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.

Who does this work

17 NICE work roles and 9 EC-Council certifications.

This is an inference across published mappings, not a single claim by anyone. This check maps to a control, which maps to a Cybersecurity Framework outcome, which NIST assigns to the work roles below. EC-Council separately maps its certifications to those same roles.

A certification prepares someone for a role. It is not evidence that a holder is qualified, and neither NIST nor EC-Council has stated that any certification here addresses this check.

Work-role assignments published by NIST (NICE Framework Components 2.2.0 and the CSF 2.0 OLIR crosswalk). Certification mappings published by EC-Council.

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.
