Application Security in Business Central

This section helps you understand and improve the security of your Business Central application regardless of where it's hosted. In the sections listed below, you'll find guidance and recommended practices related to authentication, authorization, and auditing, in addition to data encryption and secure development practices that can be applied to any Business Central environment.

Business Central uses a layered approach to application security, as outlined in the following diagram.

Security overview.


Before users can sign in to the Business Central application, they must be authenticated as a valid user in the system. Business Central (on-premises) supports several authentication methods, such as Windows and Azure Active Directory (Azure AD). Business Central online deployments use Azure AD only. For more information, see the following articles:

Authentication and Credential Types

Multifactor Authentication

The authentication method configured for Business Central Server is also used to access web services. For more information, see Web Services Authentication.


After a user is authenticated, authorization determines which areas the user can access, such as the pages and reports they can open and the permissions they have on associated data. For more information, see the following articles:

Business Central includes several auditing features that help you track information about who is signing in, what their permissions are, what data they've changed, and more. For more information, see the following articles:

Data Classification

Data encryption

You can encrypt data on the Business Central server by generating new encryption keys—or importing existing ones—that you enable on the Business Central server instance that connects to the database. For more information, see Encrypting Data in Dynamics 365 Business Central.

Security development lifecycle

The Microsoft Security Development Lifecycle (SDL) is a software development process that helps developers build more secure software and address security compliance requirements while reducing development cost. For more information, see Security Development Lifecycle.
