1.274 RHEL-10-600500

Information

RHEL 10 must restrict the use of the "su" command.

GROUP ID: V-281205RULE ID: SV-281205r1166567

The "su" program allows commands to be run with a substitute user and group ID. It is commonly used to run commands as the root user. Limiting access to such commands is considered a good security practice.

Satisfies: SRG-OS-000373-GPOS-00156, SRG-OS-000312-GPOS-00123

Solution

Configure RHEL 10 to require users to be in the "wheel" group to run the "su" command.

Edit the configuration file:

$ sudo vi /etc/pam.d/su

Add the following lines:

auth required pam_wheel.so use_uid

$ sed '/^[[:space:]]*#[[:space:]]*auth[[:space:]]\+required[[:space:]]\+pam_wheel\.so[[:space:]]\+use_uid$/s/^[[:space:]]*#//' -i /etc/pam.d/su

If necessary, create a "wheel" group and add administrative users to the group.
