macOS 26 - Tahoe

The macOS system must configure audit retention to seven days

STIG ID: APPL-26-001029 | SRG: SRG-OS-000341-GPOS-00132 | Severity: Low | CCI: CCI-001849 | Vulnerability ID: V-277074

Description

The audit service must be configured to require that records be kept for an organizational-defined value before deletion unless the system uses a central audit record storage facility.

When "expire-after" is set to "7d", the audit service will not delete audit logs until the log data criteria is met.

Check

C-81229r1148672_chk

Verify the macOS system is configured to set audit retention to seven days with the following command:

/usr/bin/awk -F: '/expire-after/{print $2}' /etc/security/audit_control

If the result is not "7d", this is a finding.

Fix

F-81134r1148673_fix

Configure the macOS system to set audit retention to seven days with the following command:

/usr/bin/sed -i.bak 's/^expire-after.*/expire-after:7d/' /etc/security/audit_control; /usr/sbin/audit -s
