Firewall Rule Analysis & Optimization



Firewall rules can become massively complicated over time. As new applications, devices, and users are constantly provisioned and removed in networks to meet changing business demands, new rules are applied to firewalls. Also, as cybercriminals use different techniques and access paths, security teams constantly demand changes and updates on firewall policies. This intense and ever-active process can result in overpopulated rule sets. Over time, these rule sets tend to become duplicated, redundant, outdated, too generic, or non-compliant.

Rule Analysis & Optimization

Regular rule analysis and optimization are a crucial aspect of firewall management to ensure that rule sets are effective in delivering intended business and security outcomes and do not over-consume computing resources.Nevertheless, analyzing and optimizing rules can be a tedious task. Relying on spreadsheets is both labor-intensive and ineffective. Teams require an intelligent and lightweight solution to effectively address this crucial need in both small and large networks.

Rule Analysis & Optimization with Opinnate

The Opinnate platform enables IT teams to;

  • visualize all access policies and rules across
    their firewall estates – being whether on-premise, on the cloud, or both – on a single pane view
  • keep track of the shadowed, expired, duplicate, conflicting and permissive rules.
  • apply complex queries using granular search and filtering capabilities. 
  • visualise network topology with the context of rules and communication paths.
  • visualise objects and group objects.
  • generate operational, executive level and regulatory reports.

Rule Optimization with Opinnate

Opinnate greatly simplifies the optimization process. Using Opinnate,

  • operation teams gain flexibility by acquiring the capability of easily taking actions on unused, shadowed, expired, and disabled rules.
  • automate
    actions can be defined when unused, shadowed, expired, disabled are
  • IP
    addresses belonging to decommissioned servers can be quickly removed.
  • reordering
    and consolidation get easy to implement. 
  • permissive
    rules and those involving risky services can be efficiently addressed.
  • server
    and disk size for permissive rule optimisation is reduced up to 90%.
  • the
    risk of human error, configuration drift, policy inconsistencies is
    minimised, and version control and upgrades are simplified.
