Do you really believe your statement "An alternative approach (Java + VxWorks) is inherently secure, both from attach and from upgrade failures."?

Apart from the fact that I typoed "attach" when I should have said "attacks", yes. It's the Java part that makes for security: the designers made sure that the Java Applet was a secure as can be, given the limitations of current technology, and security is a central part of the Java 2 API. It's certainly more secure than Windows, which was never designed with security in place, and has only managed to gain any FIPS certification at all when not connected to a network (wow!).

VxWorks itself is not secure, but it's a lot less complex than Windows, in fact less complex by a couple of orders of magnitude in the size of source code it takes to implement it. It is also much more stable than Windows, and has basically been feature-frozen in the kernel for about 5 years. Microsoft are even as we speak, integrating more and more internet functionality within the kernel, which means that that code runs with privileges that allow it to do pretty much anything it wants with the system.

So a Java+VxWorks solution is more secure, and more reliable, since both parts were designed to be so.
