Tags Share this article 12/20/23 Published How To Reduce Attack Surface: 6 Proven Tactics Security-oriented organizations continuously identify, monitor, and manage internet-connected assets to protect them from emerging attack vectors and potential vulnerabilities. Security teams go through every element of the organization’s security posture – from firewalls and cloud-hosted assets to endpoint devices and entry points – looking for opportunities to reduce security risks. This process is called attack surface management. It provides a comprehensive view into the organization’s cybersecurity posture, with a neatly organized list of entry points, vulnerabilities, and weaknesses that hackers could exploit in a cyberattack scenario. Attack surface reduction is an important element of any organization’s overall cybersecurity strategy. Security leaders who understand the organization’s weaknesses can invest resources into filling the most critical gaps first and worrying about low-priority threats later. What assets make up your organization’s attack surface? Your organization’s attack surface is a detailed list of every entry point and vulnerability that an attacker could exploit to gain unauthorized access. The more entry points your network has, the larger its attack surface will be. Most security leaders divide their attention between two broad types of attack surfaces: The digital attack surface This includes all network equipment and business assets used to transfer, store, and communicate information. It is susceptible to phishing attempts , malware risks, ransomware attacks, and data breaches. Cybercriminals may infiltrate these kinds of assets by bypassing technical security controls, compromising unsecured apps or APIs, or guessing weak passwords. The physical attack surface This includes business assets that employees, partners, and customers interact with physically. These might include hardware equipment located inside data centers and USB access points. Even access control systems for office buildings and other non-cyber threats may be included. These assets can play a role in attacks that involve social engineering, insider threats, and other malicious actors who work in-person. Even though both of these attack surfaces are distinct, many of their security vulnerabilities and potential entry points overlap in real-life threat scenarios. For example, thieves might steal laptops from an unsecured retail location and leverage sensitive data on those devices to launch further attacks against the organization’s digital assets. Organizations that take steps to minimize their attack surface area can reduce the risks associated with this kind of threat. Known Assets, Unknown Assets, and Rogue Assets All physical and digital business assets fall into one of three categories: Known assets are apps, devices, and systems that the security team has authorized to connect to the organization’s network. These assets are included in risk assessments and they are protected by robust security measures, like network segmentation and strict permissions. Unknown assets include systems and web applications that the security team is not aware of. These are not authorized to access the network and may represent a serious security threat. Shadow IT applications may be part of this category, as well as employee-owned mobile devices storing sensitive data and unsecured IoT devices. Rogue assets connect to the network without authorization, but they are known to security teams. These may include unauthorized user accounts, misconfigured assets, and unpatched software. A major part of properly managing your organization’s attack surface involves the identification and remediation of these risks. Attack Vectors Explained: Minimize Risk by Following Potential Attack Paths When conducting attack surface analysis, security teams have to carefully assess the way threat actors might discover and compromise the organization’s assets while carrying out their attack. This requires the team to combine elements of vulnerability management with risk management , working through the cyberattack kill chain the way a hacker might. Some cybercriminals leverage technical vulnerabilities in operating systems and app integrations. Others prefer to exploit poor identity access management policies, or trick privileged employees into giving up their authentication credentials. Many cyberattacks involve multiple steps carried out by different teams of threat actors. For example, one hacker may specialize in gaining initial access to secured networks while another focuses on using different tools to escalate privileges. To successfully reduce your organization’s attack surface, you must follow potential attacks through these steps and discover what their business impact might be. This will provide you with the insight you need to manage newly discovered vulnerabilities and protect business assets from cyberattack. Some examples of common attack vectors include: API vulnerabilities. APIs allow organizations to automate the transfer of data, including scripts and code, between different systems. Many APIs run on third-party servers managed by vendors who host and manage the software for customers. These interfaces can introduce vulnerabilities that internal security teams aren’t aware of, reducing visibility into the organization’s attack surface. Unsecured software plugins. Plugins are optional