What is the primary function of EDR in cybersecurity?

• A. Detection of physical threats
• B. Endpoint Detection and Response
• C. Emergency Data Recovery
• D. External Device Regulation

Answer: (B)

The primary function of EDR, which stands for Endpoint Detection and Response, is centered around the proactive identification and mitigation of threats to endpoint devices within a network. EDR solutions continuously monitor endpoint activities to detect suspicious behavior, which helps organizations identify and respond to potential security incidents in real time.

EDR platforms gather and analyze data from endpoints—such as laptops, desktops, and servers—to detect anomalies that may indicate a breach or an ongoing attack. Once such activities are detected, EDR systems not only alert security teams but also provide tools for incident response, such as isolating affected systems, gathering forensic data, and implementing remediation actions to contain and remediate the threat.

This capability is critical in modern cybersecurity strategies, as endpoints are often the targets of cyberattackers looking to exploit vulnerabilities. By leveraging EDR, organizations can enhance their security posture while ensuring they can respond quickly to emerging threats, significantly reducing the potential damage caused by breaches.

The other options focus on different themes that are not directly associated with the specific and focused role of EDR in cybersecurity. For instance, detection of physical threats pertains more to physical security measures rather than cybersecurity, while emergency data recovery deals with data loss scenarios rather than real-time threat detection. External device regulation is more
