Elevating Defense-in-Depth with Breach and Attack Simulation (BAS)

The Defense-in-Depth strategy, inspired by medieval castle designs, remains a cornerstone in modern cybersecurity, employing multiple layers of security controls.

However, the prevalence of security breaches suggests a false sense of security, emphasizing the need for continuous improvement and testing. Traditional defense layers include Network, Host, Application, and Data Layers, each fortified with specific security controls.

To enhance Defense-in-Depth, organizations are turning to Breach and Attack Simulation (BAS), an automated tool that rigorously assesses security controls across layers. BAS operates in conjunction with threat intelligence, leveraging automation, and deep learning models like ChatGPT, Bard, and LLaMA for comprehensive cyber threat analysis.

BAS simulates real cyber threats at each layer, starting with testing the network layer’s ability to identify and block malicious traffic. It assesses the host layer by probing individual devices for vulnerabilities and susceptibility to malware. The application layer is scrutinized for exposure through public-facing applications, mimicking adversary actions to validate security controls. In the data layer, where ransomware and data exfiltration threats loom, BAS evaluates the efficacy of security controls like Data Loss Prevention (DLP) and access controls.


The continuous validation provided by BAS ensures that an organization’s Defense-in-Depth strategy evolves with the dynamic threat landscape. By proactively identifying and mitigating security gaps, BAS empowers security teams to trust their controls against sophisticated cyber attacks.
