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.

Tags Share this article 8/30/21 Published In this guest blog, Jeff Yager from IT Central Station describes how AlgoSec is perceived by real users and shares how the solution meets their expectations for visibility and monitoring. Business-driven visibility A network and security engineer at a comms service provider agreed, saying, “ The complete and end-to-end visibility and analysis [AlgoSec] provides of the policy rule base is invaluable and saves countless time and effort .” On a related front, according to Srdjan, a senior technical and integration designer at a major retailer, AlgoSec provides a much easier way to process first call resolutions (FCRs) and get visibility into traffic. He said, “With previous vendors, we had to guess what was going on with our traffic and we were not able to act accordingly. Now, we have all sorts of analyses and reports. This makes our decision process, firewall cleanup, and troubleshooting much easier.” Organizations large and small find it imperative to align security with their business processes. AlgoSec provides unified visibility of security across public clouds, software-defined and on-premises networks, including business applications and their connectivity flows. For Mark G., an IT security manager at a sports company, the solution handles rule-based analysis . He said, “AlgoSec provides great unified visibility into all policy packages in one place. We are tracking insecure changes and getting better visibility into network security environment – either on-prem, cloud or mixed.” Notifications are what stood out to Mustafa K., a network security engineer at a financial services firm. He is now easily able to track changes in policies with AlgoSec , noting that “with every change, it automatically sends an email to the IT audit team and increases our visibility of changes in every policy.” Security policy and network analysis AlgoSec’s Firewall Analyzer delivers visibility and analysis of security policies, and enables users to discover, identify, and map business applications across their entire hybrid network by instantly visualizing the entire security topology – in the cloud, on-premises, and everything in between. “It is definitely helpful to see the details of duplicate rules on the firewall,” said Shubham S., a senior technical consultant at a tech services company. He gets a lot of visibility from Firewall Analyzer. As he explained, “ It can define the connectivity and routing . The solution provides us with full visibility into the risk involved in firewall change requests.” A user at a retailer with more than 500 firewalls required automation and reported that “ this was the best product in terms of the flexibility and visibility that we needed to manage [the firewalls] across different regions . We can modify policy according to our maintenance schedule and time zones.” A network & collaboration engineer at a financial services firm likewise added that “ we now have more visibility into our firewall and security environment using a single pane of glass. We have a better audit of what our network and security engineers are doing on each device and are now able to see how much we are compliant with our baseline.” Arieh S., a director of information security operations at a multinational manufacturing company, also used Tufin, but prefers AlgoSec, which “ provides us better visibility for high-risk firewall rules and ease of use.” “If you are looking for a tool that will provide you clear visibility into all the changes in your network and help people prepare well with compliance, then AlgoSec is the tool for you,” stated Miracle C., a security analyst at a security firm. He added, “Don’t think twice; AlgoSec is the tool for any company that wants clear analysis into their network and policy management.” Monitoring and alerts Other IT Central Station members enjoy AlgoSec’s monitoring and alerts features. Sulochana E., a senior systems engineer at an IT firm, said, “ [AlgoSec] provides real-time monitoring , or at least close to real time. I think that is important. I also like its way of organizing. It is pretty clear. I also like their reporting structure – the way we can use AlgoSec to clear a rule base, like covering and hiding rules.” For example, if one of his customers is concerned about different standards , like ISO or PZI levels, they can all do the same compliance from AlgoSec. He added, “We can even track the change monitoring and mitigate their risks with it. You can customize the workflows based on their environment. I find those features interesting in AlgoSec.” AlgoSec helps in terms of firewall monitoring. That was the use case that mattered for Alberto S., a senior networking engineer at a manufacturing company. He said, “ Automatic alerts are sent to the security team so we can react quicker in case something goes wrong or a threat is detected going through the firewall. This is made possible using the simple reports.” Sulochana E. concluded by adding that “AlgoSec has helped to simplify the job of security engineers because you can always monitor your risks and know that your particular configurations are up-to-date, so it reduces the effort of the security engineers.” To learn more about what IT Central Station members think about AlgoSec, visit our reviews page .

Application Connectivity Management Achieving policy-driven application-centric security management for Cisco Nexus Dashboard Orchestrat Jeremiah Cornelius 2 min read Jeremiah Cornelius Short bio about author here Lorem ipsum dolor sit amet consectetur.

