If nobody else posts about the other two, I can within a day or so.. There's also one you don't have listed and that might be part of the. Microsoft Windows [Version 5. Sunday, August 19, AM. To Bob; huh. Well I guess that makes it definitive.
To Yup Went to the first link months ago before entering this thread. Just went to the second link. The access rights in the ACL are:. This service ran as Local System in previous versions of Windows.
To reduce the attack surface of Windows and provide defense in depth, the RPCSS service functionality was split into two services. COM server applications have two types of permissions: launch permissions and access permissions. Launch permissions control authorization to start a COM server during COM activation if the server is not already running. These permissions are defined as security descriptors that are specified in registry settings.
Access permissions control authorization to call a running COM server. Both launch and access permissions allow or deny access based on principals, and make no distinction as to whether the caller is local to the server or remote.
The first change distinguishes the COM access rights, based on distance. The two distances that are defined are Local and Remote. As a side effect of this activation process, sometimes a COM server must be started to fulfill the client's request. The second change is that the call and activation rights are separated to reflect to two distinct operations and to move the activation right from the access permission ACL to the launch permission ACL.
Because activation and launching are both related to acquiring an interface pointer, activation and launch access rights logically belong together in one ACL. And because you always specify launch permissions through configuration as compared to access permissions, which are often specified programmatically , putting the activation rights in the launch permission ACL provides the administrator with control over activation.
This allows the administrator to apply very specific security configurations. For example, you can configure a COM server so that it accepts local access calls from everyone, while only accepting remote access calls from Administrators. These distinctions can be specified through changes to the COM permissions security descriptors. Earlier versions of the COM server application have no way to restrict an application so that it can only be used locally without exposing the application on the network by way of DCOM.
When a user has access to a COM server application, they have access for both local and remote use. In this scenario, the application must also expose its activation to unauthenticated users, which might not be desirable. These permissions enable security for the described scenarios. To provide backward compatibility, existing COM security descriptors are interpreted to allow or deny both local and remote access simultaneously. That is, an access control entry ACE either allows both local and remote, or denies both local and remote.
There are no backward-compatibility issues for call or launch rights. There is, however, an activation rights compatibility issue. If, in the existing security descriptors for a COM server, the configured launch permissions are more restrictive than the access permissions and are more restrictive than what is minimally required for client activation scenarios, then the launch permissions ACL must be modified to give the authorized clients the appropriate activation permissions. For COM applications that use the default security settings, there are no compatibility issues.
For applications that are dynamically started using COM activation, most have no compatibility issues, because the launch permissions must already include anyone who is able to activate an object. Otherwise, such applications generate activation failures even before applying Windows XP SP2 or Windows Server SP1, when callers without launch permission try to activate an object and the COM server is not already running.
The applications of most concern for compatibility issues are COM applications that are already started by some other mechanism, such as Windows Explorer, or Service Control Manager. You can also start these applications by a previous COM activation, which overrides the default access and launch permissions and specifies launch permissions that are more restrictive than the call permissions.
