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.
