Share this article 7/15/14 Published Insecure Service Protocols and Ports Okay, we all have them… they’re everyone’s dirty little network security secrets that we try not to talk about. They’re the protocols that we don’t mention in a security audit or to other people in the industry for fear that we’ll be publicly embarrassed. Yes, I’m talking about cleartext protocols which are running rampant across many networks. They’re in place because they work, and they work well, so no one has had a reason to upgrade them. Why upgrade something if it’s working right? Wrong. These protocols need to go the way of records, 8-tracks and cassettes (many of these protocols were fittingly developed during the same era). You’re putting your business and data at serious risk by running these insecure protocols. There are many insecure protocols that are exposing your data in cleartext, but let’s focus on the three most widely used ones: FTP, Telnet and SNMP. FTP (File Transfer Protocol) This is by far the most popular of the insecure protocols in use today. It’s the king of all cleartext protocols and one that needs to be smitten from your network before it’s too late. The problem with FTP is that all authentication is done in cleartext which leaves little room for the security of your data. To put things into perspective, FTP was first released in 1971, almost 45 years ago. In 1971 the price of gas was 40 cents a gallon, Disneyland had just opened and a company called FedEx was established. People, this was a long time ago. You need to migrate from FTP and start using an updated and more secure method for file transfers, such as HTTPS, SFTP or FTPS. These three protocols use encryption on the wire and during authentication to secure the transfer of files and login. Telnet If FTP is the king of all insecure file transfer protocols then telnet is supreme ruler of all cleartext network terminal protocols. Just like FTP, telnet was one of the first protocols that allowed you to remotely administer equipment. It became the defacto standard until it was discovered that it passes authentication using cleartext. At this point you need to hunt down all equipment that is still running telnet and replace it with SSH, which uses encryption to protect authentication and data transfer. This shouldn’t be a huge change unless your gear cannot support SSH. Many appliances or networking gear running telnet will either need the service enabled or the OS upgraded. If both of these options are not appropriate, you need to get new equipment, case closed. I know money is an issue at times, but if you’re running a 45 year old protocol on your network with the inability to update it, you need to rethink your priorities. The last thing you want is an attacker gaining control of your network via telnet. Its game over at this point. SNMP (Simple Network Management Protocol) This is one of those sneaky protocols that you don’t think is going to rear its ugly head and bite you, but it can! escortdate escorts . There are multiple versions of SNMP, and you need to be particularly careful with versions 1 and 2. For those not familiar with SNMP, it’s a protocol that enables the management and monitoring of remote systems. Once again, the strings can be sent via cleartext, and if you have access to these credentials you can connect to the system and start gaining a foothold on the network, including managing, applying new configurations or gaining in-depth monitoring details of the network. In short, it a great help for attackers if they can get hold of these credentials. Luckily version 3.0 of SNMP has enhanced security that protects you from these types of attacks. So you must review your network and make sure that SNMP v1 and v2 are not being used. These are just three of the more popular but insecure protocols that are still in heavy use across many networks today. By performing an audit of your firewalls and systems to identify these protocols, preferably using an automated tool such as AlgoSec Firewall Analyzer , you should be able to pretty quickly create a list of these protocols in use across your network. It’s also important to proactively analyze every change to your firewall policy (again preferably with an automated tool for security change management ) to make sure no one introduces insecure protocol access without proper visibility and approval. Finally, don’t feel bad telling a vendor or client that you won’t send data using these protocols. If they’re making you use them, there’s a good chance that there are other security issues going on in their network that you should be concerned about. It’s time to get rid of these protocols. They’ve had their usefulness, but the time has come for them to be sunset for good.

Cloud Security Cloud Security Checklist: Key Steps and Best Practices 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 7/21/23 Published A Comprehensive Cloud Security Checklist for Your Cloud Environment There’s a lot to consider when securing your cloud environment. Threats range from malware to malicious attacks, and everything in between. With so many threats, a checklist of cloud security best practices will save you time. First we’ll get a grounding in the top cloud security risks and some key considerations. The Top 5 Security Risks in Cloud Computing Understanding the risks involved in cloud computing is a key first step. The top 5 security risks in cloud computing are: 1. Limited visibility Less visibility means less control. Less control could lead to unauthorized practices going unnoticed. 2. Malware Malware is malicious software, including viruses, ransomware, spyware, and others. 3. Data breaches Breaches can lead to financial losses due to regulatory fines and compensation. They may also cause reputational damage. 4. Data loss The consequences of data loss can be severe, especially it includes customer information. 5. Inadequate cloud security controls If cloud security measures aren’t comprehensive, they can leave you vulnerable to cyberattacks. Key Cloud Security Checklist Considerations 1. Managing User Access and Privileges Properly managing user access and privileges is a critical aspect of cloud infrastructure. Strong access controls mean only the right people can access sensitive data. 2. Preventing Unauthorized Access Implementing stringent security measures, such as firewalls, helps fortify your environment. 3. Encrypting Cloud-Based Data Assets Encryption ensures that data is unreadable to unauthorized parties. 4. Ensuring Compliance Compliance with industry regulations and data protection standards is crucial. 