Mastering Azure Tenant Configuration: CAPs and Intune Deployment

As financial institutions increasingly adopt Microsoft Azure for its robust capabilities, understanding how to configure your Azure tenant and implement effective policies is crucial. This blog post will explore the essentials of configuring an Azure tenant, how to implement Conditional Access Policies, and the key objectives for securely deploying Intune. We also delve into proper device and network maintenance.

Key Elements of Configuring an Azure Tenant

Azure tenant configuration includes defining user roles, managing subscriptions, and setting up security protocols that align with your institution’s needs. The key components to achieve this include:

• Conditional Access Policies (CAPs): These policies are essential for ensuring that only authenticated users and compliant devices can access systems.
• Entra ID: Microsoft’s identity platform where users, groups, devices, and CAPs are managed.
• Intune: Microsoft’s enterprise endpoint management product is used for managing devices and applications.

Conditional Access Policies and Exceptions

CAPs dictate how and under what conditions users can access the system. They can combine both the necessity to block certain access pathways and require additional authentication measures:

• Blocking Access: CAPs can efficiently block access by limiting unauthorized sign-in workflows, like blocking the use of legacy authentication or unauthorized locations. For instance, restricting access solely to the U.S. enhances security by preventing unauthorized logins from abroad.
• Requiring Additional Authentication: The policies may require multifactor authentication or device compliance. As financial institutions are prone to sensitive transactions, adding layers of verification protects user and consumer data effectively.

However, there may be scenarios where exceptions are necessary. For instance, a user traveling outside the country may need temporary access from a location typically restricted by your policies. In such cases, creating specific user groups and stacking policies can provide the necessary flexibility while maintaining security.

In addition to user-based exceptions, Conditional Access policies can be tailored for specific device access. This approach is particularly useful for managing remote or special-purpose devices that may not be fully integrated into your Active Directory. By configuring policies that permit access only from approved devices, you can enhance security and ensure that only these devices interact with your sensitive data.

Exceptions Examples:

• Group-Based Scoping: Instead of targeting individual users, use groups to manage exceptions efficiently.
• Country-Specific Access: Limit access to specific countries, when exceptions are required for users traveling abroad, only allow them access to defined country sets not the entire world. This enhances security while accommodating legitimate user needs.
• Device-Specific Access: Implement policies that allow access from only pre-approved devices.

Intune Objectives and Deployment

The deployment of Microsoft Intune represents a significant step in device and application management, particularly for community banks and credit unions aiming to secure their endpoints. The steps for successful deployment cover four primary objectives:

• Enrollment: Define which devices and platforms/operation systems (OS) can be enrolled and consider specific platform restrictions such as software version or manufacturer limits. For example, a good rule of thumb is to disable or block the use of operating systems you are not using.
• Compliance: Configure compliance settings such as minimum password length, whether to allow jailbroken devices or unofficial apps, etc. to establish your institution’s compliance standards. Check all devices against these benchmarks to identify non-compliant devices and then set CAPs to prevent sign ins on non-compliant devices.
• Application Whitelisting: Whitelist the applications that you want your users to be able to sign into with their work identities. This will require constant review and maintenance to ensure that only approved apps are available for work identities.
• Protection: Implement application protection policies to govern the usability of approved apps. The main goal is to prevent data exfiltration or data transfer between the apps. Some examples:
  • Data Boundary Establishment: Limit data transfer between applications to prevent unauthorized sharing.
  • Screen Capture Restrictions: Block the ability to capture screens as an image, mitigating the risk of data leaks.
  • Upload Restrictions: Prevent data from being uploaded to unmanaged cloud services, maintaining data integrity within the organization.

Device and Network Maintenance

Keeping systems updated and compliant with policy standards falls under everyday maintenance tasks. Ensuring certificates, particularly Apple Device Certificates, are renewed prevents devices from falling out of compliance, which is vital for continuity in operations. Ongoing management of your devices and network is vital for sustaining a secure Azure environment and includes:

• Certificate Renewal: Ensure that device certificates are up to date to maintain compliance.
• Version Management: Update device compliance policies to reflect the latest security patches and software versions.
• Stale Device Cleanup: Regularly remove devices that haven’t checked in to keep the system optimized.

Additionally, regular review of named locations for network access ensures that all authorized IP sets, such as those for backup internet services, are seamlessly integrated into your security framework, preventing potential access issues during outages.

Final Thoughts

Configuring and managing an Azure tenant requires a comprehensive approach to security and policy implementation. By understanding the intricacies of tenant configuration, Conditional Access Policies, and Intune deployment, your community bank or credit union can effectively safeguard data and maintain compliance. With these strategies in place, you can confidently navigate the challenges of Azure management and maximize the benefits of your cloud investment.
