| 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-18345r369507_chk) |
| Verify the SUSE operating system enforces password complexity by requiring that at least one upper-case character. Check that the operating system enforces password complexity by requiring that at least one upper-case character be used by using the following command: # grep pam_cracklib.so /etc/pam.d/common-password password requisite pam_cracklib.so ucredit=-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 "ucredit=-1", this is a finding. |
| Fix Text (F-18343r369508_fix) |
| Configure the SUSE operating system to enforce password complexity by requiring at least one upper-case character. Edit "/etc/pam.d/common-password" and edit the line containing "pam_cracklib.so" to contain the option "ucredit=-1" after the third column. |
