Security & SOC — field notes from production detection.
SIEM, XDR, SOAR, and SOC engineering from the perspective of teams that have to defend their decisions in front of auditors and regulators.
What you need to know about security & soc
Security Operations Centers face a structurally hard problem: the volume of telemetry a modern enterprise generates exceeds what any analyst team can process manually, but the cost of a missed detection is catastrophic. Extended Detection and Response (XDR) platforms address this by correlating signals across endpoints, network, cloud, and identity — but correlation logic that works in a test environment often produces false positives at scale that erode analyst trust. The discipline of threat-informed detection, using frameworks like MITRE ATT&CK, creates detection content that is explicit about what attacker behaviour each rule targets. AiRAT's security engineering notes cover SIEM architecture, XDR deployment patterns, SOC automation, and the evidence and auditability requirements that enterprise and regulated financial institution SOC teams face in practice.
