The evolution of container technology began in 1979 with Unix's chroot, laying the foundation for process isolation. FreeBSD Jails (2000) furthered this by allowing partitioned environments with individual configurations. Containers are now key to modern software deployment, offering lightweight, isolated environments to run application-specific code across various platforms (cloud, local, or data center). As container use has grown, so has the importance of security. DevSecOps integrates security directly into the container lifecycle, ensuring secure deployments through continuous assessment and enforcement of security practices in CI/CD pipelines.
