From IDS to NDR: How Network Security is Evolving to Counter New Threats

In the current state of cyber security, how quickly you detect and respond to threats is not just a bonus but a necessity as well. With increasing risks corresponding measures should also be strengthened for organizational cyber security. Conventional Intrusion Detection Systems (IDS) are traditional in nature and have worked as a barrier in some ways, but they are not equipped with the next-generation features to combat sophisticated and new-age threats. That is where Network Detection and Response (NDR) , a solution based on IDS foundations comes into play with modern features of modern networks.

This article will discuss the journey from IDS to NDR and the characteristics of NDR and how it helps address the increasing needs of cybersecurity.

As opposed to IDS that operates based on known attacks signature database, NDR relies on machine learning and behavioral analysis. Here’s a closer look at the primary capabilities that set NDR apart:

• Behavioral Analytics: While traditional NDR tools focus on patterns of threats, the current system employs machine learning for behavior analysis, where it can discover unidentified threats from abnormally performing nodes.
• Real-Time Incident Response: NDR solutions are not only capable of reporting suspicious incidents to the security teams; they can also self-act on the same. For example, they may quarantine affected endpoint or eliminate aggressive traffic to minimize the proliferation of threats and containing the harms.
• Threat Intelligence Integration: The NDR tools are further configured to be updated with the latest threat intel information regularly. This is because it assists them to detect and counter what are current and probable sophisticated threats within cyber space.
• Complete Visibility: NDR looks at all network traffic and gives an overall view of the network’s activity including encrypted communication, cloud activities among other areas that IDS usually does not cover. This kind of visibility makes sure that no threats that can pose a threat to the organization are left unnoticed.

How NDR Works to Identify Threats Fast

To properly address superior cyber threats, NDR solutions are always collecting data, evaluating network activity, and addressing problems. The process typically includes:

• Data Gathering: NDR gathers information from network devices and computers, servers and cloud systems, and brings all of it to a single interface for viewing.
• Behavior Analysis: After compilation or data acquisition by the system, it goes further to build up baseline measures against identified network behaviors. If there is something different and goes against these norms, then there is always going to be a second look at it.
• Advanced Detection: NDR uses a known approach and an unknown approach; it searches for evidence of a suspected incident and seeks to find deviant patterns to capture a known threat and to discover unknown threats.
• Automated Response: In the case of threat detection , NDR can handle it immediately, and in an automated manner, for instance, remove infected segments to reduce the risk of more havoc.

Performance comparison: NDR vs IDS

When examining NDR versus IDS, it becomes clear that NDR offers more advanced features essential for today’s network security requirements:

• Detection Methods: IDS is based on the pattern, while NDR contains both the base of pattern recognition and behavioral analysis, and the identification of unknown threats is more effective.
• Response Capabilities: IDS is usually used to notify the security team of incidents but does not contain the ability to respond inherently, while NDR is used to respond to threats directly and to minimize and control incidents in real time.
• Network Insight: NDR offers more extensive information on the network activities with reference to encrypted data than IDS having difficulty decoding it.

Advantages of integration between NDR and IDS

With the NDR, there are several strong features available reliably; however, IDS and Intrusion Prevention Systems (IPS) enable it to build multiple layers for the detection and response strategy. Here are some of the benefits of this approach.

• Enhanced Detection: The integration of IDS and NDR is the ability to channel the combination of pattern-based detection from IDS with behavioral analysis from NDR and increases the rate of detection of both known and unknown threats.
• Comprehensive Response: IDS is therefore more of an alarm system that notifies security teams to threats whereas; NDR has measures to counter such threats making it a more vigorous defense system.
• Reduced False Positives: IDS regarding alerts and NDR to help organizations minimize false positive incidents and clear for security specialists.
