Customers of Cisco ASA who purchase a VulnCheck IP Intelligence license are able to leverage Cisco's Dynamic Block List (DBL) functionality to block attacker Command & Control (C2) infrastructure detected by VulnCheck.
Cisco ASA provides an easy to use custom list functionality for Cisco ASA FirePOWER, which may be used with third-party intelligence providers like VulnCheck.
For more information on these features from Cisco see: Configure IP Blacklisting while Using Cisco Security Intelligence through ASDM
You can use any third-party IP database for the custom list for which Firepower module contacts the third party server to fetch the IP address list. In order to configure this, navigate to Configuration > ASA FirePOWER Configuration > Object Management > SecurityIntelligence > Network Lists and Feeds
Then in the Feed URL
input box, simply add:
