Security Incident Command

Command and manage an active security incident from declaration through remediation handoff using the incident management framework (Google's IMAG, derived from ICS). Use when: you have a confirmed or suspected security incident and need to take command; someone says "we have a security incident" or "we may have been compromised"; you need to stand up an incident command structure with staffing roles; you are running forensic investigation and need to coordinate parallel tracks; an incident has grown large enough to require shift rotation and formal handovers; or you need to decide when investigation is complete enough to move to ejection and remediation. Distinct from incident response team setup (which designs the team and IR capability before incidents) — this skill executes the live response. Applies the seven-step incident command process: declare, staff, establish operational security, run forensic investigation loop, scale with rotation, apply the lead-rate decline signal to decide ejection timing, and hand off with a structured brief. Produces: incident state document, forensic timeline, communication plan, and remediation handoff package.

Adversary Profiling And Threat Modeling

Profile the likely adversaries targeting a system and produce a structured threat model with prioritized threat scenarios. Use when: designing a new system or service and need to identify who might attack it and how; evaluating whether existing security controls address the right threats; preparing a threat model document for a security review, compliance audit, or architecture decision record; assessing insider risk for a system that handles sensitive data or privileged operations; or mapping attack lifecycle stages to defensive controls. Applies the three adversary frameworks — attacker motivations, attacker profiles, and attack lifecycle stages — alongside a four-dimension actor-motive-action-target threat scenario matrix to produce ranked threat scenarios. Distinct from vulnerability assessment (which audits specific technical flaws) and penetration testing (which actively exploits weaknesses). Produces: adversary profile summary, insider risk matrix, threat scenario list ranked by likelihood and impact, and per-stage defensive control recommendations.

Disaster Risk Assessment

Use when you need to assess disaster risk for a system or organization, perform structured risk analysis before disaster planning, identify which disasters to plan for, build a prioritized risk register, quantify probability and impact of failure scenarios, or answer "what disasters should we prepare for and in what order."

Dos Defense And Mitigation

Design DoS-resistant systems or respond to an active denial-of-service attack. Use this skill when designing a new service and want to evaluate its attack surface and build in layered defenses, assessing whether a production system's architecture is DoS-hardened, investigating a traffic spike to determine whether it is an attack or a self-inflicted surge, detecting a client retry storm and needing to apply backoff and jitter fixes, building or reviewing a DoS mitigation system (detection + response pipeline), or deciding how to respond strategically to an ongoing attack without leaking information about your defenses to the adversary.

Incident Response Team Setup

Use when you need to set up an incident response team from scratch, design an IR team charter, define severity and priority models for incidents, create IR playbooks, build a structured testing program, design tabletop exercises, or answer "how do we build and validate our incident response capability."
