What Is Endpoint Detection and Response (EDR)?

Endpoint detection and response (EDR), also known as endpoint threat detection and response (ETDR), is an integrated endpoint security solution that combines real-time continuous monitoring and collection of endpoint data with rules-based automated response and analysis capabilities. The term was suggested by Anton Chuvakin at Gartner to describe emerging security systems that detect and investigate suspicious activities on hosts and endpoints, employing a high degree of automation to enable security teams to quickly identify and respond to threats.

The primary functions of an EDR security system are to:

  • Monitor and collect activity data from endpoints that could indicate a threat
  • Analyze this data to identify threat patterns
  • Automatically respond to identified threats to remove or contain them, and notify security personnel
  • Forensics and analysis tools to research identified threats and search for suspicious activities

Adoption of EDR solutions


Adoption of EDR is projected to increase significantly over the next few years. According to Stratistics MRC's Endpoint Detection and Response - Global Market Outlook (2017-2026), sales of EDR solutions—both on-premises and cloud-based—are expected to reach $7.27 billion by 2026, with an annual growth rate of nearly 26%.

One of the factors driving the rise in EDR adoption is the rise in the number of endpoints attached to networks. Another major driver is the increased sophistication of cyberattacks, which often focus on endpoints as easier targets for infiltrating a network.

Key components of EDR security


EDR security provides an integrated hub for the collection, correlation, and analysis of endpoint data, as well as for coordinating alerts and responses to immediate threats. EDR tools have three basic components:

Endpoint data collection agents. Software agents conduct endpoint monitoring and collect data—such as processes, connections, volume of activity, and data transfers—into a central database.

Automated response. Pre-configured rules in an EDR solution can recognize when incoming data indicates a known type of security breach and triggers an automatic response, such as to log off the end user or send an alert to a staff member.

Analysis and forensics. An endpoint detection and response system may incorporate both real-time analytics, for rapid diagnosis of threats that do not quite fit the pre-configured rules, and forensics tools for threat hunting or conducting a post-mortem analysis of an attack.

  • A real-time analytics engine uses algorithms to evaluate and correlate large volumes of data, searching for patterns.
  • Forensics?tools?enable IT security professionals to investigate past breaches to better understand how an exploit works and how it penetrated security. IT security professionals also use forensics tools to hunt for threats in the system, such as malware or other exploits that might lurk undetected on an endpoint.

New EDR capabilities improve threat intelligence


New features and services are expanding EDR solutions' ability to detect and investigate threats.

For example, third-party threat intelligence services, such as 买足球平台哪个比较好 Global Threat Intelligence, increase the effectiveness of endpoint security solutions. Threat intelligence services provide an organization with a global pool of information on current threats and their characteristics. That collective intelligence helps increase an EDR's ability to identify exploits, especially multi-layered and zero-day attacks. Many EDR security vendors offer threat intelligence subscriptions as part of their endpoint security solution.

Additionally, new investigative capabilities in some EDR solutions can leverage AI and machine learning to automate the steps in an investigative process. These new capabilities can learn an organization's baseline behaviors and use this information, along with a variety of other threat intelligence sources, to interpret findings.

Another type of threat intelligence is the Adversarial Tactics, Techniques, and Common Knowledge (ATT&CK) project underway at MITRE, a nonprofit research group that works with the U.S. government. ATT&CK is a knowledgebase and framework built on the study of millions of real-world cyberattacks.

ATT&CK categorizes cyberthreats by various factors, such as the tactics used to infiltrate an IT system, the type of system vulnerabilities exploited, the malware tools used, and the criminal groups associated with the attack. The focus of the work is on identifying patterns and characteristics that remain unchanged regardless of minor changes to an exploit. Details such as IP addresses, registry keys, and domain numbers can change frequently. But an attacker's methods—or "modus operandi"—usually remain the same. An EDR can use these common behaviors to identify threats that may have been altered in other ways.

As IT security professionals face increasingly complex cyberthreats, as well as a greater diversity in the number and types of endpoints accessing the network, they need more help from the automated analysis and response that endpoint detection and response solutions provide.
