Cloud Security CTF: AWS Topics and Learning Areas
This Cloud Security CTF focuses on practical AWS security concepts such as IAM permissions, S3 misconfigurations, EC2 and metadata services, VPC and security groups, Lambda, API Gateway, secrets exposure, CloudTrail logs, and cloud privilege escalation. Participants will explore common AWS security weaknesses and apply real-world cloud security techniques to identify and exploit misconfigurations.
A Cloud Security CTF can be designed around common AWS security concepts and real-world cloud misconfigurations. The goal is to help participants understand how cloud resources are configured, how permissions work, and how security weaknesses can lead to unauthorized access.
The CTF can cover AWS IAM, including users, roles, policies, permission boundaries, and privilege escalation. Participants can learn how overly permissive policies such as
AdministratorAccess or wildcard permissions can create security risks.Amazon S3 can cover publicly accessible buckets, incorrect bucket policies, exposed objects, and insecure access controls. Challenges can require participants to identify sensitive information stored in improperly secured buckets.
EC2 and Metadata Services can introduce instance roles, security groups, exposed services, and the risks associated with the Instance Metadata Service (IMDS). Participants can explore how cloud credentials may be exposed through insecure configurations.
Other useful areas include AWS Lambda, API Gateway, CloudWatch, Secrets Manager, and VPC networking. These can introduce concepts such as exposed APIs, leaked secrets, logging, network segmentation, and security group misconfigurations.
The CTF can also include CloudTrail and cloud log analysis, where participants investigate suspicious activity and identify actions performed by compromised accounts or roles.
Advanced challenges can cover IAM privilege escalation, SSRF-to-cloud-credential scenarios, cross-account access, container security, ECR, ECS, and Kubernetes/EKS security.
Overall, an AWS-focused CTF can combine identity security, storage security, network security, application security, monitoring, and incident response to provide practical cloud-security experience.
