| 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-217118r1015207_chk)
Verify the SUSE operating system enforces password complexity by requiring that at least one lower-case character.
Check that the operating system enforces password complexity by requiring that at least one lower-case 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-18344r369511_fix)
Configure the SUSE operating system to enforce password complexity by requiring at least one lower-case 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.
