Encryption is one feature offered by Microsoft Office that allows the users to change the permissions and access levels of others to the files. Using this feature, it is possible for us to make the file read only, add a digital signature, restrict editing and encrypt it with a password.

First of all, open the file menu, present on the top right hand corner of the screen and find the protect document button. Press it to reveal more options. 
You can either set the file as read only. It makes a non-editable copy for the document you are working on.

For those willing to digitally sign the document, add a digital signature button can be used. If you don't know what digital signatures are, then probably you don't need one.
The screens you see in your edition of Microsoft office might be a little different from the ones shown here. The screenshots attached here are captured on Microsoft Office 365.
Make sure you stay a step ahead the next time someone tried to steal or access your documents without permission.
