Security best practices for deployment
As we presented in Chapter 5, Managing Security, Data, and Compliance on Multi-Cloud, security is paramount when deploying cloud-native applications in multi-cloud environments. In this section, we’ll explore key security measures such as encryption and IAM and security audits, to safeguard your applications:
- Encryption: This is fundamental for securing data both in transit and at rest. It ensures that even if unauthorized access occurs, the data remains unreadable. Let’s consider some examples:
- Transport Layer Security (TLS)/Secure Sockets Layer (SSL): Implement TLS/SSL for data in transit. For instance, you can configure NGINX as a reverse proxy with Let’s Encrypt to automatically manage SSL certificates, securing communication between users and your application.
- Encryption-at-rest: Employ encryption mechanisms provided by cloud providers. In AWS, use Amazon S3 server-side encryption to protect data stored in S3 buckets...
