Zero Trust and Identity Management - Implement Identity-First Approach

In the Zero Trust security model, identity is the first line of defense. As organizations adopt cloudbased infrastructure and remote work environments, managing and securing identities has become more critical than ever. Microsoft’s Zero Trust strategy places identity at the core of its architecture, ensuring that all access to resources—whether by users, devices, or applications—is thoroughly authenticated and authorized.

This article explores how Microsoft Zero Trust reinforces identity management and how OnCloud, as an experienced integration partner, can help design and deploy a robust identitycentric security model tailored to your organization’s needs.

The Role of Identity in Zero Trust Security

Identity in the Zero Trust model goes beyond just verifying usernames and passwords. Every access request is evaluated based on several risk factors, including:

User identity: Who is requesting access?
Location: Where is the user located?
Is this location consistent with their typical behavior?
Device health: Is the device compliant with security policies?
Application: What application is being accessed?
Risk and behavior: Is the user exhibiting unusual activity?

By verifying these factors, Zero Trust ensures that only the right people, on the right devices, can access your resources.

Microsoft’s Identity Solutions for Zero Trust

Microsoft provides a suite of identity solutions that align with Zero Trust principles, including:

Azure Active Directory (Azure AD): The cornerstone of identity management in the Microsoft ecosystem, Azure AD manages identities for users, devices, and applications.
MultiFactor Authentication (MFA): MFA adds an extra layer of security by requiring users to verify their identity through two or more verification methods.
Conditional Access: Azure AD Conditional Access policies allow organizations to enforce access decisions based on user, device, and application risk.
Identity Protection: This feature uses machine learning to detect suspicious behavior, prompting additional authentication steps when necessary.
Identity Governance: Managing permissions and roles through JustInTime (JIT) access and RoleBased Access Control (RBAC) to ensure users only access what they need.

How OnCloud Helps Implement Zero Trust Identity Management

Implementing a Zero Trust identity model involves more than just configuring software. It requires understanding your organization's security landscape and integrating these tools seamlessly into your environment. OnCloud brings its expertise in Microsoft solutions to help you through every step of the process:

Identity Assessment and Strategy Development

OnCloud starts by conducting a comprehensive security assessment to understand your organization’s current identity infrastructure. We’ll:

Analyze how your users access resources and which applications they interact with.
Identify key risks and gaps in your identity management systems.
Evaluate how your current access policies align with Zero Trust principles.

Based on this analysis, we’ll develop a tailored strategy for identity management within the Zero Trust framework, considering your unique security needs and operational goals.

Implementing Azure Active Directory (Azure AD)

At the core of Zero Trust identity management is Azure AD. OnCloud helps you deploy and optimize Azure AD by:

User and Group Management: Setting up and managing user identities, groups, and roles to ensure access is secure and controlled.
Conditional Access Policies: Configuring Conditional Access to grant or block access based on realtime risk factors such as user location, device compliance, and application usage.
Seamless SSO: Implementing Single SignOn (SSO) across your cloud and onpremises applications, ensuring users have secure, frictionless access to necessary resources.

These configurations help enforce identity verification consistently across your organization’s ecosystem.

Enforcing MultiFactor Authentication (MFA)

Passwords alone are not enough to secure modern organizations. OnCloud helps you strengthen authentication by:

Deploying MFA to reduce the risk of unauthorized access, using options like mobile app verification, biometrics, and hardware tokens.
Setting up adaptive MFA through Conditional Access policies, requiring MFA only in highrisk scenarios or for specific user roles.

MFA significantly increases your defense against phishing attacks and other credentialbased threats.

Identity Protection with Risk Based Policies

Microsoft’s Identity Protection uses AI to detect abnormal behaviors, such as login attempts from unfamiliar locations or devices. OnCloud helps:

Set up and customize riskbased policies to automatically challenge or block risky signins.
Configure automated responses to reduce risks in realtime, such as forcing a password reset after a highrisk event.

This adaptive identity protection helps ensure that even when credentials are compromised, access is prevented.

Implementing Identity Governance and Least Privilege Access

A critical component of Zero Trust is the principle of leastprivilege access—users should only have the minimum permissions required to perform their job. OnCloud assists by:

Implementing JustInTime (JIT) access: Granting temporary, timebound access to sensitive resources only when needed.
Using RoleBased Access Control (RBAC): Ensuring users are assigned roles that strictly align with their responsibilities, limiting unnecessary access.

This approach reduces the attack surface by minimizing overprovisioned accounts and restricting permissions to sensitive data and systems.

Secure Integration with Third Party Applications

Many organizations use a combination of Microsoft and nonMicrosoft applications. OnCloud ensures that:

Azure AD’s App Proxy is set up to secure access to legacy onprem applications.
All thirdparty apps are integrated with Azure AD to enable consistent identity verification and access control.
OAuth and SAML protocols are configured for seamless and secure authentication between systems.

This ensures your entire ecosystem, not just Microsoft products, operates securely under the Zero Trust model.

Ongoing Support and Monitoring

Identity management is an ongoing process. As your organization grows and new threats emerge, your security policies must adapt. OnCloud provides:

Continuous Monitoring: Setting up tools like Microsoft Sentinel for realtime identity threat detection and response.
Regular Reviews and Updates: Auditing Conditional Access policies, MFA settings, and identity configurations to ensure they stay aligned with best practices.
24/7 Support: Our team is available to assist with any issues, from user management to identitybased security incidents.

With OnCloud’s ongoing support, you can ensure your identity infrastructure remains secure and up to date as your organization evolves.

Conclusion

Identity is at the heart of Microsoft’s Zero Trust security model. By verifying and authenticating every user, device, and application, you can reduce the risk of breaches and protect your organization’s most valuable resources. However, implementing a robust identity management solution requires careful planning and expertise.

OnCloud, as a trusted Microsoft integration partner, is here to guide you through this transformation. From designing and implementing Azure AD and MFA to securing access with Conditional Access and governance, OnCloud provides endtoend services that align with Microsoft’s Zero Trust identity principles.
