Summary

Security is definitely a challenge and an important aspect not to be sidestepped. If a container gets compromised, then bringing down the container host is not a difficult task. Thus, ensuring security for containers and then hosts is indispensable to the flourishing of the containerization concept, especially when the centralization and federation of IT systems is on the rise. In this chapter, we specifically focused on the sickening and devastating security issues of Docker containers and explained the ways and means of having foolproof security solutions for containers that host dynamic, enterprise-class, and mission-critical applications. In the days to come, there will be fresh security approaches and solutions in order to ensure impenetrable and unbreakable security for Docker containers and hosts, as the security of containers and their contents is of utmost importance to service providers, as well as consumers.