Tags Share this article 1/2/24 Published Jeremiah Cornelius, Technical Lead for Alliances and Partners at AlgoSec, discusses how Cisco Nexus Dashboard Orchestrator (NDO) users can achieve policy-driven application-centric security management with AlgoSec. Leading Edge of the Data Center with AlgoSec and Cisco NDO AlgoSec ASMS A32.6 is our latest release to feature a major technology integration, built upon our well-established collaboration with Cisco — bringing this partnership to the front of the Cisco innovation cycle with support for Nexus Dashboard Orchestrator (NDO) . NDO allows Cisco ACI – and legacy-style Data Center Network Management – to operate at scale in a global context, across data center and cloud regions. The AlgoSec solution with NDO brings the power of our intelligent automation and software-defined security features for ACI, including planning, change management, and microsegmentation, to this global scope. I urge you to see what AlgoSec delivers for ACI with multiple use cases, enabling application-mode operation and microsegmentation, and delivering integrated security operations workflows. AlgoSec now brings support for Shadow EPG and Inter-Site Contracts with NDO, to our existing ACI strength. Let’s Change the World by Intent I had my first encounter with Cisco Application Centric Infrastructure in 2014 at a Symantec Vision conference. The original Senior Product Manager and Technical Marketing lead were hosting a discussion about the new results from their recent Insieme acquisition and were eager to onboard new partners with security cases and added operations value. At the time I was promoting the security ecosystem of a different platform vendor, and I have to admit that I didn’t fully understand the tremendous changes that ACI was bringing to security for enterprise connectivity. It’s hard to believe that it’s now seven years since then and that Cisco ACI has mainstreamed software-defined networking — changing the way that network teams had grown used to running their networks and devices since at least the mid-’90s. Since that 2014 introduction, Cisco’s ACI changed the landscape of data center networking by introducing an intent-based approach, over earlier configuration-centric architecture models. This opened the way for accelerated movement by enterprise data centers to meet their requirements for internal cloud deployments, new DevOps and serverless application models, and the extension of these to public clouds for hybrid operation – all within a single networking technology that uses familiar switching elements. Two new, software-defined artifacts make this possible in ACI: End-Point Groups (EPG) and Contracts – individual rules that define characteristics and behavior for an allowed network connection. ACI Is Great, NDO Is Global That’s really where NDO comes into the picture. By now, we have an ACI-driven data center networking infrastructure, with management redundancy for the availability of applications and preserving their intent characteristics. Through the use of an infrastructure built on EPGs and contracts, we can reach from the mobile and desktop to the datacenter and the cloud. This means our next barrier is the sharing of intent-based objects and management operations, beyond the confines of a single data center. We want to do this without clustering types, that depend on the availability risk of individual controllers, and hit other limits for availability and oversight. Instead of labor-intensive and error-prone duplication of data center networks and security in different regions, and for different zones of cloud operation, NDO introduces “stretched” shadow EPGs, and inter-site contracts, for application-centric and intent-based, secure traffic which is agnostic to global topologies – wherever your users and applications need to be. NDO Deployment Topology – Image: Cisco Getting NDO Together with AlgoSec: Policy-Driven, App-Centric Security Management  Having added NDO capability to the formidable shared platform of AlgoSec and Cisco ACI, regional-wide and global policy operations can be executed in confidence with intelligent automation. AlgoSec makes it possible to plan for operations of the Cisco NDO scope of connected fabrics in application-centric mode, unlocking the ACI super-powers for micro-segmentation. This enables a shared model between networking and security teams for zero-trust and defense-in-depth, with accelerated, global-scope, secure application changes at the speed of business demand — within minutes, rather than days or weeks. Change management : For security policy change management this means that workloads may be securely re-located from on-premises to public cloud, under a single and uniform network model and change-management framework — ensuring consistency across multiple clouds and hybrid environments. Visibility : With an NDO-enabled ACI networking infrastructure and AlgoSec’s ASMS, all connectivity can be visualized at multiple levels of detail, across an entire multi-vendor, multi-cloud network. This means that individual security risks can be directly correlated to the assets that are impacted, and a full understanding of the impact by security controls on an application’s availability. Risk and Compliance : It’s possible across all the NDO connected fabrics to identify risk on-premises and through the connected ACI cloud networks, including additional cloud-provider security controls. The AlgoSec solution makes this a self-documenting system for NDO, with detailed reporting and an audit trail of network security changes, related to original business and application requests. This means that you can generate automated compliance reports, supporting a wide range of global regulations, and your own, self-tailored policies. The Road Ahead Cisco NDO is a major technology and AlgoSec is in the early days with our feature introduction, nonetheless, we are delighted and enthusiastic about our early adoption customers. Based on early reports with our Cisco partners, needs will arise for more automation, which would include the “zero-touch” push for policy changes – committing Shadow EPG and Inter-site Contract changes to the orchestrator, as we currently do for ACI APIC. Feedback will also shape a need for automation playbooks and workflows that are most useful in the NDO context, and that we can realize with a full committable policy by the ASMS Firewall Analyzer. Contact Us! I encourage anyone interested in NDO and enhancing their operational maturity in aligned network and security operation, to talk to us about our joint solution. We work together with Cisco teams and resellers and will be glad to share more.

