Tutorial / Cram Notes
Microsoft Sentinel provides several roles that delineate what actions a user can perform in the platform. These roles are based on Azure role-based access control (RBAC), which allows fine-grained access management. Below are the key roles associated with Microsoft Sentinel:
1. Microsoft Sentinel Contributor
This role allows the user to perform most Microsoft Sentinel management tasks, such as creating and managing incidents, workbooks, notebooks, and playbooks. However, Sentinel Contributors cannot manage access to Microsoft Sentinel resources.
2. Microsoft Sentinel Reader
A user with the Sentinel Reader role can view all Microsoft Sentinel data, including alerts, incidents, and dashboards, but cannot make changes.
3. Microsoft Sentinel Responder
A Sentinel Responder can take action on incidents. This includes changing the status of incidents, adding comments, and managing tags. They do not have permissions to modify analytics rules or other configurations.
4. Microsoft Sentinel Automation Contributor
This role allows the user to create and manage automation rules and playbooks within Microsoft Sentinel, which are vital in setting up automatic responses to threats.
How to Configure Microsoft Sentinel Roles
To assign roles to a user or a group, you must have sufficient permissions yourself, usually as an Azure subscription owner or user access administrator. Here is how you can configure roles within Microsoft Sentinel:
- Navigate to the Azure Portal: Go to the Azure portal at https://portal.azure.com and sign in with an account that has the necessary permissions.
- Open Microsoft Sentinel: In the Azure portal, search for and select Microsoft Sentinel, then on the Microsoft Sentinel workspace page, select the appropriate workspace.
- Access the IAM (Identity and Access Management) Blade: Click on the ‘Access control (IAM)’ option from the Sentinel workspace menu.
- Add Role Assignments: Click on ‘+ Add’ and then select ‘Add role assignment’ to start assigning a role.
- Select a Role: Choose the specific Sentinel role you want to assign from the list that pops up (Sentinel Contributor, Sentinel Reader, Sentinel Responder, or Sentinel Automation Contributor).
- Assign to a User or Group: Search for the user or group you want to assign the role to in the ‘Select’ pane and choose them.
- Review and Assign: Review your choices and click ‘Save’ to apply the role assignment.
Best Practices for Role Assignments in Microsoft Sentinel
- Least Privilege Access: Assign users only the permissions they need to perform their tasks. For example, if a user only needs to view alerts, then the Sentinel Reader role would be appropriate.
- Periodic Review of Access Rights: Regularly review who has access to what, ensuring that ex-employees or transitioned employees do not retain access.
- Multi-Factor Authentication (MFA): Enforce MFA for users who have access to Microsoft Sentinel to enhance security.
- Use Groups: Whenever possible, assign roles to groups rather than individual users. This simplifies role management and ensures consistent permissions across team members.
Example of Role Assignment Scenario
Consider a scenario where you have a security team with various members, each requiring different access levels:
- Analysts: Need to view incidents and dashboards but should not modify configurations. They would be assigned the Sentinel Reader role.
- Incident Responders: Require the ability to manage incidents; they would be given the Sentinel Responder role.
- Engineers: Need to set up automation rules and playbooks, so they would receive the Sentinel Automation Contributor role.
- Security Managers: Need to oversee everything and possibly make configuration changes; they would have the Sentinel Contributor role.
By understanding and leveraging Microsoft Sentinel roles effectively, organizations can ensure that their security operations team works efficiently and within the defined scope of their responsibilities, greatly enhancing the organization’s security posture.
Practice Test with Explanation
True/False: You need to assign the “Security Administrator” role in Azure AD to configure Microsoft Sentinel.
- Answer: False
Explanation: The “Security Administrator” role is related to Azure AD security, but to configure Microsoft Sentinel, you would typically need to have the “Contributor” or a specific “Sentinel Contributor” role at the subscription or resource group level where Sentinel is deployed.
