Tutorial / Cram Notes

Conditional access is a crucial tool in securing your organization’s resources by controlling how users access these resources based on specific conditions. Implementing and managing conditional access policies ensures that only the right people under the right circumstances can access sensitive data, which is particularly relevant when preparing for the MS-100 Microsoft 365 Identity and Services exam.

Understanding Conditional Access:

Conditional access in Microsoft 365 is built on Azure Active Directory (Azure AD). It allows administrators to apply the right access controls when needed to keep the organization secure. Conditional Access policies are if-then statements; if a user wants to access a resource, then they must complete an action.

Key Components of Conditional Access Policy:

  • Assignments

    • Users or groups: Defines who the policy applies to.
    • Cloud apps or actions: Specifies the applications or user actions the policy applies to.
  • Conditions

    • Sign-in risk: Assess the risk level of a sign-in attempt.
    • Location: Define locations that are considered safe or risky.
    • Device: Target specific device types or states.
    • Applications: Set conditions based on the app being accessed.
  • Access Controls

    • Grant: Decide what the user needs to do to gain access, such as two-factor authentication.
    • Session: Apply session limitations, like restricted app access within a session.

Implementing Conditional Access Policies:

  1. Determine the Requirements: Define what resources need protection and the conditions under which access should be controlled.
  2. Create the Policy: Go to the Azure portal, navigate to Azure AD, select “Security” and then “Conditional Access”.
  3. Set Assignments: Choose the users or groups the policy will apply to and select the cloud apps or actions to include.
  4. Define Conditions: Determine the sign-in risk levels, locations, device states, or other conditions you want to enforce.
  5. Configure Access Controls: Specify what the user needs to do to gain access. This might include multi-factor authentication or limited session controls.
  6. Enable and Test the Policy: Initially, set the policy to ‘report-only’ mode to understand its impact before fully enforcing it.

Managing Conditional Access Policies:

  1. Update Assignments: Modify user and group assignments as your workforce changes.
  2. Review Conditions and Access Controls: Adjust policies based on evolving security threats or changes in the organizational environment.
  3. Audit and Monitor: Use the Azure AD Sign-in logs to monitor policy use and troubleshoot issues.
  4. Continuous Improvement: Use feedback from monitoring to refine your policies, ensuring they are effective without being overly restrictive.

Examples of Conditional Access Policies:

Example 1 – Require MFA for external access:

  • Assignments: All users except administrators
  • Cloud apps: All cloud apps
  • Conditions: Any location except the corporate network
  • Access Controls: Grant access but require multi-factor authentication

Example 2 – Block access from unmanaged devices:

  • Assignments: All users
  • Cloud apps: Select applications with sensitive information
  • Conditions: Device state as ‘unmanaged’
  • Access Controls: Block access

By implementing and managing conditional access policies, organizations taking the MS-100 exam can ensure that their administrators understand how to use these controls to protect their resources. These measures, when used effectively, deliver a balance between security and user productivity – a crucial aspect of managing modern enterprise environments in Microsoft 365.

Practice Test with Explanation

True or False: A conditional access policy can be applied to specific users or groups within your organization to enforce access requirements to cloud apps.

  • 1) True

Answer: True

Explanation: Conditional access policies can be targeted to specific users or groups to enforce different access requirements for cloud applications within an organization.

True or False: Conditional access policies can only be applied to user accounts and not to service principals or devices.

  • 2) False

Answer: False

Explanation: Conditional access policies can be applied to users, groups, service principals, and devices, depending on the conditions and access controls set by the administrator.

Which of the following conditions can be used in a conditional access policy? (Select all that apply)

  • A) User risk level

  • B) Device platform

  • C) Location

  • D) Organization’s stock price

Answer: A, B, C

Explanation: Conditional access policies can be configured based on user risk level, device platform, and location. The organization’s stock price is not a relevant or available condition for a conditional access policy.

To implement a conditional access policy, you must have at least one Azure AD Premium P1 license.

  • A) True

  • B) False

Answer: A

Explanation: Conditional access is a feature of Azure Active Directory that requires at least an Azure AD Premium P1 license.

True or False: It is possible to enforce multi-factor authentication as an access control in a conditional access policy.

  • 5) True

Answer: True

Explanation: Multi-factor authentication can be enforced as a control within conditional access policies to provide an additional layer of security.

What can be a possible action in a conditional access policy when a sign-in risk is detected?

  • A) Block access

  • B) Require password change

  • C) Grant access without restriction

  • D) Require multi-factor authentication

Answer: A, B, D

Explanation: When a sign-in risk is detected, a conditional access policy can block access, require a password change, or require multi-factor authentication. Granting access without restriction would not typically be an appropriate response to a sign-in risk.

Which Azure AD feature provides risk-based conditional access policies based on user behavior and potential security threats?

  • A) Azure AD Identity Protection

  • B) Azure Multi-Factor Authentication

  • C) Azure AD B2C

  • D) Azure AD Connect

Answer: A

Explanation: Azure AD Identity Protection provides risk-based conditional access policies that evaluate user behavior and potential security threats to protect the organization.

What should you use to enforce conditional access for Exchange Online based on device health?

  • A) Security defaults

  • B) Intune device compliance policies

  • C) Password protection policies

  • D) Azure AD Connect Health

Answer: B

Explanation: Intune device compliance policies can be used in conjunction with conditional access policies to enforce access based on device health for services like Exchange Online.

True or False: Once a conditional access policy is created, you cannot modify it.

  • 9) False

Answer: False

Explanation: Conditional access policies can be modified after they are created to adjust the organization’s security requirements or to address changes in the environment.

True or False: You can simulate the impact of conditional access policies using the ‘What If’ tool in the Azure portal.

  • 10) True

Answer: True

Explanation: The ‘What If’ tool in the Azure portal allows administrators to simulate and evaluate the impact of conditional access policies before actually deploying them.

Which of the following is NOT a valid session control in a conditional access policy?

  • A) Sign-in frequency

  • B) Persistent browser session

  • C) Application-enforced restrictions

  • D) Password hash synchronization

Answer: D

Explanation: Password hash synchronization is not a session control; it is part of the Azure AD Connect synchronization process. Session controls are mechanisms to manage user sessions after authentication such as sign-in frequency, persistent browser session, and application-enforced restrictions.

True or False: Conditional Access Policies are enforced after the first-factor authentication has been completed by a user.

  • 12) True

Answer: True

Explanation: Conditional Access Policies are evaluated and enforced after the first-factor authentication has been completed, helping to ensure that only the right individuals under the right conditions can access sensitive resources.
