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.

SANOFI FINDS THE CURE FOR TIME-CONSUMING APPLICATION MIGRATION WITH ALGOSEC Organization Sanofi Industry Healthcare & Pharmaceuticals Headquarters Paris, France Download case study Share Customer
success stories "Using AlgoSec during our data center migration allowed us to give technical project leaders access to all of the rules involved in the migration of their applications, which reduced the IT security team’s time on these projects by 80%. The application was very useful, simple to use and made everybody happy." AlgoSec Business Impact Simplify data center migration projects Reduce rule migration process time by 80% Streamline and improve firewall operations Background A multinational pharmaceutical company, Sanofi, has 112 industrial sites in 41 countries and operations in more than 100 countries. The company’s 110,000 employees are committed to protecting health, enhancing life, providing hope and responding to the potential healthcare needs of seven billion people around the world. Challenge The sensitive nature of Sanofi’s business and its wide ranging global operations require an extensive and well secured network, which currently has 120 firewalls all over the world. In the midst of a data center consolidation project, the company needed to understand how its security devices would be affected by application migrations. Sanofi was also eager to improve change management processes and gain key performance indicators (KPIs) for risk analysis.“Our main concern with the data center consolidation project was to enable various technical project leaders to see the different rules impacting the migration of their applications, and to avoid any outages. For that, we needed pre-migration and post-migration documentation on security,” says Bruno Roulleau, Network Security Architect at Sanofi. “We also needed metrics on the risk associated with different policies on the firewalls.” Solution When looking for a solution, Sanofi evaluated several vendors. “A key point for us was the ability to easily integrate the security devices in our current infrastructure, into the solution. We also wanted detailed reporting that would allow us to delegate policy management to project leaders,” Roulleau notes.Because Sanofi constantly upgrades its devices, its systems need to evolve and incorporate the new devices and rules seamlessly. “We chose the AlgoSec Security Management solution because its graphical interface is very user-friendly, it easily supports new devices and generates detailed reports and metrics on risks,” says Roulleau.Sanofi also appreciated AlgoSec’s flexibility. “AlgoSec is very open to developing new capabilities. We can ask to have some new features available by a certain date and they will deliver on time,” according to Roulleau. For a company with a complex network and rapidly evolving security needs, that responsiveness proved key to the decision to go with AlgoSec. Results Sanofi’s security team is now able to delegate responsibility for rule changes both during migration and on an ongoing basis. “Using AlgoSec during our data center migration allowed us to give technical project leaders access to all of the rules involved in the migration of their applications, which reduced the IT security team’s time on these projects by 80%. The application was very useful, simple to use and made everybody happy,” Roulleau says.Additionally, with AlgoSec’s reports Sanofi can now easily and clearly document the status of their firewalls as well as the impact of any changes on the network throughout the migration project. “We can now generate detailed reports in just three clicks!” Roulleau adds.Furthermore, AlgoSec’s optimization reports enabled Sanofi to clean up its security policies. Because they could clearly see all of the rules and their impact on network security, Roulleau’s team was able to safely eliminate unused and duplicate rules, which increased the efficiency of the firewalls. Those reports also provided insight into the risks associated with the current system and various changes being made. Schedule time with one of our experts

