Endpoint Detection and Response

Endpoint Detection and Response (EDR) is a cybersecurity technology that continuously monitors and collects data from endpoints (like computers, servers, and mobile devices) to detect, investigate, and respond to suspicious activities and threats. It uses behavioral analysis, machine learning, and threat intelligence to identify advanced threats that traditional antivirus might miss. EDR tools provide real-time visibility, automated response actions, and forensic capabilities to help security teams mitigate attacks.

Also known as: EDR, Endpoint Detection, Endpoint Security, Endpoint Threat Detection, Endpoint Protection

Why learn Endpoint Detection and Response?

Developers should learn EDR to enhance application security, especially when building or maintaining systems that handle sensitive data or are exposed to external networks, as it helps identify vulnerabilities and attack patterns. It's crucial for roles in DevSecOps, cloud security, or any environment requiring compliance with security standards like GDPR or HIPAA, where proactive threat detection is mandatory. Understanding EDR also aids in integrating security into the software development lifecycle (SDLC) to prevent breaches.
