What is Network Detection & Response? NDR evolved out of Network Security Today’s  network detection and response (NDR)  has a long history, evolving out of network security and  network traffic analysis (NTA) .  The historical definition of  network security  is to use a perimeter firewall and Intrusion Prevention Systems to screen traffic coming into the network, but as  IT and security technology  have evolved, the definition is much broader now due to modern attacks leveraging more complex approaches. Today,  network security  is everything a company does to ensure the security of its networks, and everything connected to them. This includes the network, the cloud (or clouds), endpoints, servers, IoT, users and applications**.**  Network security  products seek to use physical and virtual preventive measures to protect the network and its assets from unauthorized access, modification, destruction and misuse.

  Every  security tool  vendor talks about  detection and response , so what makes  NDR  so special, and how does it relate to  XDR /   Open XDR ? NDR  is special because it focuses on the nerve center of an organization’s IT infrastructure: the network. Wireless or wired device, endpoint or server, application, user or cloud – all are connected to the network, and the  network  never lies. It’s the foundation of truth about what’s happening in the IT infrastructure.  NDR  solutions use non-signature-based techniques (for example,  machine learning  or other analytical techniques) for unknown attacks alongside quality signature-based techniques (for example  threat intelligence  fused in-line for alerts) for known attacks to detect suspicious traffic or activities.  NDR  can ingest data from dedicated sensors, existing firewalls,  IPS/IDS , metadata like NetFlow, or any other network data...
