The HYCU virtual appliance must enforce a minimum 15-character password length.

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.

Check for the value of the "minlen" option in "/etc/security/pwquality.conf" with the following command: grep minlen /etc/security/pwquality.conf

If the minlen value is not set to "15", this is a finding.

Check for the value of the "user.password.min.length" variable in "/opt/grizzly/config.properties" HYCU configuration file with the following command: grep user.password.min.length /opt/grizzly/config.properties

If the value is not set to 15 or more, this is a finding.

Add the following line to "/etc/security/pwquality.conf" (or modify the line to have the required value). minlen = 15

Add or modify the following line in the /opt/grizzly/config.properties configuration file: user.password.min.length=15

Reload the HYCU application by running the following command: sudo systemctl reload grizzly
