In the contemporary data-centric world, organisations use BI Power to get insights, conduct data-led decisions, and gain an edge in the competition. However, with such powerful abilities comes a great responsibility which is especially the case when it comes to keeping sensitive information secure and ensuring the proper functioning of Power BI.
Data visualisation with dashboards and reports can make sensitive information very attractive to cyber attackers, which is why protecting your Power BI instance is a must. The IBM’s 2023 Cost of a Data Breach Report reveals that the average cost of a global cyber-attack has reached $4.45 million. But don’t worry! This all-inclusive guide will teach you key strategies and the best practices to build a solid security barrier around your Power BI data, so you can use your insights without the constant worry of security breaches.
Place of security in PowerBI’s architecture
Microsoft Power BI is a powerful software-as-a-service (SaaS) tool that operates on the secure and reliable Azure cloud platform. To understand how Power BI works behind the scenes, it’s helpful to look at its architecture, which is built around two main clusters: the Web Front End (WFE) cluster and the Back-End cluster. These clusters work together to ensure that your Power BI experience is smooth and efficient.
The flow goes as the following:
- Web Front End (WFE) Cluster: The place where it all begins. Upon signing into Power BI, the WFE cluster takes care of the initial connection and authentication process. It is like the welcome desk of the Power BI service, verifying your identity before granting you access.
- Back-End Cluster: Back-End Cluster is in charge once you are securely authenticated. This one is the one that handles the tasks processing and user queries for Power BI, and it is the one that transmits data. You could say it’s a set of gears that ensures that the overall system operates fine without any visible actions.
Power BI has Azure Active Directory (AAD) under which it allows for the seamless management and storage of user identities safely. These identities are stored on Azure Blob storage which is a highly reliable and scalable. When it comes to your data management, Power BI utilises Azure SQL Database which is secured with encryption at rest for your data privacy. You still have the option to bring your own encryption key for even more control over your data security.
To achieve a high level of performance, Power BI directly routes the traffic through Azure Traffic Manager (ATM). It points out to the WFE knocks fast and secures the authentication and steady content delivery. Power BI uses Azure Content Delivery Network (CDN) for the delivery of images and files which enables fast and effective delivery of the content based on the geographical location of the users.
The Importance of Security in Power BI
Before we dive into specific security measures, it is important first to realise the critical security purpose behind keeping your Power BI platform safe and sound. Let’s take a look at the main reasons:
Sensitive Data needs to be Protected:
Power BI frequently contains critical information such as financial data and customer details as well as valuable intellectual property. If this data is not properly secured, it could be exposed to breaches or leaks, resulting in legal and financial repercussions. Let’s say the disaster happens if non-confidential financial figures or sensitive customer information land in the wrong hands. Therefore, data safeguarding is the utmost concern.
Maintaining Compliance:
Across various industries, there are laws e.g. GDPR, HIPAA, or SOX that regulate how data should be stored securely. Compliance with these rules is not just the process of checking your list of requirements, but it is the basis of forming and keeping trust with your customers and stakeholders. By ensuring your Power BI environment meets these standards, you’re not only avoiding legal trouble but also showing your commitment to data protection.
Preventing Unauthorised Access:
Unauthorised access to Power BI reports and dashboards can have serious consequences. It might result in the data’s being used incorrectly, the insights’ being distorted, or even the business operations’ being sabotaged. Keeping tight control over who can access and interact with your Power BI environment helps prevent these risks and ensures that your data remains accurate and secure.
Security Components That Power BI Offers
Let’s check out the most important security features that Power BI offers to keep your data safe:
- Tenant-Level Security: Controls who can access your organisation and authenticates and authorises users to ensure that only the right people can get in.
- Dataset and Report-Level Security: You can control the access to specific datasets, reports, and dashboards, so only authorised users can view or interact with sensitive information.
- Row-Level Security (RLS): Only authorised people have access to specific rows of a dataset depending on their roles or identities. This way, users will only see the data that is relevant to them.
- Data Encryption: Both data in transit and data at rest are encrypted, so your information is secure whether it’s moving between servers or stored inside Power BI.
Best Practices to Ensure Power BI Security
Securing your Power BI environment involves a variety of strategies to protect sensitive data. Here’s how you can make the most of Power BI’s security features:
- Turn on Row-Level Security (RLS):
RLS is a data security feature that allows data to be visible only to users whose roles are relevant to the information. By designing the roles and utilising DAX expressions to implement data filters, you can decide which data each user can access. This method is in accordance with the least privilege principle and therefore ensures data confidentiality.
- Use Object-Level Security (OLS):
OLS provides an extra layer of data protection by not allowing access to sensitive data, but only particular tables and columns from your reports or datasets. The limitation of access to sensitive information is achieved by role definition and permission allocation. This is done in such a way that only those who are properly authorised can access this sensitive information. Thus, the critical data is protected, and the overall security is enhanced.
- Integrate Azure Active Directory (AD):
Combining Azure AD and Power BI allows for advanced security features such as Single Sign-On (SSO), Multi-Factor Authentication (MFA), and Role-Based Access Control (RBAC). These instruments confirm the user, limit the access, and eliminate the possibilities of non-allowed access.
- Implement Sensitivity Labels:
Sensitivity labels are used to manage the processing of sensitive data by classifying it according to sensitivity level. The organisation can then ensure that its data governance policies are enforced, and sensitive information is safeguarded both inside and outside the organisation.
- Boost Workspace Security:
The Power BI workspace restricts access to the datasets, reports, and dashboards based on the roles of the users such as administrator, member, contributor, and viewer. Good role distribution is the way to go when it comes to responsibility segregation and minimising the chance of data unauthorised alters and exposure.
- Conduct Frequent Audits:
Routine auditing of Power BI operations, including data access and report sharing, allows to detect compliance violations and security breaches. Analysing audit logs lets you to detect inappropriate behaviour and take necessary actions in a timely manner.
- Control Guest Access:
Guest access management is possible with Azure AD B2B collaboration in which the external users shall be able only to see the information permitted to them, hence preserving the data privacy and allowing the secure data sharing clients and partners.
- Ensure Data and Service Integrity:
Take advantage of Power BI’s secure sharing settings and Azure’s encryption features to encrypt data sent and received via the network. Sharing configurations and dataflows that are properly set up guarantee data integrity and prevent the information from being sent to the wrong destination.
- Monitor the Data Gateway:
Data gateways enable Power BI to connect to on-premises data sources. Protect these gateways by ensuring they are fully updated, restricting administrative access, and safeguarding data transfers from eavesdroppers.
- Adopt Data Classification and Retention Policies:
Power BI has tools for data classification and retention. Retaining information only as long as it is necessary is a big help in improving data management and minimising the risk of breaches.
- Educate Users:
It is necessary to train the users on security best practices such as recognising phishing attempts and using strong passwords. Besides that, the company will provide defence against security Incidents because of users getting educated frequently.
- Conduct Security Assessments:
Consistently schedule security beatings, which include penetration testing and vulnerability scanning, to discover, fix and properly prevent any security weaknesses. The assessments reveal that your security measures are up to date with the constantly changing cyber threats.
- Utilise Built-In Data Protection:
Power BI has embedded data protection features like Information Rights Management (IRM) and Data Loss Prevention (DLP). IRM prohibits the access to reports and datasets and DLP rules ensure that the data sharing is done only by the authorised personnel which improves data security.
