os_uucp_disable Disable Unix-to-Unix Copy Protocol Service

NIST macOS Security Compliance Project Sequoia Guidance, Revision 4.0 (be5491f)

first version loaded macOS

Title

Disable Unix-to-Unix Copy Protocol Service

Control

/bin/launchctl print-disabled system | /usr/bin/grep -c '"com.apple.uucp" => disabled'

Discussion

The system _MUST_ not have the Unix-to-Unix Copy Protocol (UUCP) service active.

UUCP, a set of programs that enable the sending of files between different UNIX systems as well as sending commands to be executed on another system, is not essential and _MUST_ be disabled in order to prevent the unauthorized connection of devices, transfer of information, and tunneling.

NOTE: UUCP service is disabled at startup by default macOS.

----
The system may need to be restarted for the update to take effect.
