Perception Update - Optimise DNS Classifier Performance

Enhance the performance of the DNS Policy Cache. Improvements have been made to allow many more lookups to be performed against the DNS blacklist.

Enables more fine grained control of the DNS blacklist by adding more lookup values without significantly increasing the amount of processing required.

Perception packs a huge capability into a small form factor, so we’re always looking for ways to do things either more efficiently or more effectively.  We’ve enhanced our DNS blacklist engine to increase the number of lookups while maintaining system performance.

As a result, the analyst can now rapidly identify more suspicious DNS lookups, focussing their attention on areas of concern.

This update is sensor based, and will be pushed to all managed customers at the pre-agreed upgrade time.  Self-monitored customers can update their own sensors using the software upgrade process.  If you have any further questions about this upgrade please contact us at info@perceptioncybersecurity.co
