How do Pub/Sub and SQS compare in terms of security?

How do Pub/Sub and SQS compare in terms of security?

Both Pub/Sub and SQS offer robust security features, but they differ in implementation. Pub/Sub uses IAM roles and policies for access control, while SQS relies on AWS IAM for permissions. Additionally, Pub/Sub encrypts data in transit and at rest by default, whereas SQS requires you to enable server-side encryption.

What are the specific encryption methods used by each?

Pub/Sub uses Google-managed encryption keys for data at rest and TLS for data in transit. SQS can use AWS KMS for server-side encryption and also employs TLS for data in transit.

Are there any compliance certifications for both services?

Yes, both services comply with various standards. Pub/Sub is compliant with ISO 27001, GDPR, and HIPAA, while SQS meets compliance for ISO 27001, PCI DSS, and HIPAA as well.

Which one is better for sensitive data?

It depends on your specific requirements and existing infrastructure. If you're already using Google Cloud, Pub/Sub might be more seamless. For AWS environments, SQS could be more integrated. Both can handle sensitive data securely.
