There are tons of thoughts and information how to secure/authorize functionality in a system, e.g. web application. But there are few discussions about how to authorize access for records/business entitier in a database. My question is if anyone has interesting ideas or have solved this rather common business problem with the securityblock from Microsoft?
What I do need is to filter the business response transparent for the enduser/client.
