Vulnerability 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 in determining 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.Special characters are those characters that are not alphanumeric. Examples include: ~ ! @ # $ % ^ *.

Check content

Verify SLES for vRealize enforces password complexity by requiring that at least one special character be used by using the following command: Check the password "ocredit" option: # grep pam_cracklib.so /etc/pam.d/common-password Confirm the "ocredit" option is set to "-1" as in the example: password requisite pam_cracklib.so ocredit=-1 There may be other options on the line. If no such line is found, or the "ocredit" is not "-1", this is a finding.

Fix text

Configure SLES for vRealize to enforce password complexity by requiring that at least one special character be used by running the following command: If "ocredit" 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/$/ ocredit=-1/' /etc/pam.d/common-password-vmware.local If "ocredit" was set incorrectly, run the following command: # sed -i '/pam_cracklib.so/ s/ocredit=../ocredit=-1/' /etc/pam.d/common-password-vmware.local

Pro Tips

Lavender hyperlinks in small type off to the right (of CSS class id, if you view the page source) point to globally unique URIs for each document and item. Copy the link location and paste anywhere you need to talk unambiguously about these things.

You can obtain data about documents and items in other formats. Simply provide an HTTP header Accept: text/turtle or Accept: application/rdf+xml.
