Best Practices for Securing Microsoft Power Platform
Best Practices for Securing Microsoft Power Platform
Section titled “Best Practices for Securing Microsoft Power Platform”The Microsoft Power Platform—which includes Power BI, Power Apps, Power Automate, and Power Virtual Agents—allows organizations to create custom applications, automate workflows, and analyze data. However, as the platform integrates deeply with various systems like Microsoft 365, SharePoint, and Dynamics 365, it introduces potential security risks. Properly securing the Power Platform is essential to ensure data protection, maintain compliance, and prevent unauthorized access.
In this guide, we will cover best practices for securing the Power Platform, common pitfalls to avoid, and the importance of using Griffin31 to monitor for misconfigurations and alert for security changes. Additionally, we will address key security recommendations related to sharing settings, permissions, email rules, and custom connectors.
Why Securing Microsoft Power Platform is Critical
Section titled “Why Securing Microsoft Power Platform is Critical”The Power Platform enables users to quickly build apps and workflows, often without the oversight of professional developers. While this promotes innovation, it also introduces potential security risks, such as incorrect permissions or data exposure. Given the deep integration with critical business systems, a vulnerability in the Power Platform could expose sensitive data or disrupt operations.
Best Practices for Securing Microsoft Power Platform
Section titled “Best Practices for Securing Microsoft Power Platform”1. Implement Role-Based Access Control (RBAC)
Section titled “1. Implement Role-Based Access Control (RBAC)”RBAC helps ensure that users only have access to the resources they need. Power Platform uses RBAC to manage access to apps, flows, and connectors.
Best Practice: Apply the Principle of Least Privilege to ensure users have only the permissions necessary for their roles. Regularly review role assignments and ensure that access is revoked for users who no longer need it.
2. Enforce Multi-Factor Authentication (MFA)
Section titled “2. Enforce Multi-Factor Authentication (MFA)”Requiring Multi-Factor Authentication (MFA) for accessing Power Platform resources adds an extra layer of security, especially for privileged users.
Best Practice: Configure MFA for accessing all Power Platform components, including Power Apps, Power Automate flows, and Power BI. Ensure MFA is applied through Conditional Access policies.
3. Control Data Connectors
Section titled “3. Control Data Connectors”Data connectors link Power Platform apps and workflows to external services. Misconfigured or over-permissioned connectors can lead to data exposure or leakage.
Best Practice: Restrict the use of connectors to trusted services and users. Implement Data Loss Prevention (DLP) policies to prevent sensitive data from being transferred to untrusted services.
4. Leverage Data Loss Prevention (DLP) Policies
Section titled “4. Leverage Data Loss Prevention (DLP) Policies”DLP policies are essential for controlling data flow between Power Platform components and external services.
Best Practice: Enforce DLP policies that prevent data from being shared between your internal systems and personal or untrusted services like Dropbox or Gmail. Regularly review and update your DLP rules to adapt to new connectors or services.
5. Limit Sharing and Permissions in PowerApps
Section titled “5. Limit Sharing and Permissions in PowerApps”Sharing PowerApps with broad groups can lead to unauthorized access or misuse of applications.
Best Practice: Avoid configuring PowerApps to be shared with “Everyone.” Instead, limit app sharing to specific user groups who require access. Regularly review permissions to ensure that they are correctly aligned with user roles.
6. Set Permissions for Power Automate Flows
Section titled “6. Set Permissions for Power Automate Flows”Power Automate flows often have access to critical data, and misconfigured flows can result in unauthorized access.
Best Practice: Limit permissions for Power Automate flows based on user roles. Ensure that only authorized users can create, modify, or run specific flows.
7. Configure Rules for Outgoing Emails
Section titled “7. Configure Rules for Outgoing Emails”Without proper rules, Power Platform applications and workflows could send sensitive data via email to unauthorized recipients.
Best Practice: Configure rules within the platform to block or restrict outgoing emails containing sensitive data. Set up alerts for any suspicious email activity generated by Power Platform workflows or apps.
8. Limit Custom Connectors
Section titled “8. Limit Custom Connectors”Custom connectors allow Power Platform apps and flows to connect to external services. If not properly controlled, they can introduce security risks.
Best Practice: Restrict the use of custom connectors to trusted services. Review and limit who can create and deploy custom connectors, and apply DLP policies to prevent data from flowing to unverified services.
9. Separate Development, Testing, and Production Environments
Section titled “9. Separate Development, Testing, and Production Environments”Using environments properly helps you segregate development, testing, and production data, reducing the risk of exposure.
Best Practice: Use separate environments for development, testing, and production. Assign environment-specific administrators and apply environment-specific security settings and policies.
10. Enable Logging and Monitor Anomalies
Section titled “10. Enable Logging and Monitor Anomalies”The Power Platform Admin Center provides detailed logs of user activity, app usage, and flow runs. Monitoring these logs helps detect suspicious activity.
Best Practice: Enable activity logging for all Power Platform environments. Set up alerts for unusual activity, such as abnormal app usage or flow executions, and investigate anomalies promptly.
Using Griffin31 to Monitor and Secure Microsoft Power Platform
Section titled “Using Griffin31 to Monitor and Secure Microsoft Power Platform”While Microsoft offers robust tools for securing Power Platform, continuous monitoring for misconfigurations is critical to maintaining long-term security. This is where Griffin31 comes in.
How Griffin31 Enhances Power Platform Security

Common Pitfalls to Avoid When Securing Power Platform
Section titled “Common Pitfalls to Avoid When Securing Power Platform”Even with the best security measures in place, organizations can still fall into common traps that compromise their Power Platform security. Here are the top pitfalls to avoid:
1. Over-Permissive Sharing in PowerApps
Section titled “1. Over-Permissive Sharing in PowerApps”Pitfall: Allowing PowerApps to be shared with “Everyone” can result in data exposure.
Solution: Restrict sharing to specific user groups, review sharing permissions regularly, and disable the “Everyone” sharing option where possible.
2. Excessive Permissions for Power Automate Flows
Section titled “2. Excessive Permissions for Power Automate Flows”Pitfall: Over-permissioned flows can lead to unauthorized data access.
Solution: Limit permissions for flows, ensuring that only necessary data and actions are accessible, based on user roles.
3. Lack of Email Rules for Outgoing Communications
Section titled “3. Lack of Email Rules for Outgoing Communications”Pitfall: Workflows sending unmonitored emails could expose sensitive data.
Solution: Configure and enforce email rules to block or review outgoing communications from Power Platform apps and flows.
4. Unrestricted Use of Custom Connectors
Section titled “4. Unrestricted Use of Custom Connectors”Pitfall: Unrestricted custom connectors can lead to unauthorized data transfers.
Solution: Limit custom connector usage, enforce DLP policies, and regularly audit connectors.
5. Not Monitoring Environment-Specific Security
Section titled “5. Not Monitoring Environment-Specific Security”Pitfall: Insufficient environment segregation increases the risk of data exposure.
Solution: Use separate environments for development, testing, and production with clear access controls and security policies for each.
