MPM Q3FY20 - Surviving Common Office 365 Security Pitfalls — Is Your On-Premises AD the Weakest Link?

INTRODUCTION (cont.) Where should your security concerns be directed? Microsoft promises a financially-backed, 99.9% service-level agreement for Office 365—however, change control, access governance and overall data security is still the responsibility of customers. And the rise of hybrid AD compounds this concern. Think about this: 75% of Office 365 customers with more than 500 users will sync their on-premise AD with Azure AD, creating a hybrid AD environment. This scenario can lead to dangerous gaps and crippling inefficiencies. Any weaknesses in how the on-premise AD is configured will carry over to Azure AD. Organizations face all the security limitations of native AD and Azure AD, doubling the surface area they need to manage to prevent potential data breaches and insider threats. INTRODUCTION (cont.)

This eBook will identify steps for prepping the on-premise AD for synchronization with Azure AD, protecting data during migration and offer best practices for maintaining a more secure hybrid environment.
