Security Change Rollout Planning

Plan and execute a security change rollout across a service or fleet: classify the change into a time horizon (short / medium / long-term), triage affected systems by risk tier, select the appropriate rollout strategy with canarying and staged deployment, define communication strategy (internal and external), set rollback and success criteria, and produce a written rollout plan. Use when you need to respond to a zero-day vulnerability, roll out a security posture improvement, or drive an ecosystem or regulatory compliance change. Handles timeline disruption scenarios: accelerate when an exploit goes public, slow down when patch instability is detected, delay when embargo, external dependency, or limited blast radius dictates caution. Produces a rollout plan with timeline, per-tier risk triage, communication strategy, and explicit rollback criteria. Examples covered: Shellshock emergency patch, hardware security key (FIDO/WebAuthn) company-wide deployment, and Chrome HTTPS migration.

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."
