The article “Vintage Detection: Applying RADAR Research from 1953 to Detect Modern Cyber Threats” explores how Signal Detection Theory, developed from 1950s military RADAR research, can enhance contemporary cybersecurity practices. This theory offers a statistical framework to distinguish meaningful signals (such as cyber threats) from background noise, addressing the balance between false positives and missed detections. By applying concepts like the likelihood ratio, security teams can adopt data-driven approaches to threat detection, moving beyond intuition. The article suggests operationalizing this framework through probabilistic risk-based alerting, optimizing detection strategies, prioritizing incident response, and developing strategic security metrics. This 70-year-old research provides valuable insights for modern security operations.

I’ll be digging into this topic a lot more - the article references one of the “foundational” signal detection theory papers, and I’m curious to see how it’s evolved over the years 
Seems so useful and I’m amazed I’ve not heard of it in the context of cybersecurity earlier!
