SC-100: Microsoft Cybersecurity Architect Practice Test 2025

Based on the outline provided for the SC-200: Designing and Building Cloud Security Solutions exam (formerly SC-100), which focuses on designing security solutions within Microsoft's cloud ecosystem, here are some insights and considerations for each section:

Design solutions for securing privileged access

• Assigning and delegating privileged roles: Utilize Azure Role-Based Access Control (RBAC) to assign roles that grant the least privilege necessary to perform required tasks.
• Identity governance solution: Implement Microsoft's Privileged Identity Management (PIM) to manage privileged identities, along with entitlement management and access reviews to ensure principle of least privilege is maintained.
• Securing cloud tenant administration: Use Azure Lighthouse for managing access across multiple subscriptions and Azure AD External Identities for secure collaboration with external users.
• Privileged Access Management (PAM): Integrate with solutions like Azure Arc to manage privileged access across hybrid, multicloud, and on-premises environments.

Design solutions for regulatory compliance

• Translate compliance requirements: Understand the specific regulatory frameworks that apply to your organization, such as GDPR or HIPAA, and translate those into actionable security controls.
• Solution using Microsoft Purview: Leverage Microsoft Purview to help manage data and ensure compliance with privacy regulations.
• Azure Policy: Use Azure Policy to enforce compliance with security baselines and compliance standards across all cloud resources.
• Security posture evaluation: Utilize tools like Microsoft Defender for Cloud to continuously monitor and improve the security posture of your cloud environment.

Design security solutions for infrastructure

• Hybrid and multicloud environments: Ensure consistent security policies are applied across different environments using Azure Policy and security tools like Defender for Cloud.
• Security posture management (SPM): Implement SPM solutions that provide a holistic view of your cloud estate's security, including compliance scores and vulnerability assessments.
• Data in Azure workloads: Secure data at rest by using Azure Disk Encryption, and in motion with Azure Private Link and Network Security Groups (NSGs).

Design solutions for securing Microsoft 365

• Microsoft 365 Defender: Monitor and protect identities, endpoints, emails, and data across Microsoft 365 workloads.
• Secure configurations for Microsoft 365: Implement best practices for configuring security and compliance settings in Microsoft 365.

Design solutions for securing applications and data

• Application security: Integrate application security into the software development lifecycle (SDLC) using standards like OWASP and leverage tools like Application Security Groups (ASGs) in Azure.
• Data discovery and classification: Use Microsoft Purview to classify data and understand where sensitive data is located.
• Protection of data at rest, in motion, and in use: Employ encryption solutions for data at rest (like Azure Disk Encryption), secure data in transit with VPNs or ExpressRoute, and use Azure Information Protection for data in use.

General Considerations

• Threat modeling: Regularly perform threat modeling to identify potential vulnerabilities in applications and infrastructure.
• API management and security: Secure APIs using Azure Front Door Service (AFDS) and WAF policies to protect against common web threats.
• Workload identity: Use Workload Identities in Azure Active Directory to securely access resources without sharing credentials.

Conclusion

To prepare for the SC-200 exam, you should focus on understanding Microsoft's suite of security and compliance tools, as well as best practices for securing cloud infrastructure, applications, and data. Practical experience with these services in a lab or real-world environment will be invaluable. Additionally, staying up-to-date with the latest updates and features from Microsoft will help ensure that your design and security solutions are effective and compliant with industry standards.
