Discussion

Use of a complex password helps to increase the time and resources required to compromise the password. Password complexity, or strength, is a measure of the effectiveness of a password in resisting attempts at guessing and brute-force attacks. Password complexity is one factor of several that determine how long it takes to crack a password. The more complex the password, the greater the number of possible combinations that need to be tested before the password is compromised.

Fix Text

Use the following commands to configure password complexity: aaa common-criteria policy PASSWORD_POLICY min-length 15 numeric-count 1 upper-case 1 lower-case 1

Check Content

Verify that the Cisco IOS XE router is configured to use complex passwords. The configuration should look similar to the example below: aaa common-criteria policy PASSWORD_POLICY min-length 15 numeric-count 1 upper-case 1 lower-case 1 If the use of complex passwords is not configured, this is a finding.