5. Preventing Data Loss Regularly backing up your data helps reduce the impact of unforeseen incidents. 6. Monitoring for Attacks Security monitoring tools can proactively identify suspicious activities, and respond quickly. Cloud Security Checklist Understand cloud security risks Establish a shared responsibility agreement with your cloud services provider (CSP) Establish cloud data protection policies Set identity and access management rules Set data-sharing restrictions Encrypt sensitive data Employ a comprehensive data backup and recovery plan Use malware protection Create an update and patching schedule Regularly assess cloud security Set up security monitoring and logging Adjust cloud security policies as new issues emerge Let’s take a look at these in more detail. 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. Ensure the software you select can protect against a wide range of malware. 8b. Regularly Update Malware Definitions Anti-malware relies on malware definitions. However, cybercriminals continuously create new malware variants, so these definitions become outdated quickly. Ensure your software is set to automatically update. 8c. Conduct Regular Malware Scans Schedule regular malware scans to identify and mitigate threats promptly. This includes full system scans and real-time scanning. 8d. Implement a Malware Response Plan Develop a comprehensive malware response plan to ensure you can address any threats. Train your staff on this plan to respond efficiently during a malware attack. 8e. Monitor for Anomalous Activity Continuously monitor your systems for any anomalous activity. Early detection can significantly reduce the potential damage caused by malware. 9. Create an Update and Patching Schedule 9a. Develop a Regular Patching Schedule Develop a consistent schedule for applying patches and updates to your cloud applications. For high-risk vulnerabilities, consider implementing patches as soon as they become available. 9b. Maintain an Inventory of Software and Systems You need an accurate inventory of all software and systems to manage updates and patches. This inventory should include the system version, last update, and any known vulnerabilities. 9c. Automation Where Possible Automating the patching process can help ensure that updates are applied consistently. Many cloud service providers offer tools or services that can automate patch management. 9d. Test Patches Before Deployment Test updates in a controlled environment to ensure work as intended. This is especially important for patches to critical systems. 9e. Stay Informed About New Vulnerabilities and Patches Keep abreast of new vulnerabilities and patches related to your software and systems. Being aware of the latest threats and solutions can help you respond faster. 9f. Update Security Tools and Configurations Don’t forget to update your cloud security tools and configurations regularly. As your cloud environment evolves, your security needs may change. 10. Regularly Assess Cloud Security 10a. Set up cloud security assessments and audits Establish a consistent schedule for conducting cybersecurity assessments and security audits. Audits are necessary to confirm that your security responsibilities align with your policies. These should examine configurations, security controls, data protection and incident response plans. 10b. Conduct Penetration Testing Penetration testing is a proactive approach to identifying vulnerabilities in your cloud environment. These are designed to uncover potential weaknesses before malicious actors do. 10c. Perform Risk Assessments These assessments should cover a variety of technical, procedural, and human risks. Use risk assessment results to prioritize your security efforts. 10d. Address Assessment Findings After conducting an assessment or audit, review the findings and take appropriate action. It’s essential to communicate any changes effectively to all relevant personnel. 10f. Maintain Documentation Keep thorough documentation of each assessment or audit. Include the scope, process, findings, and actions taken in response. 11. Set Up Security Monitoring and Logging 11a. Intrusion Detection Establish intrusion detection systems (IDS) to monitor your cloud environment. IDSs operate by recognizing patterns or anomalies that could indicate unauthorized intrusions. 11b. Network Firewall Firewalls are key components of network security. They serve as a barrier between secure internal network traffic and external networks. 11c. Security Logging Implement extensive security logging across your cloud environment. Logs record the events that occur within your systems. 11d. Automate Security Alerts Consider automating security alerts based on triggering events or anomalies in your logs. Automated alerts can ensure that your security team responds promptly. 11e. Implement Information Security and Event Management (SIEM) System A Security Information and Event Management (SIEM) system can your cloud data. It can help identify patterns, security breaches, and generate alerts. It will give a holistic view of your security posture. 11f. Regular Review and Maintenance Regularly review your monitoring and logging practices to ensure they remain effective. as your cloud environment and the threat landscape evolve. 12. Adjust Cloud Security Policies as New Issues Emerge 12a. Regular Policy Reviews Establish a schedule for regular review of your cloud security policies. Regular inspections allow for timely updates to keep your policies effective and relevant. 12b. Reactive Policy Adjustments In response to emerging threats or incidents, it may be necessary to adjust on an as-needed basis. Reactive adjustments can help you respond to changes in the risk environment. 12c. Proactive Policy Adjustments Proactive policy adjustments involve anticipating future changes and modifying your policies accordingly. 12d. Stakeholder Engagement Engage relevant stakeholders in the policy review and adjustment process. This can include IT staff, security personnel, management, and even end-users. Different perspectives can provide valuable insights. 12e. Training and Communication It’s essential to communicate changes whenever you adjust your cloud security policies. Provide training if necessary to ensure everyone understands the updated policies. 12f. Documentation and Compliance Document any policy adjustments and ensure they are in line with regulatory requirements.

Micro-segmentation Why Microsegmentation is Still a Go-To Network Security Strategy Prof. Avishai Wool 2 min read Prof. Avishai Wool Short bio about author here Lorem ipsum dolor sit amet consectetur.

