Information Rights Management (IRM) is the management of a users right to information. Do they have the right permission to work with this file? Within Microsoft you can setup labels, and apply restriction policies to these labels. For example a email or document tagged as 'confidential' may prevent the user from edited, printing, downloading, or forwarding it. If the user tries to copy and paste some content the paste action will be blank, if they try to screenshot it will turn out black and even taking a photo of the screen applies an invisible watermark to identify which authorized user had it open when the photo was taken.
Common labels include public, internal, financial and confidential, and can be applied manually during email/document creation, to whole libraries/folders or automatically by policies that look for specific triggers; for example if bank details are detected, it automatically applied the financial label to prevent editing or forwarding.

Historically when you need to share a document with someone, you email it to them as an attachment. SharePoint Online stores the files in a central company Document Management System and instead of emailing a copy for them to edit and send back, you can send them a link to the file so that you can co-work on the same file at the same time. There will be no more version discrepancies or lost copies. This blog will show you how you can share these document links from the various places you will work with a document within SharePoint.
1. Go to the OneDrive or SharePoint and sign in with your account.
2. Select the file or folder you want to share and then select Share.
3. Click on the arrow (>) to change with whom you want to share the document. Select Specific people under Link settings and click Apply.
By default, Allow editing is turned on. If you want people to only view your files, uncheck the check box.
