Vulnerability discussion

By limiting the number of failed login attempts, the risk of unauthorized system access via user password guessing, otherwise known as brute-forcing, is reduced.

Check content

Determine if the network device is either configured to enforce the limit of three consecutive invalid logon attempts by a user during a 15-minute time period or configured to use an authentication server which would perform this function. If the limit of three consecutive invalid logon attempts by a user during a 15-minute time period is not enforced, this is a finding.

Fix text

Configure the network device or its associated authentication server to enforce the limit of three consecutive invalid logon attempts by a user during a 15-minute time period.

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.
