An AWS security assessment tool for auditing AWS accounts against CIS benchmarks, ensuring compliance requirements are met. https://github.com/prowler-cloud/prowler
Prowler is an open-source security tool designed to assess the security posture of AWS environments. It is primarily used to conduct security audits and ensure that AWS accounts follow best practices, comply with security standards, and remain resilient against potential threats. Prowler leverages AWS's IAM roles and policies to evaluate configurations of AWS resources, providing insights into areas where vulnerabilities may exist. It performs over 200 checks across various security categories, including identity and access management, network security, logging, and encryption, offering a comprehensive view of an organization's AWS security landscape.
The tool uses a command-line interface (CLI) and is designed to be easy to integrate into automated security processes. Prowler performs assessments by querying AWS services via AWS API, checking configurations against security best practices such as the CIS AWS Foundations Benchmark and the AWS Well-Architected Framework. It provides detailed reports on misconfigurations, insecure settings, and other issues that may pose a security risk to the AWS environment. With this information, users can take corrective action to improve their AWS security posture.
Prowler supports both the assessment of individual AWS accounts and multi-account environments, making it suitable for organizations of all sizes. It is compatible with multiple types of AWS accounts, including production, development, and testing environments. Additionally, the tool provides options to generate output in various formats, including JSON and HTML, to make it easier to review the results. This flexibility allows security teams to use Prowler in different workflows, from manual audits to integration with continuous integration/continuous deployment (CI/CD) pipelines.
One of the key features of Prowler is its ability to test the effectiveness of security controls across different AWS services. It checks critical configurations, such as IAM user permissions, encryption settings, S3 bucket configurations, security group rules, and CloudTrail configurations. Furthermore, Prowler is actively maintained by a community of contributors who continuously add new checks to cover emerging security concerns in AWS environments. This ensures that the tool remains up to date with the latest security trends and compliance requirements.
Conclusion
Prowler is a robust, open-source tool for auditing and improving the security posture of AWS environments. By performing a wide range of checks across security categories and providing comprehensive reports, Prowler helps organizations ensure compliance with security standards and best practices. Its integration with AWS APIs, flexible output formats, and active community support make it an essential tool for proactive security management in cloud environments.
