Amazon SQS | Security Features.

 

Amazon Simple Queue Service (SQS) provides several security features to help twtech secure message queues and the data that flows through them.

Here's twtech breakdown of key Amazon SQS security features:

 1. Authentication & Authorization

• AWS Identity and Access Management (IAM):
• twtech can use IAM policies to control who can send, receive, or delete messages in SQS.
• Fine-grained permissions allow different actions on different queues or message attributes.
• Resource-based policies: SQS supports queue access policies that define who (IAM users, roles, or AWS accounts) can access a specific queue.

 2. Encryption

• At Rest:
• SQS supports server-side encryption (SSE) using AWS Key Management Service (KMS).
• twtech can specify an AWS-managed KMS key or its own customer-managed key (CMK).
• In Transit:
• All data is encrypted using HTTPS for secure transmission over the network.

 3. Access Control

• VPC Endpoint Policies:
• twtech can use VPC endpoints (powered by AWS PrivateLink) to access SQS securely without going over the public internet.
• Policies can be attached to endpoints to restrict SQS access.
• Condition keys:
• IAM and queue policies support conditions like IP address, VPC ID, or encryption settings (aws:SourceVpce, aws:SecureTransport, etc.).

4. Audit & Monitoring

• AWS CloudTrail:
• Records all SQS API calls, helping you audit who accessed what and when.
• Amazon CloudWatch:
• Monitor queue metrics such as message age, number of messages sent/received/deleted, and more.

 5. Best Practices

• Use least privilege principle with IAM.
• Enable server-side encryption for sensitive data.
• Avoid including confidential data in message attributes unless encrypted.
• Use dead-letter queues (DLQs) to isolate and debug message-processing failures.
• Monitor activity with CloudTrail and CloudWatch for anomalies or misuse.
