DTR can be installed on-premises, or on a virtual private
cloud. And with it, you can store your Docker images securely, behind your
firewall.

You can use DTR as part of your continuous integration, and continuous
delivery processes to build, run, and ship your applications.
delivery processes to build, ship and run your applications.
DTR has a web based user interface that allows authorized users in your
organization to browse docker images. It provides information about
who pushed what image at what time. It even allows you to see what dockerfile
lines were used to produce the image and, if security scanning is enabled, to
see a list of all of the software installed in your images.
## Built-in security and access control
## Built-in access control
DTR uses the same authentication mechanism as Docker Universal Control Plane.
It has a built-in authentication mechanism, and also integrates with LDAP
and Active Directory. It also supports Role Based Access Control (RBAC).
Users can be managed manually or syched from LDAP or Active Directory. DTR
uses [Role Based Access Control](admin/manage-users/index.md) (RBAC) to allow you to implement fine-grained
access control policies for who has access to your Docker images.
This allows you to implement fine-grain access control policies on who has
access to your Docker images.
## Security scanning
![](images/overview-2.png)
DTR has a built in security scanner that can be used to discover what versions
of software are used in your images. It scans each layer and aggregates the
results to give you a complete picture of what you are shipping as a part of
your stack. Most importantly, it co-relates this information with a
vulnerability database that is kept up to date through [periodic
updates](admin/configure/set-up-vulnerability-scans.md). This
gives you [unprecedented insight into your exposure to known security
threats](user/manage-images/scan-images-for-vulnerabilities.md).
## Image signing
DTR ships with [Notary](../../../notary/getting_started/)
built in so that you can use
[Docker Content Trust](../../../engine/security/trust/content_trust/) to sign
and verify images. For more information about managing Notary data in DTR see
the [DTR-specific notary documentation](user/manage-images/manage-trusted-repositories.md).