Tags Share this article 5/3/22 Published Prof. Avishai Wool, AlgoSec co-founder and CTO, breaks down the truths and myths about micro-segmentation and how organizations can better secure their network before their next cyberattack Network segmentation isn’t a new concept. For years it’s been the go-to recommendation for CISOs and other security leaders as a means of securing expansive networks and breaking large attack surface areas down into more manageable chunks. Just as we separate areas of a ship with secure doors to prevent flooding in the event of a hull breach, network segmentation allows us to seal off areas of our network to prevent breaches such as ransomware attacks, which tend to self-propagate and spread laterally from machine to machine. Network segmentation tends to work best in controlling north-south traffic in an organization. Its main purpose is to segregate and protect key company data and limit lateral movement by attackers across the network. Micro-segmentation takes this one step further and offers more granular control to help contain lateral east-west movement. It is a technique designed to create secure zones in networks, allowing companies to isolate workloads from one another and introduce tight controls over internal access to sensitive data. Put simply, if network segmentation makes up the floors, ceilings and protective outer hull, micro-segmentation makes up the steel doors and corridors that allow or restrict access to individual areas of the ship. Both methods can be used in combination to fortify cybersecurity posture and reduce risk vulnerability across the security network. How does micro-segmentation help defend against ransomware? The number of ransomware attacks on corporate networks seems to reach record levels with each passing year. Ransomware has become so appealing to cybercriminals that it’s given way to a whole Ransomware-as-a-Service (RaaS) sub-industry, plying would-be attackers with the tools to orchestrate their own attacks. When deploying micro-segmentation across your security network, you can contain ransomware at the onset of an attack. When a breach occurs and malware takes over a machine on a given network, the policy embedded in the micro-segmented network should block the malware’s ability to propagate to an adjacent micro-segment, which in turn can protect businesses from a system-wide shutdown and save them a great financial loss. What does Zero Trust have to do with micro-segmentation? Zero trust is a manifestation of the principle of “least privilege” security credentialing. It is a mindset that guides security teams to not assume that people, or machines, are to be trusted by default. From a network perspective, zero-trust implies that “internal” networks should not be assumed to be more trustworthy than “external” networks – quotation marks are intentional. Therefore, micro-segmentation is the way to achieve zero trust at the network level: by deploying restrictive filtering policy inside the internal network to control east-west traffic. Just as individuals in an organization should only be granted access to data on a need-to-know basis, traffic should only be allowed to travel from one area of the business to another only if the supporting applications require access to those areas. Can a business using a public cloud solution still use micro-segmentation? Prior to the advent of micro-segmentation, it was very difficult to segment networks into zones and sub-zones because it required the physical deployment of equipment. Routing had to be changed, firewalls had to be locally installed, and the segmentation process would have to be carefully monitored and managed by a team of individuals. Fortunately for SecOps teams, this is no longer the case, thanks to the rapid adoption of cloud technology. There seems to be a misconception associated with micro-segmentation where it might be thought of as a strictly private cloud environment network security solution, whereas in reality, micro-segmentation can be deployed in a hybrid cloud environment – public cloud, private cloud and on-premise. In fact, all public cloud networks, including those offered by the likes of Azure and AWS, offer “baked in” filtering capabilities that make controlling traffic much easier. This lends itself well to the concept of micro-segmentation, so even those businesses that use a hybrid cloud setup can still benefit enormously. The Bottom Line Micro-segmentation presents a viable and scalable solution to tighten network security policies, despite its inherent implementation challenges. While many businesses may find it hard to manage this new method of security, it’s nevertheless a worthwhile endeavor. By utilizing a micro-segmentation method as part of its network security strategy, an organization can immediately bolster its network security against possible hackers and potential data breaches.

Auditing and Compliance Compliance Made Easy: How to improve your risk posture with automated audits Tal Dayan 2 min read Tal Dayan 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 4/29/21 Published Tal Dayan, security expert for AlgoSec, discusses the secret to passing audits seamlessly and how to introduce automated compliance Compliance standards come in many different shapes and sizes. Some organizations set their own internal policies, while others are subject to regimented global frameworks such as PCI DSS , which protects customers’ card payment details; SOX to safeguard financial information or HIPAA , which protects patients’ healthcare data. Regardless of which industry you operate in, regular auditing is key to ensuring your business retains its risk posture whilst also remaining compliant. The problem is that running manual risk and security audits can be a long, drawn-out, and tedious affair. A 2020 report from Coalfire and Omdia  found that for the majority of organizations, growing compliance obligations are now consuming 40% or more of IT security budgets and threaten to become an unsustainable cost.  The report suggests two reasons for this growing compliance burden.  First, compliance standards are changing from point-in-time reviews to continuous, outcome-based requirements. Second, the ongoing cyber-skills shortage is stretching organizations’ abilities to keep up with compliance requirements. This means businesses tend to leave them until the last moment, leading to a rushed audit that isn’t as thorough as it could be, putting your business at increased risk of a penalty fine or, worse, a data breach that could jeopardize the entire organization. The auditing process itself consists of a set of requirements that must be created for organizations to measure themselves against. Each rule must be manually analyzed and simulated before it can be implemented and used in the real world. As if that wasn’t time-consuming enough, every single edit to a rule must also be logged meticulously. That is why automation plays a key role in the auditing process. By striking the right balance between automated and manual processes, your business can achieve continuous compliance and produce audit reports seamlessly. Here is a six-step strategy that can set your business on the path to sustainable and successful ongoing auditing preservation: Step 1: Gather information This step will be the most arduous but once completed it will become much easier to sustain. This is when you’ll need to gather things like security policies, firewall access logs, documents from previous audits and firewall vendor information – effectively everything you’d normally factor into a manual security audit. Step 2: Define a clear change management process A good change management process is essential to ensure traceability and accountability when it comes to firewall changes. This process should confirm that every change is properly authorized and logged as and when it occurs, providing a picture of historical changes and approvals. Step 3: Audit physical & OS security With the pandemic causing a surge in the number of remote workers and devices used, businesses must take extra care to certify that every endpoint is secured and up-to-date with relevant security patches. Crucially, firewall and management services should also be physically protected, with only designated personnel permitted to access them. Step 4: Clean up & organize rule base As with every process, the tidier it is, the more efficient it is. Document rules and naming conventions should be enforced to ensure the rule base is as organized as possible, with identical rules consolidated to keep things concise. Step 5: Assess & remediate risk Now it’s time to assess each rule and identify those that are particularly risky and prioritize them by severity. Are there any that violate corporate security policies? Do some have “ANY” and a permissive action? Make a list of these rules and analyze them to prepare plans for remediation and compliance. Step 6: Continuity & optimization Now it’s time to simply hone the first five steps and make these processes as regular and streamlined as possible. By following the above steps and building out your own process, you can make day-to-day compliance and auditing much more manageable. Not only will you improve your compliance score, you’ll also be able to maintain a sustainable level of compliance without the usual disruption and hard labor caused by cumbersome and expensive manual processes.

