Hello and welcome to Information Rights Management. In this lesson, we'll take a quick look at what it is and what it's used for. Information Rights Management, or IRM, is used by organizations to prevent unauthorized recipients of protected documents from printing, forwarding, or copying of that sensitive information. The permissions that control these actions are actually stored directly within the documents themselves, and then IRM server performs the authentication. You can use Information Rights Management to restrict content wherever it is sent, and to set a file expiration.

When you set an expiration on a document, that document can no longer be viewed after the specified amount of time. You can also use IRM to enforce corporate policies governing the use and dissemination of content within your organization. Now, however, there are a few different things that you cannot do with Information Rights Management. For example, you can't use Information Rights Management to protect content from being erased, or stolen through attacks like Trojan horses or keystroke loggers. It also doesn't protect your documents from loss or corruption as a result of computer viruses.

And of course, as you might expect, IRM cannot protect documents from being photographed or hand-copied from a user's screen. It would be cool if it could, but it can't. Now, before you can use IRM to protect your documents, you have to first activate the Rights Management service, or RMS, features of your Microsoft 365 apps or services. Once you've activated the necessary Rights Management features, you can begin protecting your documents and emails. Information Rights Management integrates with several kinds of workloads in Microsoft 365, including SharePoint Online, Exchange Online, OneDrive, Microsoft Word, and others.

In the upcoming demonstrations, I'll show you how to set up rights management for several types of workloads.
