What is the primary purpose of the Pacu tool?

The Pacu tool is primarily designed for assessing the security configuration of Amazon Web Services (AWS) accounts. Its main functionality revolves around identifying potential security issues, misconfigurations, and vulnerabilities within AWS environments. Pacu allows users to simulate adversarial behavior to uncover weaknesses in security controls, misconfigured public access settings, and inadequate permissions across AWS services.

Understanding AWS security is critical given the shared responsibility model, where AWS maintains the infrastructure's security while users manage the security of their applications and data. Pacu helps in providing insights into these configurations and recommending remediation steps to improve overall security posture in cloud environments.

The other options pertain to different areas of security assessment, such as malware analysis, physical security, and network vulnerability scanning, which do not align with the specific capabilities and intent of the Pacu tool in relation to cloud security assessments.
