Password complexity or strength is a measure of the effectiveness of a password in resisting attempts at guessing and brute-force attacks. Password length is one of several that helps to determine strength and how long it takes to crack a password.
The shorter the password, the lower the number of possible combinations that need to be tested before the password is compromised. Use of more characters in a password helps to exponentially increase the time and/or resources required to compromise the password.
Solution
Configure the Cisco router to enforce a minimum 15-character password length as shown in the example below.
R1(config)#aaa common-criteria policy PASSWORD_POLICY
R1(config-cc-policy)#min-length 15
R1(config-cc-policy)#exit
