- Never trust, always verify: Require explicit authentication and authorization for every request.
- Implement mutual TLS (mTLS) between microservices to encrypt internal cluster traffic.
- Enforce Least Privilege Access (LPA) policies using fine-grained IAM roles.
Implementing Zero Trust Security in Cloud Native Applications
Traditional perimeter-based security models are obsolete in a world dominated by remote work, multi-cloud infrastructure, and microservices.
**TL;DR:** Zero Trust protects cloud applications by eliminating implicit trust, verifying identity continuously, encrypting internal communications with mTLS, and isolating workloads.
What is the core principle of Zero Trust?
The fundamental tenet is 'Never Trust, Always Verify', assuming that threats exist both outside and inside the network boundary.