Cloud Security Sunburst Backdoor, Part III: DGA & Security Software 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 12/22/20 Published In the previous parts of our blog ( part I and part II ), we have described the most important parts of the Sunburst backdoor functionality and its Domain Generation Algorithm (DGA). This time, let’s have a deeper look into the passive DNS requests reported by Open-Source Context and Zetalytics . The valid DNS requests generated by the malware fall into 2 groups: DNS requests that encode a local domain name DNS requests that encode data The first type of DNS requests allows splitting long domain names into separate requests. These requests are generated by the malware’s functions GetPreviousString() and GetCurrentString() . In general, the format of a DNS request that encodes a domain name may look like: USER_ID.NUM.COMPUTER_DOMAIN[.]appsync-api.us-west-2[.]avsvmcloud[.]com where: USER_ID is an 8-byte user ID that uniquely identifies a compromised host, encoded as a 15-character string NUM is a number of a domain name – either 0 or 1, encoded as a character COMPUTER_DOMAIN is an encoded local computer domain Let’s try decoding the following 3 DNS requests: olc62cocacn7u2q22v02eu.appsync-api.us-west-2.avsvmcloud.com r1qshoj05ji05ac6eoip02jovt6i2v0c.appsync-api.us-west-2.avsvmcloud.com lt5ai41qh5d53qoti3mkmc0.appsync-api.us-west-2.avsvmcloud.com String 1 Let’s start from the 1st string in the list: olc62cocacn7u2q22v02eu.appsync-api.us-west-2.avsvmcloud.com. In this string, the first 15-character string is an encoded USER_ID : “olc62cocacn7u2q” . Once it is base-64 decoded, as explained in the previous post, it becomes a 9-byte byte array: 86 7f 2f be f9 fb a3 ae c4 The first byte in this byte array is a XOR key: 0x86 . Once applied to the 8 bytes that follow it, we get the 8-byte user ID – let’s take a note and write it down, we will need it later: f9 a9 38 7f 7d 25 28 42 Next, let’s take the NUM part of the encoded domain: it’s a character “2” located at the position #15 (starting from 0) of the encrypted domain. In order to decode the NUM number, we have to take the first character of the encrypted domain, take the reminder of its division by 36 , and subtract the NUM ‘s position in the string “0123456789abcdefghijklmnopqrstuvwxyz” : num = domain[0] % 36 – “0123456789abcdefghijklmnopqrstuvwxyz”.IndexOf(domain.Substring(15, 1)); The result is 1 . That means the decrypted domain will be the 2nd part of a full domain name. The first part must have its NUM decoded as 0. The COMPUTER_DOMAIN part of the encrypted domain is “2v02eu” . Once decoded, using the previously explained method, the decoded computer domain name becomes “on.ca” . String 2 Let’s decode the second passive DNS request from our list: r1qshoj05ji05ac6eoip02jovt6i2v0c.appsync-api.us-west-2.avsvmcloud.com Just as before, the decoded 8-byte user ID becomes: f9 a9 38 7f 7d 25 28 42 The NUM part of the encoded domain, located at the position #15 (starting from 0), is a character “6” . Let’s decode it, by taking the first character ( “r” = 114 ), take the reminder of its division by 36 ( 114 % 36 = 6 ), and subtracting the position of the character “6” in the “0123456789abcdefghijklmnopqrstuvwxyz” , which is 6 . The result is 0 . That means the decrypted domain will be the 1st part of the full domain name. The COMPUTER_DOMAIN part of the encrypted domain is “eoip02jovt6i2v0c” . Once decoded, it becomes “city.kingston.” Next, we need to match 2 decrypted domains by the user ID, which is f9 a9 38 7f 7d 25 28 42 in both cases, and concatenate the first and the second parts of the domain. The result will be “city.kingston.on.ca” . String 3 Here comes the most interesting part. Lets try to decrypt the string #3 from