Microsoft Security in Action: Deploying and Maximizing Advanced Identity Protection

As cyber threats grow in sophistication, identity remains the first line of defense. With credentials being a primary target for attackers, organizations must implement advanced identity protection to prevent unauthorized access, reduce the risk of breaches, and maintain regulatory compliance.

This blog outlines a phased deployment approach to implement Microsoft’s identity solutions, helping ensure a strong Zero Trust foundation by enhancing security without compromising user experience.

Phase 1: Deploy advanced identity protection

Step 1: Build your hybrid identity foundation with synchronized identity

Establishing a synchronized identity is foundational for seamless user experiences across on-premises and cloud environments. Microsoft Entra Connect synchronizes Active Directory identities with Microsoft Entra ID, enabling unified governance while enabling users to securely access resources across hybrid environments.

To deploy, install Microsoft Entra Connect, configure synchronization settings to sync only necessary accounts, and monitor health through built-in tools to detect and resolve sync issues. A well-implemented hybrid identity enables consistent authentication, centralized management, and a frictionless user experience across all environments.

Step 2: Enforce strong authentication with MFA and Conditional Access

Multi-Factor Authentication (MFA) is the foundation of identity security. By requiring an additional verification step, MFA significantly reduces the risk of account compromise—even if credentials are stolen.

Start by enforcing MFA for all users, prioritizing high-risk accounts such as administrators, finance teams, and executives. Microsoft recommends deploying passwordless authentication methods, such as Windows Hello, FIDO2 security keys, and Microsoft Authenticator, to further reduce phishing risks.

Next, to balance security with usability, use Conditional Access policies to apply adaptive authentication requirements based on conditions such as user behavior, device health, and risk levels. For example, block sign-ins from non-compliant or unmanaged devices while allowing access from corporate-managed endpoints.

Step 3: Automate threat detection with Identity Protection

Implementing AI-driven risk detection is crucial to identifying compromised accounts before attackers can exploit them. Start by enabling Identity Protection to analyze user behavior and detect anomalies such as impossible travel logins, leaked credentials, and atypical access patterns.

To reduce security risk, evolve your Conditional Access policies with risk signals that trigger automatic remediation actions. For low-risk sign-ins, require additional authentication (such as MFA), while high-risk sign-ins should be blocked entirely.

By integrating Identity Protection with Conditional Access, security teams can enforce real-time access decisions based on risk intelligence, strengthening identity security across the enterprise.

Step 4: Secure privileged accounts with Privileged Identity Management (PIM)

Privileged accounts are prime targets for attackers, making Privileged Identity Management (PIM) essential for securing administrative access. PIM allows organizations to apply the principle of least privilege by granting Just-in-Time (JIT) access, meaning users only receive elevated permissions when needed—and only for a limited time.

Start by identifying all privileged roles and moving them to PIM-managed access policies. Configure approval workflows for high-risk roles like Global Admin or Security Admin, requiring justification and multi-factor authentication before privilege escalation.

Next, to maintain control, enable privileged access auditing, which logs all administrative activities and generates alerts for unusual role assignments or excessive privilege usage. Regular access reviews further enable only authorized users to retain elevated permissions.

Step 5: Implement self-service and identity governance tools

Start by deploying Self-Service Password Reset (SSPR). SSPR enables users to recover their accounts securely without help desk intervention. Also integrate SSPR with MFA, so that only authorized users regain access.

Next, organizations should implement automated Access Reviews on all users, not just privileged accounts, to periodically validate role assignments and remove unnecessary permissions. This helps mitigate privilege creep, where users accumulate excessive permissions over time.

Phase 2: Optimize identity security and automate response

With core identity protection mechanisms deployed, the next step is to enhance security operations with automation, continuous monitoring, and policy refinement.

Step1: Enhance visibility with centralized monitoring

Start by Integrating Microsoft Entra logs with Microsoft Sentinel to gain real-time visibility into identity-based threats. By analyzing failed login attempts, suspicious sign-ins, and privilege escalations, security teams can detect and mitigate identity-based attacks before they escalate.

Step 2: Apply advanced Conditional Access scenarios

To further tighten access control, implement session-based Conditional Access policies. For example, allow read-only access to SharePoint Online from unmanaged devices and block data downloads entirely. By refining policies based on user roles, locations, and device health, organizations can strengthen security while ensuring seamless collaboration.

Phase 3: Enable secure collaboration across teams

Identity security is not just about protection—it also enables secure collaboration across employees, partners, and customers.

Step 1: Secure external collaboration

Collaboration with partners, vendors, and contractors requires secure, managed access without the complexity of managing external accounts. Microsoft Entra External Identities allows organizations to provide seamless authentication for external users while enforcing security policies like MFA and Conditional Access.

By enabling lifecycle management policies, organizations can automate external user access reviews and expirations, ensuring least-privilege access at all times.

Step 2: Automate identity governance with entitlement management

To streamline access requests and approvals, Microsoft Entra Entitlement Management lets organizations create pre-configured access packages for both internal and external users.

• External guests can request access to pre-approved tools and resources without IT intervention.
• Automated access reviews and expiration policies enable users retain access only as long as needed.

This reduces administrative overheads while enhancing security and compliance.
