When it comes to managing external data connectivity in Power BI, the following guidelines must be observed:
Utilize Power BI Gateway: For on-premises data sources, the Power BI On-Premises Data Gateway should be utilized to gain access to Power BI. Make sure the gateway is set to use HTTPS to encrypt the communication between the Power BI Service and the data source. The network gateway should be placed in a zone where external interference is minimized.
Safety and Security: Never use an unencrypted connection. Instead, it is recommended to connect using HTTPS and SSL or a secure sockets layer to protect the data. Ensure that the data is secured when it is being moved or even when it is not being moved. Instead of hard-coding passwords into queries, rely on OAuth2 or other secure means of authentication.
Safely Handle Credentials: Securely save all credentials by making use of the credential management Power BI service offers. For Azure-based data sources, try to refrain from using personal accounts as much as possible. Wearing out sensitive information by regularly changing passwords serves as an added advantage.
Restrict Access:
- Only provide access to the data source or Power BI workspace to those who are part of the team.
- In Power BI, use Role-Level Security (RLS) to enhance security based on user roles assigned.
- For even better security, remember to use Multi-Factor Authentication (MFA).
Monitor and Audit: Perform audits within Power BI to check how data and users are accessed. Systematic examination of records should be performed to eliminate or detect any security risks.
Keep Systems Updated: Apply all protective systems, such as gateways, Power BI, and interconnected systems, at the rate of their patching on a regular basis to fix any existing threats.
Following these measures will help you ensure that the external data connection is secure and that the risks are greatly minimized in the Power BI environment.
