As organizations accelerate their digital transformation, container technologies have emerged as a cornerstone for application deployment, emphasizing the need for robust security measures. Traditional security model that is perimeter-based are not sufficient to address the dynamic and dispersed nature of container environments. This paper introduces a Zero Trust Container Framework (ZTCF), rooted in the “never trust, always verify” principle, to enhance container ecosystem security. The framework integrates identity verification, continuous monitoring, and automated threat response to address specific vulnerabilities and requirements throughout the container lifecycle. Experimental analysis comparing legacy systems with the proposed framework demonstrates significant improvements in security posture, compliance, and resilience. This research offers actionable insights for designing secure, scalable, and resilient containerized systems, guiding organizations in strengthening their security strategies as they adapt to the evolving digital landscape.
