Active Directory Rights Management Services is a very powerful and useful product to use for protecting sensitive and confidential data, however many people are unaware of the capabilities it has. I hope in this post to give a very high level view of what it can do and follow up with some more architectural lower level blogs for those more interested 🙂

It is recommended that an RMS install uses a SQL database on a separate machine to store all logging information, Configuration information etc. Once the RMS role is installed on a member server then a SCP (Service Connection Point) is published in AD so that whenever a user tries to protect/consume data using RMS aware applications they know where to go to get certified or licensed for this.

On the client side an RMS Client is required. Operating Systems from Vista onwards include the client in the default installation however for earlier OS’s the client can be downloaded from Microsoft. As RMS is reliant on IIS and is a web based technology the client requires an email address attribute in Active Directory as this is what RMS uses to identify users. This does NOT mean that you need exchange or any kind of email system installed internally.

When a user attempts to consume content for the first time they will receive a machine certificate as well as a Rights Account Certificate to identify them, this will check the publishing licence to see if they have access and what access they have and then send them a use licence based on this. When they first try to protect content they must be connected to the network to receive a Client Licensor Certificate which allows them to publish content, however once they have a CLC they can protect content offline. All these certificates are stored in the users profile in XrML format.

When a user tries to protect content they have two options, they can either set manual permissions, or select from templates that can be created on the Root Cluster. As well as permissions you set conditions, some of these include allowing the ability to print, forward or when you want the content to expire and therefore be inaccessible (Microsoft is currently working towards automatic protection and this is implemented to a degree in SharePoint 2007 and very well in Exchange 2010, will hopefully go into more detail in a later post!)

Currently RMS aware file formats include the Office suite (excluding One Note) and xps although additional IRM protectors can be downloaded from 3rd party sites to support protection for hundreds of file formats, very cool stuff! 🙂

See my next post for more information on the RMS Certificates.