add-ons that enhance existing apps by providing new features or functionalities. They are usually made by third-party developers who may require customers to send them data from internal systems. If this transfer is not secured, hackers may intercept it and use that information to attack the system. Unpatched software. Software developers continuously release security patches that address emerging threats and vulnerabilities. However, not all users implement these patches the moment they are released. This delay gives attackers a key opportunity to learn about the vulnerability (which is as easy as reading the patch changelog) and exploit it before the patch is installed. Misconfigured security tools. Authentication systems, firewalls, and other security tools must be properly configured in order to produce optimal security benefits. Attackers who discover misconfigurations can exploit those weaknesses to gain entry to the network. Insider threats. This is one of the most common attack vectors, yet it can be the hardest to detect. Any employee entrusted with sensitive data could accidentally send it to the wrong person, resulting in a data breach. Malicious insiders may take steps to cover their tracks, using their privileged permissions and knowledge of the organization to go unnoticed. 6 Tactics for Reducing Your Attack Surface 1. Implement Zero Trust The Zero Trust security model assumes that data breaches are inevitable and may even have already occurred. This adds new layers to the problems that attack surface management resolves, but it can dramatically improve overall resilience and preparedness. When you develop your security policies using the Zero Trust framework, you impose strong limits on what hackers can and cannot do after gaining initial access to your network. Zero Trust architecture blocks attackers from conducting lateral movement, escalating their privileges, and breaching critical data. For example, IoT devices are a common entry point into many networks because they don’t typically benefit from the same level of security that on-premises workstations receive. At the same time, many apps and systems are configured to automatically trust connections from internet-enabled sensors and peripheral devices. Under a Zero Trust framework, these connections would require additional authentication. The systems they connect to would also need to authenticate themselves before receiving data. Multi-factor authentication is another part of the Zero Trust framework that can dramatically improve operational security. Without this kind of authentication in place, most systems have to accept that anyone with the right username and password combination must be a legitimate user. In a compromised credential scenario, this is obviously not the case. Organizations that develop network infrastructure with Zero Trust principles in place are able to reduce the number of entry points their organization exposes to attackers and reduce the value of those entry points. If hackers do compromise parts of the network, they will be unable to quickly move between different segments of the network, and may be unable to stay unnoticed for long. 2. Remove Unnecessary Complexity Unknown assets are one of the main barriers to operational security excellence. Security teams can’t effectively protect systems, apps, and users they don’t have detailed information on. Any rogue or unknown assets the organization is responsible for are almost certainly attractive entry points for hackers. Arbitrarily complex systems can be very difficult to document and inventory properly . This is a particularly challenging problem for security leaders working for large enterprises that grow through acquisitions. Managing a large portfolio of acquired companies can be incredibly complex, especially when every individual company has its own security systems, tools, and policies to take into account. Security leaders generally don’t have the authority to consolidate complex systems on their own. However, you can reduce complexity and simplify security controls throughout the environment in several key ways: Reduce the organization’s dependence on legacy systems. End-of-life systems that no longer receive maintenance and support should be replaced with modern equivalents quickly. Group assets, users, and systems together. Security groups should be assigned on the basis of least privileged access, so that every user only has the minimum permissions necessary to achieve their tasks. Centralize access control management. Ad-hoc access control management quickly leads to unknown vulnerabilities and weaknesses popping up unannounced. Implement a robust identity access management system so you can create identity-based policies for managing user access. 