Laboratory exercises provide you the opportunity to explore standard UNIX commands and public domain software for maintaining security. Use of firewalls to insulate a network from the Internet is discussed, as well as threats arising because of the World Wide Web. Additional topics include SSH, Kerberos, and other strong authentication mechanisms.
