Operational Security in Power Platform
Operational security on Microsoft Power Platform involves implementing security measures to safeguard the platform’s operational processes, mainly focusing on access control, data integrity, and system reliability. Depending on the deployed application’s complexity, various security issues may arise during testing. Below, we will discuss the common operational security issues and how you can troubleshoot them.
Common Operational Security Issues & How to Troubleshoot them
-
Access Control issues
The most common security issue you might encounter during testing is unauthorized access, which could be due to misconfigured roles and permissions.
Troubleshoot: Verify user roles and permissions. Microsoft Power Platform employs Role-Based Access Control (RBAC) so you can grant users access only to the resources they need. Use the Power Platform admin center to review and edit user roles and permissions as needed.
Here is a sample script for ascertaining the roles assigned to a user.
Add-PowerAppsAccount -Username 'username' -Password 'password'
$userRoles = Get-AdminPowerAppRoleAssignment -UserId 'userId' -
Data Integrity issues
It entails issues that compromise the accuracy, consistency, and reliability of data. Data integrity issues may arise from system crashes, data leaks, or the transmission of incomplete or incorrect data.
Troubleshoot: Regular backups and data validation can help maintain data integrity. Power Platform provides versioning and data loss prevention (DLP) policies that allow you to safeguard and control how data is shared across your apps. Make sure these are properly configured and employed.

System Availability issues
If your apps and flows are not reliably available, this can be a significant issue that could incur data loss and hamper business processes.
Troubleshoot: Regular system monitoring is the best way to ensure system availability. Use tools such as Power Apps Diagnostics and Power Automate Analytics to monitor app performance and act on any irregularities.
Furthermore, Power Platform provides environment variables that you can use to customize error messages and handle exceptions more effectively. Here is an example of how you can use them in your code:
catch (NullReferenceException e)
{
string customErrorMessage = Environment.GetEnvironmentVariable("CustomErrorMessage");
log.LogError(customErrorMessage, e);
throw new Exception(customErrorMessage, e);
} -
Poor Code Quality
Inefficient or poorly written code can lead to security vulnerabilities, performance issues, and maintenance challenges.
Troubleshoot: Use code review processes and static code analysis tools to identify and address code quality issues. For example, Power Apps Checker is a service for validating app quality that checks your app against a set of rules and provides guidance on how to improve app performance and maintainability.
Keep in mind; the above troubleshooting methods should be employed not only when issues arise but as part of your regular application or process lifecycle. This preventative measure can ensure smoother running applications and significantly decrease the risk of operational security issues in the long run.
This quick guide provides you with an overview of some operational security issues you may encounter during testing in your PL-400 Microsoft Power Platform Developer role and, more importantly, how to troubleshoot these issues. However, remember that each situation might be unique, so leveraging Microsoft’s robust documentation and community forums can always provide further assistance.

Interview Questions
What is the fault-tolerant behavior of cloud services in Microsoft Power Platform?
In Microsoft Power Platform, fault tolerance refers to the ability of the system to continue operating even if there are one or more component failures. Cloud services can be grouped into fault domains and update domains to assure continuity of service during platform and network maintenance.
What is SQL injection and how to prevent it in Microsoft Power Platform?
SQL injection is a code injection technique used to attack data-driven applications. In Microsoft Power Platform, developers can help prevent it by using parameterized queries, which can assure that input values are treated as literal data, not executable code.
How to fix the “winrm cannot process the request” error message in Power Platform?
This error message usually means that your machine cannot establish a connection with the remote machine via WinRM. Possible solutions include checking the network connections, verifying that the remote machine is running, and ensuring that WinRM is installed and running on the remote computer.
What can you do if you encounter an error in your Flow operation in Power Automate?
If you encounter an error in your Flow, you can use the built-in error handling in Power Automate, which allows you to manage your flows and diagnose any issues. You can also use the “Configure run after” setting to specify actions that should run after other actions have failed, have been skipped, or are successful.
What common operational security issue can occur when working with Power Apps Canvas Apps?
A common issue is insufficient validation of input fields. This can be mitigated by implementing custom validation on input fields using OnChange property or by implementing data entity level business rules in the backend to ensure data consistency and security.
What is the purpose of the Security role in Dynamics 365 within Power Platform?
The Security Role in Dynamics 365 provides user access management, allowing you to control who has access to which data and functionalities in your applications.
How can you mitigate the security risk of Data leakage in Power BI?
Data can be protected and controlled by implementing Row-level security (RLS) that restricts data access at the row level based on filters. RLS helps in preventing data leakage and ensuring only authorized users can access sensitive data.
What component of Power Platform should you utilize to track the operational security issues after running tests?
Generically, you can use Power Platform’s built-in analytics features, such as Power Apps Monitor, to track errors and performance issues during and after testing.
How can you ensure the secure transfer of data within Power Automate?
Data within Power Automate is secured by default, as the platform utilizes Azure’s built-in suite of security tools like Advanced Threat Protection and Automatic Encrypted data transfers. Nevertheless, for sensitive data, users can implement more robust security measures like data loss prevention (DLP) policies.
How can you maintain operational security while sharing Canvas Apps with others?
To maintain security while sharing Canvas Apps, it is recommended that you use “Share” within the app settings instead of sharing your login details. It’s also crucial to assign roles to team members to control what they can see and do within the app.
What is the purpose of Service trust portal in Microsoft Power Platform?
The Service Trust Portal provides a variety of content, tools and other resources about Microsoft security, privacy, and compliance practices. It helps in understanding the measures and controls implemented in Microsoft cloud services to maintain security and compliance.
What security measures need to be implemented when using Power Apps in combination with other data sources like SharePoint?
When using Power Apps with SharePoint, a necessary measure is to ensure that the SharePoint permissions are correctly configured. Power Apps respect the data source’s permissions, so if a user does not have access to view or edit the SharePoint List, they will not be able to view or edit it in the Power App.
What is IP restriction in Power Platform and how can it be used for operational security?
IP restriction is a feature in Power Platform where admins can specify a range of IP addresses from which their resources can be accessed. This can help increase operational security by restricting resource access to known and trusted IP addresses.
How does Microsoft Power Platform guarantee data isolation?
Microsoft Power Platform provides data isolation by storing each tenant’s data separately, and also by ensuring that all data transferred between the customer and Microsoft data centers is encrypted.
What is Defense in Depth strategy for operational security in Microsoft Power Platform?
Defense in depth is an approach in Power Platform where multiple layers of security controls (defense) are placed throughout an information technology (IT) system. It mitigates risk of one component failing, because other mechanisms will continue to provide security.
