Description
Use of a complex password helps 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-234883r1009622_chk)

Verify the SUSE operating system enforces password complexity by requiring that at least one lowercase character. Check that the operating system enforces password complexity by requiring that at least one lowercase character be used by using the following command: > grep pam_cracklib.so /etc/pam.d/common-password password requisite pam_cracklib.so lcredit=-1 If the command does not return anything, the returned line is commented out, or has a second column value different from "requisite", or does not contain "lcredit=-1", this is a finding.

Fix Text (F-38034r618919_fix)

Configure the SUSE operating system to enforce password complexity by requiring at least one lowercase character. Edit "/etc/pam.d/common-password" and edit the line containing "pam_cracklib.so" to contain the option "lcredit=-1" after the third column.
