Review the currently mounted local filesystems using the following to find all world writable files on local JFS/JFS2 filesystems only: Note: the list generated by the command below is for all groups, not just the default system groups. the command without the argument -ls will create a list than can be fed to /usr/bin/xargs to blindly remove the group write permissions. find -L / \( -fstype jfs -o -fstype jfs2 \) -type f -perm -g+w -ls Remedy any files in the list, e.g., chmod g-w {filename} Document any files, and motivate why they are group writeable, and also add documentation re: when/why this exception ceases.
