Nutanix AOS must enforce password complexity by requiring that at least one lowercase character be used.

Description
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 need to be tested before the password is compromised.

Check Text ( C-57694r846713_chk )
Confirm Nutanix AOS is configured to require complex passwords. Note: The value to require a number of lowercase characters to be set is expressed as a negative number in "/etc/security/pwquality.conf". Check the value for "lcredit" in "/etc/security/pwquality.conf" with the following command: $ sudo grep lcredit /etc/security/pwquality.conf lcredit = -1 If the value of "lcredit" is not set to a negative value, this is a finding.
