The Importance of Network Detection and Response Systems: A Closer Look at Corelight's Investigator

Network detection and response (NDR) systems are essential for any organization looking to enhance its cybersecurity capabilities. In this article, we'll explore the benefits of using an NDR system like Corelight's Investigator, including its ability to detect complex attacks and provide actionable insights and recommendations for mitigating threats.

The world of cybersecurity is constantly evolving, with new threats emerging every day. As a result, organizations need to stay ahead of the curve when it comes to protecting their networks and data. One way to do this is by implementing a network detection and response (NDR) system, such as Corelight's Investigator.

NDR systems are designed to provide deep visibility across networks, allowing security teams to detect intrusions and anomalies in real-time. They integrate with existing Security Information and Event Managers (SIEMs), endpoint detection and response (EDR) solutions, and firewalls to gather, enrich, and correlate network data with widespread events.

In this article, we'll take a closer look at Corelight's Investigator software, which is part of its Open NDR Platform. We'll explore how it works, its benefits, and why it's an essential tool for any organization looking to enhance its cybersecurity capabilities.

Corelight's Investigator is designed to be user-friendly, even for junior analysts. This makes it an ideal solution for organizations that want to improve their threat hunting skills without breaking the bank. The software comes pre-loaded with a sample network traffic, allowing users to get hands-on experience with NDR systems.

But how does Investigator work? Simply put, it provides deep visibility across networks by analyzing and correlating vast amounts of network data. This allows security teams to identify potential threats before they become full-blown incidents.

One of the key benefits of using an NDR system like Corelight's Investigator is its ability to detect complex attacks that might evade traditional security solutions. By providing a 360-degree view of the network, these systems can help identify vulnerabilities and misconfigurations that could lead to breaches or outages.

But how does it do this? Simply put, Investigator uses advanced analytics and machine learning algorithms to analyze network traffic and identify potential threats. This includes analyzing DNS requests, web host interactions, custom DNS providers, and cloud data stores – all of which can be critical in understanding the inner workings of an exploit.

Another key benefit of using an NDR system like Corelight's Investigator is its ability to provide actionable insights and recommendations for mitigating threats. By analyzing network traffic and identifying potential vulnerabilities, these systems can help security teams respond faster and more efficiently.

But how does it do this? Simply put, Investigator provides a comprehensive view of the network, allowing security teams to identify areas where threats are emerging and develop targeted response strategies. This includes providing recommendations for blocking traffic from specific IP addresses or adding new threat intelligence feeds.

In addition to its ability to detect complex attacks and provide actionable insights, Corelight's Investigator is also highly customizable. Organizations can easily add integrations with other security solutions, such as SIEMs, EDR tools, and firewalls – making it an ideal solution for organizations looking to enhance their cybersecurity capabilities.

So how does one get started with using a network detection and response system like Corelight's Investigator? The good news is that it's relatively easy. Simply sign up for a free trial or demo, and you'll have access to all of the features and functionality of the software.

The bad news is that investing in an NDR system like Corelight's Investigator requires a significant upfront cost. However, this investment can pay dividends in terms of improved cybersecurity capabilities and reduced risk of breaches and outages.

In conclusion, network detection and response systems are an essential tool for any organization looking to enhance its cybersecurity capabilities. By providing deep visibility across networks, these systems allow security teams to detect intrusions and anomalies in real-time – giving them a critical advantage when it comes to protecting their networks and data.