our list of passive DNS requests: lt5ai41qh5d53qoti3mkmc0.appsync-api.us-west-2.avsvmcloud.com The decoded user ID is not relevant, as the decoded NUM part is a number -29 . It’s neither 0 nor 1 , so what kind of domain name that is? If we ignore the NUM part and decode the domain name, using the old method, we will get “thx8xb” , which does not look like a valid domain name. Cases like that are not the noise, and are not some artificially encrypted artifacts that showed up among the DNS requests. This is a different type of DNS requests. Instead of encoding local domain names, these types of requests contain data. They are generated by the malware’s function GetNextStringEx() . The encryption method is different as well. Let’s decrypt this request. First, we can decode the encrypted domain, using the same base-64 method, as before . The string will be decoded into 14 bytes: 7c a5 4d 64 9b 21 c1 74 a6 59 e4 5c 7c 7f Let’s decode these bytes, starting from the 2nd byte, and using the first byte as a XOR key. We will get: 7c d9 31 18 e7 5d bd 08 da 25 98 20 00 03 In this array, the bytes marked in yellow are an 8-byte User ID, encoded with a XOR key that is selected from 2 bytes marked in red. Let’s decode User ID: for ( int i = 0 ; i < 8 ; i++) { bytes[i + 1 ] ^= bytes[ 11 - i % 2 ]; } The decoded byte array becomes: 7c f9 a9 38 7f 7d 25 28 42 25 98 20 00 03 The User ID part in marked in yellow. Does it look familiar? Indeed, it’s the same User ID we’ve seen before, when we decoded “city.kingston.on.ca” . The next 3 bytes marked in red are: 25 98 20 . 2 0x59820 The first number 2 stands for the size of data that follows – this data is 00 03 (selected in green). The number 0x59820 , or 366,624 in decimal, is a timestamp. It’s a number of 4-second periods of time since 1 January 2010. To obtain the real time stamp, we need to multiple it by 15 to get minutes, then add those minutes to 1 January 2010: var date = ( new DateTime( 2010 , 1 , 1 , 0 , 0 , 0 , DateTimeKind.Utc)).AddMinutes(timestamp * 15 ); For the number 0x59820 , the time stamp becomes 16 July 2020 12:00:00 AM – that’s the day when the DNS request was made. The remaining 2 bytes, 00 03 , encrypt the state of 8 security products, to indicate whether each one of them is running or whether it is stopped. The 8 security products are: Windows Live OneCare / Windows Defender Windows Defender Advanced Threat Protection Microsoft Defender for Identity Carbon Black CrowdStrike FireEye ESET F-Secure 2 states for 8 products require 2 * 8 = 16 bits = 2 bytes. The 2 bytes 00 03 in binary form are: 00 00 00 00 00 00 00 11 Here, the least-significant bits 11 identify that the first product in the list, Windows Live OneCare / Windows Defender, is reported as ‘running’ ( 1 ) and as ‘stopped’ ( 1 ). Now we know that apart from the local domain, the trojanised SolarWinds software running on the same compromised host on “city.kingston.on.ca” domain has also reported the status of the Windows Defender software. What Does it Mean? As explained in the first part of our description, the malware is capable of stopping the services of security products, be manipulating registry service keys under Administrator account. It’s likely that the attackers are using DNS queries as a C2 channel to first understand what security products are present. Next, the same channel is used to instruct the malware to stop/deactivate these services, before the 2nd stage payload, TearDrop Backdoor, is deployed. Armed with this knowledge, let’s decode other passive DNS requests, printing the cases when the compromised host reports a running security software. NOTES: As a private case, if the data size field is 0 or 1 , the timestamp field is not followed with any data. Such type of DNS request is generated by the malware’s function GetNextString() . It is called ‘a ping’ in the listing below. If the first part of the domain name is missing, the recovered domain name is pre-pended with ‘*’ .

