Vulnerability discussion

Device management includes the ability to control the number of administrators and management sessions that manage a device. Limiting the number of allowed administrators and sessions per administrator based on account type, role, or access type is helpful in limiting risks related to DoS attacks.This requirement addresses concurrent sessions for administrative accounts and does not address concurrent sessions by a single administrator via multiple administrative accounts. The maximum number of concurrent sessions should be defined based upon mission needs and the operational environment for each system. At a minimum, limits must be set for SSH, HTTPS, account of last resort, and root account sessions.

Check content

Review the network device configuration to see if the device limits the number of concurrent sessions to an organization-defined number for all administrator accounts and/or administrator account types. If the network device does not limit the number of concurrent sessions to an organization-defined number for each administrator account and/or administrator account type, this is a finding.

Fix text

Configure the network device to limit the number of concurrent sessions to an organization-defined number for all administrator accounts and/or administrator account types.

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.
