Conditional Access is one of the crucial security concepts outlined in the SC-900 Microsoft Security, Compliance, and Identity fundamentals. It is a policy-based method of granting access to applications and data based on the clarification of certain conditions. Given its importance, it’s essential to understand what it is and how it works to succeed in the SC-900 exam.
What is Conditional Access?
Conditional Access is a capability of Azure Active Directory (Azure AD) that enables you to impose certain conditions for gaining access to applications. It’s not about denying or granting access rights; instead, it permits access, but with prerequisites that users must meet.
This is an important aspect of how Microsoft approaches its zero-trust network strategy and offers a balance between security and productivity. With Conditional Access, users have the liberty to work from anywhere, but they must satisfy the access conditions defined.
How Does Conditional Access Work?
Conditional Access works by applying conditions, and based on these conditions, subsequent actions concerning access either allow access, deny access, or require additional factors for verification.
The main components of a Conditional Access policy are:
- Users or groups: The targets to whom the policy applies.
- Cloud apps or actions: The related activities associated with the users.
- Conditions: The details regarding sign-in risk, device platform, network location, and client apps.
- Access controls: The measures taken based on conditions, either to grant access, request for multi-factor authentication, or deny access.
| Component | Description |
|---|---|
| Users or groups | Choose for whom the policy is applicable. It can be specific users, groups, or all users |
| Cloud apps or actions | Define what the policy impacts, either applications or user actions |
| Conditions | Determine the context under which the policy would be triggered |
| Access controls | Decide what actions to enforce once the conditions are met |
Examples of Conditional Access
For instance, an organization may set a Conditional Access policy that requires users to authenticate through multi-factor authentication (MFA) when trying to access a sensitive application from an unidentified device.
In this scenario, the ‘users and groups’ would be the employees of the organization, ‘cloud apps’ would be the sensitive application, ‘conditions’ would be an access attempt from an unidentified device, and ‘access controls’ would be the requirement for MFA.
Another example could be restricting access to cloud apps for users signing in from specific locations. For example, the policy could block a user trying to access an application from a geographical location that the company doesn’t operate from.
Conclusion: Importance of Conditional Access
Microsoft Security’s Conditional Access is much more than simply granting or blocking access. It offers a robust framework that determines ‘how’ users are getting access depending on ‘who’ is asking, ‘where’ they are asking from, ‘what’ they are accessing, and ‘how’ they are accessing it. Understanding and implementing Conditional Access is a vital skill assessed in the SC-900 Microsoft Security, Compliance, and Identity Fundamentals exam. It allows organizations to secure their resources while maintaining user productivity in a diverse, modern workspace.

Interview Questions
What is Conditional Access in Microsoft 365?
Conditional Access is a functionality in Microsoft 365 that enables you to define and enforce policies that regulate the access to your organization’s data. Such policies could consider factors such as device compliance, user risk level, or network location.
Which products does Microsoft Conditional Access integrate with?
Microsoft Conditional Access integrates with Azure Active Directory (Azure AD), Microsoft Intune, and Azure Information Protection.
What is the function of a Conditional Access policy?
A Conditional Access policy within Microsoft Azure is used to implement conditional access to resources. This policy ensures that specified conditions are met before granting access to a resource, such as a user’s sign-in risk, location, device state and client application.
Name one benefit of using Conditional Access in Microsoft 365?
One key benefit of using Conditional Access is that it helps organizations prevent unauthorized access to sensitive data and manage risk by ensuring conditions for access are met.
What is the principal Condition in Azure AD Conditional Access policy?
The principal Condition in Azure AD Conditional Access policy includes User or group, IP location, Device platform, Device state, Sign-in risk, and Client apps.
What is the purpose of ‘Assignments’ in Conditional Access policy?
‘Assignments’ in a Conditional Access policy is to define the users, groups, cloud apps, and other conditions for which the policy applies.
What is the ‘Access control’ in a Conditional Access policy?
‘Access control’ in a Conditional Access policy is to define the controls that are enforced after the users’ sign-in request meets the conditions defined in ‘Assignments’. These controls can either grant or block access or prompt for multifactor authentication.
Can Conditional Access be applied to guest and external users?
Yes, Conditional Access in Microsoft 365 can be applied to guest and external users. This helps secure your organization’s data even when accessed by these users.
How many Conditional Access policies can you create in Microsoft 365?
You can create up to 1940 Conditional Access policies per tenant in Microsoft 365.
What are ‘Named locations’ in Conditional Access policy?
Named locations in Conditional Access policy are defined by the administrator to represent a geographic location. These named locations can then be included in Conditional Access policy conditions to control access based on network location.
How is Conditional Access different from Azure AD Multi-Factor Authentication (MFA)?
Azure AD MFA is a method for verifying a user’s identity, while Microsoft Conditional Access is a tool for defining and enforcing access policies based on certain conditions such as user location or device security status.
What role does Microsoft Intune play in Conditional Access?
Microsoft Intune is used in Conditional Access to assess the compliance of a device before it can access resources, hence playing a pivotal role in device-based Conditional Access.
Does the implementation of Conditional Access imply that firewall rules are not necessary?
No, Conditional Access does not replace firewall rules. It adds an additional layer of security to data and resources, but should be used in combination with other security measures such as firewalls.
What happens if multiple Conditional Access policies apply to a particular scenario?
If multiple Conditional Access policies apply to a particular scenario, all of the policies are evaluated for their result. If any policy blocks access, the sign-in is blocked.
Can Conditional Access policies be applied to on-premises applications?
Yes, Conditional Access policies can be applied to on-premises applications using Azure AD Application Proxy or third-party solutions integrated with Azure AD.
