	Code access security
	Code access security is evidence oriented, which is linked with a particular assembly. Characteristically the evidence is the source of the assembly. It is either directly installed on the native machine or can be downloaded from the internet. Evidence is used by code access security to verify the permissions granted to the code. Other code can demand that calling code is granted a specified permission. The demand results in the CLR performing a call stack walk. In this process every assembly of each method in the call stack is verified for the required permission.

	Validation & Verification
	Validation & Verification are the two tests performed by CLR when the assembly is loaded. During the validation process the CLR verifies the presence of metadata & CIL and also verifies for the validity of internal tables. By deploying a few algorithms the verification mechanism checks to see if the code does any thing that is 'unsafe'.