Organizations no longer keep their data in one centralized location. Users and assets responsible for processing data may be located... Zero Trust How to Create a Zero Trust Network Tsippi Dach 2 min read Tsippi Dach Short bio about author here Lorem ipsum dolor sit amet consectetur. Vitae donec tincidunt elementum quam laoreet duis sit enim. Duis mattis velit sit leo diam. Tags Share this article 2/12/24 Published Organizations no longer keep their data in one centralized location. Users and assets responsible for processing data may be located outside the network, and may share information with third-party vendors who are themselves removed from those external networks. The Zero Trust approach addresses this situation by treating every user, asset, and application as a potential attack vector whether it is authenticated or not. This means that everyone trying to access network resources will have to verify their identity, whether they are coming from inside the network or outside. What are the Zero Trust Principles and Concepts? The Zero Trust approach is made up of six core concepts that work together to mitigate network security risks and reduce the organization’s attack surface. 1. The principle of least privilege Under the Zero Trust model, network administrators do not provide users and assets with more network access than strictly necessary. Access to data is also revoked when it is no longer needed. This requires security teams to carefully manage user permissions , and to be able to manage permissions based on users’ identities or roles. The principle of least privilege secures the enterprise network ecosystem by limiting the amount of damage that can result from a single security failure. If an attacker compromises a user’s account, it won’t automatically gain access to a wide range of systems, tools, and workloads beyond what that account is provisioned for. This can also dramatically simplify the process of responding to security events, because no user or asset has access to assets beyond the scope of their work. 2. Continuous data monitoring and validation Zero trust policy assumes that there are attackers both inside and outside the network. To guarantee the confidentiality, integrity, and availability of network assets, it must continuously evaluate users and assets on the network. User identity and privileges must be checked periodically along with device identity and security. Organizations accomplish this in a variety of ways. Connection and login time-outs are one way to ensure periodic monitoring and validation since it requires users to re-authenticate even if they haven’t done anything suspicious. This helps protect against the risk of threat actors using credential-based attacks to impersonate authenticated users, as well as a variety of other attacks. 3. Device access control Organizations undergoing the Zero Trust journey must carefully manage and control the way users interact with endpoint devices. Zero Trust relies on verifying and authenticating user identities separately from the devices they use. For example, Zero Trust security tools must be able to distinguish between two different individuals using the same endpoint device. This approach requires fundamental changes to the way certain security tools work. For example, firewalls that allow or deny access to network assets based purely on IP address and port information aren’t sufficient. Most end users have more than one device at their disposal, and it’s common for mobile devices to change IP addresses. As a result, the cybersecurity tech stack needs to be able to grant and revoke permissions based on the user’s actual identity or role. 4. Network micro segmentation Network segmentation is a good security practice even outside the Zero Trust framework, but it takes on special significance when threats can come from inside and outside the network. Microsegmentation takes this one step further by breaking regular network segments down into small zones with their own sets of permissions and authorizations. These microsegments can be as small as a single asset, and an enterprise data center may have dozens of separately secured zones like these. Any user or asset with permission to access one zone will not necessarily have access to any of the others. Microsegmentation improves security resilience by making it harder for attackers to move between zones. 5. Detecting lateral movement Lateral movement is when threat actors move from one zone to another in the network. One of the benefits of micro segmentation is that threat actors must interact with security tools in order to move between different zones on the network. Even if the attackers are successful, their activities generate logs and audit trails that analysts can follow when investigating security incidents. Zero Trust architecture is designed to contain attackers and make it harder for them to move laterally through networks. When an attack is detected, the compromised asset can be quarantined from the rest of the network. Assets can be as small as individual devices or user accounts, or as large as entire network segments. The more granular your security architecture is, the more choices you have for detecting and preventing lateral movement on the network. 6. Multi-factor authentication (MFA) Passwords are a major problem for traditional security models, because most security tools automatically extend trust to anyone who knows the password. Once a malicious actor learns a privileged user’s login credentials, they can bypass most security checks by impersonating that user. Multi-factor authentication solves that problem by requiring users to provide more information. Knowing a password isn’t enough – users must authenticate by proving their identity in another way. These additional authentication factors can come in the form of biometrics, challenge/response protocols, or hardware-based verifications. How To Implement a Zero Trust Network 1. Map Out Your Attack Surface There is no one-size-fits-all solution for designing and implementing Zero Trust architecture. You must carefully define your organization’s attack surface and implement solutions that protect your most valuable assets. This will require a variety of tools, including firewalls, user access controls, permissions, and encryption. You will need to segment your network into individual zones and use microsegmentation to secure high-value and high-volume zones separately. Pay close attention to how your organization secures its most important assets and connections: Sensitive data . This might include customer and employee data, proprietary information, and intellectual property that you can’t allow threat actors to gain access to. It should benefit from the highest degree of security. Critical applications. These applications play a central role in your organization’s business processes, and must be protected against the risk of disruption. Many of them process sensitive data and must benefit from the same degree of security. Physical assets. This includes everything from customer-facing kiosks to hardware servers located in a data center. Access control is vital for preventing malicious actors from interacting with physical assets. Third-party services. Your organization relies on a network of partners and service providers, many of whom need privileged access to your data. Your Zero Trust policy must include safeguards against attacks that compromise third-party partners in your supply chain. 2. Implement Zero Trust Controls using Network Security Tools The next step in your Zero Trust journey is the implementation of security tools that allow you collect, analyze, and respond to user behaviors on your network. This may require the adjustment of your existing security tech stack, and the addition of new tools designed for Zero Trust use cases. Firewalls must be able to capture connection data beyond the traditional IP, port, and protocol data that most simple solutions rely on. The Zero Trust approach requires inspecting the identities of users and assets that connect with network assets, which requires more advanced firewall technology. This is possible with next generation firewall (NGFW) technology. VPNs may need to be reconfigured or replaced because they do not typically enforce the principle of least privilege. Usually, VPNs grant users access to the entire connected network – not just one small portion of it. In most cases, organizations pursuing Zero Trust stop using VPNs altogether because they no longer provide meaningful security benefits. Zero Trust Network Access (ZTNA) provides secure access to network resources while concealing network infrastructure and services. It is similar to a software-defined perimeter that dynamically responds to network changes and grants flexibility to security policies. ZTNA works by establishing one-to-one encrypted connections between network assets, making imprecise VPNs largely redundant. 