Vulnerability discussion

Password complexity, or strength, is a measure of the effectiveness of a password in resisting attempts at guessing and brute-force attacks. To meet password policy requirements, passwords need to be changed at specific policy-based intervals.If the network device 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.

Check content

Go to Device >> Setup >> Management View the "Minimum Password Complexity" window. If the "Prevent Password Reuse Limit" field is not "5", this is a finding.

Fix text

Go to Device >> Setup >> Management In the "Minimum Password Complexity" window, select the "Edit" icon (the gear symbol in the upper-right corner of the pane). In the "Prevent Password Reuse Limit" field, enter "5". Check the "Enabled" box, then select "OK". Commit changes by selecting "Commit" in the upper-right corner of the screen. Select "OK" when the confirmation dialog appears.

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.
