Title
The SUSE operating system must prevent the use of dictionary words for passwords. (Cat II impact)
Discussion
If the SUSE operating system 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 the SUSE operating system prevents the use of dictionary words for passwords. Check that the SUSE operating system 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 command does not return anything, or the returned line is commented out, this is a finding.
Fix Text
Configure the SUSE operating system 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
