What is Threat Detection and Reponse?

by Dallon Robinette | Mar 07, 2024 | Back to Basics

When assessing the options available, it can be difficult to understand the nuances between various cybersecurity systems. This is especially true for threat detection and response (TDR) systems such as network detection and response (NDR), endpoint detection and response (EDR), and Extended Detection and Response (XDR). This blog post will explore the concept of threat detection and response, and provide a basic understanding of how these three different systems support the goal of TDR systems.

What is Threat Detection and Response?

In cybersecurity, threat detection and response (TDR) is not only a group of products but also a proactive approach to how organizations identify and respond to cyber threats. Threat detection and response tools — such as NDR, EDR, and XDR — continuously monitor networks, systems, and digital assets to identify and respond to potential security breaches and cyberattacks.

An organization that centers its cybersecurity strategy around threat detection and response tools typically recognizes that it is not possible to prevent all cyber threats. Instead, they would use a threat detection and response tool or a combination of tools to not only proactively search for threats but also to detect both known malicious and potentially malicious activity and respond accordingly to minimize damage and mitigate the risks of those threats.

What are 3 examples of threat detection technology and how do they work?

There are three primary threat detection and response solutions: network detection and response (NDR), endpoint detection and response (EDR), and extended detection and response (XDR). While there is some overlap in certain use cases for these systems, each is unique in how they detect and respond to threats.

Network detection and response (NDR): NDR solutions evolved from legacy intrusion detection/prevention (IDS/IPS) systems to provide comprehensive visibility into network traffic, enabling real-time detection and response to potential threats. In addition to standard IDS features like signature-based detection and deep packet inspection, many NDR systems also leverage advanced analytics, machine learning, and behavioral analysis techniques to detect anomalies, identify malicious activities, and prioritize alerts for efficient incident response.

Endpoint detection and response (EDR): EDR solutions have emerged to address the need for enhanced visibility and control at the endpoint level. These solutions monitor and analyze endpoint activities — including file and process behaviors, registry changes, and network connections — to detect and respond to advanced threats that may evade traditional antivirus solutions.

Extended detection and response (XDR): XDR is the newest threat detection and response system, expanding on the capabilities of SIEM (security information and event management) and SOAR (security orchestration, automation, and response) systems to integrate multiple security components and data sources across networks, endpoints, and cloud environments. XDR solutions seek to leverage advanced correlation and analytics capabilities to provide comprehensive threat detection and response across various security domains.

Why is threat detection and response important?

Threat detection and response is important in cyber security because TDR solutions do the following:

  • Mitigate Evolving Threats: Cybercriminals are constantly developing new tactics. Threat detection and response solutions stay up to date by using threat intelligence and anomaly detection to identify both known and unknown threats. This adaptability is vital to ensuring an organization’s safety in an ever-evolving threat landscape.
  • Automate Response: Many threat detection and response tools can automate some response actions, saving valuable time. For instance, some TDR solutions can isolate infected devices, block malicious traffic, or patch vulnerabilities, preventing the threat from spreading and causing further damage.
  • Improve Security Posture: Threat detection and response solutions can provide valuable insights into your security posture. By analyzing past incidents and identifying vulnerabilities, you can strengthen your defenses and proactively address weaknesses before attackers exploit them.
  • Reduce Costs: A successful cyberattack can be incredibly expensive, resulting in data loss, downtime, and regulatory fines. Threat detection and response tools can help prevent such scenarios, significantly reducing the financial impact of security breaches.
  • Improve Decision-Making: Threat detection and response solutions provide security teams with real-time data and threat context, allowing them to make informed decisions during an incident. This can mean prioritizing critical systems, allocating resources effectively, and containing the threat with greater precision.

What is the right threat detection and response option for my organization?

Unfortunately, there's no one-size-fits-all answer to choosing the right threat detection and response (TDR) option for your organization. The ideal solution depends on several factors specific to your business. Here are two things to consider before making a decision:

  • Security Needs & Budget: Identify your most critical security needs. Are you primarily concerned with malware protection, insider threats, or targeted attacks? Budget is also crucial. Managed Detection and Response (MDR) services could offer comprehensive solutions but come at a premium, while some on-premise TDR tools may require significant expertise to manage.
  • IT Infrastructure: Consider the complexity of your IT environment. An NDR solution could be a great option for an organization with a hybrid or cloud-heavy infrastructure. For organizations with numerous endpoints, an EDR might provide the desired visibility. It is important to choose a TDR solution that is best suited for your organization’s unique environment.

Once you have identified the right type of threat detection and response for your organization, you can begin to evaluate the different solutions available.

Stamus Security Platform for Threat Detection and Response

Network detection and response is not just another cyber security tool; it is a strategic asset that fortifies defenses, enhances visibility, and empowers organizations to navigate the complexities of modern cyber threats with resilience and efficacy.

If you are considering threat detection and response solutions, you should consider NDR. There are a lot of NDR options to choose from, and that choice can make a large impact on your organization’s cyber security posture. Stamus Networks is a global provider of high-performance network-based threat detection and response (NDR) systems. Our solution, the Stamus Security Platform, helps enterprise security teams know more, respond sooner, and mitigate threats.
