Firewall Rule Assessment - Why It's Important

Protect Your Business Network With a Firewall Rule Assessment.
Why Perform A Firewall Security Assessment?
A firewall is a crucial network security device that monitors and controls your network traffic based on predetermined security rules. It acts as a barrier, inspecting all traffic and blocking malicious traffic that could harm your network.
However, as technology and cyber threats evolve, your firewall rules may become outdated and unable to protect your business network from the latest threats in the current configuration. With that in mind, the following are a few of the reasons why you should perform a firewall security assessment:
| Assessment Area | What It Checks | Why It Matters |
|---|---|---|
| Rule Base Review | Active, unused, redundant, overly broad, or outdated rules | Improves performance, reduces attack surface |
| Traffic & Event Logs | Patterns, anomalies, unauthorized activity | Helps detect misconfigurations or threats |
| Access & Connection Controls | Ports, protocols, user access, remote connections | Ensures only approved traffic reaches your network |
| Change Management | How firewall updates and rule changes are handled | Prevents unauthorized changes and config drift |
| Physical & OS Security | Device placement, OS patches, hardening | Reduces risks from tampering or unpatched systems |
| Risk Scoring | Weak points, compliance gaps, exposed services | Prioritizes what must be fixed first |
| Rule Base Cleanup | Eliminating clutter and outdated rules | Simplifies management and reduces errors |
| Ongoing Review Plan | Frequency of future assessments | Keeps your firewall aligned with new threats |
Optimizes Firewall Rule Base
The firewall rule base is a set of rules that governs the behavior of the firewall. For example, your firewall rules can specify which types of traffic are allowed and which are blocked. A firewall assessment helps you assess the effectiveness of your existing firewall rules. It allows you to optimize them for maximum performance.
During an assessment, our team of experts will evaluate each rule and recommend changes that can help ensure your firewall is providing the highest levels of protection. We'll also identify any unnecessary rules that can be removed to reduce complexity and improve performance.
Protects Firewalls From Security Risks
A firewall rule assessment can help protect your firewall from security risks, such as blocking legitimate traffic, going offline, or being hacked. We'll examine the rules already in place and recommend changes to ensure they correctly identify and block malicious traffic while allowing legitimate connections.
We'll also review external threats, such as malware or attacks from compromised websites. By taking proactive steps to secure your firewall, you can protect against malicious actors and threats.
Identifies Vulnerabilities In Access And Connections
A firewall security assessment provides an in-depth look into possible vulnerabilities in access and connections. We'll inspect the protocols, ports, and other devices connected to your network and identify any potential weak points or misconfigurations.
Doing so helps ensure that only authorized users can access sensitive data and applications while restricting unauthorized access from outside sources.

Malicious traffic is any data or code intended to damage or disrupt your network. It can include viruses, malware, ransomware, and other unwanted traffic, such as spam and phishing emails.
By conducting regular firewall rule assessments, you can ensure that your network can protect itself from malicious traffic, even when existing rules are overwhelmed. Existing rules can be overtaken by unwanted traffic if they are too broad or don't take into account new threats.
At Hummingbird Networks, we can help you identify and address any security risks or vulnerabilities in your existing rule base. We provide efficient firewall assessments for businesses tailored to your specific needs and backed by decades of experience. By performing regular assessments, you can stay ahead of the latest threats and ensure your network remains secure.
Firewall Assessments For Small Businesses to Large Enterprises
Small businesses are particularly vulnerable to malicious traffic since they often have limited resources and personnel dedicated to network security. Unfortunately, this means that it can be easy for malicious actors to slip through the cracks. When this happens, it could cost the business significantly in terms of lost revenue and reputation damage.
Fortunately, there is no reason why these businesses can't take advantage of the same level of protection as large companies. With a firewall rule assessment from Hummingbird Networks, small-to-medium businesses can proactively help protect their networks from malicious actors and threats, thereby avoiding the costs associated with data loss.

How We At Hummingbird Networks Conduct Firewall Assessments
At Hummingbird Networks, we conduct comprehensive firewall assessments to ensure your rules are optimized for maximum performance and security. Our assessments cover the following areas:
Review Of All Firewall-Related Records
Firewall-related records refer to any information kept by the firewall that is related to its rules and configurations. These records can include network topology diagrams, traffic logs, access lists, and other essential details.
By conducting a thorough review of these records, we can ensure they accurately reflect the current state of your firewall and identify any potential vulnerabilities or misconfigurations. This ensures that the rules are properly implemented and configured to provide the highest levels of security.
Assessment Of Change Management Processes
Change management processes are the set of procedures and guidelines that allow organizations to control, plan, and implement changes in their IT systems. This includes the acceptance, assessment, authorization, implementation, and review of changes.
We'll assess your change management processes during our firewall assessment process to ensure they meet the necessary standards. This helps you maintain control over who can make changes, which processes are used to implement them, and when they should be reviewed. Doing so ensures that any new threats or vulnerabilities can be addressed immediately.
Assessment Of Physical And OS Security
We'll assess the physical and operating system security of your firewall. For example, we'll check to make sure that the firewall is installed correctly and protected against physical attacks, such as tampering or theft.
We'll also review the operating system to ensure all necessary patches and updates are applied. Doing so helps ensure that unauthorized users cannot access the device or change its settings without permission.
Decluttering Of The Rule Base
If the rule base is cluttered, it can lead to reduced performance and an increased risk of security threats. We'll declutter your rule base of any redundant or unused rules to help reduce the complexity and optimize performance. This helps to ensure that only essential rules are active, which can significantly improve the security posture of your network.
Risk Assessment
We'll perform a risk assessment to identify any potential weak points or misconfigurations in your existing rule base. For example, we can identify if any ports are open, which could allow malicious actors to gain access to your network.
We'll also review the rules in place to make sure they meet the requirements of external regulations and internal security policies. This helps you make informed decisions on which rules should be kept, updated, removed, or replaced.
Regular And Ongoing Assessment Process
Finally, we also recommend a regular and ongoing assessment process to ensure your firewall remains secure. This involves scheduling periodic reviews of your rule base to check for any new risks or vulnerabilities that may have emerged since the last assessment.
