What Is EDR?

EDR (endpoint detection and response) is a layered endpoint security solution that combines real-time constant monitoring and endpoint activity data collection with rule-based automated response and analysis techniques. This integrated approach aims to identify potential cyber security threats, remove or contain incidents, further investigate and provide necessary remediation guidance to restore affected systems.

The term was first coined by Gartner’s Anton Chuvakin in July 2013. Chuvakin defined endpoint threat detection and response as “the tools primarily focused on detecting and investigating suspicious activities (and traces of such) on hosts/endpoints.”

EDR helps to:

• Detect threats penetrating your security environment by examining each file interacting with endpoints via continuous file analysis.
• Contain malicious files and prevent threats from spreading further by isolating potentially compromised hosts from adjacent network activity, preventing infiltration.
• Investigate threat behavior to identify vulnerabilities and utilize the information for addressing future threats.
• Eliminate threats by gathering actionable data on its entire timeline and execute an action plan for remediating systems to their original clean state.

General Purpose

Every endpoint device connecting to an organization’s network forms a porous security perimeter, making it highly susceptible to data breaches and malicious attacks. Modern and sophisticated threats such as file-less malware, polymorphic malware, phishing, advanced persistent attacks and hidden malicious code in HTTPS traffic can easily evade the security perimeter and expose critical assets to hackers.

Additionally, the COVID-19 pandemic has brought a tremendous shift of business data and processes to online infrastructure and remote working, increasing vulnerabilities and loopholes in security environments. This transformation has resulted in an exponential rise of sophisticated attacks. A report by Verizon found a 13% increase in ransomware attacks. This jump is greater than the past five years combined.

Ransomware attacks have become one of the biggest security challenges organizations worldwide face. Cybercriminals steal sensitive data and hold it hostage, demanding cryptocurrency or similar compensation in exchange. Businesses face the risk of not only losing data but having it shared with the public.

These challenges demand an elaborate security strategy, and this is where EDR solutions can help. They provide the granular visibility and control required to safeguard endpoints before and after infection using automated analysis and response.

Key Components

Endpoint Data Collection and Threat Detection

The first step of an EDR security solution involves monitoring and collecting endpoint and network event data such as connections, processes, activity volume and data transfers. Software agents that monitor host systems record this information into a central database where other events occur.

This process helps EDR with its primary job — threat detection. With the help of cyber threat intelligence, you can detect threats that frequently change their characteristics.

Automated Response and Containment

It utilizes behavioral analytics to analyze several incidents by different users in real time and detect traces of suspicious activities automatically. Through continuous file analysis, pre-configured rules generate automated actions on identifying a security breach and trigger an immediate response like sending alerts or logging the end user off. EDR also helps contain the threat and stop it from spreading and infecting other systems.

Data Analysis and Threat Hunting

The process also includes real-time analytics for the rapid diagnosis of threats that don’t correspond to pre-configured rules. Analytics engines utilize algorithms to search for patterns by evaluating and correlating large volumes of data. Users then receive next steps suggestions if a confirmed threat threatens an endpoint. False positives trigger threat cancellation, and the information is recorded to tackle future threats.

Forensic tools are utilized for threat hunting or conducting attack analysis. IT professionals can hunt for threats like malware or other undetected exploits on an endpoint and further investigate breaches to understand their behavior.

Threat Elimination

Lastly, EDR creates an action plan to eliminate threats. There are several issues to consider before implementing the elimination strategy, like figuring out the nature and origin of the threat, pinpointing affected systems and ensuring the threat has not replicated itself. You can collect endpoint security-specific telemetry to enhance visibility into the threat’s behavior, helping eliminate it efficiently.

Every EDR security tool doesn’t work the same way, but each performs essential functions with a similar objective to proactively monitor, analyze, identify, detect and prevent advanced threats.

Fundamental Capabilities

Provides Visibility Throughout the IT Environment

Complete endpoint visibility is the most crucial capability that EDR offers, making it an essential component of any security environment. It enables constant endpoint monitoring, either online or offline. Through a centralized management console, continuous monitoring provides comprehensive insights into all endpoints to view suspicious activities and stop them before they become breaches.

Data Collection To Create a Threat Repository

A team of security experts collects massive amounts of telemetry from endpoints, enriched with context. This data can address possible irregularities using technologies like advanced analytics, artificial intelligence or machine learning. The assembled information is also stored in a database for further analysis and investigation so that it can be mined for signs of future attacks.

