Beyond the basics: Implementing an active defense
Summary: Cisco Talos describes active defense as the next stage of security maturity, in which defenders use threat intelligence and their own environment telemetry to hunt threat actors rather than waiting for detections to fire. The article notes that ransomware compromises involving data exfiltration are not fast, giving defenders a time window to hunt from the inside out, and it recommends quick wins including DNS query log analysis, high-priority triggers with near-zero false positives, root cause analysis of blocked endpoint threats, and tiered administrator accounts.
What you should know: Talos states the odds are against defenders: the hunter has limited time and resources, the target is unknown, and the activity being searched for is often undefined - so the time attackers spend finding databases and staging exfiltration is the window you either use or lose.
