Network Detection & response

What is Network Detection and Response (NDR)?

What is NDR and why do you need it? In today's digital landscape, cyberthreats are more sophisticated than ever. Traditional security measures, like firewalls, antivirus and other endpoint protection software (EDR), are no longer sufficient to protect against these advanced attacks.

This is where NDR comes into play. NDR is short for Network Detection and Response.

Understanding NDR

Network Detection and Response (NDR) is a cybersecurity solution designed to provide comprehensive visibility and protection across a network. It focuses on detecting malicious activities and responding to them in real-time. Unlike traditional cyber security tools that rely on predefined rules and signatures, Network Detection and Response (NDR) uses advanced techniques like machine learning (ML) and artificial intelligence (AI) to identify and respond to threats that may go unnoticed by conventional methods.

How does NDR work?

NDR solutions continuously monitor network traffic and analyze patterns to detect anomalies that could indicate a security threat.
Here’s a step-by-step overview of how a Network Detection and Response (NDR) solution operates:

Detection

NDR systems scan network traffic for unusual behavior, such as unauthorized access attempts, SMB rename, data exfiltration, or lateral movement within the network. These detected activities often signal the presence of an attacker.

Prioritization

Once a potential threat is detected, NDR solutions prioritize these alerts based on their severity and potential impact. This helps security teams focus on the most critical threats first, reducing the noise from false positives.

Investigation

Security analysts can delve into detailed alert notifications and reports generated by Network Detection and Response (NDR) tools to understand the nature of the threat. This involves tracking the attacker’s actions and identifying affected systems and data.

Response

Based on the investigation, NDR solutions provide actionable insights and automated responses to mitigate the threat. This can include isolating compromised devices, blocking malicious traffic, and deploying patches to vulnerable systems.

Benefits of Network Detection & Response (NDR)

Enhanced Visibility: By continuously monitoring network traffic, NDR provides deep visibility into network activities, helping identify threats that bypass other security measures.

Early Detection: Network Detection and Response (NDR) can detect early signs of an attack, such as unusual traffic patterns or unauthorized access attempts, allowing for a swift response before significant damage occurs.

Reduced Alert Fatigue: By prioritizing alerts based on their severity, NDR helps security teams focus on genuine threats.

Automated Responses: Network Detection and Response (NDR) solutions often include automated response capabilities, which prevent or help contain and mitigate threats quickly without human intervention.

Why Does My Company Need Network Detection and Response (NDR)?

In the current cyber threat landscape, every company, regardless of size or industry, is a potential target for cyberattacks. Here are some key reasons why your company needs NDR:

Evolving Threats (Zero day): Cyber threats are constantly evolving, with attackers using sophisticated methods and unknown vulnerabilities to breach networks. Network Detection and Response (NDR) provides the advanced detection capabilities needed to identify and counter these threats, based on the network traffic activity indicators, that the hacker cannot avoid leaving behind.

Regulatory Compliance: Many industries are subject to strict data protection regulations. NDR helps ensure compliance by providing comprehensive monitoring, as well as detailed forensics and reporting capabilities.

Incident Response: Quick detection and response to security incidents are crucial to minimize damage. Network Detection and Response (NDR) enables rapid response, reducing the time attackers have to cause harm.

Protection of Sensitive Data: For companies handling sensitive data, such as customer information or intellectual property, NDR provides an additional layer of security to protect this valuable data from breaches. An example of this could be the detection of network activity, relating to the exfiltrating intellectual property data, by malicious insiders.

What Are Managed NDR Solutions?

Managed NDR solutions are services provided by third-party vendors that take over the monitoring, detection, and response functions of NDR for a company. Here’s why they are beneficial:

Expertise: Managed NDR services bring in cybersecurity experts, who are skilled in detecting and responding to threats. This is particularly useful for companies that lack in-house cybersecurity expertise.
24/7 Monitoring: Managed NDR providers offer round-the-clock monitoring, ensuring that threats are detected and responded to at any time, day or night. This is often called managed detection and response (MDR).
Cost-Effective: Outsourcing Network Detection and Response (NDR) functions can be more cost-effective than building and maintaining an in-house team, especially for smaller companies.
Advanced Technology: Managed NDR providers often use the latest technologies and methodologies, ensuring that the company's network is protected by cutting-edge solutions. MDR providers will often integrate the NDR solution with an EDR and SIEM system.
