Choose a randomized mix of upper and lower case letters, numbers and special characters.

You can protect your organization from password cracking attacks by following ways:

FreeBSD MD5-based which is also used on Linux and in Cisco IOS.

John the Ripper supports and detects the following Unix crypt(3) hash types: Also, JTR is available for several different platforms which enables you to use the same password cracking tool everywhere. JTR combines several cracking modes in one program and is fully configurable. John the Ripper is fast and replete with many key features. JTR will keep attempting to break the password continuously unless there is a termination command. The rate at which John the Ripper will guess the password is going to depends on the password’s strength and the offered wordlist. For this reason, dictionary attacks generally consume less time than brute force attacks.

In the dictionary attack, only words with the greatest possibility of success are tested. The difference with a brute force attack is that a very large number of key possibilities must be checked.
