The values of the SecurityPermissionFlag
enumeration specify the security actions that a
SecurityPermission or
SecurityPermissionAttribute object represents. Of
the values we have discussed in this book, the most fundamental value
is Execution, without which code cannot run in the
.NET Framework. SkipVerification gives
unverifiable code permission to run, and
UnmanagedCode gives code the ability to run
unmanaged (native) code through PInvoke or COM interoperability
calls. Assertion allows code to assert any
permission that it has been granted—see the
System.Security.IStackWalk interface for details.
ControlAppDomain represents the ability to create
and manipulate application domains,
ControlDomainPolicy allows code to assign security
policy to an application domain, and
ControlPrincipal controls the ability of code to
manipulate the principal of an application domain (used in role-based
security). ControlEvidence allows code to
manipulate the evidence of an application domain as it is created or
an assembly as it is loaded, and ControlPolicy
means that code can view and manipulate security policy.
The AllFlags value represents a combination of all
values, and NoFlags represents no permission. Any
set of security operations can be represented using logical OR
operations to combine the member values.