Hey everyone, and welcome! If you're involved in keeping your organization safe online these days, you're in the right place. For years, security felt like building a super strong castle with thick walls and a deep moat, hoping the bad guys would just stay outside. But let's be real, in our multi-cloud world, that castle is starting to look a little... outdated. Think about it: your apps and data aren't neatly tucked away in one place anymore. They're bouncing around on AWS, Azure, GCP, all sorts of platforms – practically everywhere! Trying to handle that with old-school security is like trying to catch smoke with a fishing net. Not gonna work, right? That's why we're chatting today. Gal Yosef, Head of Product Management in the U.S., gets it. He's helped us dive into some crucial mindset shifts – basically, new ways of thinking – that are essential for navigating the craziness of modern security. We gotta ditch the old ways and get ready to be more agile, work together better, and ultimately, be way more effective. Mindset Shift #1: From "Our Stuff is Safe Inside This Box" to "Trust Nothing, Verify Everything" Remember the good old days? We built a perimeter – firewalls, VPNs – thinking that everything inside was safe and sound (danger!). Security was all about guarding that edge. The Problem: Well, guess what? That world is gone! Multi-cloud environments have totally shattered that perimeter. Trying to just secure the network edge leaves your real treasures – your applications, users, and data – vulnerable as they roam across different clouds. It's like locking the front door but leaving all the windows wide open! The New Way: Distributed Trust. Security needs to follow your assets, wherever they go. Instead of just focusing on the infrastructure (the pipes and wires), we need to embrace Zero-Trust principles . Think of it like this: never assume anyone or anything is trustworthy, even if they're "inside." We need identity-based, adaptive security policies that constantly validate trust, rather than just assuming it based on location. Security becomes built into applications and workloads, not just bolted onto the network. Think of it this way: Instead of one big, guarded gate, you have individual, smart locks on every valuable asset. You're constantly checking who's accessing what, no matter where they are. It's like having a personal bodyguard for each of your important things, always making sure they have the right ID. Mindset Shift #2: From "My Team Handles Network Security, Their Team Handles Cloud Security" to "Let's All Be Security Buddies!" Ever feel like your network security team speaks a different language than your cloud security team? You're not alone! Traditionally, these have been separate worlds, with network teams focused on firewalls and cloud teams on security groups. The Problem: These separate silos are a recipe for confusion and fragmented security policies. Attackers? They love this! It's like having cracks in your armor. They aren't always going to bash down the front door; they're often slipping through the gaps created by this lack of communication. The New Way: Cross-functional collaboration. We need to tear down those walls! Network and cloud security teams need to work together, speaking a shared security language. Unified visibility and consistent policies across all your environments are key. Think of it like a superhero team – everyone has their own skills, but they work together seamlessly to fight the bad guys. Regular communication, shared tools, and a common understanding of the risks are crucial. Mindset Shift #3: From "Reacting When Something Breaks" to "Always Watching and Fixing Things Before They Do" Remember the old days of waiting for an alert to pop up saying something was wrong? That's like waiting for your car to break down before you even think about checking the oil. Not the smartest move, right? The Problem: In the fast-paced world of the cloud, waiting for things to go wrong is a recipe for disaster. Attacks can happen super quickly, and by the time you react, the damage might already be done. Plus, manually checking everything all the time? Forget about it – it's just not scalable when you've got stuff spread across multiple clouds. The New Way: Continuous & Automated Enforcement. We need to shift to a mindset of constant monitoring and automated security actions. Think of it like having a security system that's always on, always learning, and can automatically respond to threats in real-time. This means using tools and processes that continuously check for vulnerabilities, enforce security policies automatically, and even predict potential problems before they happen. It's like having a proactive security guard who not only watches for trouble but can also automatically lock doors and sound alarms the moment something looks fishy. Mindset Shift #4: From "Locking Everything Down Tight" to "Finding the Right Balance with Flexible Rules" We used to think the best security was the strictest security – lock everything down, say "no" to everything. But let's be honest, that can make it super hard for people to actually do their jobs! It's like putting so many locks on a door that nobody can actually get through it. The Problem: Overly restrictive security can stifle innovation and slow things down. Developers can get frustrated, and the business can't move as quickly as it needs to. Plus, sometimes those super strict rules can even create workarounds that actually make things less secure in the long run. The New Way: Flexible Guardrails. We need to move towards security that provides clear boundaries (the "guardrails") but also allows for agility and flexibility. Think of it like setting clear traffic laws – you know what's allowed and what's not, but you can still drive where you need to go. This means defining security policies that are adaptable to different cloud environments and business needs. It's about enabling secure innovation, not blocking it. We need to find that sweet spot where security empowers the business instead of hindering it. Mindset Shift #5: From "Security is a Cost Center" to "Security is a Business Enabler" Sometimes, security gets seen as just an expense, something we have to do but doesn't really add value. It's like thinking of insurance as just another bill. The Problem: When security is viewed as just a cost, it often gets underfunded or seen as a roadblock. This can lead to cutting corners and ultimately increasing risk. It's like trying to save money by neglecting the brakes on your car – it might seem cheaper in the short term, but it can have disastrous consequences later. The New Way: Security as a Business Enabler. We need to flip this thinking! Strong security isn't just about preventing bad things from happening; it's about building trust with customers, enabling new business opportunities, and ensuring the long-term resilience of the organization. Think of it like a strong foundation for a building – without it, you can't build anything lasting. By building security into our processes and products from the start, we can actually accelerate innovation and gain a competitive advantage. It's about showing our customers that we take their data seriously and that they can trust us. Wrapping Up: Moving to a multi-cloud world is exciting, but it definitely throws some curveballs at how we think about security. By adopting these five new mindsets, we can ditch the outdated castle mentality and build a more agile, collaborative, and ultimately more secure future for our organizations. It's not about being perfect overnight, but about starting to shift our thinking and embracing these new approaches. So, let's level up our security game together!

