Title

The macOS system must configure audit_control owner to mode 440 or less permissive.

Control

Verify the macOS system is configured with the audit_control to mode 440 or less with the following command: /bin/ls -l /etc/security/audit_control | /usr/bin/awk '!/-r--[r-]-----|current|total/{print $1}' | /usr/bin/wc -l | /usr/bin/xargs If the result is not "0", this is a finding.

Discussion

/etc/security/audit_control must be configured so that it is readable only by the root user and group wheel. The audit service must be configured with the correct mode to prevent normal users from manipulating audit log configurations.
