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.
Verify the SUSE operating system prohibits the reuse of a password for a minimum of five (5) generations. Check that the SUSE operating system prohibits the reuse of a password for a minimum of five (5) generations with the following command: # grep pam_pwhistory.so /etc/pam.d/common-password password requisite pam_pwhistory.so remember=5 useauthtok If the command does not return anything, the returned line is commented out, or has a second column value different from "requisite", or does not contain "remember" value, or the value is less than "5", or is missing the "useauthtok" keyword, this is a finding.
Configure the SUSE operating system password history to prohibit the reuse of a password for a minimum of five generations. Edit "/etc/pam.d/common-password" and edit the line containing "pam_pwhistory.so" to contain the option "remember=5 useauthtok" after the third column.
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.
