Computer systems typically store the passwords which allow access to the system in a password file which is cryptographically protected from prying eyes. A number of password cracking programs are available for extracting the passwords from a password file. Some examples are the ''Crack'', ''John the Ripper'' and ''L0phtCrack'' programs, each of which attempts to decrypt password files. Obviously, the best approach to avoiding such programs being run is to prevent the password file from falling into the wrong hands and carefully monitoring systems to ensure unauthorized programs are not running.
