AWS Security Configuration Review and Best Practices

This HackerOne whitepaper describes a methodology-driven AWS security configuration review (PTaaS) aligned with CIS benchmarks and the AWS Well-Architected Framework, outlines common AWS misconfigurations (IAM, SCPs, security groups/NACLs, S3, CloudTrail) and associated risks, and uses the 2019 Capital One breach as a case study to illustrate the impact of misconfigurations; it promotes continuous, community-driven testing, skilled AWS-certified researchers, and integration with AWS Security Hub for vulnerability management.