3. Perform Continuous Vulnerability Monitoring Your organization’s attack surface is constantly changing. New threats are emerging, old ones are getting patched, and your IT environment is supporting new users and assets on a daily basis. Being able to continuously monitor these changes is one of the most important aspects of Zero Trust architecture . The tools you use to support attack surface management should also generate alerts when assets get exposed to known risks. They should allow you to confirm the remediation of detected risks, and provide ample information about the risks they uncover. Some of the things you can do to make this happen include: Investing in a continuous vulnerability monitoring solution. Vulnerability scans are useful for finding out where your organization stands at any given moment. Scheduling these scans to occur at regular intervals allows you to build a standardized process for vulnerability monitoring and remediation. Building a transparent network designed for visibility. Your network should not obscure important security details from you. Unfortunately, this is what many third-party security tools and services achieve. Make sure both you and your third-party security partners are invested in building observability into every aspect of your network. Prioritize security expenditure based on risk. Once you can observe the way users, data, and assets interact on the network, you can begin prioritizing security initiatives based on their business impact. This allows you to focus on high-risk tasks first. 4. Use Network Segmentation to Your Advantage Network segmentation is critical to the Zero Trust framework. When your organization’s different subnetworks are separated from one another with strictly protected boundaries, it’s much harder for attackers to travel laterally through the network. Limiting access between parts of the network helps streamline security processes while reducing risk. There are several ways you can segment your network. Most organizations already perform some degree of segmentation by encrypting highly classified data. Others enforce network segmentation principles when differentiating between production and live development environments. But in order for organizations to truly benefit from network segmentation, security leaders must carefully define boundaries between every segment and enforce authentication policies designed for each boundary. This requires in-depth knowledge of the business roles and functions of the users who access those segments, and the ability to configure security tools to inspect and enforce access control rules. For example, any firewall can block traffic between two network segments. A next-generation firewall can conduct identity-based inspection that allows traffic from authorized users through – even if they are using mobile devices the firewall has never seen before. 5. Implement a Strong Encryption Policy Encryption policies are an important element of many different compliance frameworks . HIPAA, PCI-DSS, and many other regulatory frameworks specify particular encryption policies that organizations must follow to be compliant. These standards are based on the latest research in cryptographic security and threat intelligence reports that outline hackers’ capabilities. Even if your organization is not actively seeking regulatory compliance, you should use these frameworks as a starting point for building your own encryption policy. Your organization’s risk profile is largely the same whether you seek regulatory certification or not – and accidentally deploying outdated encryption policies can introduce preventable vulnerabilities into an otherwise strong security posture. Your organization’s encryption policy should detail every type of data that should be encrypted and the cipher suite you’ll use to encrypt that data. This will necessarily include critical assets like customer financial data and employee payroll records, but it also includes relatively low-impact assets like public Wi-Fi connections at retail stores. In each case, you must implement a modern cipher suite that meets your organization’s security needs and replace legacy devices that do not support the latest encryption algorithms. This is particularly important in retail and office settings, where hardware routers, printers, and other devices may no longer support secure encryption. 6. Invest in Employee Training To truly build security resilience into any company culture, it’s critical to explain why these policies must be followed, and what kinds of threats they address. One of the best ways to administer standardized security compliance training is by leveraging a corporate learning platform across the organization, so that employees can actually internalize these security policies through scenario based training courses. It’s especially valuable in organizations suffering from consistent shadow IT usage. When employees understand the security vulnerabilities that shadow IT introduces into the environment, they’re far less likely to ignore security policies for the sake of convenience. Security simulations and awareness campaigns can have a significant impact on training initiatives. When employees know how to identify threat actors at work, they are much less likely to fall victim to them. However, actually achieving meaningful improvement may require devoting a great deal of time and energy into phishing simulation exercises over time – not everyone is going to get it right in the first month or two. These initiatives can also provide clear insight and data on how prepared your employees are overall. This data can make a valuable contribution to your attack surface reduction campaign. You may be able to pinpoint departments – or even individual users – who need additional resources and support to improve their resilience against phishing and social engineering attacks. Successfully managing this aspect of your risk assessment strategy will make it much harder for hackers to gain control of privileged administrative accounts.