Tags Share this article 10/24/23 Published Firewall monitoring is an important part of maintaining strict network security. Every firewall device has an important role to play protecting the network, and unexpected flaws or downtime can put the entire network at risk. Firewall monitoring solutions provide much-needed visibility into the status and behavior of your network firewall setup. They make the security of your IT infrastructure observable, enabling you to efficiently deploy resources towards managing and securing traffic flows. This is especially important in environments with multiple firewall hardware providers, where you may need to verify firewalls, routers, load balancers, and more from a central interface. What is the role of Firewall Monitoring Software? Every firewall in your network is a checkpoint that verifies traffic according to your security policy. Firewall monitoring software assesses the performance and reports the status of each firewall in the network. This is important because a flawed or defective firewall can’t do its job properly. In a complex enterprise IT environment, dedicating valuable resources to manually verifying firewalls isn’t feasible. The organization may have hardware firewalls from Juniper or Cisco, software firewalls from Check Point, and additional built-in operating system firewalls included with Microsoft Windows. Manually verifying each one would be a costly and time-consuming workflow that prevents limited security talent from taking on more critical tasks. Additionally, admins would have to wait for individual results from each firewall in the network. In the meantime, the network would be exposed to vulnerabilities that exploit faulty firewall configurations. Firewall monitoring software solves this problem using automation . By compressing all the relevant data from every firewall in the network into a single interface, analysts and admins can immediately detect security threats that compromise firewall security. The Top 10 Firewall Monitoring Tools Right Now 1. AlgoSec AlgoSec enables security teams to visualize and manage complex hybrid networks . It uses a holistic approach to provide instant visibility to the entire network’s security configuration, including cloud and on-premises infrastructure. This provides a single pane of glass that lets security administrators preview policies before enacting them and troubleshoot issues in real-time. 2. Wireshark Wireshark is a widely used network protocol analyzer. It can capture and display the data traveling back and forth on a network in real-time. While it’s not a firewall-specific tool, it’s invaluable for diagnosing network issues and understanding traffic patterns. As an open-source tool, anyone can download WireShark for free and immediately start using it to analyze data packets. 3. PRTG Network Monitor PRTG is known for its user-friendly interface and comprehensive monitoring capabilities. It supports SNMP and other monitoring methods, making it suitable for firewall monitoring. Although it is an extensible and customizable solution, it requires purchasing a dedicated on-premises server. 4. SolarWinds Firewall Security Manager SolarWinds offers a suite of network management tools, and their Firewall Security Manager is specifically designed for firewall monitoring and management. It helps with firewall rule analysis, change management, and security policy optimization. It is a highly configurable enterprise technology that provides centralized incident management features. However, deploying SolarWinds can be complex, and the solution requires specific on-premises hardware to function. 5. FireMon FireMon is a firewall management and analysis platform. It provides real-time visibility into firewall rules and configurations, helping organizations ensure that their firewall policies are compliant and effective. FireMon minimizes security risks related to policy misconfigurations, extending policy management to include multiple security tools, including firewalls. 6. ManageEngine ManageEngine’s OpManager offers IT infrastructure management solutions, including firewall log analysis and reporting. It can help you track and analyze traffic patterns, detect anomalies, and generate compliance reports. It is intuitive and easy to use, but only supports monitoring devices across multiple networks with its higher-tier Enterprise Edition. It also requires the installation of on-premises hardware. 7. Tufin Tufin SecureTrack is a comprehensive firewall monitoring and management solution. It provides real-time monitoring, change tracking, and compliance reporting for firewalls and other network devices. It can automatically discover network assets and provide comprehensive information on network assets, but may require additional configuration to effectively monitor complex enterprise networks. 8. Cisco Firepower Management Center If you’re using Cisco firewalls, the Firepower Management Center offers centralized management and monitoring capabilities. It provides insights into network traffic, threats, and policy enforcement. Cisco simplifies network management and firewall monitoring by offering an intuitive centralized interface that lets admins control Cisco firewall devices directly. 