3. Configure for Identity and Access Management Identity-based monitoring is one of the cornerstones of the Zero Trust approach. In order to accurately grant and revoke permissions to users and assets on the network, you must have some visibility into the identities behind the devices being used. Zero Trust networks verify user identities in a variety of ways. Some next-generation firewalls can distinguish between user traffic, device traffic, application traffic, and content. This allows the firewall to assign application sessions to individual users and devices, and inspect the data being transmitted between individuals on networks. In practice, this might mean configuring a firewall to compare outgoing content traffic with an encrypted list of login credentials. If a user accidentally logs onto a spoofed phishing website and enters their login credentials, the firewall can catch the data before it is transferred off the network. This would not be possible without the ability to distinguish between different types of traffic using next-generation firewall technology. Multi-factor authentication is also vital to identity and access management. A Zero Trust network should not automatically authenticate a user who presents the correct username and password combination to access a secure account. This does not prove the identity of the individual who owns the account – it only proves that the individual knows the username and password. Additional verification factors make it more likely that this person is, in fact, the owner of the account. 4. Create a Zero Trust Policy for Your IT Environment The process of implementing Zero Trust policies in cloud-native environments can be complex. Every third-party vendor and service provider has a role to play in establishing and maintaining Zero Trust. This often puts significant technical demands on third-party partners, which may require organizations to change their existing agreements. If a third-party partner cannot support Zero Trust, they can’t be allowed onto the network. The same is true for on-premises and data center environments, but with added emphasis on physical security and access control. Security leaders need to know who has physical access to servers and similar assets so they can conduct investigations into security incidents properly. Data centers need to implement strict controls on who interacts with protected equipment and how their access is supervised. How to Operationalize Zero Trust Your Zero Trust implementation will not automatically translate to an operational security context that you can immediately use. You will need to adopt security operations that reflect the Zero Trust strategy and launch adaptive security measures that address vulnerabilities in real-time. Gain visibility into your network. Your network perimeter is no longer strictly defined by its hardware. It consists of cloud resources, automated workflows, operating systems, and more. You won’t be able to enforce Zero Trust without gaining visibility into every aspect of your network environment. Monitor network infrastructure and traffic. Your security team will need to monitor and respond to access requests coming from inside and outside your network. This can lead to significant bottlenecks if your team is not equipped with solutions for automatically managing network traffic and access. Streamline detection and response. Zero Trust networks mitigate the risks of cyberattacks, malware, ransomware, and other potential threats, but it’s still up to individual security analysts to detect and investigate security incidents. The volume of data analysts must inspect may increase significantly, so you should be prepared to mitigate the issue of alert fatigue. Automate Endpoint Security. Consider implementing an automated Endpoint Detection and Response (EDR) solution that can identify malicious behaviors on network devices and address them in real-time.

Tags Share this article 8/19/21 Published Kyle Wickert explains how organizations can balance the need to modernize their networks without compromising security For businesses of all shapes and sizes, the inherent value in moving enterprise applications into the cloud is beyond question. The ability to control computing capability at a more granular level can lead to significant cost savings, not to mention the speed at which new applications can be provisioned. Having a modern cloud-based infrastructure makes businesses more agile, allowing them to capitalize on market forces and other new opportunities much quicker than if they depended on on-premises, monolithic architecture alone. However, there is a very real risk that during the goldrush to modernized infrastructures, particularly during the pandemic when the pressure to migrate was accelerated rapidly, businesses might be overlooking the potential blind spot that threatens all businesses indiscriminately, and that is security. One of the biggest challenges for business leaders over the past decade has been managing the delicate balance between infrastructure upgrades and security. Our recent survey found that half of organizations who took part now run over 41% of workloads in the public cloud, and 11% reported a cloud security incident in the last twelve months. If businesses are to succeed and thrive in 2021 and beyond, they must learn how to walk this tightrope effectively. Let’s consider the highs and lows of modernizing legacy infrastructures, and the ways to make it a more productive experience. What are the risks in moving to the cloud? With cloud migration comes risk. Businesses that move into the cloud actually stand to lose a great deal if the process isn’t managed effectively. Moreover, they have some important decisions to make in terms of how they handle application migration. Do they simply move their applications and data into the cloud as they are as a ‘lift and shift’, or do they seek to take a more cloud-native approach and rebuild applications in the cloud to take full advantage of its myriad benefits? Once a business has started this move toward the cloud, it’s very difficult to rewind the process and unpick mistakes that may have been made, so planning really is critical. Then there’s the issue of attack surface area. Legacy on-premises applications might not be the leanest or most efficient, but they are relatively secure by default due to their limited exposure to external environments. Moving said applications onto the cloud has countless benefits to agility, efficiency, and cost, but it also increases the attack surface area for potential hackers. In other words, it gives bots and bad actors a larger target to hit. One of the many traps that businesses fall into is thinking that just because an application is in the cloud, it must be automatically secure. In fact, the reverse is true unless proper due diligence is paid to security during the migration process. The benefits of an app-centric approach One of the ways in which AlgoSec helps its customer master security in the cloud is by approaching it from an app-centric perspective. By understanding how a business uses its applications, including its connectivity paths through the cloud, data centers and SDN fabrics, we can build an application model that generates actionable insights such as the ability to create policy-based risks instead of leaning squarely on firewall controls. This is of particular importance when moving legacy applications onto the cloud. The inherent challenge here is that a business is typically taking a vulnerable application and making it even more vulnerable by moving it off-premise, relying solely on the cloud infrastructure to secure it. To address this, businesses should rank applications in order of sensitivity and vulnerability. In doing so, they may find some quick wins in terms of moving modern applications into the cloud that have less sensitive data. Once these short-term gains are dealt with, NetSecOps can focus on the legacy applications that contain more sensitive data which may require more diligence, time, and focus to move or rebuild securely. Migrating applications to the cloud is no easy feat and it can be a complex process even for the most technically minded NetSecOps. Automation takes a large proportion of the hard work away and enables teams to manage cloud environments efficiently while orchestrating changes across an array of security controls. It brings speed and accuracy to managing security changes and accelerates audit preparation for continuous compliance. Automation also helps organizations overcome skills gaps and staffing limitations. We are likely to see conflict between modernization and security for some time. On one hand, we want to remove the constraints of on-premises infrastructure as quickly as possible to leverage the endless possibilities of cloud. On the other hand, we have to safeguard against the opportunistic hackers waiting on the fray for the perfect time to strike. By following the guidelines set out in front of them, businesses can modernize without compromise.

