Tutorial / Cram Notes
Conditional access is a core component of the security features within Microsoft 365, which helps organizations enforce access controls to their applications and data. It is essentially a set of policies and configurations that administrators can use to determine who can access resources, under what conditions, and what they can do with those resources.
The primary purpose of conditional access is to provide enhanced security by ensuring that only authorized users can access sensitive information and that they do so in a secure manner. This involves evaluating several signals such as user identity, device health, location, and risks associated with a user or device to make real-time decisions on access.
Value of Conditional Access:
- Improved Security Posture: By implementing conditional access policies, organizations can significantly reduce the risk of unauthorized access and data breaches. Conditional access ensures that only trusted users and devices complying with the organization’s policies can access resources, even if credentials are compromised.
- Adaptive Access Controls: Conditional access allows policies to adapt to real-time contextual information such as login behavior, device compliance status, and network location. This flexibility ensures a balance between security and user productivity by applying the right level of control based on the assessed risk.
- Simplified User Experience: Users benefit from conditional access policies through seamless access to resources without unnecessary security hurdles when they comply with security requirements. This can also lead to fewer help desk calls and increased user satisfaction.
- Compliance and Regulatory Requirements: Many industries have specific requirements about data access and privacy. Conditional access policies can be tailored to meet such regulatory demands, helping organizations to maintain compliance and avoid potential legal and financial penalties.
- Automated Enforcement: Once conditional access policies are set up, they are automatically enforced by the system. This automation saves time for IT administrators and reduces the human errors associated with manual security checks.
Examples of Conditional Access Policies:
- Require MFA for External Users: A policy can be set so that multi-factor authentication (MFA) is prompted when a user tries to access a resource and is detected to be outside the corporate network. This helps protect against unauthorized access from potentially unsecure locations.
- Block Access from Non-compliant Devices: Access to corporate data can be blocked on devices that do not comply with the organization’s security baseline, such as having the latest antivirus updates or being encrypted.
- Grant Access Based on Risk Level: Utilizing Azure AD Identity Protection, a policy could only allow access to resources if the sign-in risk is assessed to be low. If the risk is higher, further verification or denial of access can be automatically triggered.
- Location-based Restrictions: Access to certain sensitive applications might be restricted to the organization’s physical locations by defining trusted IP address ranges.
Comparison of Conditional Access Scenarios:
| Scenario | Access Control | Example Use Case |
|---|---|---|
| Always require MFA | Enforce MFA regardless of other signals | Access to high-value resources, e.g., financial applications |
| Risk-based conditional access | Require stronger authentication or block access based on risk | User signs in from an unusual location |
| Require compliant devices | Only allow access from devices that meet compliance standards | Users attempting to access data from personal devices |
| Block legacy authentication | Prevent sign-ins from legacy protocols which don’t support MFA | Blocking access via outdated mail protocols like POP/IMAP |
| Allow limited access (session control) | Provide limited, web-only access without ability to download data | Users accessing from BYOD or unmanaged devices |
Conditional access in Microsoft 365, as demonstrated through the scenarios above, serves as both a defense mechanism against potential security breaches and a flexible, intelligent system to facilitate productivity without sacrificing security. The MS-900 Microsoft 365 Fundamentals exam would test an understanding of these concepts, ensuring that candidates are familiar with the basic principles and value of such access policies.
Practice Test with Explanation

- C. To protect against unauthorized access to resources
- D. To ensure compliance with corporate security policies
Answer: B, C, D
Conditional Access is used to apply automatic access controls, protect against unauthorized access, and ensure security policies are adhered to, not to provide unlimited access.

- Answer: True
Conditional Access policies can be targeted to specific roles, groups, or even specific users.
What is the primary value of implementing Conditional Access in a cloud environment?
- A. Increases the complexity of the environment
- B. Reduces the need for strong authentication methods
- C. Enhances security by ensuring the right conditions are met before access is granted
- D. Allows all users to access all services without any restrictions
Answer: C
The primary value is enhancing security by ensuring that the necessary conditions are met before granting access to resources.
True or False: Conditional Access Policies can only be applied to user accounts and not service accounts.
- Answer: False
Conditional Access policies can be applied to both user and service accounts within an organization.
What does Conditional Access use to enforce access controls? (Choose all that apply)
- A. User risk
- B. Physical location
- C. Time of day
- D. Device compliance
Answer: A, B, C, D
Conditional Access uses signals such as user risk, location, time of the day, and device compliance to enforce access controls.
True or False: Once a Conditional Access policy is set, it cannot be updated or removed.
- Answer: False
Conditional Access policies are not permanent and can be updated or removed based on the evolving needs of an organization.
Conditional Access policies are an example of which of the following security approaches?
- A. Perimeter-based security
