| Check Text (C-62587r933600_chk) |
| At the command line, run the following commands to verify users with a set password are not allowed to sudo without reauthentication: # grep -ihs nopasswd /etc/sudoers /etc/sudoers.d/*|grep -vE '(^#|^%)' # awk -F: '($2 != "x" && $2 != "!") {print $1}' /etc/shadow If any account listed in the first output is also listed in the second output and is not documented, this is a finding. |
