Fortunately, a solution is available in the form of automated patch management, which uses various tools and techniques to streamline the patching process at scale. This article will guide you through the basics of setting up automated patch management in your organization, as well as explaining how it works, its benefits and challenges, and providing a few recommended solutions to help you get started.

What is automatic patching?

Automatic patching is an IT management practice that employs specialized software tools to streamline the detection, download, testing, and deployment of updates and patches to software, operating systems, and other system vulnerabilities. It primarily aims to enhance system security by addressing known vulnerabilities as soon as they are discovered.

Automatic patching reduces the workload on IT teams by eliminating the need for manual tracking and deployment of software patches and updates.

Automatic vs. manual patching

Automatic patching involves the use of automated tools and processes to deploy updates and security patches. Manual patching, on the other hand, requires human intervention to initiate, download, and install software updates and patches.

The following table compares automatic and manual patching:

How automated patch management works

When you deploy an automated patch management tool, the initial step is usually to scan the target environment for systems and applications that require updates and then deploy updates automatically, either when they become available or at predetermined rules or schedules.

Let’s consider an organization that uses an automated patch management system for its network of computers. The system, at predetermined intervals, scans all the computers in the network to identify outdated or vulnerable software.

When a critical security patch becomes available from a trusted source, the patch management system automatically downloads it and tests it on some of the computers to be sure the new updates don’t wreak havoc on any applications.

If the testing goes well, the patch is deployed across all the computers in the network during a maintenance window, usually set by the organization’s IT or system administrators for a time outside of normal business hours.

How to automate patching for your network

In order to automate patch management at your organization, you’ll need to select an effective tool, configure its settings, establish redundancies, audit and report on results, and continuously monitor your processes.

1. Select an automated patch management tool

The first step is, of course, to choose the automated patch management tool you want to go with for your devices. There are a few choices to get you started at the bottom of this article, or you can read our complete guide to the best patch management solutions for more advice on how to make the right selection for your particular use case.

2. Configure your settings

Once you’ve set up your patch management tool, it’s time to determine the settings that will guide your automations. These include:

• Patch sources: Indicate the sources you will want to receive patches from, including your operating systems, software, apps, and hardware. Ensure thorough scanning for missing patches and updates, as certain software vendors may not offer easily accessible patch information for automated tools. If needed, manually visit the vendor’s website to verify patch availability.
• Scan schedule: Determine how often you want the tool to scan the network for new patches for each of your software and hardware groups, and schedule the scans accordingly.
• Test groups: Name a few particular devices of each type to test each patch before deploying to the rest of the organization. This step is vital because patching can sometimes introduce compatibility issues with existing software. Test the patches in a safe environment (i.e., isolated systems) to ensure it is compatible with your current network setup.
• Maintenance windows: Decide what time patches will be deployed in order to minimize any disruptions or downtime.
• Prioritization levels: Assess system criticality and importance before patch deployment. Prioritize based on business needs and have a rollback plan ready in case of unexpected issues.

3. Establish redundancy and failover systems

Implement redundancy and failover for critical systems to provide backup in case of patching issues. This allows continuous operation of the software during problem resolution.

Although your test groups should catch any issues before they make it to this stage, delayed onset of failures and vulnerabilities is always possible — and in any case, when it comes to your data you can never be too careful.

4. Audit and report statuses and results

Automation can save your team a ton of time and effort, but it’s still not a fix-it-and-forget-it process. You’ll need to maintain detailed records of the patch management process, including patch type, application dates, and targeted systems. These reports aid in compliance and troubleshooting patch-related problems.

Many patch management solutions will create this documentation for you, but it’s still important to double-check it manually after each deployment to ensure all relevant information is present and accurate.

5. Monitor processes continually

Finally, you’ll want to keep an eye on all your automated patches, your settings, and those audits and reports that you’re keeping. If anything seems out of the ordinary, investigate immediately and thoroughly. Even if things seem to be going smoothly, regularly look for opportunities to tweak and streamline your settings for improved performance as you go.

Benefits of automating patch management

Automating patch management offers various benefits for organizations seeking to enhance their system security, from improved security and maintenance to reduced costs and response times.

