All around you, whether you know it or not, are containerized applications. They provide Wifi in your local cafe, process your purchase at the grocery store, and serve up your online banking. You might send your doctor a message through a mobile app and then play your favorite mobile game, all running in containers.

With real workloads come real consequences. Your business is your data, and running your business-critical data in containers has elevated this once-buzzword to something business leaders are forced to make decisions about. If you’re evaluating a cloud provider and your security lead says, “Cloud A offers managed images; for Cloud B, we’d be on our own,” how important is that? Should it influence your decision?

The goal of this book is to teach you the fundamentals of container security so when it comes time to make business decisions, you’ll have the context you need to help keep your business safe.
