DLP Policy Slow to Screen New Files in OneDrive For Business and SharePoint Online
Hello Everyone,
I have enabled some DLP policies in Office 365 security center, and these apply to OneDrive for business and SharePoint Online.
So far these policies are working and preventing data from getting shared to un-authorized recipients. However, if I create/upload a new file in my OneDrive For Business, I can share the file with external people within the first 10 to 15 minutes of upload/create. After about 10-15 minutes the DLP policy kicks in and locks down the new file, but it's too late, the file is already shared!
Any idea how to force new files to get scanned by the DLP policy engine immediatly?
Thanks,
Robert
At the very least, the document needs to be crawled by the search engine, which in SPO can take a while (I believe the minimum guarantee is around 15 mins, but it can take a lot less or lot more depending on the overall load).
The way DLP policies work against SPO/ODFB content is detailed here: https://support.office.com/en-us/article/Overview-of-data-loss-prevention-policies-1966b2a7-d1e2-4d92-ab61-42efbb137f5e?ui=en-US&rs=en-US&ad=US
- aniyahimaCopper ContributorHi, I have the same issue but in this case it takes more than 24 hours and to scan new files it takes more than 3 days, that is crazy. The link you provide it has a 404 Not found. Any idea how can we force to scan all my tenant in search of a matched rule or policy?
- Robert MarshallCopper ContributorHi Vasil,
Thank you for your reply. This is unfortunate, as my organization is a financial institution. We value DLP over user productivity because the data we have simply can't get leaked. It seems the only way to guarantee that sensitive data won't get shared is to keep it on premise. Hopefully Microsoft will introduce a feature that can disallow sharing until DLP clears a document.Well if memory serves, the document will get locked upon detecting any DLP policy matches, so even if it was shared during that short interval, it will not be accessable by external users.