Hybrid Cloud Security Management Six best practices for managing security in the hybrid cloud Omer Ganot 2 min read Omer Ganot 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 8/5/21 Published Omer Ganot, Cloud Security Product Manager at AlgoSec, outlines six key things that businesses should be doing to ensure their security in a hybrid cloud environment Over the course of the past decade, we’ve seen cloud computing vastly transitioning from on-prem to the public cloud. Businesses know the value of the cloud all too well, and most of them are migrating their operations to the cloud as quickly as possible, particularly considering the pandemic and the push to remote working. However, there are major challenges associated with transitioning to the cloud, including the diversity and breadth of network and security controls and a dependency on legacy systems that can be difficult to shake. Public cloud allows organizations for better business continuity, easier scalability and paves the way for DevOps to provision resources and deploy projects quickly. But, what’s the security cost when looking at the full Gpicture of the entire hybrid network? Here I outline the six best practices for managing security in the hybrid cloud: 1. Use next-generation firewalls Did you know that almost half (49%) of businesses report running virtual editions of traditional firewalls in the cloud? It’s becoming increasingly clear that cloud providers’ native security controls are not enough, and that next-gen firewall solutions are needed. While a traditional stateful firewall is designed to monitor incoming and outgoing network traffic, a next-generation firewall (NGFW) includes features such as application awareness and control, integrated breach prevention and active threat intelligence. In other words, while a traditional firewall will allow for layer 1-2 protection, NGFWs allow for protection from levels 3 through 7. 2. Use dynamic objects On-premise security tends to be easier because subnets and IP addresses are typically static. In the cloud, however, workloads are dynamically provisioned and decommissioned, IP addresses change, so traditional firewalls simply cannot keep up. NGFW dynamic objects allow businesses to match a group of workloads using cloud-native categories, and then use these objects in policies to properly enforce traffic and avoid the need to frequently update the policies. 3. Gain 360-degree visibility As with any form of security, visibility is critical. Without that, even the best preventative or remedial strategies will fall flat. Security should be evaluated both in your cloud services and in the path from the internet and data center clients. Having one single view over the entire network estate is invaluable when it comes to hybrid cloud security. AlgoSec’s powerful AutoDiscovery capabilities help you understand the network flows in your organization. You can automatically connect the recognized traffic flows to the business applications that use them and seamlessly manage the network security policy across your entire hybrid estate. 4. Evaluate risk in its entirety Too many businesses are guilty of only focusing on cloud services when it comes to managing security. This leaves them inherently vulnerable on other network paths, such as the ones that run from the internet and data centers towards the services in the cloud. As well as gaining 360-degree visibility over the entire network estate, businesses also need to be sure to actively monitor those areas for risk with equal weighting in terms of priority. 5. Clean up cloud policies regularly The cloud security landscape changes at a faster rate than most businesses can realistically keep up with. For that reason, cloud security groups tend to change with the wind, constantly being adjusted to account for new applications. If a business doesn’t keep on top of its cloud policy ‘housekeeping’, they’ll soon become bloated, difficult to maintain and risky. Keep cloud security groups clean and tidy so they’re accurate, efficient and don’t expose risk. 6. Embrace DevSecOps The cloud might be perfect for DevOps in terms of easy and agile resource and security provisioning using Infrastructure-as-code tools, but the methodology is seldom used for risk analysis and remediation recommendations. Businesses that want to take control of their cloud security should pay close attention to this. Before a new risk is introduced, you should obtain an automatic what-if risk check as part of the code’s pull request, before pushing to production. From visibility and network management right through to risk evaluation and clean-up, staying secure in a hybrid cloud environment might sound like hard work, but by embracing these fundamental practices your organization can start putting together the pieces of its own security puzzle. The AlgoSec Security Management Suite (ASMS) makes it easy to support your cloud migration journey, ensuring that it does not block critical business services and meet compliance requirements.

