SLEM-05-611015 - SLEM 5 must enforce passwords that contain at least one lowercase character.

Information

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.

Solution

Configure SLEM 5 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.