Security Policy Management Managing network connectivity during mergers and acquisitions Prof. Avishai Wool 2 min read Prof. Avishai Wool 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 7/22/21 Published Prof. Avishai Wool discusses the complexities of mergers and acquisitions for application management and how organizations can securely navigate the transition It comes as no surprise that the number of completed Mergers and Acquisitions (M&As) dropped significantly during the early stages of the pandemic as businesses closed ranks and focused on surviving rather than thriving. However, as we start to find some reprieve, many experts forecast that we’ll see an upturn in activity. In fact, by the end of 2020, M&A experienced a sudden surge and finished the year with only a 3% decline on 2019 levels. Acquiring companies is more than just writing a cheque. There are hundreds of things to consider both big and small, from infrastructure to staffing, which can make or break a merger. With that in mind, what do businesses need to do in order to ensure a secure and successful transition? When two worlds collide For many businesses, a merger or acquisition is highly charged. There’s often excitement about new beginnings mixed with trepidation about major business changes, not least when it comes to IT security. Mergers and acquisitions are like two planets colliding, each with their own intricate ecosystem. You have two enterprises running complex IT infrastructures with hundreds if not thousands of applications that don’t just simply integrate together. More often than not they perform replicated functions, which implies that some need to be used in parallel, while others need to be decommissioned and removed. This means amending, altering, and updating thousands of policies to accommodate new connections, applications, servers, and firewalls without creating IT security risks or outages. In essence, from an IT security perspective, a merger or acquisition is a highly complicated project that, if not planned and implemented properly, can have a long-term impact on business operations. Migrating and merging infrastructures One thing a business will need before it can even start the M&A process is an exhaustive inventory of all business applications spanning both businesses. An auto-discovery tool can assist here, collecting data from any application that is active on the network and adding it to a list. This should allow the main business to create a map of network connectivity flows which will form the cornerstone of the migration from an application perspective. Next comes security. A vulnerability assessment should be carried across both enterprise networks to identify any business-critical applications that may be put at risk. This assessment will give the main business the ability to effectively ‘rank’ applications and devices in terms of risk and necessity, allowing for priority lists to be created. This will help SecOps focus their efforts on crucial areas of the business that contain sensitive customer data, for instance. By following these steps you’ll get a clear organizational view of the entire enterprise environment and be able to identify and map all the critical business applications, linking vulnerabilities and cyber risks to specific applications and prioritize remediation actions based on business-driven needs. The power of automation While the steps outlined above will give you with an accurate picture of your IT topology and its business risk, this is only the first half of the story. Now you need to update security policies to support changes to business applications. Automation is critical when it comes to maintaining security during a merger or acquisition. An alarming number of data breaches are due to firewall misconfigurations, often resulting from attempts to change policies manually in a complex network environment. This danger increases with M&A, because the two merging enterprises likely have different firewall setups in place, often mixing traditional with next-generation firewalls or firewalls that come from different vendors. Automation is therefore essential to ensure the firewall change management process is handled effectively and securely with minimal risk of misconfigurations. Achieving true Zero-Touch automation in the network security domain is not an easy task but over time, you can let your automation solution run handsfree as you conduct more changes and gain trust through increasing automation levels step by step. Our Security Management Solution enables IT and security teams to manage and control all their security devices – from cloud controls in public clouds, SDNs, and on-premise firewalls from one single console. With AlgoSec you can automate time-consuming security policy changes and proactively assess risk to ensure continuous compliance. It is our business-driven approach to security policy management that enables organizations to reduce business risk, ensure security and continuous compliance, and drive business agility. Maintaining security throughout the transition A merger or acquisition presents a range of IT challenges but ensuring business applications can continue to run securely throughout the transition is critical. If you take an application centric approach and utilize automation, you will be in the best position for the merger/migration and will ultimately drive long term success.