Understand how to achieve and maintain firewall compliance with ISO/IEC 27001. Learn key requirements, best practices, and how to strengthen your overall security posture. Firewall ISO compliance: ISO/IEC 27001 explained Introductory prologue IT organizations and those dealing with digital assets often face many information security challenges. They must protect sensitive data from unauthorized access, as a crack in security can result in unimaginable losses. To keep information security risks minimal and optimize protection for organizations, ISO/IEC 27001 compliance was designed. What is ISO/IEC 27001 compliance? How does it work, and why does it matter? Read on to uncover answers to all your questions and more in this guide. Schedule a Demo What Is ISO/IEC 27001? ISO/IEC 27001 is an internationally accepted standard for data security. It is one of the standards jointly published by the ISO (International Standardization Organization) and IEC (International Electrotechnical Commission) in 2015. ISO/IEC 27001 aims to provide organizations with a framework for information security management, thereby protecting digital assets. Implementing the standard helps organizations minimize and effectively manage information security risks, such as hacks, data leaks or theft, and cyber attacks. Digital assets like intellectual property, software, employee information, and personal data are often a target for malicious actors. And that’s why asset management is crucial to companies and digital service providers. It demonstrates that the certified organization’s information security system is efficient as it follows the best practice. Any ISO/IEC 27001-certified organization can display its certification online (e.g., on its website, social media platforms, etc.) and offline. As a result, they get the trust and respect they deserve from partners, investors, customers, and other organizations. Schedule a Demo Evolution of ISO/IEC 27001 The International Standardization Organization (ISO) is a global federation of national standards bodies established in 1947. It is a leading organization that develops standards for ensuring the security of business systems. Since its emergence, ISO has published several standards, such as: ISO 27000 – Information Security Management Systems ISO 22301 – Business Continuity ISO 14000 – Environmental Management System ISO 45001 – Occupational Health and Safety ISO 9000 – Quality Management System etc. Although ISO/IEC 27001 was officially published in 2005, ISO had been providing measures for protecting digital systems and information before then. The rapid spread of the internet in the 1990s gave rise to the need for data security to prevent sensitive data from getting into the wrong hands. ISO 27001 was the first standard among the ISO 27000 series of standards for cybersecurity. Since its release, the standard has undergone revisions to tackle new and evolving cyber threats in the industry. The first revision took place in October 2013, when new controls were introduced, and the total controls numbered up to 114. This version is referred to as ISO/IEC 27001:2013 version. The second and latest revision of ISO/ICE 27001 was published in 2022 and enumerates 93 controls grouped into four sections. This revision was initially referred to as ISO/IEC 27001:2022 but is now known as ISO 27001. Another notable development in the latest version is the change in title. The new version’s complete title is – ISO 27001 (i.e., ISO/IEC 27001:2022) Information Security, Cybersecurity and Privacy Protection. Schedule a Demo Business Benefits of ISO/IEC 27001 Achieving ISO/IEC 27001 certification offers organizations several business benefits, especially for service providers handling people’s sensitive financial and personal data. Examples of such organizations are insurance companies, banks, health organizations, and financial institutions. Some of the business benefits of ISO 27001 are: 1. It prevents financial penalties and losses from data breaches Organizations that do not comply with the global security standard are at great risk of a data breach. Data breaches often attract financial penalties and cause companies to lose significant amounts. By implementing the best network security practices, organizations can prevent unnecessary financial losses and record more significant revenue in the long run. 2. It protects and enhances a company’s reputation. Partners, investors, and customers often prefer companies with a good reputation for handling data. In fact, the World Economic Forum states that reputation affects a quarter of a company’s market value. ISO/IEC 27001 certification can help businesses with an existing reputation to preserve their image. Companies with a previous record of security challenges can enhance their reputation and earn the trust and respect of others by becoming certified too. 3. Wins new business and sharpens competitive edge Certified companies stand a better chance of winning new businesses and recording more sales and profits than their competitors. That’s because clients want to feel safe knowing their data enjoy maximum protection. Also, certain organizations must attain other certifications like GDPR, HIPAA, NIST, etc., before commencing operation. And having ISO certification makes it easier to achieve such requirements. One major indicator that an organization can be trusted for security management is acquiring a worldwide certification. It sharpens its competitive advantage and propels the brand way ahead of others. 