Elevate The SELinux Context When An Administrator Calls The Sudo Command

Description

Configure the operating system to elevate the SELinux context when an administrator calls the sudo command. Edit a file in the /etc/sudoers.d directory with the following command:

sudo visudo -f /etc/sudoers.d/CUSTOM_FILE

Use the following example to build the CUSTOM_FILE in the /etc/sudoers.d directory to allow any administrator belonging to a designated sudoers admin group to elevate their SELinux context with the use of the sudo command:

%wheel ALL=(ALL) TYPE=sysadm_t ROLE=sysadm_r ALL

Rationale

Preventing non-privileged users from executing privileged functions mitigates the risk that unauthorized individuals or processes may gain unnecessary access to information or privileges.

Privileged functions include, for example, establishing accounts, performing system integrity checks, or administering cryptographic key management activities. Non-privileged users are individuals who do not possess appropriate authorizations. Circumventing intrusion detection and prevention mechanisms or malicious code protection mechanisms are examples of privileged functions that require protection from non-privileged users.
