Breach and Attack Simulation Guide

Breach and Attack Simulation (BAS) goes beyond traditional penetration testing by continuously and automatically simulating real-world attack scenarios. This guide helps security teams understand, plan, and execute BAS programs to validate security controls.

Unlike point-in-time penetration tests, BAS runs continuously — giving security teams ongoing visibility into which controls are working, which have drifted, and where attackers could succeed today. This guide is designed for security managers, CISOs, and red team leads looking to establish or mature their continuous validation programs. Whether you're evaluating BAS platforms or building an in-house simulation capability, this resource provides the frameworks, templates, and MITRE ATT&CK mappings you need to demonstrate security control effectiveness to your board.

• Setting up your BAS program objectives and scope
• Attack scenario library: phishing, lateral movement, data exfiltration
• Mapping BAS results to MITRE ATT&CK framework
• Reporting and prioritizing remediation
• Continuous validation program management
