8 Microsoft Office 365 Security Tips To Reduce Data Loss

Even with a slew of new security tools and compliance guidance, there are still things you can do to protect this critical business system.
3 of 9

RISK: Sensitive data could leak within Office 365

Sensitive data leakage is a big concern for organizations that have moved to or are in the process of moving to Office 365. Whether the organization is worried about unauthorized access and/or unintended exposure of private health information (PHI), protected credit card data, or the company's intellectual property (IP), data protection should be a big focus when looking to adopt Office 365.

The security action required to address this risk is to deploy a cloud-access security broker that can support cloud-based data loss prevention. This can help identify sensitive data that is already resident in OneDrive and SharePoint along with sensitive data that is uploaded, downloaded or shared in real time. To eliminate blind spots, it is also important that the CASB supports the ability to see details of all Office 365 traffic whether the usage originates from a web browser, mobile app, OneDrive sync client, or even one of the Office 365 ecosystem apps. Finding sensitive data is the first step; putting a quarantine or 'block' policy in place to prevent it from leaking is the follow-on mitigating control.
