Security in Business Central

A business solution must have a built-in security system that helps protect your database, and the information that it contains, from unauthorized access. It must also allow you to specify what authenticated users are allowed to do in the database, such as what data they can read and modify. The following articles will help you understand and improve the security of Business Central.


Starting March, 2020, Business Central only supports Transport Layer Security (TLS) version 1.2 or later. This applies to Business Central 2019 release wave 2 online and on-premises (version 15.x). Upgrade to Business Central 2019 release wave 2 or later to remove support for earlier versions of TLS. If your solution or an add-on uses TLS 1.0 or 1.1, you must update that configuration or add-on to TLS 1.2 or later as soon as possible. For more information, see Blog post: Update to TLS 1.2 or later in Dynamics 365 Business Central in 2019 release wave 2.
