What is Network Detection and Response (NDR)?

Gaining complete visibility into increasingly complex networks is critical to detecting and preventing threats to your organisation before they cause a breach. With this need for network visibility becoming a crucial issue, Network Detection and Response (NDR) is a great option for teams trying to prevent threat actors from lingering undetected in their networks leading to an eventual breach.

Definition of Network Detection and Response

Used by organisations to detect and prevent malicious activity in an organisation, Network Detection and Response describes a category of security solutions that are used to investigate and mitigate the risk of attackers. It is a progressive security solution providing a centralised machine-based analysis of network traffic and response solutions.

NDR solutions provide a single solution for visibility across on-prem, remote, and cloud environments. These non-malware threats include, but are certainly not limited to:

Insider attacks
Credential abuse
Lateral movement
Data exfiltration
& more

How Does Network Detection and Response Work?

As suggested above, NDR works by integrating a set of detection, investigation, and response solutions to mitigate malicious activity in an organisation’s network.

Detection

Gathering data across an organisation’s various environments, NDR uses machine-led analytics to expose threats. For the most effective NDR solution possible, organisations can use multiple machine analytics, for example, scenario-based modelling for known tactics, techniques, and procedures (TTP) and deep inspection of traffic metadata against known indicators of compromise (IoC).

Investigation

NDR provides organisations with real-time network insights and analytics; it provides relevant, contextual information, which helps with the efficiencies of a team’s investigations into potential attacks. NDR solutions also provide network-based evidence, which allows the efficient identification of suspicious activity, making threat hunting easier.

Response

NDR solutions can also accelerate and automate an organisation’s security workflows utilising SOAR. This helps respond to potential threats become an automated process, allowing teams to focus on other security areas. Helping to reduce dwell time, NDR’s automated response to potential threats can lower manual intervention.

Does my Organisation Need an NDR Solution?

If an organisation already has Security Information and Event Management (SIEM) and Endpoint Detection and Response (EDR), the thought of including an NDR in the solution package may seem overkill.

However, Gartner has suggested that utilising all three of the solutions above can help create a Security Operations Centre (SOV) Visibility Triad, which helps to reduce the time threat actors are on an organisation’s network.
