Discussion

Use of a complex password helps to increase the time and resources required to compromise the password. Password complexity, or strength, is a measure of the effectiveness of a password in resisting attempts at guessing and brute-force attacks. Password complexity is one factor of several that determines how long it takes to crack a password. The more complex the password, the greater the number of possible combinations that need to be tested before the password is compromised.

Check Content

Check SLES for vRealize enforces password complexity by requiring that at least one upper-case character be used by using the following command:

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

If "ucredit" is not set to "-1" or not at all, this is a finding.

Expected Result:
password requisite pam_cracklib.so dcredit=-1 ucredit=-1 lcredit=-1 ocredit=-1 minlen=14 difok=4 retry=3

Fix Text

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

# sed -i '/pam_cracklib.so/ s/$/ ucredit=-1/' /etc/pam.d/common-password-vmware.local

If "ucredit" was set incorrectly, run the following command to set it to "-1":

# sed -i '/pam_cracklib.so/ s/ucredit=../ucredit=-1/' /etc/pam.d/common-password-vmware.local
