Discussion

Password complexity, or strength, is a measure of the effectiveness of a password in resisting attempts at guessing and brute-force attacks. If the information system or application allows the user to consecutively reuse their password when that password has exceeded its defined lifetime, the end result is a password that is not changed as per policy requirements.

Check Content

Verify that the SLES for vRealize prohibits the reuse of a password for a minimum of five generations by running the following commands:

# grep pam_pwhistory.so /etc/pam.d/common-password-vmware.local 

If the "remember" option in /etc/pam.d/common-password-vmware.local is not "5" or greater, this is a finding.

Fix Text

Configure pam to use password history. 

If "remember" was not set at all in /etc/pam.d/common-password-vmware.local, run the following command:

# sed -i '/pam_cracklib.so/ s/$/ remember=5/' /etc/pam.d/common-password-vmware.local

If "remember" was set incorrectly, run the following command to set it to "5":

# sed -i '/pam_cracklib.so/ s/remember=./remember=5/' /etc/pam.d/common-password-vmware.local
