As a seasoned AWS pentester, I’ve spent years navigating the intricate world of AWS security, exploring everything from access management to service-specific vulnerabilities.
Exploring AWS Security
Throughout my career, I’ve delved deeply into AWS’s vast array of services, identifying both security strengths and potential weaknesses. Here are some of the key topics I cover:
- IAM Policy Permissions: AWS Identity and Access Management (IAM) forms the backbone of access control in the cloud. My experience ranges from analyzing overly permissive roles to crafting fine-grained policies that ensure least-privilege access. I’ve worked on findings related to misconfigured policies, such as overly broad assumeRole permissions and policies allowing full admin access.
- Service-Specific Vulnerabilities: Each AWS service introduces its own set of security challenges. Whether it’s S3 bucket misconfigurations, Lambda execution role vulnerabilities, or ECS task policies, I explore the nuances of each service from a security perspective. Through pentesting, I’ve uncovered flaws like unencrypted CloudTrail logs and improper ACLs that allow unrestricted access.
- Networking & Cloud Architecture: Understanding the complex networking in AWS is critical. From VPC peering to security groups and NACLs, I test environments to identify weak spots that can be exploited. My work includes findings related to exposed ports, improper firewall configurations, and the dangers of unrestricted ingress and egress traffic.
- Encryption & Key Management: Proper encryption is key to cloud security. I’ve examined systems that fail to use AWS KMS (Key Management Service) or use outdated algorithms like SHA-1, creating vulnerabilities in otherwise secure environments.
- Serverless & Microservices Security: As serverless architectures grow, so do their security implications. I’ve tested Lambda functions, API Gateway configurations, and ECS workloads to ensure they are secure from injection attacks, misconfigurations, and privilege escalations.
