Description
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 Text ( C-43629r670927_chk )
Check that the SLES for vRealize enforces password complexity by requiring that at least one numeric character be used by running the following command: # grep dcredit /etc/pam.d/common-password-vmware.local If "dcredit" is not set to "-1" or is not set 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 (F-43588r670928_fix)
If "dcredit" was not set at all in /etc/pam.d/common-password-vmware.local, run the following command: # sed -i '/pam_cracklib.so/ s/$/ dcredit=-1/' /etc/pam.d/common-password-vmware.local If "dcredit" was set incorrectly, run the following command: # sed -i '/pam_cracklib.so/ s/dcredit=../dcredit=-1/' /etc/pam.d/common-password-vmware.local
