Description
Local initialization files are used to configure the user's shell environment upon logon. Malicious modification of these files could compromise accounts upon logon.

ℹ️ Check
Verify that all local initialization files have a mode of "0740" or less permissive with the following command: Note: The example will be for the "bingwa" user, who has a home directory of "/home/bingwa". $ find /home/bingwa/.[^.]* -maxdepth 0 -perm -740 -exec stat -c "%a %n" {} \; \| more 755 /home/bingwa/.somepermissivefile If any local initialization files are returned, this indicates a mode more permissive than "0740", and this is a finding.
