SecurityPermissionFlag.Assertion Field

Assertion = 0x1;

Summary

Specifies the ability to assert that all of the callers of the code granted this permission will pass the check for a specific permission or permission set.

The ability to assert a specific permission or permission set allows code to ensure that its callers do not fail with a security exception for lack of the specific permission or permission set asserted.

[Note: Asserting a permission is often used when writing library code that accesses protected resources but itself does not expose these resources in any exploitable way to the calling code. ]

ControlThread = 0x10;

Summary

Summary

Specifies that none of the permissions in this enumeration are available.

SecurityPermissionFlag.SkipVerification Field

SkipVerification = 0x4;

Summary

Specifies the right to skip the verification checks that ensure type safety and metadata correctness in an assembly. If an assembly has been granted this permission it will not fail with a VerificationException even if the assembly contains unverifiable constructs.

[Note: Code that is unverifiable can execute without causing a VerificationException if this permission is granted.]

SecurityPermissionFlag.UnmanagedCode Field

UnmanagedCode = 0x2;

Summary

Specifies the ability to call unmanaged code.

[Note: Because unmanaged code potentially allows other permissions to be bypassed, this permission should be used with caution. It is used for applications calling native code using PInvoke.]
