macOS 26 - Tahoe
The macOS system must configure sudo to log events
STIG ID: APPL-26-000190 | SRG: SRG-OS-000064-GPOS-00033 | Severity: Medium | CCI: CCI-000172 | Vulnerability ID: V-277059
Description
Sudo must be configured to log privilege escalation.
Without logging privilege escalation, it is difficult to identify attempted attacks because no audit trail is available for forensic investigation.
Check
C-81214r1148627_chk
Verify the macOS system is configured to log privilege escalation with the following command:
/usr/bin/sudo /usr/bin/sudo -V | /usr/bin/grep -c "Log when a command is allowed by sudoers"
If the result is not "1", this is a finding.
Fix
F-81119r1148628_fix
Configure the macOS system to log privilege escalation with the following command:
/usr/bin/find /etc/sudoers* -type f -exec sed -i '' '/^Defaults[[:blank:]]*\!log_allowed/s/^/# /' '{}' \;
/bin/echo "Defaults log_allowed" >> /etc/sudoers.d/mscp
