| Description |
|---|
| Without re-authentication, 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 re-authenticate. |
| ℹ️ Check |
|---|
| Verify that "/etc/sudoers" has no occurrences of "!authenticate" with the following command: $ grep '!authenticate' /etc/sudoers /etc/sudoers.d/* If any occurrences of "!authenticate" are returned, this is a finding. |
| ✔️ Fix |
|---|
| Configure AlmaLinux OS 9 to not allow users to execute privileged actions without authenticating. Remove any occurrence of "!authenticate" found in the "/etc/sudoers" file or files in the "/etc/sudoers.d" directory with the following command: $ sed -i '/\!authenticate/ s/^/# /g' /etc/sudoers /etc/sudoers.d/* |
