Container security is a fairly new technology, especially when viewed in the context of the speed of light technology changes in the fourth industrial revolution (4IR). Container technology itself is a topic that many security practitioners continue to find confusing, but its use is spreading fast, writes Craig De Lucchi, account director of CA Southern Africa.

Let’s unpack what does containerisation mean? While definitions differ, but only slightly in the wording, all come down to the same conclusion and that is that containerisation is a form of operating system (OS) virtualisation where applications that use a shared OS run in isolated user spaces, called containers.

Software containers are lightweight, standalone, executable packages of software that include everything required to run them. Containers include code, runtime, settings, system libraries and tools and can be used with both Linux and Windows-based applications.
