Vulnerability discussion

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

Check content

Verify that SLES for vRealize enforces a minimum 15-character password length, by running the following command: # grep pam_cracklib /etc/pam.d/common-password-vmware.local # grep pam_cracklib /etc/pam.d/common-password If the result does not contain "minlen=15" or higher, this is a finding.

Fix text

If "minlen" 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/$/ minlen=15/' /etc/pam.d/common-password-vmware.local If "minlen" was set incorrectly, run the following command to set it to "15": # sed -i '/pam_cracklib.so/ s/minlen=../minlen=15/' /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.
