This section discusses the security features you can configure and use within your Docker Engine installation.
You can configure Docker's trust features so that your users can push and pull trusted images. To learn how to do this, see Use trusted images in this section.
You can protect the Docker daemon socket and ensure only trusted Docker client connections. For more information, Protect the Docker daemon socket
You can use certificate-based client-server authentication to verify a Docker daemon has the rights to access images on a registry. For more information, see Using certificates for repository client verification.
You can configure secure computing mode (Seccomp) policies to secure system calls in a container. For more information, see Seccomp security profiles for Docker.
An AppArmor profile for Docker is installed with the official .deb packages. For information about this profile and overriding it, see AppArmor security profiles for Docker.
