Discussion

If SLEM 5 allows the user to select passwords based on dictionary words, this increases the chances of password compromise by increasing the opportunity for successful guesses and brute-force attacks.

Check Content

Verify SLEM 5 prevents the use of dictionary words for passwords with the following command:

     > grep pam_cracklib.so /etc/pam.d/common-password
     password requisite pam_cracklib.so

If the second column value is different from "requisite", the line is commented out, or the line is missing, this is a finding.

Fix Text

Configure SLEM 5 to prevent the use of dictionary words for passwords.

Edit "/etc/pam.d/common-password" and add the following line:

password requisite pam_cracklib.so
