In this episode of Nomios 101, Will Reincke interviews Fraser Kyne from Arista Networks about the critical role of Network Detection and Response (NDR) in modern cybersecurity. Fraser emphasises that as networks become more complex with cloud integration and remote work, NDR provides essential visibility and threat detection capabilities. He clarifies the differences between NDR, XDR, and EDR, and advocates for a layered security approach. Fraser likens NDR to CCTV surveillance in a nightclub, complementing the 'bouncer' role of EDR. He discusses how NDR uses machine learning to analyse network data and stresses the importance of the "SOC triad" for comprehensive security. The episode wraps up with an invitation for listeners to see Arista's NDR in action through a demonstration or evaluation.