Cloud Security Don’t Neglect Runtime Container Security 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 9/21/20 Published The Web application and service business loves containers, but they present a security challenge. Prevasio has the skills and experience to meet the challenge. Its runtime scanning technology and techniques will let you avoid the serious risks of vulnerable or compromised containers. The very thing that makes Docker containers convenient — their all-in-one, self-contained structure — makes them opaque to traditional security tests. Instances come and go as needed, sometimes deleting themselves within seconds. This scalable and transient nature isn’t amenable to the usual tools. Prevasio’s approach is specifically designed to analyze and test containers safely, finding any problems before they turn into security incidents. The container supply chain Container images put together code from many sources. They include original source or binary code, application libraries,language support, and configuration data. The developer puts them all together and delivers the resulting image. A complex container has a long supply chain,and many things can go wrong. Each item in the image could carry a risk. The container developer could use buggy or outdated components, or it could use them improperly. The files it imports could be compromised. A Docker image isn’t a straightforward collection of files, like a gzip file. An image may be derived from another image. Extracting all its files and parameters is possible but not straightforward. Vulnerabilities and malicious actions We can divide container risks into two categories: vulnerabilities and malicious code. Vulnerabilities A vulnerability unintentionally introduces risk. An outsider can exploit them to steal information or inflict damage. In a container, they can result from poor-quality or outdated components. The building process for a complex image is hard to keep up to date. There are many ways for something to go wrong. Vulnerability scanners don’t generally work on container images. They can’t find all the components. It’s necessary to check an active container to get adequate insight. This is risky if it’s done in a production environment. Container vulnerabilities include configuration weaknesses as well as problems in code. An image that uses a weak password or unnecessarily exposes administrative functions is open to attacks. Malicious code Malware in a container is more dangerous than vulnerabilities. It could intrude at any point in the supply chain. The developer might receive a compromised version of a runtime library. A few unscrupulous developers put backdoors into code that they ship. Sometimes they add backdoors for testing purposes and forget to remove them from the finished product. The only way to catch malware in a container is by its behavior. Monitoring the network and checking the file system for suspicious changes will discover misbehaving code. The Prevasio solution Security tools designed for statically loaded code aren’t very helpful with containers. Prevasio has created a new approach that analyzes containers without making any assumptions about their safety. It loads them into a sandboxed environment where they can’t do any harm and analyzes them.The analysis includes the following: Scanning of components for known vulnerabilities Automated pen-test attacks Behavioral analysis of running code Traffic analysis to discover suspicious data packets Machine learning to identify malicious binaries The analysis categorizes an image as benign,vulnerable, exploitable, dangerous, or harmful. The administrator looks at agraph to identify any problems visually, without digging through logs. They can tell at a glance whether an image is reasonably safe to run, needs to be sent back for fixes, or should be discarded on the spot. If you look at competing container security solutions, you’ll find that the key is runtime technology. Static analysis, vulnerability scans, and signature checking won’t get you enough protection by themselves. Prevasio gives you the most complete and effective checking of container images, helping you to avoid threats to your data and your business.

Hybrid Cloud Security Management Securing Cloud-Native Environments: Containerized Applications, Serverless Architectures, and Microservices Malcom Sargla 2 min read Malcom Sargla 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 9/6/23 Published Enterprises are embracing cloud platforms to drive innovation, enhance operational efficiency, and gain a competitive edge. Cloud services provided by industry giants like Google Cloud Platform (GCP), Azure, AWS, IBM, and Oracle offer scalability, flexibility, and cost-effectiveness that make them an attractive choice for businesses. One of the significant trends in cloud-native application development is the adoption of containerized applications, serverless architectures, and microservices. While these innovations bring numerous benefits, they also introduce unique security risks and vulnerabilities that organizations must address to ensure the safety of their cloud-native environments. The Evolution of Cloud-Native Applications Traditionally, organizations relied on on-premises data centers and a set of established security measures to protect their critical applications and data. However, the shift to cloud-native applications necessitates a reevaluation of security practices and a deeper understanding of the challenges involved. Containers: A New Paradigm Containers have emerged as a game-changer in the world of cloud-native development. They offer a way to package applications and their dependencies, ensuring consistency and portability across different environments. Developers appreciate containers for their ease of use and rapid deployment capabilities, but this transition comes with security implications that must not be overlooked. One of the primary concerns with containers is the need for continuous scanning and vulnerability assessment. Developers may inadvertently include libraries with known vulnerabilities, putting the entire application at risk. To address this, organizations should leverage container scanning tools that assess images for vulnerabilities before they enter production. Tools like Prevasio’s patented network sandbox provide real-time scanning for malware and known Common Vulnerabilities and Exposures (CVEs), ensuring that container images are free from threats. Continuous Container Monitoring The dynamic nature of containerized applications requires continuous monitoring to ensure their health and security. In multi-cloud environments, it’s crucial to have a unified monitoring solution that covers all services consistently. Blind spots must be eliminated to gain full control over the cloud deployment. Tools like Prevasio offer comprehensive scanning of asset classes in popular cloud providers such as Amazon AWS, Microsoft Azure, and Google GCP. This includes Lambda functions, S3 buckets, Azure VMs, and more. Continuous monitoring helps organizations detect anomalies and potential security breaches early, allowing for swift remediation. Intelligent and Automated Policy Management As organizations scale their cloud-native environments and embrace the agility that developers demand, policy management becomes a critical aspect of security. It’s not enough to have static policies; they must be intelligent and adaptable to evolving threats and requirements. Intelligent policy management solutions enable organizations to enforce corporate security policies both in the cloud and on-premises. These solutions have the capability to identify and guard against risks introduced through development processes or traditional change management procedures. When a developer’s request deviates from corporate security practices, an intelligent policy management system can automatically trigger actions, such as notifying network analysts or initiating policy work orders. Moreover, these solutions facilitate a “shift-left” approach, where security considerations are integrated into the earliest stages of development. This proactive approach ensures that security is not an afterthought but an integral part of the development lifecycle. Mitigating Risks in Cloud-Native Environments Securing containerized applications, serverless architectures, and microservices in cloud-native environments requires a holistic strategy. Here are some key steps that organizations can take to mitigate risks effectively: 1. Start with a Comprehensive Security Assessment Before diving into cloud-native development, conduct a thorough assessment of your organization’s security posture. Identify potential vulnerabilities and compliance requirements specific to your industry. Understanding your security needs will help you tailor your cloud-native security strategy effectively. 2. Implement Continuous Security Scanning Integrate container scanning tools into your development pipeline to identify vulnerabilities early in the process. Automate scanning to ensure that every container image is thoroughly examined before deployment. Regularly update scanning tools and libraries to stay protected against emerging threats. 3. Embrace Continuous Monitoring Utilize continuous monitoring solutions that cover all aspects of your multi-cloud deployment. This includes not only containers but also serverless functions, storage services, and virtual machines. A unified monitoring approach reduces blind spots and provides real-time visibility into potential security breaches. 4. Invest in Intelligent Policy Management Choose an intelligent policy management solution that aligns with your organization’s security and compliance requirements. Ensure that it offers automation capabilities to enforce policies seamlessly across cloud providers. Regularly review and update policies to adapt to changing security landscapes. 5. Foster a Culture of Security Security is not solely the responsibility of the IT department. Promote a culture of security awareness across your organization. Train developers, operations teams, and other stakeholders on best practices for cloud-native security. Encourage collaboration between security and development teams to address security concerns early in the development lifecycle. Conclusion The adoption of containerized applications, serverless architectures, and microservices in cloud-native environments offers unprecedented flexibility and scalability to enterprises. However, these advancements also introduce new security challenges that organizations must address diligently. By implementing a comprehensive security strategy that includes continuous scanning, monitoring, and intelligent policy management, businesses can harness the power of the cloud while safeguarding their applications and data. As the cloud-native landscape continues to evolve, staying proactive and adaptive in security practices will be crucial to maintaining a secure and resilient cloud environment.

