+
+Docker Security
+===============
+
+  *Adapted from* `Containers & Docker: How Secure are They? <blogsecurity>`_
+
+There are three major areas to consider when reviewing Docker security:
+
+* the intrinsic security of containers, as implemented by kernel
+  namespaces and cgroups;
+* the attack surface of the Docker daemon itself;
+* the "hardening" security features of the kernel and how they
+  interact with containers.
+
+Kernel Namespaces
+-----------------
+
+Docker containers are essentially LXC containers, and they come with
+the same security features. When you start a container with ``docker
+run``, behind the scenes Docker uses ``lxc-start`` to execute the
+Docker container. This creates a set of namespaces and control groups
+for the container. Those namespaces and control groups are not created
+by Docker itself, but by ``lxc-start``. This means that as the LXC
+userland tools evolve (and provide additional namespaces and isolation
+features), Docker will automatically make use of them.
+
+**Namespaces provide the first and most straightforward form of
+isolation**: processes running within a container cannot see, and even
+less affect, processes running in another container, or in the host
+system.
+
+**Each container also gets its own network stack**, meaning that a
+container doesn’t get a privileged access to the sockets or interfaces
+of another container. Of course, if the host system is setup
+accordingly, containers can interact with each other through their
+respective network interfaces — just like they can interact with
+external hosts. When you specify public ports for your containers or
+use :ref:`links <working_with_links_names>` then IP traffic is allowed
+between containers. They can ping each other, send/receive UDP
+packets, and establish TCP connections, but that can be restricted if
+necessary. From a network architecture point of view, all containers
+on a given Docker host are sitting on bridge interfaces. This means
+that they are just like physical machines connected through a common
+Ethernet switch; no more, no less.
+
+How mature is the code providing kernel namespaces and private
+networking?  Kernel namespaces were introduced `between kernel version
+2.6.15 and 2.6.26
+<http://lxc.sourceforge.net/index.php/about/kernel-namespaces/>`_. This
+means that since July 2008 (date of the 2.6.26 release, now 5 years
+ago), namespace code has been exercised and scrutinized on a large
+number of production systems. And there is more: the design and
+inspiration for the namespaces code are even older. Namespaces are
+actually an effort to reimplement the features of `OpenVZ
+<http://en.wikipedia.org/wiki/OpenVZ>`_ in such a way that they could
+be merged within the mainstream kernel. And OpenVZ was initially
+released in 2005, so both the design and the implementation are
+pretty mature.
+
+Control Groups
+--------------
+
+Control Groups are the other key component of Linux Containers. They
+implement resource accounting and limiting. They provide a lot of very
+useful metrics, but they also help to ensure that each container gets
+its fair share of memory, CPU, disk I/O; and, more importantly, that a
+single container cannot bring the system down by exhausting one of
+those resources.
+
+So while they do not play a role in preventing one container from
+accessing or affecting the data and processes of another container,
+they are essential to fend off some denial-of-service attacks. They
+are particularly important on multi-tenant platforms, like public and
+private PaaS, to guarantee a consistent uptime (and performance) even
+when some applications start to misbehave.
+
+Control Groups have been around for a while as well: the code was
+started in 2006, and initially merged in kernel 2.6.24.
+
+Docker Daemon Attack Surface
+----------------------------
+
+Running containers (and applications) with Docker implies running the
+Docker daemon. This daemon currently requires root privileges, and you
+should therefore be aware of some important details.
+
+First of all, **only trusted users should be allowed to control your
+Docker daemon**. This is a direct consequence of some powerful Docker
+features. Specifically, Docker allows you to share a directory between
+the Docker host and a guest container; and it allows you to do so
+without limiting the access rights of the container. This means that
+you can start a container where the ``/host`` directory will be the
+``/`` directory on your host; and the container will be able to alter
+your host filesystem without any restriction. This sounds crazy? Well,
+you have to know that **all virtualization systems allowing filesystem
+resource sharing behave the same way**. Nothing prevents you from
+sharing your root filesystem (or even your root block device) with a
+virtual machine.
+
+This has a strong security implication: if you instrument Docker from
+e.g. a web server to provision containers through an API, you should
+be even more careful than usual with parameter checking, to make sure
+that a malicious user cannot pass crafted parameters causing Docker to
+create arbitrary containers.
+
+For this reason, the REST API endpoint (used by the Docker CLI to
+communicate with the Docker daemon) changed in Docker 0.5.2, and now
+uses a UNIX socket instead of a TCP socket bound on 127.0.0.1 (the
+latter being prone to cross-site-scripting attacks if you happen to
+run Docker directly on your local machine, outside of a VM). You can
+then use traditional UNIX permission checks to limit access to the
+control socket.
+
+You can also expose the REST API over HTTP if you explicitly decide
+so. However, if you do that, being aware of the abovementioned
+security implication, you should ensure that it will be reachable
+only from a trusted network or VPN; or protected with e.g. ``stunnel``
+and client SSL certificates.
+
+Recent improvements in Linux namespaces will soon allow to run
+full-featured containers without root privileges, thanks to the new
+user namespace. This is covered in detail `here
+<http://s3hh.wordpress.com/2013/07/19/creating-and-using-containers-without-privilege/>`_. Moreover,
+this will solve the problem caused by sharing filesystems between host
+and guest, since the user namespace allows users within containers
+(including the root user) to be mapped to other users in the host
+system.
