Big Sur - Configure Sudoers to Authenticate Users on a Per -tty Basis

Information

The file /etc/sudoers _MUST_ be configured to include tty_tickets.

This rule ensures that the "sudo" command will prompt for the administrator's password at least once in each newly opened terminal window. This prevents a malicious user from taking advantage of an unlocked computer or an abandoned logon session by bypassing the normal password prompt requirement. Without the "tty_tickets" option, all open local and remote logon sessions would be authenticated to use sudo without a password for the duration of the configured password timeout window.

Solution

[source,bash]
----
/bin/cp /etc/sudoers /etc/sudoers.bk; /bin/echo "Defaults tty_tickets" >> /etc/sudoers
----
