Title

All global initialization files must have mode 0644 or less permissive. (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.

Check Content

Check global initialization files permissions. # ls -l /etc/.login # ls -l /etc/profile # ls -l /etc/bashrc # ls -l /etc/environment # ls -l /etc/security/environ # ls -l /etc/csh.login # ls -l /etc/csh.cshrc If global initialization files exist and are more permissive than 0644, this is a finding.

Fix Text

Change the mode of the global initialization file(s) to 0644. # chmod 0644 <global initialization file>