Tags Share this article 8/10/23 Published Problems with firewalls can be quite disastrous to your operations. When firewall rules are not set properly, you might deny all requests, even valid ones, or allow access to unauthorized sources. There needs to be a systematic way to troubleshoot your firewall issues, and you need to have a proper plan. You should consider security standards, hardware/software compatibility, security policy planning , and access level specifications. It is recommended to have an ACL (access control list) to determine who has access to what. Let us give you a brief overview of firewall troubleshooting best practices and steps to follow. Common firewall problems With the many benefits that firewalls bring, they might also pop out some errors and issues now and then. You need to be aware of the common issues, failures, and error codes to properly assess an error condition to ensure the smooth working of your firewalls. Misconfiguration errors A report by Gartner Research says that misconfiguration causes about 95% of all firewall breaches. A simple logical flaw in a firewall rule can open up vulnerabilities, leading to serious security breaches. Before playing with your firewall settings, you must set up proper access control settings and understand the security policy specifications. You must remember that misconfiguration errors in CLI can lead to hefty fines for non-compliance, data breaches , and unnecessary downtimes. All these can cause heavy monetary damages; hence, you should take extra care to configure your firewall rules and settings properly. Here are some common firewall misconfigurations: Allowing ICMP and making the firewall available for ping requests Providing unnecessary services on the firewall Allowing unused TCP/UDP ports The firewall is set to return a ‘deny’ response instead of a ‘drop’ for blocked ports. IP address misconfigurations that can allow TCP pinging of internal hosts from external devices. Trusting DNS and IP addresses that are not properly checked and source verified. Check out AlgoSec’s firewall configuration guide for best practices. Hardware issues Hardware bottlenecks and device misconfigurations can easily lead to firewall failures. Sometimes, running a firewall 24/7 can overload your hardware and lead to a lowered network performance of your entire system. You should look into the performance issues and optimize firewall functionalities or upgrade your hardware accordingly. Software vulnerabilities Any known vulnerability with your firewall software must be dealt with immediately. Hackers can exploit software vulnerabilities easily to gain backdoor entry into your network. So, stay current with all the patches and updates your software vendors provide. Types of firewall issues Most firewall issues can be classified as either connectivity or performance issues. Here are some tools you can use in each of these cases: Connectivity Issues Some loss of access to a network resource or unavailability usually characterizes these issues. You can use network connectivity tools like NetStat to monitor and analyze the inbound TCP/UDP packets. Both these tools have a wide range of sub-commands and tools that help you trace IP network traffic and control the traffic as per your requirements. Firewall Performance Issues As discussed earlier, performance issues can cause a wide range of issues, such as unplanned downtimes and firewall failures, leading to security breaches and slow network performance. Some of the ways you can rectify it include: Load balancing by regulating the outbound network traffic by limiting the internal server errors and streamlining the network traffic. Filtering the incoming network traffic with the help of Standard Access Control List filters. Simplifying firewall rules to reduce the load on the firewall applications. You can remove unused rules and break down complex rules to improve performance. Firewall troubleshooting checklist steps Step 1. Audit your hardware & software Create a firewall troubleshooting checklist to check your firewall rules, software vulnerabilities, hardware settings, and more based on your operating system. This should include all the items you should cover as part of your security policy and network assessment. With Algosec’s policy management , you can ensure that your security policy is complete, comprehensive and does not miss out on anything important. Step 2. Pinpoint the Issue Check what the exact issue is. Generally, a firewall issue can arise from any of the three conditions: Access from external networks/devices to protected resources is not functioning properly Access from the protected network/resources to unprotected resources is not functioning properly. Access to the firewall is not functioning properly. Step 3. Determine the traffic flow Once you have ascertained the exact access issue, you should check whether the issue is raised when traffic is going to the firewall or through the firewall. Once you have narrowed down this issue, you can test the connectivity accordingly and determine the underlying cause. Check for any recent updates and try to roll back if that can solve the issue. Go through your firewall permissions and logs for any error messages or warnings. Review your firewall rules and configurations and adjust them for proper working. Depending upon your firewall installation, you can make a checklist of items. Here is a simple guide you can follow to conduct routine maintenance troubleshooting . Monitor the network, test it out, and repeat the process until you reach a solution. Firewall troubleshooting best practices Here are some proven firewall troubleshooting tips. For more in-depth information, check out our Network Security FAQs page. Monitor and test Regular auditing and testing of your Microsoft firewall can help you catch vulnerabilities early and ensure good performance throughout the year. You can use expert-assisted penetration testing to get a good idea of the efficacy of your firewalls. Also be sure to check out the auditing services from Algosec , especially for your PCI security compliance . Deal with insider threats While a Mac or Windows firewall can help you block external threats to an extent, it can be powerless regarding insider attacks. Make sure you enforce strong security controls to avoid any such conditions. Your security policies must be crafted well to avoid any room for such conditions, and your access level specifications should also be well-defined. Device connections Make sure to pay attention to the other modes of attack that can happen besides a network access attempt. If an infected device such as a USB, router, hard drive, or laptop is directly connected to your system, your network firewall can do little to prevent the attack. So, you should put the necessary device restrictions in your privacy statement and the firewall rules. Review and Improve Update your firewall rules and security policies with regular audits and tests. Here are some more tips you can follow to improve your firewall security: Optimize your firewall ruleset to allow only necessary access Use unique user IP instead of a root ID to launch the firewall services Make use of a protected remote Syslog server and keep it safe from unauthorized access Analyze your firewall logs regularly to identify and detect any suspicious activity. You can use tools like Algosec Firewall Analyzer and expert help to analyze your firewall as well. Disable FTP connections by default Setup strict controls on how and which users can modify firewall configurations. Include both source and destination IP addresses and the ports in your firewall rules. Document all the updates and changes made to your firewall policies and rules. In the case of physical firewall implementations, restrict the physical access as well. Use NAT (network address translation) to map multiple private addresses to a public IP address before transmitting the information online. How does a firewall actually work? A Windows firewall is a network security mechanism that allows you to restrict incoming network traffic to your systems. It can be implemented as a hardware, software, or cloud-based security solution . It acts as a barrier stopping unauthorized network access requests from reaching your internal network and thus minimizing any attempt at hacking or breach of confidential data . Based on the type of implementation and the systems it is protecting, firewalls can be classified into several different types. Some of the common types of firewalls are: Packet filtering – Based on the filter standards, a small amount of incoming data is analyzed and subjected to restriction on distribution across the network. Proxy service – An application layer service that acts as an intermediary between the actual servers to block out unauthorized access requests. Stateful inspection – A dynamic packet filtering mechanism that filters out the network packets. Next-Generation Firewall (NGFW) – A combination of deep packet inspection and application level inspection to block out unauthorized access into the network. Firewalls are essential to network security at all endpoints, whether personal computers or full-scale enterprise data centers. They allow you to set up strong security controls to prevent a wide range of cyberattacks and help you gain valuable data. Firewalls can help you detect suspicious activities and prevent intrusive attacks at the earliest. They can also help you regulate your incoming and outgoing traffic routing, helping you implement zero-trust security policies and stay compliant with security and data standards.

