This code-access permission controls access to a set of 14 discrete operations that are critical to the security of the runtime environment. These include highly trusted operations, such as the ability of code to control evidence, create and manipulate application domains, and skip verification. The specific operations represented by a SecurityPermission object are identified at construction using members of the SecurityPermissionFlag enumeration. To retrieve or modify the operations represented by a SecurityPermission object, use the Flags property.
