The following custom attributes are defined in the System.Net and System.Security.Permissions namespaces. Note that these are all base classes; the actual instances of security attributes found in assemblies will be sub-classes of these.
| Attribute | Description |

Note that any other security-related custom attributes (i.e., any custom attributes that derive from System.Security.Permissions.SecurityAttribute) included into an assembly, can cause a conforming implementaion of the CLI to reject such an assembly when it is loaded, or throw an exception at runtime if any attempt is made to access those security-related custom attributes. (This statement holds true for any custom attributes that cannot be resolved; security-related custom attributes are just one particular case)
