Vulnerability discussion

Password complexity, or strength, is a measure of the effectiveness of a password in resisting guessing and brute-force attacks. Password complexity is one factor of several that determine how long it takes to crack a password. The more complex the password is, the greater the number of possible combinations that need to be tested before the password is compromised. Use of a complex password helps to increase the time and resources required to compromise the password. The PSWD GSO record values specify the rules that ACF2 will apply when a user selects a new password. Improper setting of any of these fields, individually or in combination with another, can result in weakened passwords and compromise the security of the processing environment.

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.
