Tutorial / Cram Notes
Access reviews help organizations maintain least-privilege access principles, remain compliant with regulations, and reduce the risk of security breaches. Regularly reviewing access rights ensures that users only retain access to resources they require for their current role and responsibilities.
Overview of Access Review Process
The access review process in Azure Active Directory (Azure AD) involves the following steps:
- Define the scope: Decide which resources and identities require periodic review.
- Determine review frequency: Establish how often the access reviews should occur based on organizational requirements and regulatory mandates.
- Select reviewers: Identify who will perform the reviews. Reviewers can be resource owners, group owners, or other designated individuals.
- Decide on review outcomes: Define what should happen when access is approved or denied; for example, whether to remove access immediately or after a certain period.
- Monitor and report: Track the review progress and outcomes, and ensure that appropriate actions are taken based on the review decisions.
Planning for Access Reviews
Defining the Scope and Frequency
| Resource Type | Review Frequency | Justification |
|---|---|---|
| High-impact applications | Quarterly | Ensure critical resources are protected |
| Standard groups and applications | Semi-annually | Balance between security and operational overhead |
| Temporary access permissions | After each project or event ends | Reduce the risk of orphaned permissions |
Identifying Reviewers
Choosing the right reviewers is essential for accurate access review outcomes. Reviewers should have knowledge of the user’s role and access needs.
Access Review Policies
Policies should outline what happens during and after the review process. They should include guidance on actions to take for approvals, denials, and when there’s no response from the reviewers.
Automated or Manual Reviews
Determine if reviews will be automated or manual. Automated reviews can leverage pre-defined policies to streamline the process, while manual reviews provide a more hands-on approach.
Example of Planning Access Reviews
Consider a scenario where a company uses Azure AD to manage access to its cloud applications.
- The IT team defines the scope by identifying which applications are critical and require quarterly reviews.
- They schedule semi-annual reviews for other groups.
- Owners of the respective applications and groups are designated as reviewers.
- Policies dictate that if access is not confirmed during the review, it’s to be removed after a 7-day grace period.
- The team uses Azure AD’s built-in review features to automate reminders and reporting.
Implementation with Azure AD
Azure AD provides tools for implementing access reviews:
- Azure AD Access Reviews: Configure access reviews for groups, applications, and roles.
- Access Review Policies: Create policies for how and when users are reviewed.
- Automated Review Management: Automate the access review process with rules and schedules.
- Reporting and Monitoring: Utilize Azure AD’s reporting capabilities to track and analyze the outcomes of access reviews.
Access Review Best Practices
- Regular Reviews: Schedule access reviews regularly to maintain updated permissions.
- Clear Documentation: Maintain clear documentation for audit purposes and future reference.
- Communication: Keep all stakeholders informed about the access review process and outcomes.
Conclusion
Effective access reviews are a cornerstone of identity and access management. By establishing a structured access review plan and utilizing the capabilities of tools like Azure AD, organizations can ensure that access rights are kept up-to-date and that security and compliance requirements are continually met. As the SC-300 Microsoft Identity and Access Administrator exam emphasizes, professionals should be adept at planning, implementing, and managing access reviews to maintain robust identity governance within their organizations.
Practice Test with Explanation
True or False: Access reviews in Azure AD are used to review user assignments to groups Only.
- Answer: False
Explanation: Access reviews in Azure Active Directory can be used to review user assignments to groups, applications, and role assignments, not just groups.
When planning for access reviews, which of the following should be considered? (Select all that apply)
- A) Group memberships
- B) Application access
- C) Role assignments
- D) Storage account access
- E) Review frequency
Answer: A, B, C, E
Explanation: When planning for access reviews, group memberships, application access, role assignments, and review frequency should be considered. Storage account access is not directly related to Azure AD access reviews.
True or False: An access review policy can only be applied to one resource at a time in Azure AD.
- Answer: False
Explanation: An access review policy can be applied to multiple resources. You can configure access reviews for multiple targets such as groups, applications, and role assignments within the same or separate policies.
Who can perform an access review in Azure AD? (Single select)
- A) Any user in the organization
- B) Global administrators only
- C) Selected reviewers assigned by an administrator
- D) External guests only
Answer: C
Explanation: Selected reviewers, who can be users or groups assigned by an administrator, perform the access review. Depending on the settings, the review could potentially be performed by the resources’ owners or members as well.
True or False: Once an access review is started, its settings cannot be modified until the review is complete.
- Answer: True
Explanation: After an access review starts, its settings are locked, and you must wait for that review cycle to finish before making modifications.
Which types of Azure AD resources can have their access reviewed? (Select all that apply)
- A) Users
- B) Groups
- C) Applications
- D) Virtual Machines
- E) Role assignments
Answer: B, C, E
Explanation: Azure AD access reviews can be performed on group memberships, application access, and Azure AD role assignments. Users are reviewed within these resources, and virtual machines are not directly reviewed as they are not Azure AD resources.
When are access reviews considered necessary? (Single select)
- A) Only during internal audits
- B) Periodically, to ensure compliance and least-privilege access
- C) Once a year during employee appraisals
- D) Never, as Azure AD automatically manages access
Answer: B
Explanation: Access reviews should be performed periodically to ensure that users have the correct access necessary for their roles, helping maintain compliance and instituting least-privilege access principles.
True or False: It is possible to automate responses to access reviews in Azure AD.
- Answer: True
Explanation: Responses to access reviews can be automated using Azure AD’s auto-review settings, which can approve or deny access based on the conditions set.
In Azure AD, what is a major benefit of setting up recurring access reviews? (Single select)
- A) Decreases the workload of IT staff
- B) Increases storage costs
- C) Guarantees no unauthorized access
- D) Provides continuous insight into access privileges and potential risks
Answer: D
Explanation: Recurring access reviews provide continuous insight into access privileges and can highlight potential access-related risks, which helps in maintaining security and compliance.
True or False: Guest users are exempt from access reviews in Azure AD.
- Answer: False
Explanation: Guest users are not exempt from access reviews. They can be included in reviews to help ensure that they have appropriate access.
What happens if no action is taken on an access review before it ends? (Single select)
- A) The access review is automatically deleted.
- B) Access for users is automatically approved.
- C) Access for users is automatically denied.
- D) The default or fallback decision is applied.
Answer: D
Explanation: If no action is taken, the default decision defined in the review policy (approve, deny, or leave unchanged) is applied to the users at the end of the access review.
True or False: Only Azure AD Premium P2 licenses are required for all users reviewed in access reviews.
- Answer: False
Explanation: Azure AD Premium P2 licenses are required only for the users who are being reviewed if they need to use advanced features like access reviews. However, if the reviewers are only reviewing access and not acting on it, then they would not necessarily need a P2 license.