Behavioral Protection

EDR applies behavioral approaches to protect against emerging unknown threats, zero-day attacks and insider threats by searching for indicators of attack (IOAs). This feature tracks lateral movement across networks and resources, making it superior to traditional signature-based detection techniques or indicators of compromise (IOCs) methods that can cause a silent failure and lead to data breaches.

Enable Real-time Responses

An immediate and accurate response to a potential threat can prevent it from compromising your security infrastructure. The real-time response feature of EDR solutions can stop an attack in its initial stages by automatically triggering an action to contain or neutralize the threats. Rapid incident response allows you to limit cyberattack impacts and secure your business from full-blown breaches.

The Usage of Whitelists and Blacklists

EDR security systems incorporate whitelisting and blacklisting features, providing the ability to allow specific applications that run on a system or block suspicious domains, URLs and IP addresses. These options act as the first line of defense to ensure network safety against cybercriminals’ known modus operandi.

Primary Benefits

Detection of Endpoint Threats

EDR is designed to identify tactics, techniques and procedures used by attackers to invade your security perimeter. It gathers information on how attackers penetrate a network and their path of activity. The right EDR tools protect you against suspicious user activities and behavior, advanced malware, fileless attacks and misuse of legitimate applications.

More Cost and Time Efficient

These tools manage threats as soon as they enter an organization’s periphery, preventing disruptions, impact on productivity and financial losses. They automate detection, path analysis and lateral movement steps, eliminating human intervention. These initial automated phases allow security analysts to invest more time examining legitimate threats due to the presence of fewer alerts and false-positives.

Integration With Other Security Tools

Some highly advanced EDR systems can integrate with multiple security tools to deliver an extensive data security strategy. These integrations generate automated threat responses to instantly remove the detected malware via a third-party anti-malware program, avoiding delay in the user’s immediate actions.

Combines With Threat Intelligence

Many EDR vendors incorporate threat intelligence subscriptions in their endpoint security solution to expand their ability to identify the latest exploits, such as zero-day and multi-layered attacks. Cyber threat intelligence leverages AI and threat databases with data on past and currently evolving attacks, analyzes them and utilizes the information to detect threats targeting your endpoints.

Trends

Artificial Intelligence and Machine Learning Integration

Investigating threats is one of the most important features of EDR security systems. EDR can adopt machine learning and AI to provide automated investigation services.

AI allows you to track and learn the organization’s baseline threat behavior and use that information to analyze incidents. Machine learning helps identify threats and attack classes efficiently.

Adoption of the MITRE ATT&CK Framework

The Adversarial Tactics, Techniques, and Common Knowledge (ATT&CK) is a knowledge base developed with threat intelligence, real-world observations and incident reporting. It helps classify threats based on system vulnerabilities, malicious software programs and tactics used to infiltrate systems.

The adversary tactics, techniques and procedures (TTP) method used by ATT&CK for threat analysis has made it popular across the world.

Increasing Usage of BYOD Policies and IoT Devices

There has been a paradigm shift of business data, processes and infrastructure towards cloud computing in recent years. Poorly secured and misconfigured cloud resources act as a potential entry point for attack vectors. Along with cloud adoption, a rapidly evolving mobile technology, BYOD (bring your own device) practices and increased usage of IoT devices for greater flexibility has contributed to a significant rise in cyber threats worldwide.

According to a study by Allied Market Research, the global EDR market is estimated to reach $18.3 billion by 2031, registering a CAGR of 25.3% from 2022 to 2031. This growth is driven by growing enterprise mobility, increasing instances of targeted endpoint attacks and the need to mitigate digital security risks.

EDR vs. EPP

Both EDR and EPP (endpoint protection platform) protect endpoints against threats, but they fulfill different purposes. EPP acts as the first line of defense and focuses primarily on protecting against known and unknown malware attacks on your endpoints. At the same time, EDR acts as a second protective layer that helps identify and respond to threats that circumvent EPP or other security platforms.

These systems can be used separately as standalone solutions or united as a single solution to face complex cyber threats. Many vendors offer a combination of both EPP and EDR capabilities to provide comprehensive protection to your digital perimeter against ever-evolving security issues and cyber threats.
