Security Operations

Purple teaming is a collaborative exercise where offensive (red) and defensive (blue) teams work together to emulate attacker techniques and measurably improve detection and response. What it is, how it differs from red teaming, and a step-by-step way to run one.

SIEM collects and correlates security logs to detect threats; SOAR automates the response with playbooks. How they differ, whether you need both, and where Splunk, XDR and MDR fit.

A SOC maturity model like SOC-CMM measures how developed your security operations are — from ad hoc alert-chasing to proactive, automated and threat-informed. The dimensions to assess and how to improve.

A defensive threat-intelligence explainer on the venue types that power the ransomware economy - forums, RaaS portals, initial-access brokers, leak sites - and how defenders and law enforcement monitor and disrupt them.

Inside the operational security ransomware operators use to stay anonymous, and the recurring OPSEC mistakes, blockchain tracing, infrastructure seizures and leaks that keep unmasking them anyway.

Lessons from wiring up a D2D multi-agent system to a production SOC: the PagerDuty integration, the human review queue, what broke, and what surprised us.
