1.18 CISC-ND-000550

Information

The Cisco switch must be configured to enforce a minimum 15-character password length.

GROUP ID: V-220589
RULE ID: SV-220589r1015280

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 factor 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 switch to enforce a minimum 15-character password length as shown in the example below:

SW1(config)#aaa common-criteria policy PASSWORD_POLICY
SW1(config-cc-policy)#min-length 15
SW1(config-cc-policy)#exit
