The first step in managing and protecting your network from malicious actors is to create a well-thought-out strategic plan. Today, the goal of every business’s security strategy is to continuously protect the network from attacks that can jeopardize the success or reputation of its business. Organizations that use the internet for email, web applications, or information sharing are great targets for ransomware, phishing, and other illicit cyber activity, to name a few, due to the global reach of the internet and the transition to a mobile workforce.
Network Security Management is essential and unquestionably a requirement for your business for all of these reasons and more.
Your most important security instrument, a network firewall, ought to be as strong as possible. Administrators may find it difficult to configure a network firewall because they must find the ideal balance between user performance and security. In addition to defending your network from external security threats, network firewall settings must also guard against malware that could leak critical data to other networks. Instead of just focusing on current attacks, it’s crucial to safeguard the network against any potential security risks in the future.
The management of the firewall by security and networking groups is listed below.
-
Block traffic, and keep an eye on user access.
The network should be configured to automatically block all traffic. Allow only a certain quantity of specific traffic to known services. This makes it easier to manage who has access to your network and guards against security lapses. Since the firewall is your first line of defense against attacks, no one should be able to access it or change its configuration. User permission management is required to guarantee that only authorized administrators can modify firewall configurations. In addition, any configuration change made by an authorized administrator must be noted in the system log for inspections and compliance. Thus, any unauthorized configuration modifications can be found, and a configuration restoration can be carried out when necessary.
Additionally, you can make distinct user profiles to grant the IT personnel with different levels of access—but just as much as is required for a particular task. Firefight logs must be frequently examined to identify any illegal firewall intrusions from the network’s interior or outside.
-
Create a plan for changing the firewall’s configuration.
The firewall on the network will occasionally need to be upgraded for a variety of reasons. This is required to maintain the firewall’s strength and ability to defend against evolving threats. But for the process to be secure and seamless, it’s crucial to have a change execution strategy. Any unforeseen configuration change creates a security gap in the network.
Some fundamental components of a thorough and well-defined firewall change management strategy must be present:
- It must specify the necessary adjustments as well as its goals.
- It should also include a summary of the risks associated with the policy modifications, their effects on the system, and a risk-mitigation strategy.
- A workflow for change management that is clearly specified among various network teams.
- Appropriate audit trails that document when, why, and who changed something.
-
Make your network’s firewall policies more effective.
For the firewall to offer the desired level of security, the rules should be well-specified and tuned. The network security may benefit from clearing the firewall rule base of any unnecessary clutter. Your firewall rule base can have some redundant components, duplicates, or bloated superfluous rules, which complicate the rules and reduce their effectiveness. In order to set a clear set of rules that can be better adhered to, it is crucial to get rid of these regulations.
You need to clear the firewall rule base.
- Reducing the number of identical or duplicate rules the firewall must process in its processing sequence will improve performance.
- Discard any rules that are no longer relevant or in effect. If not updated, these just complicate firewall operations and may even pose a risk to network security.
- Remove any unnecessary shadowed rules. These could result in the ignoring of more significant rules.
- The rules need to be accurate and error-free; else, faults may occur.
- Delete any regulations that are no longer relevant or in effect. If not updated, these serve to complicate firewall operations and may even pose a risk to network security.
-
Regularly update the firewall software.
Software updates from firewall companies are published frequently. These updates make modest modifications to the software in order to handle any new possible security issues. To make sure that the network is secure and that there are no flaws in the framework that could endanger security, it is crucial to update your firewall software regularly. You must periodically verify that your firewall software is running the most recent version.
-
Regularly do firewall security audits.
Security audits are required to ensure that the firewall rules adhere to the internal and external security standards that apply to the network. Non-compliance may result from unauthorized firewall configuration modifications that are against policy. Regular security audits are crucial for admins and IT security professionals to guarantee that no illegal changes have been made.
This also keeps you informed of any necessary firewall modifications and alerts you to any new dangers resulting from them. The need for security audits is most significant when a new firewall is deployed, when a firewall is being moved, or when firewall configuration modifications are made in bulk.
-
A consolidated control tool for firewalls from several vendors
Most enterprises frequently use multi-vendor firewalls. Vendors prefer installing firewalls made by various vendors in their systems to create additional security levels. However, the problem is that firewalls from different manufacturers typically have varied architectural designs.
To make sure they are all operating effectively, it is crucial to control all of the firewalls centrally in one location. You can easily compare and administer firewall rules if you use a multi-vendor firewall management solution that provides you with a unique view of firewall policies and rules. Through this centralized administration tool, you can also carry out security auditing and reporting, solve configuration problems, and offer assistance with a gap assessment for firewall migration.
-
Automate the update of firewalls.
Several processes have gotten quicker and simpler as a result of technological advancements. Firewall administrators may not always be able to regularly run software upgrades and check for updates all the time. As a result, the network is vulnerable to security flaws. You can systematize the process to avoid any errors when updating the firewall. It is possible to program an automated system to look for updates that are available and to apply them when one is discovered. As a result, there is less need for human intervention, and the firewall is always strong and secure.
