Notes

After each section of this blog, I will make a note of which of the 3 parts of the CIA Triad that Microsoft tool will help you meet.  Here are a few examples.

 

Example #1 –

Mapping Purview to OneDrive

For this part of the blog, I have broken down the Purview workloads, mapped them to the OneDrive activity, and then mapped those to the corresponding stage of the Information Lifecycle.

Here is the high-level view of this mapping.

Please note I’ve added a new stage to the Information Lifecycle and called it Pre-data creation.  This was done to help show that Microsoft Auditing is always enabled within your Microsoft tenant.

 

After each Purview workload, you will find a CIA triad “indicator” to show which part of the triad Purview is supported.  In addition, you will also find assorted links to assorted Microsoft documents or blog postings that can help you enable that functionality in your environment, presuming you are appropriately licensed.

 

 

Pre-data Creation

  1. Premium Audit (email/file) – It is recommended that this be enable before all functionality to watch all data activity in your environment.

Create (data)

  1. Premium Audit (email/file) – This watches the creation, user, searching, labeling (sensitivity and Retention labels), etc. of all data in your tenant.

  1. Information Protection (Sensitivity Label) (email/file/site) – This tool applies encryption, watermarking, access, editing, etc. based on a user’s credentials either in your tenant or associated with your tenant.  There are two ways that this tool can apply labels:
    1. Automatic Sensitivity labeling – This is done by the tool reasoning over data that exists or being created and applies a sensitivity label based on what it finds.
    2. Manual Sensitivity labeling – This is done by the user who applies a sensitivity label based what they see or have placed in that file/email.

  1. Data Lifecycle Management / Records Management (Retention Label) (email/file) – This tool applies retention based on what is inside of an email/file.  There are two ways that this tool can apply labels:
    1. Automatic Retention labeling - This is done by the tool reasoning over data that exists or being created and applies a retention label based on what it finds.
    2. Manual Retention labeling – This is done by the user who applies a retention label based what they see or have placed in that file/email.

Use & Retain (data)

  1. Premium Audit (email/file) – This is always logging interactions with files/emails.

  1. Data Loss Prevention (email/file) – This blocks sending emails/chats/data/files to the wrong individuals or organizations. 
    1. Example - your organization and your organization’s primary competitor.

  1. Information Protection (Sensitivity Labels) – This allows for manual/automatic sensitivity labeling of existing data OR changing sensitivity label of an existing label.
    1. An example of this would be encrypting files so only your Business partners can read the files using a user profile associated with your Azure Active Directory.  All other credentials, personal, competitor, etc. would be blocked from accessing the data.

  1. Data Lifecycle Management / Records Management (Retention label) (file/email) – These tools provide for either manual or automatic retention labeling of existing unlabeled data OR change the retention label of existing labels.
    1. Examples include applying a 7 year retention to PHI for HIPAA regulations, or changing a 7 year retention label to a 3 year retention when data within a file has been changed.

  1. Insider Risk Management (email/file) – This tool tracks data movement, deletion, changes in labels, exfiltration, etc  and maps it to user behavior.  If needed, this tool can hand collected information (emails, files, users name, etc) to eDiscovery as a case.
    1. An example of this would be a user tendering their resignation, and you see a sudden spike in their downloading corporate data to a USB stick.

Next Steps

We will now move to look at Teams and specific Purview workloads that can be mapped to data within that platform.