• Enhanced security posture: Delayed vulnerability patching increases the risk of cyberattack. Automating patch management enhances an organization’s overall network security by reducing the risk of security breaches and data loss due to outdated systems.
• Simplified network maintenance: Automated patch management simplifies what can be an extremely complex and time-consuming network management task. This not only eases the administrative burden but also minimizes the chances of human error.
• Quick response to emerging threats: Automated patch management systems can promptly detect and deploy patches as they become available. This agility empowers organizations to quickly counter emerging cyberthreats and stay ahead of the evolving cybersecurity environment.
• Cost efficiency: Automating patch management cuts costs by reducing manual work and potential security incident expenses, not to mention the reputational hit from a data breach.

Common issues when automating patching

While the benefits of automating patch management are plentiful, there are some challenges that can’t be overlooked, including compatibility issues, bandwidth use, 

• Compatibility issues: Patches can sometimes conflict with existing software configurations and lead to system instability. Companies should invest in patch management solutions that offer comprehensive compatibility testing and provide detailed reports on potential conflicts.
• Bandwidth and network impact: When running patch scans, downloads, and deployment automatically across many systems, it can strain network bandwidth and cause disruptions. This can slow down essential business operations and impact user experience, unless you are careful to schedule these processes for off-hours.
• Security tool integration: Integrating patch management software with existing security tools involves complex configurations and compatibility between different security tools. As a result, organizations may face difficulties aligning these processes with their broader security strategies.
• Dealing with legacy systems: Some organizations still rely on their old, legacy systems and applications. Automating security patches on these systems can be challenging, as vendors often discontinue support for older software.

Who should automate patch management?

Automating patch management is recommended for organizations of all sizes and across various industries. It helps maintain IT systems’ security, stability, and compliance and reduces the risk of data breaches and cyberattacks.

However, the specific tools and processes for patch management may vary depending on the organization’s size, industry, and regulatory requirements. The larger and more complex the organization, the more critical an effective automated patch management system becomes.

While implementing microsegmentation may be complex, the rewards for heightened security and easier management are substantial. This guide will discuss the fundamental concepts, benefits, and best practices associated with microsegmentation in networking.

How microsegmentation works

Microsegmentation works by partitioning a network into smaller, self-contained segments known as microsegments. These segments act as individual security perimeters, which allow organizations to control and monitor network traffic between various components of their infrastructure. Microsegmentation can be broadly categorized into three main approaches:

• Agent-based microsegmentation: Involves installing software agents on network workloads to enforce segmentation policies.
• Network-based microsegmentation: Relies on network infrastructure components like switches, routers, and software-defined networking (SDN) to enforce segmentation policies.
• Native cloud microsegmentation: Integrates with cloud service providers like Google Cloud or AWS and utilizes their security features to enforce segmentation policies in cloud environments.

How is microsegmentation different from network segmentation?

Network segmentation, as a foundational concept, entails partitioning a network into subnetworks. This division is often based on criteria such as departmental distinctions, team boundaries, or even physical locations. It is typically achieved through the use of firewalls, routers, and Virtual Local Area Networks (VLANs).

Once an attacker is in, though, they can relatively easily move across the attack surface. If there is sensitive data present in a network segment, the data have not necessarily been separated from other data and likely do not have their own security protocols.

With microsegmentation, the data in the network is completely mapped out, categorized, and separated by level of importance and access needed. More specific security perimeters are applied to the most sensitive microsegments of data once they are identified, along with other safeguards like multi-factor authentication (MFA) requirements.

How is microsegmentation used in networking?

Microsegmentation is used in networking to enhance protection, control, and monitoring by dividing the network into smaller segments and applying specific access policies to each segment. It is also crucial in modern cloud and data center environments to provide granular control over network traffic, isolate security zones, and safeguard sensitive data from cyberthreats.

Benefits of microsegmentation

A recent report from Statista showed that over 80% of respondents from pioneering companies considered microsegmentation to have a significant impact on their zero-trust security strategy. The primary benefit highlighted was the improved operational efficiency and increased availability of security teams.

Here are some of the other benefits associated with microsegmentation:

Reduced vulnerability exposure

Microsegmentation decreases vulnerability exposure by isolating network segments. This makes it more challenging for attackers to move laterally within the network.

Reinforces regulatory adherence

Microsegmentation helps organizations meet regulatory compliance requirements. It helps ensure that sensitive data and systems are adequately protected and audited. This allows organizations to avoid fines and legal issues.

Streamlined policy administration

Microsegmentation simplifies policy administration by allowing organizations to define and enforce specific security rules for each network segment, rather than tracking and maintaining permissions for each individual user.

