| 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 that the user reauthenticate.

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