Vulnerability discussion

If the keys used for routing protocol authentication are guessed, the malicious user could create havoc within the network by advertising incorrect routes and redirecting traffic. Some routing protocols allow the use of key chains for authentication. A key chain is a set of keys that is used in succession, with each having a lifetime of no more than 180 days. Changing the keys frequently reduces the risk of them eventually being guessed.Keys cannot be used during time periods for which they are not activated. If a time period occurs during which no key is activated, neighbor authentication cannot occur, and therefore routing updates will fail. Therefore, ensure that for a given key chain, key activation times overlap to avoid any period of time during which no key is activated.

This requirement is not applicable for the DoDIN Backbone. Review the start times for each key within the configured key chains used for routing protocol authentication as shown in the example below. security { … … … authentication-key-chains { key-chain BGP_KEY { key 1 { secret "$9$PTQnhclvMX3687"; ## SECRET-DATA start-time "2018-5-1.12:00:00 +0000"; } key 2 { secret "$9$iq.5OBESyKfTlM"; ## SECRET-DATA start-time "2018-9-1.12:00:00 +0000"; } key 3 { secret "$9$ZADjqAtOIRSk.hr"; ## SECRET-DATA start-time "2019-1-1.12:00:00 +0000"; } } } } Note: Currently Junos does not support key chains for OSPF and RIP If any key has a lifetime of more than 180 days, this is a finding.

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.
