Title

All global initialization files must be owned by root. (Cat II impact)

Discussion

Global initialization files are used to configure the user's shell environment upon login. Malicious modification of these files could compromise accounts upon logon. Failure to give ownership of sensitive files or utilities to root or bin provides the designated owner and unauthorized users with the potential to access sensitive information or change the system configuration which could weaken the system's security posture.

Check Content

Check the ownership of global initialization files. Procedure: # ls -lL /etc/.login /etc/profile /etc/bashrc /etc/environment /etc/security/environ /etc/csh.login /etc/csh.cshrc If any global initialization file exists and is not owned by root, this is a finding.

Fix Text

Change the ownership of global initialization files with incorrect ownership. Procedure: # chown bin <global initialization files>