9. Symantec Symantec (now part of Broadcom) offers firewall appliances with built-in monitoring and reporting features. These appliances are known for providing comprehensive coverage to endpoints like desktop workstations, laptops, and mobile devices. Symantec also provides some visibility into firewall configurations, but it is not a dedicated service built for this purpose. 10. Fortinet Fortinet’s FortiAnalyzer is designed to work with Fortinet’s FortiGate firewalls. It provides centralized logging, reporting, and analysis of network traffic and security events. This provides customers with end-to-end visibility into emerging threats on their networks and even includes useful security automation tools. It’s relatively easy to deploy, but integrating it with a complex set of firewalls may take some time. Benefits of Firewall Monitoring Software Enhanced Security Your firewalls are your first line of defense against cyberattacks, preventing malicious entities from infiltrating your network. Threat actors know this, and many sophisticated attacks start with attempts to disable firewalls or overload them with distributed denial of service (DDoS) attacks. Without a firewall monitoring solution in place, you may not be aware such an attack is happening until it’s too late. Even if your firewalls are successfully defending against the attack, your detection and response team should be ready to start mitigating risk the moment the attack is launched. Traffic Control Firewalls can add strain and latency to network traffic. This is especially true of software firewalls, which have to draw computing resources from the servers they protect. Over time, network congestion can become an expensive obstacle to growth, creating bottlenecks that reduce the efficiency of every device on the network. Improperly implemented firewalls can play a major role in these bottlenecks because they have to verify every data packet transferred through them. With firewall monitoring, system administrators can assess the impact of firewall performance on network traffic and use that data to more effectively balance network loads. Organizations can reduce overhead by rerouting data flows and finding low-cost storage options for data they don’t constantly need access to. Real-time Alerts If attackers manage to break through your defenses and disable your firewall, you will want to know immediately. Part of having a strong security posture is building a multi-layered security strategy. Your detection and response team will need real-time updates on the progress of active cyberattacks. They will use this information to free the resources necessary to protect the organization and mitigate risk. Organizations that don’t have real-time firewall monitoring in place won’t know if their firewalls fail against an ongoing attack. This can lead to a situation where the CSIRT team is forced to act without clear knowledge about what they’re facing. Performance Monitoring Poor network performance can have a profound impact on the profitability of an enterprise-sized organization. Drops in network quality cost organizations more than half a million dollars per year , on average. Misconfigured firewalls can contribute to poor network performance if left unaddressed while the organization grows and expands its network. Properly monitoring the performance of the network requires also monitoring the performance of the firewalls that protect it. System administrators should know if overly restrictive firewall policies prevent legitimate users from accessing the data they need. Policy Enforcement Firewall monitoring helps ensure security policies are implemented and enforced in a standardized way throughout the organization. They can help discover the threat of shadow IT networks made by users communicating outside company-approved devices and applications. This helps prevent costly security breaches caused by negligence. Advanced firewall monitoring solutions can also help security leaders create, save, and update policies using templates. The best of these solutions enable security teams to preview policy changes and research elaborate “what-if” scenarios, and update their core templates accordingly. Selecting the Right Network Monitoring Software When considering a firewall monitoring service, enterprise security leaders should evaluate their choice based on the following features: Scalability Ensure the software can grow with your network to accommodate future needs. Ideally, both your firewall setup and the monitoring service responsible for it can grow at the same pace as your organization. Pay close attention to the way the organization itself is likely to grow over time. A large government agency may require a different approach to scalability than an acquisition-oriented enterprise with many separate businesses under its umbrella. Customizability Look for software that allows you to tailor security rules to your specific requirements. Every organization is unique. The appropriate firewall configuration for your organization may be completely different than the one your closest competitor needs. Copying configurations and templates between organizations won’t always work. Your network monitoring solution should be able to deliver performance insights fine-tuned to your organization’s real needs. If there