Maintaining Clean, Reliable and Secure Firewall Policies
As thousands of change requests are processed by the security team, the underlying policy configurations (firewall rulebases, router and switch ACLs) become very large and complex. Over time, firewall policies grow increasingly large and complex and often hide unnecessary connectivity that can be exploited during a security breach. In fact, many of the rules and objects in a typical firewall or router policy are obsolete. These unused rules represent a potential security risk and should be eliminated, yet it is nearly impossible for managers to locate them and remove them without risking business continuity.
A poorly managed policy is difficult to maintain and requires the attention of senior administrators with a great deal of expert, undocumented knowledge. Since a mistake can result in application or network downtime, it isn't feasible to assign policy management to less-experienced or outsourced staff. The potential cost of an error is even higher for security service providers.
In addition to security risks, a poorly maintained policy can have a major impact on performance. The entire rule base is parsed from top to bottom with every network connection, and as it grows, hardware requirements also increase. Security teams need automation in order to maintain secure, efficient policies on all of their firewalls and routers.

- Identify for cleanup unused rules, ACLs, network objects and group members
- Identify rules and objects that need to be optimized or removed such as shadowed rules, unattached objects, duplicate objects and services, empty groups and redundant and disabled rules and ACLs
- Identify overly permissive rules that need to be replaced
- Enforce compliance for industry regulations and enterprise policy best practices such as proper rule documentation, naming conventions, rule base structure, rule recertification policies etc.
- Analyze actual rule and object
- Identify and cleanup unused rules, ACLs, network objects and group members
- Identify rules and objects that need to be optimized or removed
