| Description |
|---|
| Without reauthentication, users may access resources or perform tasks for which they do not have authorization. When SLEM 5 provides the capability to change user authenticators, change security roles, or escalate a functional capability, it is critical the user reauthenticate. |
| ℹ️ Check |
|---|
| Verify that SLEM 5 requires reauthentication when changing authenticators, roles, or escalating privileges with the following command: > sudo egrep -i '(nopasswd|!authenticate)' /etc/sudoers If any uncommented lines containing "!authenticate", or "NOPASSWD" are returned and active accounts on the system have valid passwords, this is a finding. |
| ✔️ Fix |
|---|
| Configure SLEM 5 to remove any occurrence of "NOPASSWD" or "!authenticate" found in the "/etc/sudoers" file. If the system does not use passwords for authentication, the "NOPASSWD" tag may exist in the file. |