Common microsegmentation challenges

Microsegmentation presents some common implementation challenges, including infrastructure adaptation, process optimization, and integration with existing tools:

Infrastructure adaptation

Implementing microsegmentation often necessitates changes to an organization’s existing network infrastructure, requiring updates and potential investments in new technology to accommodate the segmented network architecture.

Process optimization

Organizations may face the challenge of re-evaluating and optimizing their network and security processes to align with the new microsegmentation strategy, which can be complex and resource-intensive, at least to begin.

Integration with existing tools

Integrating microsegmentation into existing network security tools and systems can be challenging, as compatibility issues and configuration adjustments may be required to ensure seamless operation and management.

What are the best practices for microsegmentation?

To ensure the effective deployment of microsegmentation, it’s essential to adhere to the following best practices:

Define boundaries carefully

Take the time to understand the data flows and dependencies within your network and then define the boundaries that will separate different parts of your network. When setting these boundaries, consider factors like business units, departments, and security zones. Precision in boundary definitions is essential for creating effective security policies.

Understand your applications

Understand how different applications interact with each other. Group related applications together and create segments that align with their specific needs and security requirements. This approach simplifies policy management and ensures that security measures are tailored to the behavior of the applications.

Identify levels of access

Clearly define different levels of access based on roles and responsibilities within your organization. Implement the least privilege principle, where users and systems only have access to the resources necessary for their specific tasks.

Gradually implement segmentation

Start with a phased implementation and focus on sensitive areas first. This gradual approach allows you to fine-tune policies, identify and address issues, and learn from initial segments before expanding to other areas of the network.

Types of microsegmentation

Microsegmentation comprises various types, each designed to fulfill specific objectives. These include segmenting by application, user, tier, and environment.

Application segmentation

Application segmentation focuses on safeguarding sensitive data-handling applications by creating security perimeters and controlling access. It efficiently manages east-west traffic between network applications.

User segmentation

User segmentation restricts user access based on roles and group memberships. This ensures limited visibility and customized network resource access.

Tier-level segmentation

Tier-level segmentation isolates and protects different organizational tiers. This allows controlled communication between them, such as between the processing and data tiers, while limiting web server access.

Environmental segmentation

Environmental segmentation is vital for networks with diverse environments, like development, testing, production, and staging areas. It isolates these environments and limits inter-environment communication, preventing attackers from exploiting vulnerabilities across the network.

Firewalls vs. microsegmentation

Firewalls and microsegmentation both serve the purpose of enhancing network security. However, their approach to network security is different.

A firewall monitors and controls network traffic based on preset rules. It creates a barrier between trusted internal networks and untrusted external networks to prevent unauthorized access and protect against cyberthreats. Top firewall software options include Norton, Fortinet, and pfSense.

Microsegmentation focuses on securing traffic within the internal network. It enforces security policies based on application awareness, user identity, and specific workload attributes.

In other words, both firewalls and microsegmentation are important elements in an enterprise’s overall network security stack; one does not cancel the other out.

Bottom line: Microsegmentation boosts security and management of enterprise networks

Microsegmentation is an effective strategy that strengthens network security by focusing on precision and control within a network. It is also a vital component of a broader zero-trust architecture initiative. While implementation may pose certain challenges, the rewards of improved security and control make it a worthwhile investment for any medium or large enterprise network.

The SD-WAN market is expected to hit $13.7 billion by 2026, with large enterprises constituting the highest share of customers using SD-WAN.

While SD-WAN enables companies to lessen the constraints of traditional WAN services and the inefficiencies that come with them, it is still riddled with some challenges. Here is a deep dive into some of these challenges and how you can address them.

Top SD-WAN challenges and issues

Some of the top challenges enterprises encounter when trying to deploy SD-WAN include picking the right vendor, issues with cloud connectivity, difficult troubleshooting, and security concerns. Here are some suggestions on how to deal with each of those problems.

Picking the right vendor 

Many organizations face the challenge of integrating the right SD-WAN solutions with their existing network infrastructure. Each vendor claims their product can revolutionize WAN services and bring about digital transformation in enterprises. Given this situation, it becomes more difficult to cut through the noise and select the right vendor. 

• To address this issue, IT teams should understand their network posture in order to determine which vendor can best deliver the required services.
• Efforts should be made to conduct thorough research into the top SD-WAN providers and vendors in the market to understand their service offerings and how they fit the bill.

