File Security

  • Ensure that file and directory permissions are the minimum needed to allow users to do their jobs.

  • Use groups and group permissions, where possible, to control access to files.

  • Use ACLs where appropriate, but make sure you keep track of the files that use them.

  • Regularly search for setuid and setgid programs and investigate any that look suspicious.

  • Setting the sticky bit on all publicly writeable directories used for temporary files will prevent users from deleting other people's files.
