So you have your Docker Containers deployed, which in turn are hosting critical applications of your organization? Great! So far, so good!
For the interest of the organization, it remains extremely crucial to keep not only the Containers but also the hosted applications protected from security threats. By default, a deployed Docker originally remains secured through an auto-generated profile docker-default for its containers. This profile, however, provides moderate security on the application level, and thus it remains highly recommended to implement a security profile through AppArmor which works at the process/program level of an application.
