Kubernetes and cloud applications let complex systems run reliably in unreliable environments. In doing so, however, they can expose an organization to a multitude of security issues. While some organizations do a great job of securing their infrastructure, many fall into one of two categories:

• Those who are unaware that their clusters are insecure.
• Those who know their clusters are insecure, but have no idea where to start securing them.

Fortunately, organizations can easily mitigate most Kubernetes security issues by taking action in four main areas:

• Secure the cluster
• Control access
• Provide a secure software development process
• Build a secure DevOps culture
