Summary

In this chapter, we reviewed the basics of setting ownership and permissions for files and directories. We then covered what SUID and SGID can do for us when used properly, and the risk of setting them on our own executable files. Finally, we completed this roundup by looking at the two extended file attributes that deal with file security.

In the next chapter, we'll extend what we've learned here to more advanced file and directory access techniques. I'll see you there.
