Unfortunately, container security is much more difficult to achieve than security for more traditional compute platforms, such as virtual machines or bare metal hosts. Many good security tools provide that function, and benchmarks from the Center for Internet Security (CIS) are clear and prescriptive. Why is container security tricky?
