As of 2023, Microsoft Office 365 is utilized by over a million companies globally, according to a recent Statista report. It has become an indispensable tool for organizations as they adapt to hybrid workforces and a global economy, leveraging its collaborative power and the need for a robust data protection strategy. At the core of Microsoft 365’s security framework lies the Shared Responsibility Model, delineating the responsibilities of Microsoft and organizations using their services. Understanding this model is imperative for securing and protecting your organization’s data within the Microsoft 365 environment.
Understanding the Microsoft 365 Shared Responsibility Model
Consider the Microsoft Shared Responsibility Model as a guide to help you understand the components and tasks your IT team is responsible for in your organization’s IT environment. At a high level, Microsoft is responsible for securing the services they provide you—the customer—and you are responsible for securing your organization’s data and applications. So, what does that mean?
Microsoft’s Role in Security and Compliance
Microsoft provides a range of measures to safeguard the integrity and availability of Microsoft 365 and your organization’s data. Here’s a summary of Microsoft’s key responsibilities:
- Uptime Guarantee: Microsoft commits to maximum uptime for the infrastructure and software supporting Microsoft 365.
- Data Replication: Microsoft employs data replication across multiple locations to enhance data availability and reliability. However, Microsoft’s data replication does not protect against accidental user data deletion, emphasizing the need for a comprehensive backup strategy.
- Setup and Management: Microsoft takes responsibility for configuring and managing the infrastructure hosting Microsoft 365. This includes protection against various potential disruptions, such as electrical failures, natural disasters, physical threats, and other issues that could impact service availability.
- Access Control: Microsoft provides robust access controls, including multi-factor authentication (MFA) alongside traditional password-based authentication, strengthening the security posture of Microsoft 365.
Customer’s Role in the Shared Responsibility Model
Ultimately, customers play a crucial role in safeguarding their data in Microsoft’s Shared Responsibility Model. Here’s a condensed overview of the customer’s role:
- Guarding Against Internal and External Threats: Customers are tasked with safeguarding their data from intentional deletions by employees and external threats such as ransomware attacks.
- Mitigating Accidental Data Deletion: Microsoft 365 does have a recycling bin for accidental data loss prevention, but it is limited and temporary storage.
- Meeting Data Retention Requirements: Customers are responsible for aligning their data retention policies with laws and internal company guidelines.
- Ensuring Regulatory Compliance: Customers are responsible for managing sensitive data in accordance with regulatory policies.
While Microsoft manages the infrastructure, it doesn’t absolve you of the responsibility to back up essential Microsoft 365 data crucial for your business. And as you can see, the Microsoft Shared Responsibility Model puts a lot of onus on the customer and their internal IT organization for compliance and maintaining a resilient security posture.
