Firewall Configuration Security Review

Firewall Configuration Security Review

Firewall Security Reviews evaluate how effectively network security rules are designed and implemented. Students learn real firewall rule analysis, segmentation logic, and how misconfigurations lead to breaches.

For businesses, we deliver manual reviews with clear recommendations—not just automated scans. For students, these projects develop network security thinking, making them valuable for SOC, network security, and consulting roles.

Many organisations networks are configured to rely on strong perimeters; if your firewall is poorly configured then attackers may target services thought to be protected. Firewall reviews ensure that the device and its ruleset are properly hardened.

Firewalls are a primary line of defence for many organisations, therefore ensuring they are as hardened as possible is critical. Our Firewall Security Reviews cover the following security issues:

  • Overly permissive rules
  • Unintentionally exposed services
  • Insecure cryptographic options
  • Default credentials
  • Default services enabled, e.g. SNMP
  • Exposed administrative interfaces
Whilst the process of locking down a ruleset to only the minimum rules necessary seems simple on the face of it; things sometimes go wrong. With test rules accidentally left in place, rules being configured to be broader than intended, or just changes made over time leading to a looser ruleset than desired. An independent firewall configuraiton security review will help tighten things back up.
