The macOS system must disable Unix-to-Unix Copy Protocol (UUCP) service.

| Description | ||||
| The system must not have the UUCP service active. UUCP, a set of programs that enables sending files between different Unix systems and sending commands to be executed on another system, is not essential and must be disabled to prevent unauthorized connection of devices, transfer of information, and tunneling. Note: UUCP service is disabled at startup by default with macOS. | ||||

Check Text (C-277089r1149391_chk)
Verify the macOS system is configured to disable UUCP service with the following command:
result="FAIL"
enabled=$(/bin/launchctl print-disabled system | /usr/bin/grep '"com.apple.uucp" => enabled')
running=$(/bin/launchctl print system/com.apple.uucp 2>/dev/null)
if [[ -z "$running" ]] && [[ -z "$enabled" ]]; then
result="PASS"
elif [[ -n "$running" ]]; then
result=result+" RUNNING"
elif [[ -n "$enabled" ]]; then
result=result+" ENABLED"
fi
echo $result
If the result is not "PASS", this is a finding.
Fix Text (F-81149r1149325_fix)
Configure the macOS system to disable UUCP service with the following command:
/bin/launchctl bootout system/com.apple.uucp
/bin/launchctl disable system/com.apple.uucp
The system may need a restart for the update to take effect.
