About the Cisco Vulnerability Database Library

The Cisco Vulnerability Database (VDB) library provides links to the Cisco Firepower Application Detector Reference for each VDB release.

About the Cisco Vulnerability Database

The Cisco vulnerability database (VDB) is a database of known vulnerabilities to which hosts may be susceptible, as well as fingerprints for operating systems, clients, and applications. The system uses the VDB to help determine whether a particular host increases your risk of compromise.

The Cisco Talos Intelligence Group (Talos) issues periodic updates to the VDB. The time it takes to update the VDB and its associated mappings on the Firepower Management Center depends on the number of hosts in your network map. As a rule of thumb, divide the number of hosts by 1000 to determine the approximate number of minutes to perform the update.

You can find VDB updates on the VDB Software Downloads page on Cisco.com.
