Did you know: Exact Data Match (EDM) will support salt in the data hashing process to improve data security.
- Microsoft 365 Roadmap ID: 65207
- Timing: August 28, 2020
- Action: review and assess
How this will affect your organization
Adding a random string, known as a salt, to each data value prior to hashing can make it much more challenging for an attacker to reverse engineer the original values. Customers can choose to use a custom salt or a random salt that is generated by Microsoft.
The data hashed and uploaded for EDM will be more secure through the addition of the salt to the hashing process.
What you need to do to prepare
Once the feature is available, download and install the appropriate updated EDM Upload Agent (Commercial/GCC, GCC-High, or DoD). Updated Upload Agents will be available when the feature reaches GA.
If you had previously hashed, indexed, and uploaded data to the EDM service and are already using EDM and would like to add salt to that hashed data, you will need to re-hash and re-upload that data using the instructions provided on the EDM page.
