Description
Remote access is any access to an organizational operating system by a user (or an information system) communicating through an external, non-organization-controlled network. If cryptography is not used to protect these sessions, then the session data traversing the remote connection could be intercepted and potentially modified. Cryptography provides a means to secure the remote connection to prevent unauthorized access to the data traversing the remote access connection, thereby providing a degree of integrity. The encryption strength of mechanism is selected based on the security categorization of the information traversing the remote connection.

Check Text ( C-53757r2_chk )
The service "telnet" should be disabled, to check the status of the service, run the following command: sudo /usr/libexec/PlistBuddy -c "print com.apple.telnetd:Disabled" /var/db/launchd.db/com.apple.launchd/overrides.plist If the returned value isn't "true" or doesn't exist, this is a finding.

Fix Text (F-56219r1_fix)
To set the telnet service to disabled, run the following command: sudo defaults write /private/var/db/launchd.db/com.apple.launchd/overrides.plist "com.apple.telnetd" -dict Disabled -bool true
