Diligent Cyber Security Begins When You Trust No One and Verify Everyone
“Zero trust is at the foundation of security transformation.” ~ Satya Nadella, Microsoft CEO
Zero trust is a security model that, as the name suggests, trusts no one by default and demands strict access control. It does not allow umbrella access to network servers and restricts movement within strict confines of stated perimeter, that too for a limited timeframe. The Microsoft Zero Trust security model challenges the traditional security model that protects the network perimeter with strict trust principles, but beyond that it gives relatively free movement access.
In 2021, 72% of organizations had plans to adopt the Zero Trust approach. ~ Statista
Zero Trust brings down the cost of a data breach by $1.76 million. ~ IBM
Close to 60% of SMEs in the UK and US are on their way to pursue a Zero Trust program. ~ Jumpcloud
Key Principles and Pillars of Microsoft Zero Trust Model
Zero trust model helps modern enterprises build an effective and adaptive security model that is particularly designed to meet the complex needs of today’s hybrid workplace while protecting enterprise security across the key technology pillars, based on the three guiding principles of the model — verify explicitly, grant least privileged access, and assume breach.
- Monitor workloads and flag any abnormal behavior
- Assign a compliance policy to every newly created workload
- Provide identity and limited conditional access only to users who need it for work
- Block and alert any unauthorized deployments
- Leverage granular visibility and access controls across workloads
- Use network segmentation and other tools to segment workloads
- Register all devices or endpoints with cloud identity provider
- Grant access to compliant devices only
- Enforce DLP policies on all endpoints
- Enable endpoint threat protection
- Ensure gated access control for both enterprise devices and BYOD
- Gain data and activity visibility in apps
- Restrict usage of unapproved apps
- Implement policies to protect sensitive data and activities
- Deploy stringent conditional access and verification for all apps
- Use cloud app security and similar tools to strengthen protection
- Monitor and assess security posture of the cloud environment
- Enable strong authentication
- Ensure conditional access is compliant
- Grant the least privileged access
- Know your data
- Take measures to prevent data loss
- Protect your organization data
- Govern your data and sensitive labels
- Network segmentation
- Threat protection

Zero Trust Deployment for Microsoft 365 Ecosystem
While Microsoft 365 is fundamentally designed with key security practices and data protection capabilities to ensure a Zero Trust environment, you can further extend many of the existing capabilities to protect your SaaS apps and data. Here’s how Zero Trust can be deployed from the bottom up to provide comprehensive, end-to-end protection.
Microsoft 365 productivity apps:
Pilot and deploy classification, labeling, information protection, and data loss prevention (DLP)
Create auto labeling rules
Create data loss prevention policies
Review/add sensitive information types and create sensitivity labels
Define data handling standards
Define data sensitivity schema
Defender for Identity
Defender for Microsoft Office 365
Defender for Endpoint
Defender for Cloud Applications
Pilot and deploy M365 Defender
Deploy Microsoft Intune configuration profiles to harden devices against threats
Configure Enterprise (recommend) Zero Trust identity and device access policies
Require healthy and compliant endpoints
Configure compliance policies
To be sure endpoints meet minimum requirements
Enroll endpoints into management
Configure starting point Zero Trust identity and device access policies
Turn on Multi-Factor Authentication and configure app protection policies that don’t require managing devices
Add SaaS apps to Microsoft Azure Active Directory or Microsoft Azure AD and include these in the scope of Multi-Factor Authentication policies
Configure cloud identity (cloud only, hybrid with PHS, hybrid with PTA, or federated)

Microsoft Zero Trust Security - FAQs
What is Zero Trust Security in Azure?
Microsoft’s Zero Trust Security is neither a product nor a solution. Zero Trust approach is a strategy developed by Microsoft to protect enterprise and customer data. Zero Trust Security follows a ‘trust no one, verify everyone’ approach as it secures every aspect of a digital estate on the basis of trusted user identities.
What are the three principles of Zero Trust Security?
Zero Trust security follows three key trust principles following the NIST guidelines—continuous and explicit verification, least privileged access, and assume breach which translates to always verify every access request from users, shrink down the blast radius by granting just enough access to users, and be always prepared for a breach to minimize impact on the organization, its systems and infrastructure.
What does Zero Trust prevent?
Zero Trust security prevents any attempt to access enterprise data or resources from inside or outside through constant verification as it trusts no one by default. Thus, it secures an organization's data, applications, IT infrastructure, endpoints, and systems from any security breach.
How relevant is Zero Trust in today’s environment?
Besides enhancing the security posture significantly, Zero Trust greatly brings down the cost and complexity of cybersecurity for the business and IT leaders by implementing a set of principles and practices. As Microsoft Zero Trust strategy is powered by automation, orchestration, and visibility, it becomes more relevant in the evolving threat landscape in today's cloud than ever.
