Vulnerability discussion

Auditing and logging are key components of any security architecture. Logging the actions of specific events provides a means to investigate an attack, recognize resource utilization or capacity thresholds, or identify an improperly configured firewall. Thus, it is imperative that the collected log data be secured and can only be accessed by authorized personnel.This does not apply to traffic logs generated on behalf of the device itself (management). Some devices store traffic logs separately from the system logs.

Check content

Verify the firewall's fine-grained permissions are configured to control access to the log store where the traffic log is located. If the firewall does not protect traffic log records from unauthorized read access while stored locally, this is a finding.

Fix text

Validate the firewall includes a baseline cryptographic module that provides confidentiality and integrity services for authentication and for protecting communications with adjacent systems. Configure role-based, fine-grained permissions management for controlling access.
