The Cisco Network Security Database (NSDB) can be accessed, or invoked, through the user interface of Security Manager.
The NSDB is a database of security information that explains the signatures the IPS uses along with the vulnerabilities on which these signatures are based. The NSDB contains a description for each attack signature that the sensor can detect.
In Security Manager, the table in the content area of the IPS Signature policy contains several columns by default, one of which is Signature ID. The Signature ID column contains hyperlinks to the NSDB. Clicking on the link in the ID column will trigger the opening of an external browser window that opens to the entry in MySDN for that signature.
