How does Security affect Performance?

Dec 26 2007 4:22 PM
Dear All,

I'm new to .NET tech. I was going thru my material and came thru below mentioned security options in .NET

a) Evidence based,
b) Role based,
c) Policy Driven,
d) BCL Security

I'm interested to know whether it possible to create an application with the combination of above security options? If
it's possible what would be its effects on the performance.
