BAS: Breach and Attack Simulation in Cybersecurity
Rhymes with 'gas'. Sometimes spelled out.
BAS stands for Breach and Attack Simulation. BAS platforms automatically simulate real-world attack techniques against an organization's production environment to test whether security controls detect and prevent them. BAS runs continuously, providing ongoing validation rather than point-in-time testing.
How BAS Is Used in Cybersecurity
Security engineers run BAS scenarios to verify that SIEM rules, EDR policies, and firewall configurations actually block known attack chains. Penetration testers use BAS results to identify control gaps before manual testing begins. CISOs use BAS reports to measure defensive coverage against MITRE ATT&CK techniques and track improvement over time.
