| 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-261379r996570_chk)
Verify SLEM 5 enforces password complexity by requiring at least one numeric character with the following command:
> grep pam_cracklib.so /etc/pam.d/common-password
password requisite pam_cracklib.so dcredit=-1
If the value for "dcredit" is not "-1", if "dcredit" is missing from the line, the second column value different from "requisite", the line is commented out, or the line is missing, this is a finding.
Fix Text (F-65016r996003_fix)
Configure SLEM 5 to enforce password complexity by requiring at least one numeric character.
Edit "/etc/pam.d/common-password" and edit the line containing "pam_cracklib.so" to contain the option "dcredit=-1" after the third column.
