The firewall implementation must protect audit log information from unauthorized read access.

Description
Auditing of account use and user actions is a critical part of the security architecture. Auditable events must be logged. If the firewall becomes unable to write events to the audit log, this is known as an audit processing failure. Audit processing failures include software and hardware errors, failures in the audit capturing mechanisms, and audit storage capacity being reached or exceeded. Audit log data must be protected from unauthorized access, including from legitimate administrators who do not have a need for this type of access. Without this protection, a compromise or loss of log data needed for incident analysis or risk assessment could result.

Check Text ( C-SRG-NET-000098-FW-000064_chk )
Verify a security policy for the audit logs is in place which allows only system administrators with the proper authorization to read the audit log on the firewall. If audit logs are not protected from unauthorized read access, this is a finding.

Fix Text (F-SRG-NET-000098-FW-000064_fix)
Create and implement an access control security policy to prevent unauthorized read access of the audit logs on the firewall.
