Discussion

Using 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 in determining 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. Special characters are those characters that are not alphanumeric. Examples include: ~ ! @ # $ % ^ *.

Verify Nutanix AOS enforces password complexity by requiring that at least one special character be used.

Note: The value to require a number of special characters to be set is expressed as a negative number in "/etc/security/pwquality.conf".

Check the value for "ocredit" in "/etc/security/pwquality.conf" using the following command.

$ sudo grep ocredit /etc/security/pwquality.conf 
ocredit=-1

If the value of "ocredit" is not set to a negative value, this is a finding.
