Implementing the sticky bit on the directory can stop people from accidentally deleting files that they don’t own. How can this technique be used to implement the concept of least privilege, and how can it be used to assure file availability?
[Least privilege refers to having the minimal access to one’s job. The sticky bit technique could be considered a form of least privilege as only people with the correct access, file owner/directory owner/super user, will be able to rename or delete these files. Users not in these categories will not be able to alter these files.]
