🛡️ Security Analysis ResultsFound 6 security issues:
📋 Detailed Descriptions🔴 Public S3 bucket with no public access controls or encryptionFile: Description: In cdk-test/infra.ts (lines ~14-21), a new S3 bucket is created with publicReadAccess set to true, blockPublicAccess disabled, versioning off, and no server-side encryption. This exposes all objects to anonymous users and stores data unencrypted at rest. 💡 Recommendation: Remove publicReadAccess or scope it to a narrow set of principals. Enable BlockPublicAccess.BLOCK_ALL (or at minimum block public ACLs and policies), set the ACL to private, and configure server-side encryption (e.g. bucketEncryption: s3.BucketEncryption.S3_MANAGED). Enable versioning to protect against accidental deletes if appropriate. 🔴 Security Group open to all trafficFile: Description: In cdk-test/infra.ts (lines ~29-33), the security group "OpenSg" allows all inbound IPv4 traffic on all ports (0.0.0.0/0). This effectively exposes any resources in the VPC to the entire Internet. 💡 Recommendation: Restrict ingress rules to only the required ports and trusted CIDR ranges. For example, replace ec2.Peer.anyIpv4() and ec2.Port.allTraffic() with specific Port.tcp(portNumber) and your organization’s IP ranges. 🔴 Publicly accessible, unencrypted RDS instanceFile: Description: In cdk-test/infra.ts (lines ~43-50), an Amazon RDS instance is created with publiclyAccessible set to true, storageEncrypted disabled, and removalPolicy DESTROY. The database is exposed to the Internet and data at rest is unencrypted. 💡 Recommendation: Set publiclyAccessible to false unless absolutely required. Enable storageEncrypted: true and specify a KMS key if you need customer-managed encryption keys. Consider setting removalPolicy to RETAIN or enabling deletionProtection in production environments. 🟡 IAM Role granted AdministratorAccess wildcard permissionFile: Description: In cdk-test/infra.ts (lines ~36-40), the IAM role "OverPermissiveRole" is assigned the AWS-managed AdministratorAccess policy, granting broad privileges across all services and resources. 💡 Recommendation: Follow the principle of least privilege. Define a custom IAM policy or attach only the specific AWS-managed policies that grant the minimal set of actions and resources required by your workload. 🔵 Raw VPC resource instead of internal moduleFile: Description: In cdk-test/infra.ts (lines ~23-27), a VPC is created directly using ec2.Vpc. Your organization maintains an internal VPC module (git::https://github.com/diggerhq/common-modules//vpc) that enforces standard tagging, flow logging, and subnet layouts. 💡 Recommendation: Use the internal VPC module to ensure consistency: e.g., new ModuleVPC(this, 'MyVpc', { source: 'git::https://github.com/diggerhq/common-modules//vpc', /* module inputs */ }); ⚪ Destructive removal policies enabledFile: Description: In cdk-test/infra.ts (lines ~20 and ~50), both the S3 bucket and the RDS instance use removalPolicy: DESTROY. This configuration causes permanent data loss upon stack deletion. 💡 Recommendation: In non-development environments, use RemovalPolicy.RETAIN or enable snapshot/deletionProtection options to prevent accidental data loss. 📊 Summary