Before I became a Sale Engineer I started my career working in operations and I don’t remember the first time I heard the term zero trust... Zero Trust AlgoSec and Zero-Trust for Healthcare Adolfo Lopez 2 min read Adolfo Lopez 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 2/26/24 Published Before I became a Sale Engineer I started my career working in operations and I don’t remember the first time I heard the term zero trust but I all I knew is that it was very important and everyone was striving to get to that level of security. Today I’ll get into how AlgoSec can help achieve those goals, but first let’s have a quick recap on what zero trust is in the first place. There are countless whitepapers and frameworks that define zero trust much better than I can, but they are also multiple pages long, so I’ll do a quick recap. Traditionally when designing a network you may have different zones and each zone might have different levels of access. In many of these types of designs there is a lot of trust that is given once they are in a certain zone. For example, once someone gets to their workplace at the hospital, the nursing home, the dental center or any other medical office and does all the necessary authentication steps (proper company laptop, credentials, etc…) they potentially have free reign to everything. This is a very simple example and in a real-world scenario there would hopefully be many more safeguards in place. But what does happen in real world scenarios is that devices still manage to get trusted more than they should. And from my own experience and from working with customers this happens way too often. Especially in the healthcare industry this is becoming more and more important. These days there are many different types of medical devices, some that hold sensitive information, some scanning instruments, and some that might even be critical to patient support. More importantly many are connected to some type of network. Because of this level of connectivity, we do need to start shifting toward this idea of zero trust. In healthcare cybersecurity isn’t just a matter of maintaining the network, it’s about maintaining the critical operations of the hospitals running smoothly and patient data safe and secure. Maintaining security policies is critical to achieving zero trust. Below you can see some of the key features that AlgoSec has that can help achieve that goal. Feature Description Security Policy Analysis Analyze existing security policy sets across all parts of the network (on-premises and cloud) with various vendors. Policy Cleanup Identify and remove redundant rules, duplicate rules, and more from the first report. Specific Recommendations Over time, recommendations become more specific, such as identifying unnecessary rules (e.g., a printer talking to a medical device without actual use). Application Perspective Tie firewall rules to actual applications to understand the business function they support, leading to more targeted security policies. Granularity & Visibility Higher level of visibility and granularity in security policies, focusing on specific application flows rather than broad network access. Security Posture by Application View and assess security risks and vulnerabilities at the application level, improving overall security posture. One of my favorite aspects of the AlgoSec platform is that we not only help optimize your security policies, but we also start to look at security from an application perspective. Traditionally, firewall change requests come in and it’s just asking for very specific things, “Source A to Destination B using Protocol C.” But using AlgoSec we tie those rules to actual applications to see what business function this is supporting. By knowing the specific flows and tying them to a specific application this allows us to keep a closer eye on the actual security policies we need to create. This helps with that zero trust journey because having that higher level of visibility and granularity helps to keep the rules more specific. Instead of a change request coming in that is allowing wide open access between two subnets the application can be designed for only the access that is required. It also allows for an overall better view of the security posture. Zero trust, like many other ideas and frameworks in our industry might seem farfetched at first. We ask ourselves, how do we get there or how do we implement without it becoming so cumbersome that we give up on it. I think it’s normal to be a bit pessimistic about achieving the goal and it’s completely fine to look at some projects as moving targets that we might not have a hard deadline on. There usually isn’t a magic bullet that accomplish our goals, especially something like achieving zero trust. Multiple initiatives and projects are necessary. With AlgoSec’s expertise in application connectivity and policy management, we can be a key partner in that journey.

Security Policy Management Deploying NSPM to Implement a Gartner Analyst’s Work from Home Network Security Advice Jeffrey Starr 2 min read Jeffrey Starr 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 4/27/20 Published Recommendations from Rajpreet Kaur, Senior Principal Analyst at Gartner, in her recent blog on remote working, and a perspective on how Network Security Policy Management systems can help enterprises act upon this guidance The COVID-19 pandemic has been the catalyst for a global migration to remote home working. Managing and mitigating the network security risks this presents, on such an unprecedented scale and for a long period of time, poses a significant challenge even for companies that had remote access working plans in place before the pandemic. Not only are cybercriminals taking advantage of network insecurities to leverage attacks, they are also exploiting human anxiety around the crisis to break through security barriers. In fact, a recent survey found that 40 percent of companies reported seeing increased cyberattacks as they enable remote working. So how should organizations manage their security during these massive changes in network usage? In a recent blog , Rajpreet Kaur , Gartner Senior Principal Analyst, and a specialized expert on both hybrid environment network security and NSPM tools, offered recommendations to organizations on how to handle remote infrastructure security challenges, many of which closely align with a focus on network policy automation and application security. Here’s how network security policy management systems can support and enable Rajpreet Kaur’s key recommendations. 1. Don’t panic and start moving things to the cloud without a proper architectural design in place. Panicking and starting a large-scale move to the cloud without a proper plan in place can lead to poor security controls and ill-prepared migration. Before moving to the cloud, organizations must consider their network’s architectural design, which should always start with analysis. The analytical and discovery capabilities of NSPM systems automate this process by discovering and mapping network connectivity and providing a network map, which helps you to understand your network components, making migrations easier, faster and glitch-free. 2. Design a proper network security architecture and plan considering limited disruption and supporting work from home. Implementing these immediate and urgent network changes can only be done effectively and securely with robust change management processes. As with network analysis, NSPM automation capabilities are also vital in rapid change management. Security automation dramatically accelerates change processes, with request generation to implementation time drastically shortened and enables better enforcement and auditing for regulatory compliance. It also helps organizations overcome skill gaps and staffing limitations, which may have already been impacted by the current crisis. NSPM solutions enable full end-to-end change analysis and automation, including what if security checks, automation design, push of changes, and full documentation and audit trail. This ensures that changes can be implemented rapidly, and applied consistently and efficiently, with a full audit trail of every change. 