4. Improves structure and focus As businesses expand, new responsibilities arise, and it can be challenging to determine who should be responsible for what. But with ISO 27001 compliance, companies will have a clear structure to mirror. From authentication to network traffic management, the standard has an outlined structure that companies can apply to establish robust operations security. As a result, they can tackle rising needs while staying focused and productive. 5. It reduces the need for frequent audits. Organizations usually spend heavily performing frequent internal and external audits to generate valuable data about the state of their security. The data is deployed to improve cybersecurity so that threat intelligence and other security aspects are optimized. And even though it costs more and wastes more time, it doesn’t guarantee as much protection as implementing ISO 27001 standard. By becoming a certified name, companies can rest assured that the best cybersecurity practices protect them against attacks. Plus, frequent audits won’t be needed, thus saving cost and time. Schedule a Demo ISO/IEC 27001 Compliance Organizations looking to achieve ISO/IEC 27001 compliance must ensure the following: 1. Clearly Outline the Risk Assessment Process Develop your risk assessment process to detect vulnerabilities. State the categories of risks your organization is facing Outline your approach to tackle vulnerabilities. 2. Make Sure Executives Set the Tone Top management must be involved in the information security program. They should show financial support and be available to make strategic decisions that will help build robust security. Senior management should also conduct frequent assessments of the company’s ISMS to ensure it’s in sync with the globally agreed security standard. 3. Design an Information Security Policy (ISP) An ISP essentially functions to ensure that all the users and networks of your organization’s IT structure stick with the standard practices of digital data storage. You must design an effective ISP to achieve compliance as it governs information protection. Your ISP should encompass the A to Z of your organization’s IT security, including cloud security. You need to state who will be responsible for implementing the designed policy. 4. Write Out Your Statement of Applicability (SoA) Your SoA should carry core information about your ISMS. It should state the controls that your organization regards necessary to combat information security risks. It should document the controls that were not applied The SoA should only be shared with the certification body. 5. Create Your Risk Management Strategy Develop an effective risk management plan to address the possible risks of your chosen security controls. Ensure there’s an efficient security operations center (soc) to help detect cyber threats and forward notifications to the right systems. Design an information security incident management strategy to respond during threat detection. State who will implement specific security controls, how, and when they will deploy them. Schedule a Demo FAQs What does ISO/IEC 27001 stand for? ISO stands for International Standardization Organization, while IEC represents International Electrotechnical Commission. ISO/IEC 27001 is an internationally accepted standard for information security management, which ISO and IEC first created. What are the ISO 27001 Requirements? Every organization looking to apply for certification must prepare themselves and ensure to meet the requirements. These requirements are summarized in Clauses 4.1 to 10.2 below: 4.1 Understanding the organization and its context 4.2 Understanding the needs and expectations of interested parties 4.3 Determining the scope of the ISMS 4.4 Information security management system (ISMS) 5.1 Leadership and commitment 5.2 Information Security Policy 5.3 Organisational roles, responsibilities, and authorities 6.1 Actions to address risks and opportunities 6.2 Information security objectives and planning to achieve them 7.1 Resources 7.2 Competence 7.3 Awareness 7.4 Communication 7.5 Documented information 8.1 Operational planning and control 8.2 Information security risk assessment 8.3 Information security risk treatment 9.1 Monitoring, measurement, analysis, and evaluation 9.2 Internal audit 9.3 Management review 10.1 Nonconformity and corrective action 10.2 Continual improvement What are the ISO/IEC 27001 controls? The latest version of ISO 27001 Annex A enumerates 93 security controls divided into four sections or themes. The ISO 27001 controls are designed to simplify information security management such that digital assets get the best protection against security threats. These 4 sections are labelled A5 to A8 and are as follows: A.5 Organizational controls – containing 37 controls A.6 People controls – containing 8 controls A.7 Physical controls – containing 14 controls A.8 Technological controls – containing 34 controls How Does ISO/IEC 27001 ensure data protection? ISO/IEC 27001 ensures data protection by providing a framework through which companies can store sensitive data and have full access control. This standard can be adapted to suit each organization’s specific needs and structure, thereby offering optimized protection. ISO/IEC 27001 aims to ascertain that three core information security aspects are taken care of, which are: Confidentiality: this guarantees that only authorized individuals can access information. Also, because organizations