The signature updates use to include the NSDB documentation files in an html directory. They are no longer present in the Sensor Signature updates. Do these files still exist for Sensor 3.0+? If so, where are they located on the Sensor?
The NSDB is no longer included on the sensors (since 2.5). The NSDB can be found on the management systems, currently CSPM and the Unix Director. Every signature update includes updates for the management systems which contain updates for the NSDB.
