When a new row is inserted into a table, or when a column in a row is updated, the SQL Server database calls the EKM Provider software to perform encryption.

As its name implies it encrypts data in a column in a table. The EKM Provider architecture supports two different methods of database encryption:Ĭell level encryption is also known as column level encryption. This has provided a stable and predictable interface for Microsoft customers and key management vendors.ĮKM Architecture - column and database encryption

The EKM Provider architecture opened the door for third party key management vendors to extend encryption to include proper encryption key management.įrom a high level point of view the EKM architecture looks like this:Įvery version of SQL Server since 2008 has fully implemented the EKM Provider architecture. EKM Provider software performs encryption and key management tasks as an extension to the SQL Server database.

This is named the “Extensible Key Management” Provider interface, or the “EKM Provider”. Starting with SQL Server 2008 Enterprise and SQL Server Standard 2019 the database implements a Provider interface for encryption and key management. If done correctly the Provider interface provides powerful extensions to Microsoft applications. The third party software must obey rules about the data interface and behavior of their applications. With Provider architectures Microsoft enables a method for third parties to register their software to the Microsoft application, and the Microsoft application will then call that software as needed. This is the term that Microsoft uses to describe a standardized, pluggable architecture for third party software companies to integrate and extend the capabilities of Microsoft solutions. Many Microsoft applications and services implement a “Provider” interface. This page will discuss how Microsoft implemented encryption in SQL Server, how you can leverage this capability to achieve better security and compliance, and the critical issues involved in getting encryption right with SQL Server.

This was a prescient and crucially important enhancement for Microsoft customers - the security threats have increased over time and compliance regulations have become more stringent. The compliance environment was changing dramatically and the SQL Server group at Microsoft provided a path to meet those new compliance regulations. In addition to the PCI standard which mandated encryption of credit card numbers, numerous states in the US had also adopted data breach notification laws with strong recommendations for encryption. In 2008 the Payment Card Industry Data Security Standard (PCI- DSS) was gaining serious traction and Microsoft released SQL Server 2008 with built-in support for encryption.
