Securing Docker Containers: Unraveling the Challenges and Solutions

The adoption of virtualization technology has grown significantly during the past few years. The two primary types of virtualization technologies that have entered the market are container-based virtualization and hypervisor-based virtualization. The investigation looks at two topics: (1) Docker's internal security, and (2) how Docker works with the Linux kernel's security features like SELinux and AppArmor to strengthen the host system. Over the past few years, Linux containers have gained prominence, integrating into commercial IT service offerings such as PaaS, application deployments, and continuous delivery pipelines for delivery and integration among various development teams. In this work, we aim to demonstrate the security of Cloud PaaS by understanding it in terms of Docker container security. We build upon our earlier research on the security of Docker containers in this article and examine a way to enhance container security utilizing multilateral balanced security. We made an effort to comprehend the security issues, incidents, narratives, mishaps, and experiences they had while creating, implementing, and applying the cloud resources/services remotely through the internet.