True/False: The “Sentinel Contributor” role allows a user to view and investigate alerts in Microsoft Sentinel.
- Answer: True
Explanation: The “Sentinel Contributor” role has permissions that allow users to manage all Microsoft Sentinel related resources, including viewing and investigating alerts.
Which role is required to manage Microsoft Sentinel data connectors?
- A) Sentinel Reader
- B) Sentinel Contributor
- C) Global Administrator
- D) Security Reader
- Answer: B) Sentinel Contributor
Explanation: The Sentinel Contributor role is required to manage data connectors as it allows the management of Microsoft Sentinel resources.
True/False: A user with the “Sentinel Responder” role can dismiss incidents.
- Answer: True
Explanation: The “Sentinel Responder” role has permissions to perform actions on incidents, including dismissing them.
Which role should you assign to a user who only needs to run queries and view results in Microsoft Sentinel workbooks?
- A) Sentinel Responder
- B) Sentinel Contributor
- C) Sentinel Reader
- D) Security Operator
- Answer: C) Sentinel Reader
Explanation: The “Sentinel Reader” role is sufficient for a user to run queries and view the results in Microsoft Sentinel workbooks without making any changes to the configuration.
True/False: The “Security Reader” role in Azure AD is all you need to fully manage Microsoft Sentinel incidents.
- Answer: False
Explanation: While the “Security Reader” can view security data and alerts, they cannot manage incidents in Microsoft Sentinel. An appropriate Sentinel role such as “Sentinel Contributor” or “Sentinel Responder” is required to manage incidents.
What is the minimum role needed to delete an incident in Microsoft Sentinel?
- A) Sentinel Contributor
- B) Security Administrator
- C) Global Administrator
- D) Sentinel Responder
- Answer: A) Sentinel Contributor
Explanation: A user with the “Sentinel Contributor” role has adequate permissions to delete incidents in Microsoft Sentinel. The “Sentinel Responder” role does not have permission to delete incidents.
True/False: Users with the “Global Reader” Azure AD role can create and manage playbooks in Microsoft Sentinel.
- Answer: False
Explanation: The “Global Reader” role in Azure AD has read-only privileges. To create and manage playbooks in Microsoft Sentinel, the user needs to have a role that allows writing permissions, such as the “Sentinel Contributor”.
To whom should you assign the Microsoft Sentinel role that enables viewing and managing threat intelligence indicators?
- A) Sentinel Contributor
- B) Security Operator
- C) Global Administrator
- D) Sentinel Reader
- Answer: A) Sentinel Contributor
Explanation: The “Sentinel Contributor” role would allow a user to view and manage threat intelligence indicators in Microsoft Sentinel.
Who can use Microsoft Sentinel to respond to incidents by bookmarking events and adding comments to incidents?
- A) Sentinel Reader
- B) Security Administrator
- C) Sentinel Responder
- D) Global Administrator
- Answer: C) Sentinel Responder
Explanation: The “Sentinel Responder” role has the permissions required to bookmark events and add comments to incidents in the response to them within Microsoft Sentinel.
True/False: Users with the “Sentinel Automation Contributor” role can only read Microsoft Sentinel data and cannot modify any resources.
- Answer: False
Explanation: The “Sentinel Automation Contributor” role allows users to create and modify automations and playbooks in addition to reading data, which means they can modify some resources within the context of automation in Microsoft Sentinel.
Which of the following permissions are included in the “Sentinel Reader” role? (Select two)
- A) Create and manage workbooks
- B) Modify incident properties
- C) View Microsoft Sentinel data
- D) Execute playbook actions
- E) View Microsoft Sentinel incidents
- Answer: C) View Microsoft Sentinel data, E) View Microsoft Sentinel incidents
Explanation: The “Sentinel Reader” role includes permissions to view Microsoft Sentinel data and incidents, but it does not allow creating and managing workbooks, modifying incident properties, or executing playbook actions.
