What Is EDR? Endpoint Detection and Response Guide

What is Endpoint Detection and Response (EDR)?

Endpoints refer to physical or end-user devices that connect to the computer network. Examples include laptops, desktops, mobile phones, virtual machines, and the Internet of Things (IoT). Endpoint Detection and Response (EDR) is the cybersecurity technology that helps prevent threats to compromise the functionality and security of endpoints.

It does so by detecting threats across the environment, gaining detailed information on them, and accordingly handling them by performing automated actions to mitigate them.

EDR solutions also alert security professionals to gain insights into the breach's source, mechanism, and impact. Security analysts review EDR security data for manual intervention. It involves designing future procedures for handling and ensuring complete threat neutralization.

Watch the video below for an in-depth explanation of Endpoint Detection and Response (EDR)!

How Does EDR Work?

Now you know what Endpoint Detection and Response is, let’s proceed to learn about the generalized depiction of how EDR works:

1. Continuous Monitoring and Data Collection

EDR technology involves installing the software agent on all digital devices for effective, round-the-clock monitoring. Such devices are managed devices, and the relevant activities are logged. These activities are further shared with the EDR solution on the cloud or on-premises.

They are sent to security teams to monitor regular activity and analyze complex or unclear ones. It allows real-time updates and provides key details such as event logs, application use, authentication attempts, and other information.

2. Behavioral Baseline and Anomaly Detection

Owing to the automatic detection and preliminary measures, the data is analyzed by the EDR solutions via AI and Machine Learning, which interprets the data. The aim is to distinguish the usual and unusual activities based on patterns and other methods. The data is compared with global threat intelligence to discover anomalies and other relevant warning signs or existing or potential threats.

3. Real-time Threat Response

The EDR, on identification of suspicious activity, responds by taking certain automated actions, such as endpoint isolation or halting a process. It helps contain the threat, minimize the damage, and prevent further spread. It also alerts human security teams, which analyze the data to decide the appropriate action.

4. Role of Human Analysts Alongside AI/ML

Besides the AI/ML action of containing the data, human analysts dive deep into the threat’s origins and strategize its handling. They review alerts, analyze the data stored by EDR solutions, investigate the same, identify root causes, and gain more relevant details to enhance future responses. If repeated, they ensure enhanced security for the timely and accurate detection of such attacks.

Key Features of EDR Solutions

Capable of offering effective security, the definition of what is EDR in security is determined by the following key features:

1. Behavioral Analysis

One of the quality features of EDR is behavioral analysis. It involves pattern, activity, and trend analysis among users and programs to identify the changes or modifications in activity. It works through algorithms, ML, and statistical analysis to detect abnormalities and take appropriate actions. The integrated technologies with the analysis help gain detailed information on the attack while quickly acting to resolve it.

2. Threat Hunting 

Proactive threat hunting is an otherwise manual practice for effective security. However, EDR automates the same by using forensic data to find the Indicators of Compromise (IOC). It helps detect potentially malicious files, configurations, and suspicious behaviors, thus reducing possible damage.

Certain EDRs may also allow users to design customized rules for active hunting against a specific type of threat at specific times.

3. Incident Response Automation

Detecting a threat isn’t the only requirement for any security solution. Effective and rapid automated incident response is crucial to preventing the threat. EDRs are designed to do the same by containing the threat through the isolation of the affected endpoint. They also block traffic between the network and the endpoint of concern and alert the security teams.

Additionally, it offers key information about endpoint activities, threat impact, and other aspects that help identify the attack's origin. The task contributes to defining effective strategies for handling such attacks.

4. Real-Time Monitoring and Reporting

The EDR-based protection remains active around the clock. It constantly checks for activities and offers continuous and immediate visibility into endpoint activity. It looks at various data sources, analyses the data, and detects the threats. The detection relies on signature-based and behavioral analysis to identify the malware and new threats, offering updated protection.

These are managed as mentioned and simultaneously alerted for more effective handling by the human team. The reports are generated considering the minimal presence of false positives by distinguishing between genuine and fake threats.

5. Integration with Existing Security Infrastructure

EDR solutions can integrate with different threat intelligence feeds, tools, and existing Security Information and Event Management (SIEM) products, thus upgrading security to a higher level. They allow for gaining the latest information with an enhanced detection mechanism.

6. Scalability for Organisations

The feature is cost and time-effective for businesses aiming to scale their business. EDR solutions allow easy management of an increase in endpoints, such as additional devices and employees. It all comes without compromise in the efficiency of security that the technology provides.

7. Intuitive User Interface and Usability

Easy management of EDR solutions is possible with user-friendly dashboards. It prevents additional cost and time for training employees in the usage methods. The interface also reduces the possibility of ignorance of any incident attack while enabling easy software management.

Benefits of Implementing EDR

The EDR implementation helps upgrade the security of the devices. But that's just the surface. The benefits are deep, and here they are listed:

• Offers regular and advanced updates: Implementation of EDR is associated with continuous monitoring with the help of AI and ML. This means that security always remains active to offer quality protection from cyberattacks.
• Provides timely response: Preliminary measures are the best protection against irreversible harm. EDR helps achieve this by alerting the team while taking basic actions to minimize the potential damage. Further, the active hunt for vulnerabilities, Indicators of Compromise (IOC), and other possible entry points is constantly conducted to ensure timely action.
• Offers in-depth insights: EDR is an effective solution for helping understand how an attack occurs. In incidents associated with removing harmful files, it provides details of threat cases and visual attack chains. The attack pathway helps in root cause analysis and future prevention.
• Saves unnecessary panic: The efficiency of EDR allows focus only on important suspicious activities. The irrelevant or non-malicious ones are already filtered out before investigation to save time and reduce alert fatigue.
• Ensures unhindered workflow: The effective functionality prevents cyber attacks, allowing for the smooth operation of all business tasks.

Why is EDR Important?

Taking measures to prevent a threat is undoubtedly an effective way. However, ensuring complete prevention of a cyberattack is impossible. Every organization must be updated in real time and take accurate and timely actions. Determining the path, method, and entry mechanism is crucial, yet it is lacking in conventional threat prevention systems. EDR makes this possible.

Further, imparting protection from common yet dangerous threats like phishing, DDoS attacks, and others can be challenging without intelligent threat detection and response systems. The threats increase more in remote working environments, where protecting the main systems or services from possible threats worldwide is highly challenging. The evolution of these threats requires updating global data and advancing in attack handling methodologies, all of which are part of the mechanism of EDR.
