What Is Network Detection And Response (NDR)? Ultimate Guide
Datamation, February 28th, 2023
Network detection and response, or NDR, is a cybersecurity tool that continuously scans traffic for potential risks by using machine learning and artificial intelligence (AI). When risks are encountered, NDR systems initiate an immediate counterattack and begin to repair any damage.
Enterprise networks that rely solely on legacy network security tools like firewalls are much more vulnerable to attack or infiltration than they would be with a solution that includes NDR. The key benefit is the continuous nature of NDR oversight.
While a firewall (perhaps the most commonly used network security tool) can stop unwanted traffic, filtering is limited to parameters established manually by a security team member. Often, firewalls can only examine specific elements like IP addresses, protocols, and port numbers. NDR, on the other hand, evaluates traffic within a larger context and makes adjustments as it 'learns' about network behavior patterns.
