Microsoft 365 deployment strategy for Zero Trust

Zero Trust implementation for Microsoft 365

Microsoft 365 was purposefully designed with a wide range of security and information protection features to aid you in implementing Zero Trust in your environment. Many of the features may be expanded to safeguard both the data in other SaaS apps that your company uses and the users’ access to them.

The task of implementing Zero Trust capabilities is shown by this graphic. To guarantee that prerequisite work is finished, this task is divided into pieces of work that may be constructed together, working from the bottom up.

The Microsoft 365 Zero Trust deployment stack

In this instance:

  • The core of Zero Trust is identity and device protection.
  • On top of this base, threat prevention capabilities are created to enable real-time monitoring and security threat mitigation.
  • Information protection and governance offer complex controls focused at certain categories of data to safeguard your most important data and assist you in adhering to compliance regulations, such as safeguarding personal data.

Step 1 :Configure Zero Trust identity and device access protection — Default policies as the first step.

Building your Zero Trust foundation by establishing identity and device access protection is the first step.

The process to configure Zero Trust identity and device access protection

Visit Zero Trust identity and device access protection for further instructions on how to do this. In order to secure access to Microsoft 365 for enterprise cloud apps and services, other SaaS services, and on-premises applications published with Azure AD Application Proxy, a set of identity and device access prerequisite configurations, a set of Azure Active Directory (Azure AD) Conditional Access, Microsoft Intune, and other policies are described in this series of articles.

Implement the starting-point tier first. It is not necessary to enroll devices in management under these regulations.

Step 2. Manage endpoints with Intune

After that, add your devices to management and start securing them with more advanced controls.

The Manage endpoints with Intune element

 

Go to Manage devices with Intune for prescriptive guidance to accomplish this.

Includes Prerequisites Doesn’t include
Enroll devices with Intune:

  • Corporate-owned devices
  • Autopilot/automated
  • enrollment

Configure policies:

  • App Protection policies
  • Compliance policies
  • Device profile policies
Register endpoints with Azure AD Configuring information protection capabilities, including:

  • Sensitive information types
  • Labels
  • DLP policies

For these capabilities, see Step 5. Protect and govern sensitive data (later in this article).

Step 3: Include enterprise policies that guard against Zero Trust identity and device access.

You may now deploy the complete range of advised Zero Trust identity and device access policies, necessitating compatible devices, after the devices have been registered into management.

Return to Common identity and device access policies and add the policies in the Enterprise tier.

Step 4:Test, try out, and use Microsoft 365 Defender.

In your Microsoft 365 ecosystem, including endpoints, email, apps, and identities, Microsoft 365 Defender is an extended detection and response (XDR) solution that automatically gathers, correlates, and analyses signal, threat, and alert data.

Step 5: Guard and control delicate data

To find, categorise, and secure sensitive information wherever it resides or travels, use Microsoft Purview Information Protection.

You have the ability to understand your data, safeguard your data, and stop data loss thanks to Microsoft Purview’s information protection features, which are provided with the software.

Although this task is shown as being at the top of the deployment stack in the article’s earlier illustration, you can start it at any moment.

You may use the structure, procedure, and capabilities offered by Microsoft Purview Information Protection to achieve your unique company goals.
