Sarthak Grover Presents on Home Network Security at Ubicomp Workshop

Leave a comment

Sarthak Grover presented a new system built on BISmark for detecting malware in home networks at Ubicomp.  The current system, called Panoptes, tracks DNS lookups from hosts inside a home and compares the DNS lookups against a blacklist on the router.   The system then notifies the user if the DNS lookups suggest the presence of malware on a device in the home.

The system significantly enhances the capabilities of existing systems for providing security in home networks, building on deployed products such as Comcast’s Constant Guard service.  He and Yogesh Mundada are currently working with Comcast on designing an SDN-based system that builds on this design, called SAZO, as part of a larger field deployment.  More to come on SAZO in the future!