3. Plan for what you need now, don’t try to implement a long-term strategic solution to fix your immediate needs. The current widespread move to home working is adding an extra layer of complexity to remote network security, since organizations are finding themselves having to implement new security policies and roll out adoption in a very short timeframe. Considering this, it’s important for organizations to focus on short-term needs, rather than attempting to develop a long-term strategic solution. Trying to develop a long-term solution in such a short window can be overwhelming and increase the risk of opening security vulnerabilities. Using NSPM speeds up the configuration and implementation process, allowing you to get your remote network security firewall policies up and running as soon as possible, with minimum disruption to your remote workforce. Once you have dealt with the critical immediate needs, you can then focus on developing a more long-term strategy. 4. Try to support your existing work from home employees by doing minimal changes to the existing architecture, like meeting throughput requirements and upgrading the equipment or restricting the access to a group of employees at times. Managing application connectivity and accessibility is key to ensuring minimal work disruption as employees move to remote working. An effective NSPM solution allows you to discover, identify and map business applications to ensure that they are safe and have the necessary connectivity flows. Having such a view of all the applications that are accessing the network allows security teams to map the workflow and provides visibility of the application’s required connectivity in order to minimise outages. 5. For any new network changes and upgrades, or new deployments, consider developing a work from home first strategy. Developing a work from home (WFH) strategy has never been more essential. The challenge is that WFH is a more vulnerable environment; employees are accessing sensitive data from a range of home devices, via outside networks, that may not have the same security controls. On top of this, cyber threats have already seen a sharp increase as cybercriminals exploit the widespread anxiety and vulnerabilities caused by the global crisis. IT security and networking staff are therefore having to do more, with the same staffing levels, whilst also navigating the challenges of doing this remotely from home. NSPM capabilities can help in overcoming these WFH issues. Security teams may, for example, need to change many Firewall rules to allow secure access to sensitive data. An effective NSPM solution can facilitate this and enable fast deployment by providing the ability to make changes to applications’ firewall openings from a single management interface. 6. Enhance security around public facing applications to protect against COVID-19 related cyber-attacks. With the move to remote working, organizations are increasingly relying on applications to carry out their work from home. Ensuring that business-critical applications stay available and secure while shifting to remote work is key to avoiding workflow disruption. It’s essential to take an application centric approach to application security, and an effective NSPM solution can help you to better manage and secure your business-critical applications . As discussed above, application visibility is key here. NSPM systems provides comprehensive application visibility, security operation teams can monitor critical applications for risks and vulnerabilities to ensure that they are safe. Gartner’s Rajpreet Kaur has delivered a good combination of practical and timely guidance along with the logical insights underlying the useful recommendations. These tips bring helpful guidance on the Work from Home security challenge that stands out for its clear relevance when there is now so much other noise out there. A robust NSPM can help you rapidly implement these invaluable recommendations.

Cloud Security Securing the Future: A Candid Chat with Ava Chawla, Director of cloud security at AlgoSec Adel Osta Dadan 2 min read Adel Osta Dadan 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 6/15/24 Published In the bustling world of cloud security, where complexity and rapid change are the norms, Ava Chawla, Director of Cloud Security at AlgoSec, sits down to share her insights and experiences. With a relaxed yet passionate demeanor, Ava discusses how her team is pioneering strategies to keep businesses safe and thriving amidst the digital transformation. Embracing the “100x Revolution” “Look, the landscape has transformed dramatically,” Ava reflects with a thoughtful pause. “We’re not just talking about incremental changes here; it’s about a revolution—a ‘100x revolution.’ It’s where everything is exponentially more complex and moves at breakneck speeds. And at the heart? Applications. They’re no longer just supporting business processes; they’re driving them, creating new opportunities, modernizing how we operate, and pushing boundaries.” The Power of Double-Layered Cloud Security Leaning in, Ava shares the strategic thinking behind their innovative approach to cloud security. “One of the things we’ve pioneered is what we call application-centric double-layered cloud security. This is about proactively stopping attacks, and better managing vulnerabilities to safeguard your most critical business applications and data. Imagine a stormy day, you layer up with raincoat and warm clothes for protection The sturdy raincoat represents the network layer, shielding against initial threats, while the layers of clothing underneath symbolize the configuration layer, providing added insulation. Together, these layers offer double layer protection. For businesses, double-layer cloud security means defense in depth at the network layer, unique to AlgoSec, and continuous monitoring across everything in the cloud. Now combine double-layered security with an application centric approach focused on business continuity and data protection across the applications that run the business. Cloud configurations risks are inevitable. You are responsible for safeguarding the business. Imagine you have a tool where you start with an AI-driven view of all your business applications and the attack surface, in seconds you can spot any vulnerable paths open for exploitation as it relates to your most critical applications. Application centric double layer security – the double layers is that extra layer of protection you need when the environment is unpredictable. Combine this with an app-centric perspective for effective prioritization and better security management. It’s a powerful combination! This approach isn’t just about adding more security; it’s about smart security, designed to tackle the challenges that our IT and security teams face every day across various cloud platforms.” Making Security Predictive, Not Just Reactive Ava’s passion is evident as she discusses the proactive nature of their security measures. “We can’t just be reactive anymore,” she says, emphasizing each word. “Being predictive, anticipating what’s next, that’s where we really add value. It’s about seeing the big picture, understanding the broader implications of connectivity and security. Our tools and solutions are built to be as dynamic and forward-thinking as the businesses we protect.” Aligning Security With Business Goals “There’s a beautiful alignment that happens when security and business goals come together,” Ava explains. “It’s not just about securing things; it’s about enabling business growth, expansion, and innovation. We integrate our security strategies with business objectives to ensure that as companies scale and evolve, their security posture does too.” A Vision for the Future With a reflective tone, Ava looks ahead. “What excites me the most about the future is our commitment to innovation and staying ahead of the curve. We’re not just keeping up; we’re setting the pace. We envision a world where technology empowers, enhances, and expands human potential. That’s the future we’re building towards—a secure, thriving digital landscape.” A Closing Thought As the conversation wraps up, Ava’s enthusiasm is palpable. “Our promise at AlgoSec is simple: we empower businesses without interfering with their productivity. We turn digital challenges into growth opportunities. It’s not just about managing risks—it’s about leveraging them for growth.” In a world driven by rapid technological advancements and significant security risks, Ava Chawla and her team at AlgoSec are crafting solutions that ensure businesses can navigate the complexities of the digital landscape with confidence and creativity.

