Step 9. User Security > Types of Security

Types of Security

In the past, all the building blocks to create application security were there in ColdFusion, and developers went about developing their own custom systems to implement security. When it comes to dealing with users, there are two basic types of security: authentication and authorization.

Authentication deals with verifying who a user is. We need some way to verify that a user trying to access secure areas of our site is in fact who he claims to be. This is typically accomplished with a “what you know” type of approach. That is, if you really are who you say you are, you should know what password is stored against your username. If you don’t know that, you are probably not who you claim to be. This is not a foolproof system, of course, but it is adequate in many instances.
