Overview: Cloud Native Security

Quick Definition

A Cloud Native Security approach is a cybersecurity strategy designed specifically for applications and infrastructure built for cloud environments. This methodology emphasizes security practices that are integrated throughout the entire development lifecycle, from code creation to deployment and runtime operations, rather than being added as an afterthought.

Cloud native security operates on the principle of "shift-left" security, meaning security considerations are incorporated early in the development process. It leverages containerization, microservices architectures, and DevSecOps practices to create more resilient and secure applications. Key components include container security, API protection, identity and access management, and automated security testing integrated into CI/CD pipelines.

This approach differs from traditional security models by embracing the dynamic, distributed nature of cloud environments. It relies heavily on automation, policy-as-code, and continuous monitoring to address the rapid scaling and ephemeral nature of cloud native applications. Security tools and processes must be designed to work seamlessly with orchestration platforms like Kubernetes while maintaining visibility across multiple cloud services and environments.

The methodology also emphasizes zero-trust principles, assuming no inherent trust between services and requiring verification for every transaction or interaction within the system.
