Can Attack Simulation Strengthen Real‑World Cyber Defense?

Attack simulation (often referred to as BAS) provides significant value to real‑world cyber defense, particularly when used by a purple team. By emulating attacks on endpoints, it mirrors the behavior attackers exhibit after breaching a system, allowing security teams to develop detection rules that trigger regardless of the specific technique used.

Because endpoint actions tend to follow similar patterns, BAS can cover all stages of an attack lifecycle, ensuring that even varied attack paths eventually intersect with established detection logic.

However, attack simulation is not a panacea. Simulating web zero‑day exploits remains difficult, especially after recent national vulnerability‑management regulations that restrict access to PoCs and intelligence. Without these resources, creating realistic zero‑day simulations—and the corresponding detection rules—is largely infeasible.

Consequently, while BAS is highly effective for many scenarios, its inability to replicate certain zero‑day attacks means that adversaries still rely on such exploits as a primary method for breaching defenses.
