Discussion

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

Check Content

Verify the module "pam_cracklib.so" is present. 

Procedure: 

# ls /lib/security/
 
Confirm that "pam_cracklib.so" is present in the directory listing. 

If "pam_cracklib.so"  is not present, this is a finding.

Verify the file "/etc/pam.d/common-password" is configured.

Procedure: 

# grep pam_cracklib /etc/pam.d/common-password*

If a line containing "password required pam_cracklib.so" is not present, this is a finding.

Fix Text

Configure SLES for vRealize to prevent the use of dictionary words for passwords.

Edit the file "/etc/pam.d/common-password". Configure "common-password" by adding a line such as: 

password  required pam_cracklib.so

Save the changes made to the file "/etc/pam.d/common-password".
