MACOSX 10.6: GEN001540 M6 (in version v1 r3)

Title

All files and directories contained in interactive user home directories must be owned by the home directory's owner. (Cat III impact)

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.

Check Content

NOTE: For each user, check for the presence of files and directories within the user's home directory not owned by the home directory owner. Open a terminal session and enter the following command. find /<usershomedirectory> -not -user <username> -exec ls -ld {} \; If the user's home directories contain files or directories not owned by the home directory owner, this is a finding.

Fix Text

Open a terminal session and enter the following command to change the ownership of files and directories in user home directories to the owner of the home directory. chown <account-owner> <filename>
