Firewall Change Management Software is a critical part of the overall Security Operations Center (SOC) infrastructure and operations. It is essential to keep the firewalls secured and up to date, while considering production system dependencies and business continuity requirements. Best practices should be adopted at all times to ensure that the firewall change management process is efficient and effective, avoiding downtime that may result from misconfigurations or oversights during changes made to firewall rules and settings.

In this guide, we review the aspects of Firewall Change Management Software, firewall change management best practices, firewall change policy, and firewall management tools open source.

Firewall Change Management Software

The firewall change management software is an essential tool that helps you track the changes made to your firewall over time. It helps you identify the latest changes and ensure that nothing goes out of scope. The firewall change management software ensures that you have a good grip on what has been changed in your system and when it was changed, thus providing security and protection against any unauthorized access to data or applications on your network.

Can you indicate what a firewall change management software is?

A firewall change management software is a software that helps to track and manage changes made to the firewall rules. It also helps in making sure that the changes are carried out in an orderly manner. It can help to automate the process of applying changes and make it easier for you as well.

This is because a lot of time can be wasted when there are many people involved when making changes, especially if they require approval or other formalities before those changes can be applied.

Why is it important to have an effective firewall change management software?

A firewall change management software can help you to ensure that there is no unauthorized access to the network, that your system is secure and safe for users, that it isn’t vulnerable to attacks and that it will not be compromised in any way.

What is the role of a good firewall change management software?

A good firewall change management software is one that can help you implement the change management process. The change request, approval, implementation and monitoring processes are all a part of this.

It should be able to handle all kinds of changes including changes in functional components (feature upgrades) or non-functional components (bug fixes). It should also help you ensure that only authorized people make changes to your firewall configuration and software updates are rolled out properly.

How could one identify a good firewall change management software in the market today?

If you’re looking for a good firewalls change management software, it’s important to consider these factors:

  • The features of the software. What does it do? How does it work? It’s important that your firewall change management software is able to provide you with all of the necessary tools and features to achieve your objectives.
  • Customer reviews. Make sure that there are plenty of happy customers who have used this product before you made a decision in buying one yourself! You can check out their website and read what real people have said about them; if they’re not satisfied with their experience, then maybe there are ways where this could be improved through further development or innovation over time|>

firewall change management best practices

A network firewall is your most crucial security tool that must be as robust as it can get. Network firewall configuration can be a challenging task for administrators as they have to strike the perfect balance between security and speed of performance for the users.

Network firewall configuration must not only aim at protecting against external security threats but should also protect from malware that could exfiltrate sensitive data from your network to other locations. It is also important to protect the network from any prospective security threats in the future, rather than only concentrating on existing threats.

For network administrators, here is a list of seven firewall best practices to adopt to secure the network from any existing or potential threat:

Block traffic by default and monitor user access

It is advisable to block all traffic to the network by default. Allow only some specific traffic to certain known services. This helps you to have control over who can access your network and prevents any security breaches from occurring.

The firewall being your first layer of protection against threats, must not allow access to anyone and everyone to alter the configuration. User permission control is necessary to ensure that only authorized administrators have access to change firewall configurations. Apart from this, every time an authorized administrator does change any configuration, it must be recorded in the log for audits and compliance. Any unwarranted configuration changes can thus be detected, and configuration restore may be implemented in such a case.

You can also create separate user profiles to provide various levels of access to the IT staff, only as much as needed for a job. Firewall logs must be monitored regularly to detect any unauthorized break-ins to the firewall, from inside or outside the network.

Establish a firewall configuration change plan

Your network’s firewall will need to be updated from time to time for various reasons. This is necessary to ensure that the firewall remains strong and capable of protecting against new threats. But it is important to have a change management plan so that the process is smooth and secure. Any unplanned configuration change leaves a loophole in your network’s security.

A well-defined and robust firewall change management plan must include certain basic features:

It must define the changes that are required and their objectives.
It should also enlist the risks involved due to the policy changes, their impacts on the network, and a mitigation plan to minimize the risks.
A well-defined structure of change management workflow between various network teams.
Proper audit trails that record who made the change, why, and when.

Optimize the firewall rules of your network

The firewall rules must be well-defined and optimized to provide the expected protection. Cleaning up your firewall rule base of any kind of unnecessary clutter can have a positive impact on your network security.