Cloud connectivity issues

Cloud connectivity can be an issue in SD-WAN, especially when organizations have multiple cloud-based applications and services that need reliable and efficient access. Many traditional WAN architectures might not be optimized for direct cloud connectivity, and this often leads to performance bottlenecks, increased latency, and potential data security concerns.

• To resolve this issue and improve cloud connectivity in SD-WAN, organizations should implement SD-WAN solutions that have application-aware routing capabilities for intelligent routing decisions based on the specific needs of different cloud applications.
• Configure WAN policies for Dynamic Path Selection (DPS). This helps to automatically select the best path for cloud-bound traffic based on real-time conditions, such as available bandwidth, latency level, and packet loss.

Difficult troubleshooting

Troubleshooting in SD-WAN is very challenging due to its complex configurations. For instance, if a user is experiencing lag and slowness in an application, it’s difficult to pinpoint whether the cause is network-related, fault in deployment, lack of system resources, or something else.

Moreover, different vendors offer SD-WAN solutions with varying architectures, making troubleshooting vendor-specific implementations an issue. Distinguishing between application-specific performance problems and underlying network issues further complicates the process.

• To address this, try to install monitoring agents in all your network locations, as this will help collect the data you need to troubleshoot your SD-WAN network.
• Go for an SD-WAN provider that offers centralized management and configuration.
• Develop and follow standardized troubleshooting procedures for different types of issues.

Security concerns

There is a concern about the potential loss of visibility in SD-WAN due to its dynamically distributed traffic. This dynamic nature and the need for direct internet access at branch locations can create security vulnerabilities if not properly configured and monitored.

• One of the ways to address this challenge is to deploy SD-WAN alongside a secure access service edge (SASE).
• Employ network segmentation to separate critical assets and sensitive data from the rest of the network.
•  IT teams should consider only SD-WAN solutions with adequate endpoint security and configuration features.
• Deploy a packet-filtering firewall to filter network traffic and block any packets that carry malicious files or code.

General best practices for addressing SD-WAN issues

To ensure the smooth running of SD-WAN, it is essential to follow some general best practices that can address potential issues. These include conducting network evaluations, initiating a pilot deployment, taking a security-first approach, and continually monitoring and analyzing the results.

Conduct network evaluation

Before deploying SD-WAN, carry out a thorough assessment of your existing network infrastructure. Things like bandwidth requirements, application performance needs, and traffic patterns should be thoroughly checked to ensure the optimal performance of the SD-WAN.

Conducting this assessment will help you design a customized SD-WAN solution that meets your organization’s specific needs and addresses potential bottlenecks.

Consider a pilot deployment

Consider starting with a pilot deployment of SD-WAN in a limited number of locations before implementing it across the entire network. This allows you to test the solution in a controlled environment, identify any unforeseen challenges, and make necessary adjustments before scaling up.

Security-first approach

Integrate security measures into your SD-WAN deployment from the outset. Ensure that the selected SD-WAN solution offers robust security features and supports integration with your existing security infrastructure to ensure efficient network security. Prioritize end-to-end encryption and implement security policies consistently across all sites.

Continuous monitoring and analytics

Deploy network monitoring and analytics tools to gain real-time visibility into your SD-WAN performance. By monitoring key metrics, such as latency, bandwidth utilization, and application performance, you can proactively identify and resolve issues before they impact user experience.

Evaluate vendors critically

Conduct a thorough evaluation of various SD-WAN providers and vendors and their offerings. Choose a reputable vendor with a track record of successful deployments, excellent customer support, and a commitment to standards compliance.

Bottom line: Addressing SD-WAN challenges

SD-WAN is undoubtedly a transformative technology that offers numerous benefits to an organization’s network infrastructure. However, addressing the challenges associated with the solution is essential to ensure a successful SD-WAN deployment and experience.

To address the challenges, organizations should be strategic in choosing the right SD-WAN vendor, and pay attention to their capabilities before investing in the solution.

While traditional methods relied heavily on virtual private networks (VPNs) for remote connectivity, a growing trend towards zero trust network access (ZTNA) solutions is reshaping the landscape of secure network access. While both ZTNA and VPNs offer secure remote access, they differ in various aspects, making them suitable for different use cases.

So, which of these network access methods should you go for? This comparison piece will help you find out.

