Exam CISA topic 1 question 1080 discussion

Reviewing the rule base directly compares the firewall's configuration with the organization's security policy. The rule base contains the explicit rules that determine what traffic is allowed or denied by the firewall. By verifying these rules against the security policy, an auditor can ensure that the firewall is configured appropriately to enforce the required security controls.

The best audit evidence that a firewall is configured in compliance with the organization's security policy is reviewing the rule base. The rule base of a firewall contains the set of rules that dictate how traffic is allowed or denied through the firewall. By reviewing the rule base, an auditor can assess whether the configuration aligns with the organization's security policy, ensuring that only authorized traffic is permitted and unauthorized traffic is blocked.
