| Description |
|---|
| Without reauthentication, users may access resources or perform tasks for which they do not have authorization. When operating systems provide the capability to escalate a functional capability, it is critical the user reauthenticate. |
| ℹ️ Check |
|---|
| Verify the "/etc/sudoers" file has no occurrences of "NOPASSWD" or "!authenticate" with the following command: $ sudo egrep -i '(nopasswd|!authenticate)' /etc/sudoers /etc/sudoers.d/* If any occurrences of "NOPASSWD" or "!authenticate" return from the command, this is a finding. |
| ✔️ Fix |
|---|
| Remove any occurrence of "NOPASSWD" or "!authenticate" found in "/etc/sudoers" file or files in the "/etc/sudoers.d" directory. |
