Securing Cloud Applications

In a cloud-native world, security cannot be an afterthought. The traditional "perimeter" defense is no longer sufficient. We must adopt a Zero Trust architecture.

1. Identity and Access Management (IAM)

Implementing modern authentication is step one. OAuth 2.0 and OpenID Connect (OIDC) are the industry standards.

• Use JWTs (JSON Web Tokens) for stateless authentication between microservices.
• Implement Role-Based Access Control (RBAC) to restrict permissions.

2. Securing Data in Transit and at Rest

Encryption is non-negotiable.

• TLS 1.2+ for all network traffic.
• Encrypt sensitive data (like PI, passwords, secrets) in your database.

3. Secrets Management

Never hardcode credentials in your source code. Use tools like HashiCorp Vault, AWS Secrets Manager, or Spring Cloud Config Server to manage API keys and database passwords securely.

4. Dependency Scanning

Your code is only as secure as the libraries you use. Automated tools like OWASP Dependency-Check or Snyk can scan your build pipeline for vulnerabilities.

Conclusion

Security is a shared responsibility. By integrating security practices into your CI/CD pipeline (DevSecOps), you can ensure your cloud applications remain robust against threats.