Tags Share this article 7/16/15 Published Common Firewall Threats Do you really know what vulnerabilities currently exist in your enterprise firewalls? Your vulnerability scans are coming up clean. Your penetration tests have not revealed anything of significance. Therefore, everything’s in check, right? Not necessarily. In my work performing independent security assessments , I have found over the years that numerous firewall-related vulnerabilities can be present right under your nose. Sometimes they’re blatantly obvious. Other times, not so much. Here are my top 10 common firewall vulnerabilities that you need to be on the lookout for listed in order of typical significance/priority: Password(s) are set to the default which creates every security problem imaginable, including accountability issues when network events occur. Anyone on the Internet can access Microsoft SQL Server databases hosted internally which can lead to internal database access, especially when SQL Server has the default credentials (sa/password) or an otherwise weak password. Firewall OS software is outdated and no longer supported which can facilitate known exploits including remote code execution and denial of service attacks, and might not look good in the eyes of third-parties if a breach occurs and it’s made known that the system was outdated. Anyone on the Internet can access the firewall via unencrypted HTTP connections, as these can be exploited by an outsider who’s on the same network segment such as an open/unencrypted wireless network. Anti-spoofing controls are not enabled on the external interface which can facilitate denial of service and related attacks. Rules exist without logging which can be especially problematic for critical systems/services. Any protocol/service can connect between internal network segments which can lead to internal breaches and compliance violations, especially as it relates to PCI DSS cardholder data environments. Anyone on the internal network can access the firewall via unencrypted telnet connections. These connections can be exploited by an internal user (or malware) if ARP poisoning is enabled via a tool such as the free password recovery program Cain & Abel . Any type of TCP or UDP service can exit the network which can enable the spreading of malware and spam and lead to acceptable usage and related policy violations. Rules exist without any documentation which can create security management issues, especially when firewall admins leave the organization abruptly. Firewall Threats and Solutions Every security issue – whether confirmed or potential – is subject to your own interpretation and needs. But the odds are good that these firewall vulnerabilities are creating tangible business risks for your organization today. But the good news is that these security issues are relatively easy to fix. Obviously, you’ll want to think through most of them before “fixing” them as you can quickly create more problems than you’re solving. And you might consider testing these changes on a less critical firewall or, if you’re lucky enough, in a test environment. Ultimately understanding the true state of your firewall security is not only good for minimizing network risks, it can also be beneficial in terms of documenting your network, tweaking its architecture, and fine-tuning some of your standards, policies, and procedures that involve security hardening, change management, and the like. And the most important step is acknowledging that these firewall vulnerabilities exist in the first place!