are gaps in your monitoring capabilities, there are probably going to be gaps in your security posture as well. Integration Compatibility with your existing network infrastructure is essential for seamless operation. This is another area where every organization is unique. It’s very rare for two organizations to use the same hardware and software tools, and even then there may be process-related differences that can become obstacles to easy integration. Your organization’s ideal firewall monitoring solution should provide built-in support for the majority of the security tools the organization uses. If there are additional tools or services that aren’t supported, you should feel comfortable with the process of creating a custom integration without too much difficulty. Reporting Comprehensive reporting features provide insights into network activity and threats. It should generate reports that fit the formats your analysts are used to working with. If the learning curve for adopting a new technology is too high, achieving buy-in will be difficult. The best network monitoring solutions provide a wide range of reports into every aspect of network and firewall performance. Observability is one of the main drivers of value in this kind of implementation, and security leaders have no reason to accept compromises here. AlgoSec for Real-time Network Traffic Analysis Real-time network traffic monitoring reduces security risks and enables faster, more significant performance improvements at enterprise scale. Security professionals and network engineers need access to clear, high-quality insight on data flows and network performance, and AlgoSec delivers. One way AlgoSec deepens the value of network monitoring is through the ability to connect applications directly to security policy rules . When combined with real-time alerts, this provides deep visibility into the entire network while reducing the need to conduct time-consuming manual queries when suspicious behaviors or sub-optimal traffic flows are detected. Firewall Monitoring Software: FAQs How Does Firewall Monitoring Software Work? These software solutions manage firewalls so they can identify malicious traffic flows more effectively. They connect multiple hardware and software firewalls to one another through a centralized interface. Administrators can gather information on firewall performance, preview or change policies, and generate comprehensive reports directly. This enables firewalls to detect more sophisticated malware threats without requiring the deployment of additional hardware. How often should I update my firewall monitoring software? Regular updates are vital to stay protected against evolving threats. When your firewall vendor releases an update, it often includes critical security data on the latest emerging threats as well as patches for known vulnerabilities. Without these updates, your firewalls may become vulnerable to exploits that are otherwise entirely preventable. The same is true for all software, but it’s especially important for firewalls. Can firewall monitoring software prevent all cyberattacks? While highly effective, no single security solution is infallible. Organizations should focus on combining firewall monitoring software with other security measures to create a multi-layered security posture. If threat actors successfully disable or bypass your firewalls, your detection and response team should receive a real-time notification and immediately begin mitigating cyberattack risk. Is open-source firewall monitoring software a good choice? Open-source options can be cost-effective, but they may require more technical expertise to configure and maintain. This is especially true for firewall deployments that rely on highly customized configurations. Open-source architecture can make sense in some cases, but may present challenges to scalability and the affordability of hiring specialist talent later on. How do I ensure my firewall doesn’t block legitimate traffic? Regularly review and adjust your firewall rules to avoid false positives. Sophisticated firewall solutions include features for reducing false positives, while simpler firewalls are often unable to distinguish genuine traffic from malicious traffic. Advanced firewall monitoring services can help you optimize your firewall deployment to reduce false positives without compromising security. How does firewall monitoring enhance overall network security? Firewalls can address many security threats, from distributed denial of service (DDoS) attacks to highly technical cross-site scripting attacks. The most sophisticated firewalls can even block credential-based attacks by examining outgoing content for signs of data exfiltration. Firewall monitoring allows security leaders to see these processes in action and collect data on them, paving the way towards continuous security improvement and compliance. What is the role of VPN audits in network security? Advanced firewalls are capable of identifying VPN connections and enforcing rules specific to VPN traffic. However, firewalls are not generally capable of decrypting VPN traffic, which means they must look for evidence of malicious behavior outside the data packet itself. Firewall monitoring tools can audit VPN connections to determine if