Thirteen Ways Containers are More Secure than Virtual Machines
Last year, conventional wisdom had it that containers were much less secure than virtual machines (VMs)! Why? Because it was easier to break out of the container abstraction layer, which is arguably weaker than VM abstractions supported byhardware VT-x optimization. Once broken loose, malicious code could easily attack the host. Even worse, once the host is compromised, the containers lack their own operating system barriers leaving them basically undefended. Since containers have such thin separating walls; it was easy to paint these back door risks with a broad brush.
Here’s a reality check: Front door attacks and unpatched vulnerabilities are much more likely than these backdoor hacks.
