You can configure the Web Security appliance to have stricter access requirements for administrators 
logging into the appliance.

List of words to 
disallow in passphrases

Create a .txt file with each forbidden word on a separate line, then select the 
file to upload it. Subsequent uploads overwrite previous uploads. 

Passphrase Strength

You can display a passphrase-strength indicator when an administrative user 
enters a new passphrase.

This setting does not enforce creation of strong passphrases, it merely shows 
how easy it is to guess the entered passphrase. 

Select the roles for which you wish to display the indicator. Then, for each 
selected role, enter a number greater than zero. A larger number means that 
a passphrase that registers as strong is more difficult to achieve. This setting 
has no maximum value, but a very high number makes it effectively 
impossible to enter a passphrase that evaluates as "good." 

Experiment to see what number best meets your requirements. 

Passphrase strength is measured on a logarithmic scale. Evaluation is based 
on the U.S. National Institute of Standards and Technology rules of entropy 
as defined in NIST SP 800-63, Appendix A.

Generally, stronger passphrases:

Are longer

Include upper case, lower case, numeric, and special characters

Do not include words in any dictionary in any language.

To enforce passphrases with these characteristics, use the other settings on 
this page.