• VPNs: Best for providing versatile remote access to corporate resources and enabling connectivity across multiple locations.
• ZTNA: Best for implementing a zero-trust security model with granular access controls that ensure enhanced security for organizations prioritizing data protection.

What’s the difference between ZTNA and VPNs?

ZTNA provides individualized access to specific organizational resources, while VPNs grant remote users access to an entire network. To help you understand their differences, here is a quick comparison chart summarizing the key features.

What is a virtual private network (VPN)?

A VPN is a security solution that establishes a secure connection between the user’s device and the corporate network over the public internet. It creates an encrypted tunnel that protects data transmission from unauthorized access and interception.

VPNs have been widely used to provide versatile remote access, allowing employees to connect to their organization’s resources from anywhere, even outside the office premises.

Advantages of VPNs

• Versatile remote access: VPNs allow users to securely connect to corporate resources from anywhere.
• Enhanced privacy: VPNs encrypt data, protecting it from unauthorized access.
• Network-wide access: Users can access resources across the entire corporate network.
• Compatibility: VPNs work on various devices and operating systems.

Disadvantages of VPNs

• Trust-based model: Once inside the network, users are trusted to access any resources they encounter, which can present a security risk.
• Network performance impact: VPNs can introduce latency and reduce network speeds.
• Full network visibility: Users have visibility into the entire network, potentially exposing sensitive components.

What is zero trust network access (ZTNA)?

ZTNA is a security framework that focuses on maintaining strict access controls based on user identity and other contextual factors. Instead of granting network-wide access, ZTNA follows the principle of “verify first, access later.”

ZTNA represents a more modern approach to network security and operates under a zero trust model, where user access is granted on a per-session and per-application basis. Instead of relying solely on network perimeter security like VPNs, ZTNA emphasizes identity-based authentication, granular access controls, and continuous monitoring.

This approach aims to minimize the attack surface and mitigate potential risks by only granting access to authorized users based on their identity, device health, and other parameters, such as time of access, device type, and network conditions.

Advantages of ZTNA

• Zero trust security: ZTNA follows a strict authentication and access control model, reducing the attack surface.
• Granular access control: ZTNA allows for fine-grained access based on user identity and several other parameters.
• Reduced exposure: Users only see and access the specific resources they need.
• Compliance readiness: ZTNA helps organizations meet regulatory requirements with strong access controls.

Disadvantages of ZTNA

• Implementation complexity: Setting up ZTNA requires configuration and integration efforts, especially in complex environments.
• Scalability challenges: Scaling ZTNA for diverse access scenarios can be complex.
• Identity management dependency: ZTNA heavily relies on identity management systems for accurate user authentication.
• Impact on user experience: ZTNA may affect user experience and increase frustration due to additional authentication steps and checks.
• Cost: ZTNA adoption can be costly, especially for organizations with limited budgets.

Who should use ZTNA vs. VPNs?

Both ZTNA and VPNs offer great security options. The answer to which one you should go for at your organization depends on your specific budget, needs, and infrastructure.

Who should use ZTNA?

• ZTNA is a great option for enterprises with a lot of critical data and applications that require user-centric access controls — and have the IT resources to support them.
• ZTNA’s identity-based authentication and granular access controls make it an excellent choice for companies with distinct user groups using different apps and resources.
• If your employees primarily work remotely and require secure access to specific resources, ZTNA provides a more tailored and secure solution.

Who should use VPNs?

• VPNs offer network-wide access, making them suitable for companies with multiple departments and sites that need seamless connectivity across the entire network.
• If you have a lot of remote employees who need access to a wide range of resources and services across the network, VPNs allow for unrestricted access.
• VPNs are a great option for smaller businesses with few employees, since they’re easy to set up and scale with your business.

ZTNA and VPN: You don’t have to choose

While choosing either a VPN or ZTNA to protect your business’s network will be sufficient for many organizations, those looking to take the next step in network security may want to combine the two solutions. 

Companies like Array Networks offer SSL VPNs based on zero trust principles, with granular controls so IT can secure access at the endpoint while providing specific, role-based permissions across the network. These sorts of dual solutions — also offered by ExpressVPN and Fortinet, among others — are ideal for businesses with enterprise-wide remote access needs, or for cloud service providers looking to offer the widest range of access options for their customers.

As business security needs continue to grow both more complex and stringent, expect to see more of these combined ZTNA VPN solutions appearing on the market.

Bottom line: Choosing between VPN and ZTNA for your network

Understanding the differences between ZTNA and VPNs is crucial before making any decisions about switching.

