Security Testing

Breach and Attack Simulation (BAS)

Breach and Attack Simulation is an advanced security testing approach that uses automation to continuously simulate real-world attack techniques against an organization's infrastructure, providing ongoing validation of security controls.

What Is BAS?

BAS platforms automate the process of launching simulated attacks across multiple vectors — including network, endpoint, email, and web — to test whether existing security tools and processes detect and block them. Unlike point-in-time assessments, BAS runs continuously, providing up-to-date security posture visibility.

How BAS Works

  1. Attack Scenario Library: Pre-built playbooks modeled after known threat actor techniques
  2. Automated Execution: Simulated attacks run automatically against production or staging environments
  3. Detection Analysis: Results show which attacks were detected, blocked, or missed
  4. Remediation Guidance: Actionable recommendations to close identified gaps

Use Cases

  • Validating SIEM detection rules and alerting
  • Testing EDR effectiveness after deployment
  • Compliance verification and audit preparation
  • Security control benchmarking after infrastructure changes
