What is a Privileged Endpoint?
The Privileged Endpoint is a special, secured environment that is hosted on a dedicated virtual machine within the Azure Stack Hub infrastructure. It is used for performing internal operations, such as troubleshooting, repairing system states, and executing emergency actions which require higher levels of permission.
Preparing to Connect to the PEP
Before connecting to the Privileged Endpoint, you must meet certain prerequisites:
- Access Control: Only authorized users or accounts with sufficient privileges can access PEP. Ensure you have the credentials with the appropriate role-based access control (RBAC) permissions.
- Secure Workstation: The workstation from which you will connect to the PEP should be secured and meet your organization’s security standards.
- Network Configuration: Proper network settings should be in place to allow secure connectivity between your workstation and the Azure Stack Hub.
Connecting to the Privileged Endpoint
To establish a connection to the Privileged Endpoint, you can use PowerShell Direct or a Remote Desktop Connection. Here’s a typical process:
- Enable Just In Time (JIT) Access: For security, PEP is usually accessible only for a limited time window. You may need to enable JIT access if it’s enforced in your environment.
- Remote Desktop or PowerShell Direct: Establish a Remote Desktop session or use PowerShell Direct to connect to PEP from a privileged management workstation.
- Enter Credentials: You will be prompted to enter credentials that have the necessary rights to access PEP.
- Execute Commands: Once connected, you can run specific cmdlets or scripts that are built for infrastructure maintenance and troubleshooting.
Examples of using PEP
Here are some common uses of PEP in Azure Stack Hub:
- Repairing a faulty role instance: If an infrastructure role instance is in a failed state, you can connect to the PEP and run the
Repair-AzsInfrastructureRoleInstancecmdlet to attempt a repair. - Collecting diagnostic logs: To troubleshoot issues, you can execute the
Get-AzsLogcmdlet to collect logs and diagnostic information from Azure Stack Hub components. - Restoring user permissions: If a cloud operator’s permissions are mistakenly removed, PEP can be used to run
Set-AzsUserSubscriptionto restore them.
Security Considerations
When working with the PEP, keep the following security practices in mind:
- Limited Access: Limit access to PEP to only essential personnel who are trained to use it.
- Audit Logging: All activities carried out on the PEP are logged. Regularly audit these logs to detect and investigate any unauthorized access or actions.
- Session Management: Keep PEP session duration as brief as possible and only use it for intended purposes to minimize the potential exposure of the privileged environment.
- Credential Management: Use strong authentication and credential management practices. Rotate credentials and use multi-factor authentication where possible.
Conclusion
Connecting to a Privileged Endpoint in Azure Stack Hub is a powerful but sensitive operation that should be handled with the utmost care. Understanding how to securely connect to and use the PEP is a crucial skill for administering, troubleshooting, and maintaining an Azure Stack Hub environment, as covered in the AZ-600 exam.
Remember that while PEP provides administrators with great power to manage and rectify system issues, its usage should be accompanied by strict adherence to operational and security best practices to ensure the integrity and stability of the entire hybrid cloud environment.
Practice Test with Explanation
True or False: To connect to a privileged endpoint, you must first establish a remote PowerShell session with an Azure Stack Hub.
- A) True

True or False: You need to be on the Azure Stack Hub host to access the privileged endpoint.
- A) True
- B) False
Answer: B) False
Explanation: You can access the privileged endpoint remotely, via a remote PowerShell session and do not need to be on the Azure Stack Hub host.
Which of the following ports must be opened to connect to the privileged endpoint from a remote location?
- A) 80
- B) 443
- C) 5985
- D) 5986
Answer: C) 5985
Explanation: Port 5985 is used for remote PowerShell sessions which is necessary to connect to the privileged endpoint over HTTP.
True or False: You can use any PowerShell version to connect to the privileged endpoint in Azure Stack Hub.
- A) True
- B) False
Answer: B) False
Explanation: Azure Stack Hub requires a specific version of PowerShell; using incompatible versions might cause connectivity issues.
When connecting to the privileged endpoint, which module should be imported to facilitate the creation of the PEP session in Azure Stack Hub?
- A) AzureRM
- B) Az
- C) AzureStack
- D) PEP
Answer: C) AzureStack
Explanation: The AzureStack module contains the necessary cmdlets to connect to Azure Stack Hub’s privileged endpoint.
True or False: You can connect to the Azure Stack Hub privileged endpoint using Azure CLI.
- A) True
- B) False
Answer: B) False
Explanation: The privileged endpoint requires a PowerShell session, hence connecting with Azure CLI is not supported.
What is the recommended practice to secure the privileged endpoint?
- A) Change the default port for the remote PowerShell session
- B) Use Just Enough Administration (JEA)
- C) Disable firewall rules for the endpoint
- D) Use a common administrator account
Answer: B) Use Just Enough Administration (JEA)
Explanation: Just Enough Administration (JEA) helps limit the commands that can be run within the privileged endpoint, enhancing security.
True or False: The Privileged Access Workstation (PAW) can be used for securing the connection to the privileged endpoint.
- A) True
- B) False
Answer: A) True
Explanation: PAW is a hardened workstation designed for sensitive tasks such as connecting to a privileged endpoint, and it ensures a secure environment for administrative tasks.
