How to create a no security level kernel object

I make a sample of Event object to show this issue:
How to create a no security level kernel object?

    SECURITY_DESCRIPTOR    sd;
    InitializeSecurityDescriptor(&sd, SECURITY_DESCRIPTOR_REVISION);
    SetSecurityDescriptorDacl(&sd, TRUE, (PACL)NULL, FALSE);

    SECURITY_ATTRIBUTES sa;
    sa.nLength = sizeof(SECURITY_ATTRIBUTES);
    sa.bInheritHandle = FALSE;
    sa.lpSecurityDescriptor = &sd;

    HANDLE MonitorEvent = CreateEventA(&sa, FALSE, FALSE, "Global\\{A7DF02C8-0F89-4a3b-A6E8-E3E08C167C58}");

You can do the following operation to set the event in another process

    HANDLE hMonitor = OpenEventA(EVENT_ALL_ACCESS, FALSE, "Global\\{A7DF02C8-0F89-4a3b-A6E8-E3E08C167C58}");
    if ( NULL == hMonitor )
    {
        cout << "Open event failed, last error:" << GetLastError() << endl;
        return 0;
    }

    SetEvent(hMonitor);

Why I make this sample?
Because I want to operate a windows kernel object in the different process, and these process own the different security level. e.g. service and user process. So if you don't set the security descriptor , you will always get the NULL when you invoke OpenEvent API and get the error number is 5.
