Firewalls play a critical role in enterprise network security, and firewall policies dictate the efficiency of the network security infrastructure. This is why it's crucial to get your firewall policies right. However, enterprises typically have hundreds of firewall rules and multiple security admins working on firewall policies. In these instances, firewall rules often run into the following challenges:
This is why it's important to have a firewall management policy tool that can identify rule anomalies and suggest rule changes, which can help reduce overly permissive rules. Firewall Analyzer is end-to-end rule management software for your firewall that can help optimize firewall policies by providing in-depth visibility into your rule interactions. Below are the policy optimization reports Firewall Analyzer generates.
Firewall Analyzer identifies and generates detailed reports on various rule anomalies such as shadow, redundancy, generalization, correlation, and grouping. These anomalies negatively impact the performance of the firewall, and removing them will help you optimize your firewall rules.
A smart firewall policy strategy requires reduced use of overly permissive rules, as these rules can be exploited by hackers to get into the network. Firewall Analyzer does not only identify overly permissive rules, but also suggests how to reduce these rules.
Similar to overly permissive rules, any rule linked to "any" or "all" services poses a threat to the network. Firewall Analyzer can identify these permissive services for a specific rule and suggest appropriate changes to the rule. With this report you also get a list of used and unused objects linked to a specific rule, so you can further fine-tune your rules by removing the unused objects.
With these reports, Firewall Analyzer helps security admins optimize firewall policies in their network security infrastructure. Download a free trial of Firewall Analyzer, and get the best out of your network security infrastructure.
