AWS Cloud Security & Hardening Checklist
What's Inside?
Securing Amazon Web Services (AWS) infrastructure requires a shared responsibility model. This checklist provides a structured guide to auditing your AWS environment, managing identities, securing network configurations, and monitoring logs.
Key AWS Hardening Focus Areas:
Identity & Access Management: Enforce MFA for all IAM users and restrict AWS root user usage.
Least Privilege: Utilize IAM Roles instead of long-term credentials for EC2 and ECS resources.
S3 Bucket Security: Block public access by default and enable server-side encryption.
VPC Network Isolation: Restrict Security Group access and use private subnets for backend resources.
AWS CloudTrail: Enable multi-region trail logging and store logs in an encrypted S3 bucket.
KMS Key Management: Use customer-managed keys (CMK) with automated rotation enabled.
VPC Flow Logs: Enable network traffic logging to detect anomalous inter-subnet activity.
AWS GuardDuty: Activate intelligent threat detection to analyze logs and alert on threats.
Secrets Manager: Securely store database credentials and rotate them dynamically.
IAM Credential Report: Regularly audit inactive users, unused access keys, and passwords.
AWS Config: Deploy configuration rules to continuously monitor resource compliance.
Patch Management: Set up AWS Systems Manager (SSM) Patch Manager for automated server patching.
