The Defender's Modern Stack

• EDR / XDR (Endpoint / Extended Detection and Response): continuous telemetry (process trees, command lines, network, file, registry) with behavioral detection and response actions — far beyond signature AV.
• Behavioral detection and ML: catch what malware does (shadow-copy deletion, LOLBin chains, injection), not just known bytes. ML helps at scale, but generates false positives — analysts still triage.
• Threat intelligence sharing:
• MITRE ATT&CK: common language of adversary tactics and techniques.
• STIX / TAXII: standard formats/transport for sharing threat intel.
• IOCs and YARA at scale: hunt across the whole fleet, not one file.
