What is NDR?

Network Detection and Response (NDR) is a cybersecurity solution that continuously monitors an organization's network to detect cyber threats and anomalous behavior using non-signature-based tools or techniques, responding to these threats through local capabilities or integrated with other cybersecurity tools/solutions.

How NDR Works?

High-performance NDR solutions leverage advanced machine learning and artificial intelligence to mimic cyber adversaries, techniques and procedures accompanied by the MITRE ATT&CK framework to precisely detect attacker behavior. It provides cybersecurity context by correlating network events across time, users and applications, and does so with high accuracy, greatly reducing investigative time and effort. It also feeds security detections and threat correlations into security information event management (SIEM) solutions for comprehensive security assessments.

Why Do We Need the NDR?

Traces of a cyber attack are usually found in three places: On the network, at the endpoint and in event logs.

• Endpoint Detection and Response (EDR) tools provide detailed visibility into the processes running on systems and the interactions between them. 
• NDR provides visibility into the interactions between all devices on the network. 
• Event logs, typically collected in SIEMs, cover all events that occur on computers and other information systems for which an event log is created. They are critical in resolving cyber security incidents.

Cybersecurity teams using these tools are empowered to answer a wide range of questions when responding to incidents or investigating threats. What did this entity or account do before the alert? What did it do after the alert? When did things start to go bad?

Advanced and sophisticated attackers use hidden encrypted HTTPS tunnels that blend in with normal traffic to initiate a command and control (C2) session, exfiltrate sensitive data through that session, and evade perimeter security controls. Such attacks are much harder to detect, but with the visibility provided by NDR solutions, detection is much easier. In addition, artificial intelligence and machine learning algorithms that use the metadata of network traffic collected by these platforms as input can provide much more accurate and faster cyber incident detection.

What is a Managed NDR (MNDR) Service?

With the 24x7 active monitoring and response service provided by ADEO, we continuously monitor your NDR platforms, helping to detect possible cyberattacks as quickly as possible with the data collected by NDR platforms operating at the network level. We maximize the efficiency you can get from NDR platforms with processes operated by expert analysts to respond quickly and accurately to detected attacks.