Vitae donec tincidunt elementum quam laoreet duis sit enim. Duis mattis velit sit leo diam. Tags Share this article 2/19/13 Published Podcast: Differences between UTM and NGFW In our recent webcast discussion alongside panelists from Fortinet, NSS Labs and General Motors, we examined the State of the Firewall in 2013. We received more audience questions during the webcast than the time allowed for, so we’d like to answer these questions through several blog posts in a Q&A format with the panelists. By far the most asked question leading up to and during the webcast was: “What’s the difference between a UTM and a Next-Generation Firewall?” Here’s how our panelists responded: Pankil Vyas, Manager – Network Security Center, GM UTM are usually bundled feature set, NGFW has bundle but licensing can be selective. Depending on the firewall’s function on the network, some UTM features might not be useful, creating performance issues and sometimes firewall conflicts with packet flows. Nimmy Reichenberg, VP of Strategy, AlgoSec Different people give different answers to this question, but if we refer to Gartner who are certainly a credible source, a UTM consolidates many security functions (email security, AV, IPS, URL filtering etc.) and is tailored mostly to SMBs in terms of management capabilities, throughput, support, etc. A NGFW is an enterprise-grade product that at the very least includes IPS capabilities and application awareness (layer 7 control). You can refer to a Gartner paper titled “Defining the Next-Generation Firewall” for more information. Ryan Liles, Director of Testing Services, NSS Labs There really aren’t any differences in a UTM and a NGFW. The technologies used in the two are essentially the same, and they generally have the same capabilities. UTM devices are typically classified with lower throughput ratings than their NGFW counterparts, but for all practical purposes the differences are in marketing. The term NGFW was coined by vendors working with Gartner to create a class of products capable of fitting into an enterprise network that contained all of the features of a UTM. The reason for the name shift is that there was a pervasive line of thought stating a device capable of all of the functions of a UTM/NGFW would never be fast enough to run in an enterprise network. As hardware has progressed, the capability of these devices to hit multi-gigabit speeds began to prove that they were indeed capable of enterprise deployment. Rather than try and fight the sentiment that a UTM could never fit into an enterprise, the NGFW was born. Patrick Bedwell, VP of Products, Fortinet There are several definitions in the market of both terms. Analyst firms IDC and Gartner provided the original definitions of the terms. IDC defined UTM as a security appliance that combines firewall, gateway antivirus, and intrusion detection / intrusion prevention (IDS/IPS). Gartner defined an NGFW as a single device with integrated IPS with deep packet scanning, standard first-generation FW capabilities (NAT, stateful protocol inspection, VPN, etc.) and the ability to identity and control applications running on the network. Since their initial definitions, the terms have been used interchangeably by customers as well as vendors. Depending on with whom you speak, UTM can include NGFW features like application ID and control, and NGFW can include UTM features like gateway antivirus. The terms are often used synonymously, as both represent a single device with consolidated functionality. At Fortinet, for example, we offer customers the ability to deploy a FortiGate device as a pure firewall, an NGFW (enabling features like Application Control or User- and Device-based policy enforcement) or a full UTM (enabling additional features like gateway AV, WAN optimization, and so forth). Customers can deploy as much or as little of the technology on the FortiGate device as they need to match their requirements. If you missed the webcast, you can view it on-demand.

Tags Share this article 8/10/15 Published Last week our CTO, Professor Avishai Wool, presented a technical webinar on the do’s and don’ts for managing external connectivity to and from your network . We kicked off our webinar by polling the audience (186 people) on how many external permanent connections into their enterprise network they have. 40% have less than 50 external connections 31% have 50-250 external connections 24% have more than 250 external connections 5% wish they knew how many external connections they have! Clearly this is a very relevant issue for many enterprises, and one which can have a profound effect on security. The webinar covered a wide range of best practices for managing the external connectivity lifecycle and I highly recommend that you view the full presentation. But in the meantime, here are a few key issues that you should be mindful of when considering how to manage external connectivity to and from your network: Network Segmentation While there has to be an element of trust when you let an external partner into your network, you must do all you can to protect your organization from attacks through these connections. These include placing your servers in a demilitarized zone (DMZ), segregating them by firewalls, restricting traffic in both directions from the DMZ as well as using additional controls such as web application firewalls, data leak prevention and intrusion detection. Regulatory Compliance Bear in mind that if the data being accessed over the external connection is regulated, both your systems and the related peer’s systems are now subject t. So if the network connection touches credit card data, both sides of the connection are in scope, and outsourcing the processing and management of regulated data to a partner does not let you off the hook. Maintenance Sometimes you will have to make changes to your external connections, either due to planned maintenance work by your IT team or the peer’s team, or as a result of unplanned outages. Dealing with changes that affect external connections is more complicated than internal maintenance, as it will probably require coordinating with people outside your organisation and tweaking existing workflows, while adhering to any contractual or SLA obligations. As part of this process, remember that you’ll need to ensure that your information systems allow your IT teams to recognize external connections and provide access to the relevant technical information in the contract, while supporting the amended workflows. Contracts In most cases there is a contract that governs all aspects of the external connection – including technical and business issues. The technical points will include issues such as IP addresses and ports, technical contact points, SLAs, testing procedures and the physical location of servers. It’s important, therefore, that this contract is adhered to whenever dealing with technical issues related to external connections. These are just a few tips and issues to be aware of.

As businesses harness the combined power of these transformative technologies, the importance of a security-centric approach becomes increasingly evident. This exploration delves deeper into the strategic significance of navigating the Cloud-AI nexus with a focus on security and innovation. Cloud and AI: catalysts for business transformation The cloud provides the foundational infrastructure, while AI infuses intelligence, making systems smarter and more responsive. Together, they’re reshaping industries, driving efficiencies, and creating new business models. However, with these opportunities come challenges. Ensuring robust security in this intertwined environment is not just a technical necessity but a strategic imperative. As AI algorithms process vast datasets in the cloud, businesses must prioritize the protection and integrity of this data to build and maintain trust. Building trust in intelligent systems In the age of AI, data isn’t just processed; it’s interpreted, analyzed, and acted upon. This autonomous decision-making demands a higher level of trust. Ensuring the confidentiality, integrity, and availability of data in the cloud becomes paramount. Beyond just data protection, it’s about ensuring that AI-driven decisions, which can have real-world implications, are made based on secure and untampered data. This trust forms the bedrock of AI’s value proposition in the cloud. Leadership in the Cloud-AI era Modern leaders are not just visionaries; they’re also gatekeepers. They stand at the intersection of innovation and security, ensuring that as their organizations harness AI in the cloud, ethical considerations and security protocols are front and center. This dual role is challenging but essential. As AI-driven applications become integral to business operations, leaders must champion a culture where security and innovation coexist harmoniously. Seamless integration and the role of DevSecOps Developing AI applications in the cloud is a complex endeavor. It requires a seamless integration of development, operations, and crucially, security. Enter DevSecOps. This approach ensures that security is embedded at every stage of the development lifecycle.