they are harmless or malicious in nature, and enforce rules for protecting enterprise assets against cybercriminals equipped with secure VPNs . What are network device management best practices? Centralizing the management of network devices is the best way to ensure optimal network performance in a rapid, precise way. Organizations that neglect to centralize firewall and network device management have to manually interact with increasingly complex fleets of network hardware, software applications, and endpoint devices. This makes it incredibly difficult to make changes when needed, and increases the risks associated with poor change management when they happen. What are the metrics and notifications that matter most for firewall monitoring? Some of the important parameters to pay attention to include the volume of connections from new or unknown IP addresses, the amount of bandwidth used by the organization’s firewalls, and the number of active sessions on at any given time. Port information is especially relevant because so many firewall rules specify actions based on the destination port of incoming traffic. Additionally, network administrators will want to know how quickly they receive notifications about firewall issues and how long it takes to resolve those issues. What is the role of bandwidth and vulnerability monitoring? Bandwidth monitoring allows system administrators to find out which users and hosts consume the most bandwidth, and how network bandwidth is shared among various protocols. This helps track network performance and provides visibility into security threats that exploit bandwidth issues. Denial of service (DoS) attacks are a common cyberattack that weaponizes network bandwidth. What’s the difference between on-premises vs. cloud-based firewall monitoring? Cloud-based firewall monitoring uses software applications deployed as cloud-enabled services while on-premises solutions are physical hardware solutions. Physical solutions must be manually connected to every device on the network, while cloud-based firewall monitoring solutions can automatically discover assets and IT infrastructure immediately after being deployed. What is the role of configuration management? Updating firewall configurations is an important part of maintaining a resilient security posture. Organizations that fail to systematically execute configuration changes on all assets on the network run the risk of forgetting updates or losing track of complex policies and rules. Automated firewall monitoring solutions allow admins to manage configurations more effectively while optimizing change management. What are some best practices for troubleshooting network issues? Monitoring tools offer much-needed visibility to IT professionals who need to address network problems. These tools help IT teams narrow down the potential issues and focus their time and effort on the most likely issues first. Simple Network Management Protocol (SNMP) monitoring uses a client-server application model to collect information running on network devices. This provides comprehensive data about network devices and allows for automatic discovery of assets on the network. What’s the role of firewall monitoring in Windows environments? Microsoft Windows includes simple firewall functionality in its operating system platform, but it is best-suited to personal use cases on individual endpoints. Organizations need a more robust solution for configuring and enforcing strict security rules, and a more comprehensive way to monitor Windows-based networks as a whole. Platforms like AlgoSec help provide in-depth visibility into the security posture of Windows environments. How do firewall monitoring tools integrate with cloud services? Firewall monitoring tools provide observability to cloud-based storage and computing services like AWS and Azure. Cloud-native monitoring solutions can ingest network traffic coming to and from public cloud providers and make that data available for security analysts. Enterprise security teams achieve this by leveraging APIs to automate the transfer of network performance data from the cloud provider’s infrastructure to their own monitoring platform. What are some common security threats and cyberattacks that firewalls can help mitigate? Since firewalls inspect every packet of data traveling through the network perimeter, they play a critical role detecting and mitigating many different threats and attacks. Simple firewalls can block unsophisticated denial-of-service (DoS) attacks and detect known malware variants. Next-generation firewalls can prevent data breaches by conducting deep packet analysis, identifying compromised applications and user accounts, and even blocking sensitive data from leaving the network altogether. What is the importance of network segmentation and IP address management? Network segmentation protects organizations from catastrophic data breaches by ensuring that even successful cyberattacks are limited in scope. If attackers compromise one part of the network, they will not necessarily have access to every other part. Security teams achieve segmentation in part by effectively managing network IP addresses according to a robust security policy and verifying the effects of policy changes using monitoring software.
