Discussion

If users do not own the files in their directories, unauthorized users may be able to access them. Additionally, if files are not owned by the user, this could be an indication of system compromise.

For each user in the /etc/passwd file, check for the presence of files and directories within the user's home directory not owned by the home directory owner.

Procedure:
# find /<usershomedirectory> ! -fstype nfs ! -user <username> ! \( -name .bashrc -o -name .bash_login -o -name .bash_logout -o -name .bash_profile -o -name .cshrc -o -name .kshrc -o -name .login -o -name .logout -o -name .profile -o -name .tcshrc -o -name .env -o -name .dtprofile -o -name .dispatch -o -name .emacs -o -name .exrc \) -exec ls -ld {} \;

If user home directories contain files or directories not owned by the home directory owner, this is a finding.
