The last section of Classifications lists the available types, which we saw earlier when looking through labeling policy templates. This list is basically display-only, but it is possible to add your own types to the list.
The creation of custom-sensitive information types is a very advanced topic, so going into detail is beyond the scope of this book. If you choose to do so, you will need the following skills:
- Business knowledge of search criteria and document classification strategies
- Regular expressions (RegEx)
- PowerShell commands to upload the custom type to Office 365
