Offensive C# — Lesson 3: Detection, Analysis, and Adversary Simulation

Learning Objectives

• Map controlled behaviors to telemetry, event logs, endpoint alerts, and network evidence
• Analyze code and runtime activity for suspicious indicators and weaknesses
• Use adversary-simulation results to validate security controls without targeting real systems

Detailed Topics

• Map controlled behaviors to telemetry: Map controlled behaviors to telemetry, event logs, endpoint alerts, and network evidence
• Analyze code and runtime activity for suspicious indicators and weaknesses: Analyze code and runtime activity for suspicious indicators and weaknesses
• Use adversary-simulation results to validate security controls without targeting real systems: Use adversary-simulation results to validate security controls without targeting real systems

Guided Demonstration

1. Review the requirement, users, data, dependencies, permissions, risks, and expected result.
2. Demonstrate the relevant configuration, development, administration, analysis, or collaboration workflow step by step.
3. Capture settings, outputs, logs, screenshots, calculations, test results, and other useful evidence.
4. Compare the observed result with acceptance criteria and explain any corrective action.

Hands-On Activity

Run an authorized simulation and correlate activity with defensive telemetry.

• Document assumptions, prerequisites, and the planned sequence before starting.
• Complete the activity and preserve evidence of normal, boundary, and failure behavior.
• Record issues, corrective actions, reusable notes, and the next improvement priority.

Scenario Analysis

• Identify the business or technical decision that must be made.
• Compare valid implementation approaches and their trade-offs.
• Consider security, privacy, accessibility, performance, support, and operational impact.

Troubleshooting Focus

• Separate symptoms from causes and collect evidence before applying a fix.
• Check configuration, data, permissions, dependencies, capacity, connectivity, and recent changes.
• Validate rollback, recovery, ownership, user impact, and business continuity.

Validation Checklist

• The requirement, scope, inputs, and expected outcome are clear.
• The selected design or configuration is documented and follows approved standards.
• Normal, boundary, failure, security, accessibility, and operational conditions are reviewed.
• The result is supported by evidence and the next improvement is prioritized.

Lesson Outcome

Learners can explain and apply Detection, Analysis, and Adversary Simulation in a realistic scenario and validate the result with documented evidence.
