Step 1) Read "Secrets & Lies"
Step 2) Realize, after reading the book, that unless you're an expert in
cryptography, you're probably not qualified to build a secure system. 

Seriously. The book is a must-read. My main conclusion from reading it
is that security can only be done properly by experts. I felt
particularly justified when I was able to completely break the password
scheme on a competitor of my client's product in about 20 minutes. 

That said, you often find that people don't really care about making
something actually be secure. They just want to set it up so users
without a clue can't do what they're not supposed to most of the time.

Yes, this is a very common problem. No, there's nothing I know of in the
framework that would take care of this. There may be third party
products that let you define your security on individual data objects.