While VPNs have been around for many years, ZTNA represents a modern security approach under the zero trust model. ZTNA’s emphasis on identity-based authentication, granular access controls, and limited network visibility can significantly enhance security, minimize the attack surface, and better protect against evolving cyber threats.

Although both solutions have their merits, ZTNA stands out for organizations that prioritize robust security and have a lot of sensitive data to deal with. On the other hand, a VPN is ideal for organizations with less sensitive data and lower security risks, as well as organizations that want to provide full network access to their remote users.

Whichever solution you choose to go with, we’ve got you covered: read our guide to the best VPN services and the best ZTNA solutions available today.

1. Implement a firewall

A firewall acts as a barrier between your network and the outside world, as it monitors incoming and outgoing network traffic. Deploying a firewall will enable your organization to filter and block unauthorized access attempts.

By defining strict rules for the firewall, you can control the types of traffic allowed into your network, reducing the risk of malicious intrusions.

Implementing a firewall also involves regular firewall audits to ensure it remains effective. This can be achieved using firewall audit software, which can automatically review, analyze, and signal potential weaknesses in firewalls.

2. Use strong passwords

One of the simplest ways to enhance network security is by using strong passwords. Weak passwords are vulnerable to brute-force attacks and can be easily cracked by malicious actors.

Implement a password policy across your organization that enforces complex passwords containing a combination of uppercase and lowercase letters, numbers, and special characters. Additionally, encourage regular password updates to prevent unauthorized access.

A password management service can help enforce better password hygiene across the organization.

3. Enable two-factor authentication (2FA)

In addition to enforcing a strong password policy, organizations should implement 2FA wherever possible. Also known as multifactor authentication (MFA), 2FA provides an extra layer of security by requiring users to provide two forms of identification to access the network.

By enabling 2FA or MFA, even if passwords are compromised, unauthorized access can be significantly mitigated.

4. Regularly update software and firmware

Software and firmware updates often contain patches and security fixes that address vulnerabilities in the system. Regularly update all network devices, including routers, switches, firewalls, and servers, with the latest security patches.

However, setting up a firewall can be daunting for many organizations as the constantly evolving cybersecurity landscape often leaves them unsure of where to begin.

In this guide, we’ll unravel how to set up a firewall and some critical factors to consider while doing so.

Components involved in firewall configuration

Configuring a firewall involves various components—from hardware and software to documentation and rules—that work together to create a robust security posture.

Firewall hardware

The hardware component of a firewall refers to the physical device responsible for filtering network traffic. It typically includes specialized processors, memory, ports, and network interfaces.

Firewall hardware can range from standalone appliances to integrated devices such as routers and switches with built-in firewall capabilities. Sorting out the right hardware is crucial, as it determines factors like performance, scalability, and additional features.

Vendors like Cisco, Juniper, and Fortinet provide reliable and robust firewall solutions.

Firewall software

Firewall software comprises the operating system (OS) and associated applications installed on (or acting in place of) the firewall hardware. It provides the necessary tools and interfaces to configure and manage the firewall.

The software enables administrators to define firewall rules, access control policies, and manage other security parameters.

Operating system (OS)

You’ll need an OS on which the firewall software can run, especially if you use a software-based firewall. This could be a general-purpose operating system like Linux or a specialized firewall-focused one like pfSense or Cisco.

Network interfaces 

Network interfaces facilitate the firewall’s connection to your network and enable network traffic monitoring. They can be integrated into the firewall hardware or on the server running the firewall software.

The number of interfaces needed will depend on your network architecture and the level of segmentation and control you aim to achieve.

Firewall rules

You must define firewall rules that specify what traffic should be allowed or blocked. This involves understanding your network’s security needs and developing well-designed rule sets that effectively enforce policies such as default deny, allowlisting and blocklisting, content filtering, intrusion prevention, and VPN enforcement.

Network diagram and documentation

A network diagram outlining your network infrastructure is crucial for understanding your network’s layout, identifying potential security risks and conducting an effective firewall audit. It visually represents how different components are connected, helping you design and implement effective firewall rules.

It is also essential to document the configuration and rules of your firewall. This helps to understand the firewall’s setup and allows for easier troubleshooting and maintenance.

Steps to configure a firewall

Configuring a firewall involves several steps to ensure its proper setup and functionality, from initial securing to testing. Here are the steps typically involved in the firewall configuration process.

