Summary

PDF p.306

Testing and training validate the preparation process and ensure the organization is ready for incident response. They help develop competencies, identify deficiencies, and improve team resilience.

In plain words

Supplementary — not from your PDF

Test IR readiness with tabletop exercises (cheapest; responders talk through a scenario), walkthroughs (responders demonstrate actions with sandboxed tools), and simulations (red team attackers, blue team defenders, white team referees; the most costly). Training covers detecting and reporting incidents, cross-department coordination, awareness and compliance, and team communication.

Detailed explanation

Testing

  • Purpose: Helps staff develop competencies and identify deficiencies in procedures and tools.
  • Forms of Testing
    • Tabletop Exercise
      • Description: Least costly. Facilitator presents a scenario, and responders explain their actions using flash cards.
    • Walkthroughs
      • Description: Facilitator presents a scenario, and responders demonstrate actions using sandboxed tools.
    • Simulations
      • Description: Team-based exercise with red team (attackers), blue team (responders), and white team (moderators). Requires significant investment and planning.

Training

  • Purpose: Equips staff with knowledge to react swiftly and effectively to security events.
  • Focus Areas
    • Incident Detection and Reporting: Ensures staff can recognize and report incidents.
    • Cross-Departmental Training: Coordinates efforts across different departments.
    • Security Awareness and Compliance: Helps employees identify future attacks.
    • Team Building and Communication: Improves resilience and working relationships during stressful incidents.

  • A quarterly phishing tabletop with IT and HR.
  • A walkthrough using a lab environment.
  • A red/blue/white team exercise on a test network.

Scenario

A company wants a realistic test of its SOC's detection without risking production. A simulation in an isolated lab, with a red team, blue team and white team, gives realistic practice safely.

Common mistakes

Supplementary — not from your PDF
  • Mixing up the team colours: red attacks, blue defends, white moderates.
  • Only ever doing tabletops and never practising with tools.
