If multifactor authentication is not available and passwords must be used, the Palo Alto Networks security platform must enforce password complexity by requiring that at least one lowercase character be used.

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 determines how long it takes to crack a password. The more complex the password, the greater the number of possible combinations that needs to be tested before the password is compromised.

Go to Device >> Setup >> Management. View the "Minimum Password Complexity" window. If the "Minimum Lowercase Letters" field is not "1", this is a finding.

Go to Device >> Setup >> Management. In the "Minimum Password Complexity" window, select the "Edit" icon (the gear symbol in the upper-right corner of the pane). In the "Minimum Lowercase Letters" field, enter "1". Check the "Enabled" box, then select "OK". Commit changes by selecting "Commit" in the upper-right corner of the screen. Select "OK" when the confirmation dialog appears.