deal with different categories of data, each employee must only be given the degree of access required to execute their tasks efficiently. Integrity: this ensures that only authorized individuals can change information on the system. So even in the event of a security breach, the risks are minimal. This is due to the change management plan that ensures unauthorized persons can not alter information. Availability: information security becomes a problem if the secured information isn’t accessible when needed. ISO 27001 enables authorized persons to have access to information whenever required to ensure that business operations are uninterrupted. By maintaining these guidelines, companies can put in place an effective information security system and risk management plan to prevent data leaks, theft, or hacks. How does my firewall management help with ISO 27001? Firewalls are the software in your organization’s IT structure managing the connection between different networks. Effective firewall management can help in designing the right Information Security Policy (ISP). In turn, your organization will be able to achieve ISO 27001 compliance. Thus, your firewall policies can help with ISO 27001 by enabling organizations to design an Information Security Policy that agrees with the standard required for compliance. What is the Importance of ISO 27001 Certification, and how can I gain it? ISO 27001 certification offers several advantages to businesses and organizations. It demonstrates to partners, investors, and customers that the certified business has a reliable information security management system, thus winning their trust. Also, it enhances communications security so that third parties do not interfere with your company’s operating system. You also get to reduce the risk of security failure, saving you from financial losses and penalties.

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.

Learn best practices for effective network firewall security management. Enhance your security posture with proper configuration, monitoring, and maintenance. Network firewall security management What are network firewalls? Network firewalls are the first round of defense against a wide range of external threats. Firewall policies filter incoming traffic to protect the network ecosystem from cyberattacks. Network traffic that doesn’t meet filter criteria gets blocked. Security teams continually optimize their organization’s firewall configuration to address new and emerging threats. Schedule a Demo Network firewall security challenges Network infrastructure is more complex than ever before. In the early days, your network firewall sat at the perimeter of your data center. Today, you may have a variety of firewalls operating on-premises, in public and private clouds, in a software-defined network, or a multi-cloud hybrid environment. Security leaders face four main challenges when implementing, maintaining and improving firewall performance: Complexity – The more individual firewall solutions your network relies on, the harder it is to analyze, configure, and scale firewall-related workflows. Visibility – The traffic flows over your network are complex. Lack of visibility over traffic flows makes managing firewall policies more difficult. Automation – Network firewalls have hundreds of security policies. Spread over multiple devices, manual management is difficult and time-consuming. Automation of network security management is the solution. Compliance – Proper configuration of your network security devices is a common regulatory requirement. Make sure you can demonstrate compliance. 1. Managing firewall configuration in a complex environment Since early networks were mostly on-premises, managing firewall configuration changes in real-time was simple. Once the cybersecurity team identified firewall changes they wanted to make, a single employee could upload those changes to the organization’s Cisco PIX device and call it a day. Today’s networks simply don’t work that way. They are designed to be scalable, supporting a wide range of endpoint devices and cloud-based applications with a much wider attack surface than ever before. Security teams must protect their networks against a more sophisticated set of attacks, including malware that leverages zero-day vulnerabilities and other unknown threats. At the same time, they must accommodate both users and attackers equipped with modern security tools like VPNs. The modern organization must deploy a wide range of firewalls, including hardware devices physically connected to local routers, software firewalls for hybrid cloud environments, and next-generation firewalls equipped with analyzers that can proactively detect unknown threats. Security leaders need to streamline visibility into firewall configuration, orchestration, and management through a single pane of glass. This ensures optimal firewall performance for both on-premises and cloud security solutions, while freeing team members to spend more time on higher impact strategic security goals. 