Cloud Security Prevasio’s Role in Red Team Exercises and Pen Testing 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 12/21/20 Published Cybersecurity is an ever prevalent issue. Malicious hackers are becoming more agile by using sophisticated techniques that are always evolving. This makes it a top priority for companies to stay on top of their organization’s network security to ensure that sensitive and confidential information is not leaked or exploited in any way. Let’s take a look at the Red/Blue Team concept, Pen Testing, and Prevasio’s role in ensuring your network and systems remain secure in a Docker container atmosphere. What is the Red/Blue Team Concept? The red/blue team concept is an effective technique that uses exercises and simulations to assess a company’s cybersecurity strength. The results allow organizations to identify which aspects of the network are functioning as intended and which areas are vulnerable and need improvement. The idea is that two teams (red and blue) of cybersecurity professionals face off against each other. The Red Team’s Role It is easiest to think of the red team as the offense. This group aims to infiltrate a company’s network using sophisticated real-world techniques and exploit potential vulnerabilities. It is important to note that the team comprises highly skilled ethical hackers or cybersecurity professionals. Initial access is typically gained by stealing an employee’s, department, or company-wide user credentials. From there, the red team will then work its way across systems as it increases its level of privilege in the network. The team will penetrate as much of the system as possible. It is important to note that this is just a simulation, so all actions taken are ethical and without malicious intent. The Blue Team’s Role The blue team is the defense. This team is typically made up of a group of incident response consultants or IT security professionals specially trained in preventing and stopping attacks. The goal of the blue team is to put a stop to ongoing attacks, return the network and its systems to a normal state, and prevent future attacks by fixing the identified vulnerabilities. Prevention is ideal when it comes to cybersecurity attacks. Unfortunately, that is not always possible. The next best thing is to minimize “breakout time” as much as possible. The “breakout time” is the window between when the network’s integrity is first compromised and when the attacker can begin moving through the system. Importance of Red/Blue Team Exercises Cybersecurity simulations are important for protecting organizations against a wide range of sophisticated attacks. Let’s take a look at the benefits of red/blue team exercises: Identify vulnerabilities Identify areas of improvement Learn how to detect and contain an attack Develop response techniques to handle attacks as quickly as possible Identify gaps in the existing security Strengthen security and shorten breakout time Nurture cooperation in your IT department Increase your IT team’s skills with low-risk training What are Pen Testing Teams? Many organizations do not have red/blue teams but have a Pen Testing (aka penetration testing) team instead. Pen testing teams participate in exercises where the goal is to find and exploit as many vulnerabilities as possible. The overall goal is to find the weaknesses of the system that malicious hackers could take advantage of. Companies’ best way to conduct pen tests is to use outside professionals who do not know about the network or its systems. This paints a more accurate picture of where vulnerabilities lie. What are the Types of Pen Testing? Open-box pen test – The hacker is provided with limited information about the organization. Closed-box pen test – The hacker is provided with absolutely no information about the company. Covert pen test – In this type of test, no one inside the company, except the person who hires the outside professional, knows that the test is taking place. External pen test – This method is used to test external security. Internal pen test – This method is used to test the internal network. The Prevasio Solution Prevasio’s solution is geared towards increasing the effectiveness of red teams for organizations that have taken steps to containerize their applications and now rely on docker containers to ship their applications to production. The benefits of Prevasio’s solution to red teams include: Auto penetration testing that helps teams conduct break-and-attack simulations on company applications. It can also be used as an integrated feature inside the CI/CD to provide reachability assurance. The behavior analysis will allow teams to identify unintentional internal oversights of best practices. The solution features the ability to intercept and scan encrypted HTTPS traffic. This helps teams determine if any credentials should not be transmitted. Prevasio container security solution with its cutting-edge analyzer performs both static and dynamic analysis of the containers during runtime to ensure the safest design possible. Moving Forward Cyberattacks are as real of a threat to your organization’s network and systems as physical attacks from burglars and robbers. They can have devastating consequences for your company and your brand. The bottom line is that you always have to be one step ahead of cyberattackers and ready to take action, should a breach be detected. The best way to do this is to work through real-world simulations and exercises that prepare your IT department for the worst and give them practice on how to respond. After all, it is better for your team (or a hired ethical hacker) to find a vulnerability before a real hacker does.

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.
