A company wants to improve the security of its software development process and reduce the...

The correct answer is D — Containerization.

WGU Cybersecurity Architecture and Engineering (KFO1 / D488) material states that containerization provides isolated environments (containers) where applications can be developed, tested, and deployed securely. This isolation minimizes the risk of vulnerabilities affecting the host system or other applications, improving the overall security of the development process.

DLP (A) prevents data leakage but does not isolate applications. VPNs (B) secure network traffic but do not create isolated development environments. Firewalls (C) control network traffic but do not manage application-level isolation.

Reference Extract from Study Guide:

"Containerization secures application development and deployment by isolating applications in lightweight, standalone environments, reducing risk and improving manageability."
