runZero Hour, Ep. 15: Network topology, detailed fingerprinting and MODBUS love

On this episode of runZero Hour, Rob King and Tom Sellers welcome Brianna Cluck, researcher extraordinaire from GreyNoise Intelligence, covering a range of topics including:

  • Network topology: We go under the hood on network topology mapping and see how to spot exposures and segmentation issues. Plus, we learn about Brianna’s new research on tags with suspicious intention!
  • Fingerprinting network devices in detail: We deconstruct our updated Palo Alto probes and show you how to uncover more attributes on your network devices using creative new techniques.
  • MODBUS love: It’s the ICS protocol so popular it’s got a ton of proprietary, vendor-based extensions! Brianna shares recent research and tips for staying on top of the variations to keep your OT secure.
  • runZero updates: We've got new queries and categorizations for you, plus the ability to age out attributes to improve fingerprinting accuracy and reprocess tasks to fine tune asset data without losing history.
