Kennebunk, ME — July 22, 2015 -Plixer International, a leading network incident response and flow forensics company, announced today that Cofounder Michael Patterson will be presenting an upcoming webcast.
The webcast “DNS Monitoring for Botnets” is scheduled for Thursday, August 6th, 2015 at 1PM EDT. Topics covered will include:
- How DNS works
- NXDOMAIN and DNS TXT message abuse

“Because basic DNS communications are critical to most Internet connections, it can’t be blocked,” says Michael Patterson, CEO of Plixer International, Inc. “Both security companies and malware developers are abusing the protocol the same way. Security teams need to be aware of the abuse and how to minimize their risk.”
The presentation provides a technical overview on how DNS works, including details on the 13 root DNS servers, how they are contacted with anycasting, recursive and iterative DNS operations, and authoritative DNS responsibilities. Fully Qualified Domain Names (FQDN), top level, second level, third level domain, and other terms are also introduced and explained in order to convey how DNS communications can be used for maliciously intended activities.
