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.
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.
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
