Understanding the power and potential of Microsoft Power Platform, a powerful toolset for developers, requires a thorough comprehension of its security capabilities. This includes aspects such as data loss prevention (DLP) policies, security roles, teams, business units and record (row) sharing. In this post, we will delve deeper into each of these areas, providing relevant examples where necessary, in order to prepare you for your PL-400 Microsoft Power Platform Developer examination.
Data Loss Prevention (DLP) Policies
DLP is a data management strategy mainly used to prevent unintentional data leakage or access. In the Microsoft Power Platform, DLP policies serve to control how data is shared between Microsoft and non-Microsoft applications and services. Data groups are categorized as either “Business” or “Non-Business”, and you can design your DLP policies by deciding which categories of data can interact with each other.
Microsoft describes three types of DLP policies:
- Tenant-wide: These are default policies that apply to all environments in the tenant. They prevent the sharing of business data with non-business apps.
- Environment-specific: These policies only apply to an individual environment.
- Policy of ‘no other policy’: If you choose not to implement a DLP policy, a default policy is created and used.
Security Roles
Power Platform employs role-based security, which means that access to resources is dependent upon user roles. Roles in Power Platform encapsulate a set of privileges and permissions that determine what users can see (e.g., data) and do (e.g., operations).
There are two types of security roles: pre-defined system roles and customizable business roles. System roles are tailored for various functions, such as system administration and customer service. In contrast, business roles are custom roles that match the specific needs of your organization.
Teams
In Power Platform, teams are groups of users that share and collaborate on business processes, records, and data. Teams help manage data and user access in a complex organizational hierarchy. They can be used to simplify record sharing and boost collaboration.
Teams can be owner teams, which own records and have security roles, or access teams, which do not own records but have sharing privileges.
Business Units
Business units in Power Platform provide a mechanism to segregate data and control access rights within your organization. They are hierarchical, meaning a parent business unit can have one or more child units, allowing complex data isolation.
Cases where you might use business units include when you need to:
- Create different views or dashboards based on business units
- Control access to records
Record (Row) Sharing
Microsoft Power Platform employs a few sharing models to organize how data is shared among users throughout your organization:
- Basic sharing: A user or team can grant another user or team access to a record.
- Manual sharing: A user with ‘Share’ privilege can share the record directly.
- Inheritance from Teams or Business Units: Users within the same team or business unit can access shared records.
These features provide granular record-level security by determining access rights at the record level.
Understanding these security capabilities of the Microsoft Power Platform is critical to making the most of its tools while protecting your organization’s sensitive information. By carefully configuring DLP policies, security roles, teams, business units, and record sharing, you can create a secure and efficient environment for your team or business.
Take these concepts along with you in the PL-400 Microsoft Power Platform Developer examination, where they will help enhance your knowledge of the depth and breadth of Power Platform’s security functionalities.

Interview Questions
What is Data Loss Prevention (DLP) in Microsoft Power Platform?
Data Loss Prevention (DLP) in Microsoft Power Platform helps prevent accidental data leakage by enforcing rules and policies on how data can be shared between different services within the platform.
Can you briefly explain the function of security roles in Microsoft Power Platform?
Security roles in Microsoft Power Platform help to manage user permissions. They define what users can do with data and what areas of the system they can access.
What are teams in the context of Microsoft Power Platform?
Teams in the Microsoft Power Platform are groups of users who can be given specific access to data and functionalities. They can be used to simplify certain tasks like sharing work or managing permissions.
What are business units within the security model of the Microsoft Power Platform?
Business units are a way to group and manage users, data, and security roles in Microsoft Power Platform. They can be used to mirror the structure of a business, allowing for the segregation and management of data and operations.
How does row-level sharing work in Microsoft Power Platform?
Row-level sharing in Microsoft Power Platform allows specific records to be shared with individual users or teams. This is a way to provide access to data on a row-by-row basis, rather than based on security roles or teams.
What is the purpose of the security model in Microsoft Power Platform?
The security model in Microsoft Power Platform is designed to protect data integrity and privacy by controlling access to data. This is achieved through the configuration of security roles, business units, teams, and data policies.
Can you assign multiple security roles to a single user in Microsoft Power Platform?
Yes, it’s possible to assign multiple security roles to a user in Microsoft Power Platform. The permissions of each role sum up to determine the user’s total permissions.
How does Microsoft Power Platform ensure data security?
Microsoft Power Platform ensures data security through features like Data Loss Prevention (DLP) policies, security roles, user and team management, business units, and row sharing functionalities.
How do Data Loss Prevention (DLP) policies affect the use of connectors in Power Platform?
DLP policies in Power Platform determine which connectors can share data with each other. They are used to classify connectors as either Business or Non-Business, and to prevent data leakage between these connector groups.
What is the function of a Business Unit in Microsoft Power Platform?
A Business Unit in Microsoft Power Platform is a logical grouping of users who are subject to common access rights for data records. Users within a specific business unit only have access to the records owned by that business unit, effectively segregating data within the organization.
Can you cite an example of how to use Teams in Microsoft Power Platform?
Teams in Microsoft Power Platform can be used to manage access to records. For instance, if a sales team needs access to the same sales records, these records can be owned by a team rather than an individual user. This way, all users in the team have access to these records.
How does role-based security work in Microsoft Power Platform?
Role-based security in Microsoft Power Platform works by associating access levels and privileges with each security role. Users assigned to that role inherit these access levels and privileges, which define what they can do with various types of data within the system.
Can guest users be assigned a Power Platform security role?
Yes, a Power Platform security role can be assigned to a guest user. Once a user is invited as a guest in Azure Active Directory (Azure AD), the guest user can be assigned Power Platform security roles.
Can teams in Microsoft Power Platform have security roles?
Yes, teams within Microsoft Power Platform can have security roles assigned to them. Any user who is part of the team inherits the security roles assigned to the team.
Can a user belong to multiple business units in Microsoft Power Platform?
No, a user in Microsoft Power Platform cannot belong to multiple business units. However, a user can access data from other business units if they have been given the appropriate access rights.
