The "Defensive" Skill That Raises Market Value: Best Practices for Cloud-Native Security Implementation

In the modern era where Digital Transformation (DX) is accelerating, the mainstream of system development is shifting to "Cloud-Native." While rapid development utilizing containers and microservices is possible, traditional security measures (perimeter defense premised on on-premises) are no longer sufficient to protect complex systems.

There is now a strong demand for infrastructure engineers and developers to have "Cloud-Native Security" skills, implementing security throughout the entire development lifecycle.

What is Cloud-Native Security?

This is an approach to protect applications built with cloud-native technologies (containers, microservices, serverless, etc.) tailored to their specific characteristics.

Whereas the conventional model was based on the idea of protecting with a "castle wall (perimeter)," cloud-native requires the continuous protection of the entire "dynamic environment." The core concepts are "Shift Left," which involves building security in from the early stages of development, and "DevSecOps," where development, operations, and security collaborate.

Implementation Best Practices Valued in the Job Market

What specific practices are required? Here are the main best practices that increase market value.

1. Security Integration into the CI/CD Pipeline

Automate security checks at each stage of the development process (CI/CD). Build a system to discover and fix vulnerabilities early by incorporating static analysis (SAST) at code commit, container image scanning, and dynamic analysis (DAST) before deployment.

2. Adoption of Zero Trust Architecture (ZTA)

Based on the principle of "Trust Nothing, Verify Everything," all access requests are verified, even within the internal network. Minimize the risk of unauthorized access by enforcing strong authentication (such as multi-factor authentication) and the principle of least privilege.

3. Thorough Container Security

Vulnerability scanning of container images, use of trusted base images, and monitoring of suspicious behavior at runtime are essential. Close attention is also required for misconfigurations in orchestration tools like Kubernetes.

4. IaC (Infrastructure as Code) Security

When managing infrastructure as code with tools like Terraform, risks (e.g., opening unnecessary ports) can lurk within the configuration files themselves. Maintain a secure configuration by introducing tools that scan IaC settings.

Why is the Market Value of "Engineers Who Can Defend" So High?

An engineer who can implement cloud-native security is not just someone who can "develop," but someone who can "continuously deliver secure services rapidly."

A security incident can fundamentally shake corporate trust. Therefore, engineers with DevSecOps knowledge who can balance development speed with security are in extremely high demand, regardless of industry or company size, leading directly to career advancement and favorable job offers.

Conclusion

With the spread of cloud-native, the importance of security is only increasing. Engineers who understand "infrastructure, development, and security" are the ones who will lead the IT industry going forward.