+
+The end goal for Docker is therefore to implement two additional
+security improvements:
+
+* map the root user of a container to a non-root user of the Docker
+  host, to mitigate the effects of a container-to-host privilege
+  escalation;
+* allow the Docker daemon to run without root privileges, and delegate
+  operations requiring those privileges to well-audited sub-processes,
+  each with its own (very limited) scope: virtual network setup,
+  filesystem management, etc.
+
+Finally, if you run Docker on a server, it is recommended to run
+exclusively Docker in the server, and move all other services within
+containers controlled by Docker. Of course, it is fine to keep your
+favorite admin tools (probably at least an SSH server), as well as
+existing monitoring/supervision processes (e.g. NRPE, collectd, etc).
+
+Linux Kernel Capabilities
+-------------------------
+
+By default, Docker starts containers with a very restricted set of
+capabilities. What does that mean?
+
+Capabilities turn the binary "root/non-root" dichotomy into a
+fine-grained access control system. Processes (like web servers) that
+just need to bind on a port below 1024 do not have to run as root:
+they can just be granted the ``net_bind_service`` capability
+instead. And there are many other capabilities, for almost all the
+specific areas where root privileges are usually needed.
+
+This means a lot for container security; let’s see why!
+
+Your average server (bare metal or virtual machine) needs to run a
+bunch of processes as root. Those typically include SSH, cron,
+syslogd; hardware management tools (to e.g. load modules), network
+configuration tools (to handle e.g. DHCP, WPA, or VPNs), and much
+more. A container is very different, because almost all of those tasks
+are handled by the infrastructure around the container:
+
+* SSH access will typically be managed by a single server running in
+  the Docker host;
+* ``cron``, when necessary, should run as a user process, dedicated
+  and tailored for the app that needs its scheduling service, rather
+  than as a platform-wide facility;
+* log management will also typically be handed to Docker, or by
+  third-party services like Loggly or Splunk;
+* hardware management is irrelevant, meaning that you never need to
+  run ``udevd`` or equivalent daemons within containers;
+* network management happens outside of the containers, enforcing
+  separation of concerns as much as possible, meaning that a container
+  should never need to perform ``ifconfig``, ``route``, or ip commands
+  (except when a container is specifically engineered to behave like a
+  router or firewall, of course).
+
+This means that in most cases, containers will not need "real" root
+privileges *at all*. And therefore, containers can run with a reduced
+capability set; meaning that "root" within a container has much less
+privileges than the real "root". For instance, it is possible to:
+
+* deny all "mount" operations;
+* deny access to raw sockets (to prevent packet spoofing);
+* deny access to some filesystem operations, like creating new device
+  nodes, changing the owner of files, or altering attributes
+  (including the immutable flag);
+* deny module loading;
+* and many others.
+
+This means that even if an intruder manages to escalate to root within
+a container, it will be much harder to do serious damage, or to
+escalate to the host.
+
+This won't affect regular web apps; but malicious users will find that
+the arsenal at their disposal has shrunk considerably! You can see
+`the list of dropped capabilities in the Docker code
+<https://github.com/dotcloud/docker/blob/v0.5.0/lxc_template.go#L97>`_,
+and a full list of available capabilities in `Linux manpages
+<http://man7.org/linux/man-pages/man7/capabilities.7.html>`_.
+
+Of course, you can always enable extra capabilities if you really need
+them (for instance, if you want to use a FUSE-based filesystem), but
+by default, Docker containers will be locked down to ensure maximum
+safety.
+
+Other Kernel Security Features
+------------------------------
+
+Capabilities are just one of the many security features provided by
+modern Linux kernels. It is also possible to leverage existing,
+well-known systems like TOMOYO, AppArmor, SELinux, GRSEC, etc. with
+Docker.
+
+While Docker currently only enables capabilities, it doesn't interfere
+with the other systems. This means that there are many different ways
+to harden a Docker host. Here are a few examples.
+
+* You can run a kernel with GRSEC and PAX. This will add many safety
+  checks, both at compile-time and run-time; it will also defeat many
+  exploits, thanks to techniques like address randomization. It
+  doesn’t require Docker-specific configuration, since those security
+  features apply system-wide, independently of containers.
+* If your distribution comes with security model templates for LXC
+  containers, you can use them out of the box. For instance, Ubuntu
+  comes with AppArmor templates for LXC, and those templates provide
+  an extra safety net (even though it overlaps greatly with
+  capabilities).
+* You can define your own policies using your favorite access control
+  mechanism. Since Docker containers are standard LXC containers,
+  there is nothing “magic” or specific to Docker.
+
+Just like there are many third-party tools to augment Docker
+containers with e.g. special network topologies or shared filesystems,
+you can expect to see tools to harden existing Docker containers
+without affecting Docker’s core.
+
+Conclusions
+-----------
+
+Docker containers are, by default, quite secure; especially if you
+take care of running your processes inside the containers as
+non-privileged users (i.e. non root).
+
+You can add an extra layer of safety by enabling Apparmor, SELinux,
+GRSEC, or your favorite hardening solution.
+
+Last but not least, if you see interesting security features in other
+containerization systems, you will be able to implement them as well
+with Docker, since everything is provided by the kernel anyway.
+
+For more context and especially for comparisons with VMs and other
+container systems, please also see the `original blog post
