Prowler manages ensuring cloud security compliance across multiple cloud providers, including AWS, Azure, Google Cloud, and Kubernetes. This open-source tool is designed to perform comprehensive security best practices assessments, audits, incident response, continuous monitoring, hardening, and forensics readiness.
Technically, Prowler is built using Python and leverages the AWS SDK (Boto3) and Azure SDK to interact with cloud services. It can be run from various environments such as workstations, EC2 instances, Fargate, Kubernetes jobs, or even cloud-based shells like AWS CloudShell and Cloud9. The tool supports multiple output formats, including CSV, JSON, HTML, and JSON-ASFF for AWS Security Hub integration.
Prowler contains over 240 controls aligned with major security frameworks like CIS, PCI-DSS, ISO27001, GDPR, HIPAA, and others. It allows for the execution of specific checks or groups of checks, and users can also create custom security frameworks. The tool supports running checks across multiple AWS accounts in parallel or sequentially, enhancing its scalability and efficiency.
Operationally, Prowler requires proper configuration of cloud credentials, which can be managed through environment variables, AWS CLI profiles, or instance roles. The tool's flexibility extends to its deployment options, including containerization using Docker, which simplifies the process of running Prowler in various cloud and on-premises environments. However, users should be aware that the latest container tag is not stable and may introduce inconsistencies, whereas the stable tag points to the latest stable release.
In terms of technical details, Prowler's reports can be customized to include specific formats and can be sent directly to AWS Security Hub. The tool also supports advanced features like data visualizations and historical data comparisons to track security trends and improvements over time.
While Prowler offers extensive flexibility and customization, it does require careful management of dependencies such as jq and detect-secrets for optimal performance. Additionally, ensuring the latest version of AWS CLI is installed is crucial, especially when working with new regions that require STS v2 tokens.