Your firewall rule base may have certain redundant elements, duplicates, or bloated unnecessary rules that make the guidelines complicated and less effective. It is important to get rid of such rules to have a clear set of guidelines that can be followed better.

To clean your firewall rule base, you must:

Eliminate redundant or duplicate rules that slow down the firewall performance as they require the firewall to process more rules in its sequence than necessary.
Remove the rules that are obsolete or no longer in use. These only make the firewall management more complex, and can even be a threat to network security if not updated.
Remove shadowed rules that are not essential. These may lead to more critical rules being neglected.
Any errors or inaccuracies in the rules must be eliminated as these may result in malfunctions.
Remove the rules that are obsolete or no longer in use. These only make the firewall management more complex, and can even be a threat to network security if not updated.

Update your firewall software regularly

Firewall vendors usually release software updates regularly. These updates address any new potential security threats by making minor changes to the software. It is important to keep updating your firewall software to ensure that your network is secure, and there are no loopholes in the system that could pose a threat to security. You must check from time to time if your firewall software is updated to the latest version.

Conduct regular firewall security audits

Security audits are necessary to ensure that the firewall rules comply with the organizational, as well as external security regulations that apply to the network. Unauthorized firewall configuration changes that are a policy violation can cause non-compliance. It is important for administrators and IT security staff to carry out regular security audits to ensure no unauthorized changes have taken place.

This will also keep you updated on the necessary changes made to the firewall and warn you against any potential risks created by these changes. Security audits are most essential when there is a new firewall installed, firewall migration activity happening, or when there are bulk configuration changes made on firewalls.

Have a centralized management tool for multi-vendor firewalls

Multi-vendor firewalls are quite common in most organizations. Companies prefer firewalls manufactured by different companies installed in the systems to offer additional layers of security. But the challenge here is that the architecture of firewalls from different manufacturers is usually different.

It is important to manage all your firewalls centrally at one place to ensure they are all functioning properly. Using a multi-vendor firewall management tool allows you to have a unified view of firewall policies and rules, enabling you to compare and manage firewall rules easily. You can also perform security auditing and reporting, troubleshoot configuration issues, and provide support with a gap analysis for firewall migration through this centralized management tool.

Automate the process of firewall updating

With improvements in technology, many processes have become faster and easier. It may not always be possible for firewall administrators to constantly check for updates and perform software updates regularly. This leaves the network at risk of security breaches.

To avoid any lapse in updating your firewall, you can automate the process instead. An automated system can be scheduled to check for available updates and implement the updates when they find one. This reduces the need for human intervention and keeps the firewall secure and robust at all times.

firewall change policy

Firewall change management should be used before making changes to firewall or IDPS rules that affect users. A concrete firewall change management and firewall configuration monitoring process helps ensure complete cohesion in managing changes in your network.

How does Firewall Analyzer act as a firewall configuration management tool?

1. Firewall configuration change monitoring

Firewall Analyzer fetches the firewall configuration using CLI or API from your firewall devices and enables you to keep an eye on the changes being made to the network security infrastructure. Administrators may commit an unintentional error or carry out an improper change while acting on a firewall configuration change request giving room for breaches. This feature ensures that all the configurations and subsequent changes made in the Firewall device are captured periodically and stored in the database. Firewall Analyzer’s configuration change management reports precisely helps find out ‘who’ made ‘what’ changes, ‘when’ and ‘why’ to the firewall configuration.

Configuration change reports

The Firewall Change Management reports can be scheduled and distributed via Email and can be exported to different formats. Not only that, you can also filter the firewall configuration change management report for known and recurring changes which clutters the report. Firewall Analyzer will exclude the lines in the report, matching the specified criteria (Exclude Criteria) for all or selected devices.

2. Firewall configuration change alerts

Firewall Analyzer (Firewall Change Management Software) generates alerts for the Firewall device configuration changes in real-time and it notifies via Email, SMS. Hence any change made to the firewall configuration is notified to the security admin and this beneficial in effective firewall change monitoring.

Firewall change management

In any organization, frequent firewall changes are a necessity when it comes to network security. Putting into place a streamlined firewall change management policy template reduces management time and also the chance of introducing new security or compliance issues with each change. A typical firewall change management process would include the following steps:
