Title
SLEM 5 must use a Linux Security Module configured to enforce limits on system services. (Cat I impact)
Discussion
Without verification of the security functions, security functions may not operate correctly and the failure may go unnoticed. Security function is defined as the hardware, software, and/or firmware of the information system responsible for enforcing the system security policy and supporting the isolation of code and data on which the protection is based. Security functionality includes, but is not limited to, establishing system accounts, configuring access authorizations (i.e., permissions, privileges), setting events to be audited, and setting intrusion detection parameters. This requirement applies to operating systems performing security function verification/testing and/or systems and environments that require this functionality.
Check Content
Verify "SELinux" is active and in "Enforcing" mode with the following command: > sudo getenforce Enforcing If "SELinux" is not in "Enforcing" mode, this is a finding.
Fix Text
Configure SLEM 5 to verify correct operation of all security functions. Add or modify the following line in the "/etc/selinux/config" file: SELINUX=enforcing A reboot is required for the changes to take effect.
