Threat Detection and Response

This article explains Threat Detection and Response (TDR) as a reactive cybersecurity approach, detailing goals (early detection, rapid response, continuous monitoring), key components (ITDR, SIEM, EDR, threat intelligence, AI/ML), and an implementation roadmap, while noting limitations such as alert overload and the risk of advanced threats evading detection. It highlights the role of Managed Detection and Response (MDR) for 24/7 monitoring, incident response, and cost-effective expertise, and promotes ThreatLocker’s Zero Trust endpoint controls—Application Allowlisting and Ringfencing—to reduce attack surface and strengthen overall security posture.
