Guidelines to develope secure ADO.Net application

This is a very comprehensive set of guidelines in making your ADO.Net secure.

Writing a secure ADO.NET application involves more than avoiding common coding pitfalls such as not validating user input. An application that accesses data has many potential points of failure that an attacker can exploit to retrieve, manipulate, or destroy sensitive data. It is therefore important to understand all aspects of security, from the process of threat modeling during the design phase of your application, to its eventual deployment and ongoing maintenance.
