Discussion

If SLES for vRealize system 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

Check "/etc/pam.d/common-password" for "pam_cracklib" configuration:

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

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

Ensure the passwd command uses the common-password settings.

# grep common-password /etc/pam.d/passwd

If a line "password include common-password" is not found then the password checks in common-password will not be applied to new passwords, this is a finding.

Fix Text

Edit "/etc/pam.d/common-password" and configure "pam_cracklib" by adding a line such as "password requisite pam_cracklib.so".