Step 1: Secure the firewall

Securing a firewall ensures that only authorized administrators can access it. This involves several elements:

• Keeping the firewall updated with the latest firmware.
• Implementing appropriate configurations before deploying firewalls into production.
• Disabling default accounts and changing default passwords to prevent unauthorized access attempts.
• Using strong passwords to enhance the security of administrator accounts.
• Avoiding the use of shared user accounts. In cases where multiple administrators manage a firewall, it is crucial to establish additional admin accounts with restricted privileges based on individual responsibilities.
• Simple Network Management Protocol (SNMP), which gathers and organizes information about devices on IP networks, should be either deactivated or set up to prevent potential security breaches.
• Enforcing outgoing and incoming network traffic restrictions for targeted applications. This helps control and regulate the data flow, reducing the risk of unauthorized access or data breaches.

Step 2: Establish IP address structure and firewall zones

To protect network assets and resources, it is essential to identify them and establish a structured approach. This involves grouping corporate assets into zones based on their functions and the level of risk they pose.

An excellent illustration of this practice is segregating servers, such as email, VPN, and web servers, into a dedicated demilitarized zone (DMZ). The DMZ limits inbound internet traffic, bolstering security measures. Creating multiple zones within the network enhances network security, allowing for better traffic control and management. 

Once a network zone structure is established, aligning it with an appropriate IP address structure is crucial. This ensures that zones are correctly assigned to firewall interfaces and subinterfaces, enabling effective traffic monitoring and control.

Step 3: Configure Access Control Lists (ACLs)

ACLs play a vital role in network security by enabling organizations to regulate traffic flow between zones. ACLs should be configured with precision, specifying source and destination port numbers and IP addresses. Implementing a “deny all” rule at the end of each ACL ensures that unauthorized traffic is filtered out. 

Furthermore, each interface and subinterface should have inbound and outbound ACLs to authorize only approved traffic. To safeguard configuration and prevent unauthorized access, it is recommended to restrict public access to firewall administration interfaces and turn off unencrypted firewall management protocols.

Step 4: Configure other firewall services and logging

Firewalls can be configured to accommodate additional services, including:

• Dynamic Host Configuration Protocol (DHCP): A network server that automatically assigns and manages IP addresses to a network device, allowing them to communicate and access network resources.
• Intrusion Prevention System (IPS): A security technology that monitors network traffic for malicious activities and takes preventive actions to block or mitigate potential threats, such as malware or network-based attacks.
• Network Time Protocol (NTP) server: A network server that synchronizes the time across devices and systems in a network, ensuring accurate timekeeping and coordination.

Step 5: Test the firewall configuration

Conduct thorough testing to verify that the firewall functions as intended. Testing helps identify any vulnerabilities or misconfigurations that may expose your system to potential threats. 

The firewall setup testing can include things like network segmentation controls, rule verification, and logging and monitoring review.

What to watch out for when setting up a firewall

When setting up a firewall, there are several important factors to watch out for to ensure adequate network security, including your firewall type, logging and monitoring systems, and implementing a disaster recovery plan.

Firewall types

Choose the appropriate type of firewall based on your network requirements. Common types include packet-filtering firewalls, stateful inspection firewalls, and proxies with advanced features like intrusion detection and prevention.

Logging and monitoring

Configure firewall logging to capture comprehensive data on network traffic and connection attempts. Also, establish a centralized logging system to gather and examine the firewall logs effectively.

Access control

Implement robust authentication mechanisms and restrict administrative access to authorized personnel only.

Disaster recovery plan

In the event of a firewall failure or misconfiguration, it’s important to have a disaster recovery plan in place. Regularly back up your firewall configurations and ensure you have a documented procedure for restoring the firewall to a functional state.

Regular updates

Regularly review and update access control lists and user privileges to maintain security. Also, stay updated with the latest firmware, software patches, and security updates the firewall vendor provides. This addresses any newly discovered vulnerabilities and reduces the risk of unauthorized access or exploitation.

Bottom line: Configuring your firewall

Firewalls are essential in securing and protecting your network from unauthorized access and potential threats. Following the steps to firewall configuration outlined in this guide, you can establish a robust defense mechanism for your system and safeguard sensitive data, preserve network privacy, and reduce potential risks, ultimately ensuring a secure and resilient network environment for your organization.

Once your firewall is all set up, don’t forget to perform regular firewall audits.
