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. |

Verify the Ubuntu operating system enforces password complexity by requiring that at least one lower-case character be used. Determine if the field "lcredit" is set in the "/etc/security/pwquality.conf" file with the following command: $ grep -i "lcredit" /etc/security/pwquality.conf lcredit=-1 If the "lcredit" parameter is greater than "-1" or is commented out, this is a finding. |