2. Firewall deployments can compromise visibility into security processes Modern organizations with complex network configurations often don’t enjoy deep visibility into their security processes and event outcomes. Many third-party managed security vendors don’t offer in-depth data about their processes at all. Security leaders are often asked to simply trust that vendors provide enough value to justify premium pricing. But losing visibility into security processes makes it extremely challenging to improve those processes. It puts security leaders in the uncomfortable position of defending security outcomes they don’t have adequate data to explain. In the event of a negative outcome, it’s almost impossible to explain exactly what went wrong and why. If a particular firewall policy is ultimately responsible for that outcome, security leaders need to know. Effective firewall security management isn’t possible without deep visibility into firewall policies, and how those rules impact day-to-day business operations in real-time. Obtaining this kind of visibility in a complex network environment is not easy, but it’s vital to long-term success. 3. Manual configuration changes are costly and error-prone Increasing configuration errors are another knock-on consequence of the trend towards bigger and more complex networks. Where early network security professionals only had to update firewall rules for a handful of devices, now they must accommodate an entire stack of solutions made by different manufacturers, with complicated interdependencies between them. Most organizations rely on multiple providers for their full firewall stack. They may use Cisco hardware, Checkpoint next-generation firewalls, Tufin firewall management software, and Firemon asset management all at the same time. Managing and troubleshooting this kind of deployment without comprehensive firewall security management software is difficult and time-consuming. Security misconfigurations as a whole are responsible for more than one-third of all cyberattacks. This demonstrates the urgent need for security leaders to automate the process of configuring, updating, and validating firewall changes on complex networks. AlgoSec provides security leaders with a robust set of tools for automating network security policy updates and firewall changes without requiring organizations to dedicate additional employee-hours to time-consuming manual processes. 4. Don’t forget to document policy changes for compliance Security policy management is an important part of overall security compliance. Adhering to the latest security standards published by reputable organizations allows security leaders to meaningfully reduce cybersecurity risk. Documents like the NIST Cybersecurity Framework provide clear guidance into how organizations should address core functions in their security strategy, which includes deploying and updating firewalls. In particular, NIST Special Publication 800-41 describes the guidelines for firewall policies, requiring that they be based on comprehensive risk assessment for the organization in question. The guidelines also require that organizations with multiple firewalls sharing the same rules (or common subsets of rules) must have those rules synchronized across those firewalls. Importantly, all these changes must be documented. This requirement adds significant risk and complexity to network environments that rely on manual configuration processes. Even if you successfully implement changes the right way, reporting discrepancies can negatively impact your organization’s regulatory position. AlgoSec generates compliance reports for NIST SP 800-53 as a built-in feature, available right out of the box. Organizations that use AlgoSec to automate firewall security management and policy changes can ensure compliance with stringent security standards without having to commit valuable security resources to manually verifying reports. Schedule a Demo Firewall security management FAQs Understanding the network security devices in your network is crucial to maintaining your network’s security. What are some common network security devices? Network security devices include application and network firewalls, which are the most popular network security devices. However, your network may have other devices such as intrusion detection and protection systems, antivirus scanning devices, content filtering devices, as well as pen testing devices, and vulnerability assessment appliances. What is an application firewall? An application firewall controls access from an application or service, monitoring or blocking the system service calls that do not meet the firewall’s configured policy. The application firewall is typically built to control network traffic up to the application layer. What is a firewall device and how do firewalls work? A firewall is a network security device that monitors network traffic and decides whether to allow or deny traffic flows based on a defined set of security rules. Firewalls can be physical hardware devices, software, or both. What is network security management? Network security management lets network administrators manage their network, whether on-premises, in the cloud, or a hybrid network, consisting of physical and virtual single and multi-vendor firewalls. What are some challenges in network security management? Network administrators need to get clear and comprehensive visibility into network behavior, automate single and multi-vendor device configuration, enforce global network security policies, view network traffic, and generate audit-ready compliance reports across their entire network. Network administrators must continuously deploy security policies across the network. Yet, there may be thousands of firewall policies accumulated over the years. Frequently, they are cluttered, duplicated, outdated, or conflict with new rules. This can adversely affect the network’s security and performance.
