Technical concepts to master

  • Threat modeling + STRIDE + data flow diagrams

    STRIDE · Data flow diagram (DFD) · PASTA + DREAD (alternative methodologies) · Threat modeling integration

  • Incident response + the IR lifecycle

    Preparation · Detection + analysis · Containment + eradication + recovery · Post-incident + lessons learned

  • Vulnerability management + risk prioritization

    CVSS + the limits of severity-only · Reachability + exploitability filtering · Real-risk scoring · SLA + exception management

  • Secure design + defense-in-depth + zero-trust

    Defense-in-depth · Zero-trust architecture · Principle of least privilege · Secure SDLC integration

Practical drills

  • Threat-model the firm's customer-facing REST API + admin dashboard. Walk me through your approach.
  • An alert fires: unusual outbound traffic from a customer-facing production server. Walk me through the next 60 minutes.
