Bill Shooter of Bul,

"If there are kernel security experts here, they don't have access to their product and can't evaluate their claims. If there are not kernel security experts here, their product hasn't earned the respect of the experts elsewhere."

Sure, those are valid concerns for people interested in buying the product.

"Its not really worth discussing the potential security benefits of an untrusted, untestable system."

I disagree, Alex may very well have some valuable insight to contribute to a discussion on linux security. I am interested in the mechanisms used to control access in the kernel and it is worth discussing regardless of whether the product is proprietary or not, IMHO.

"So, people end up focusing on the crazy claims of espionage and international three letter acronym intrigue that make this seem as shady as a back alley kidney transplant."

Yes, I don't think Alex was expecting this. He got off on the wrong foot.

Technical questions for Alex:

1. What kind of context does HSS consider when deciding whether to permit or deny a request?

2. When a process executes "su", does the kernel invoke a userspace permission check through IPC? Is this somehow cached in the kernel, or repeated for every security check?

3. You indicated fewer scripts were required to use HSS, are events scriptable under HSS or do they have to follow a strict pattern engine?

4. How does HSS deal with concurrency? In particular, can the userspace portion handle parallel IPC requests (assuming there is a userspace portion) or are they serialized?

5. What is the impact to performance when the permission checks are enabled?

6. Does HSS do anything special to help debug app problems caused by restrictive permissions? How do I determine why my app is failing?

7. Does HSS work with a customized kernel?

8. Are the configuration files human read/writable or are they binary?

And I might as well ask, are you hiring english speaking devs?

Well, It was a sales pitch with minimal technical info. If they wanted to discuss the technology behind it, thats great they should have tried that instead of the sales pitch.

But for what its worth Google translate does a fair job on their whitepaper. it doesn't make me feel any more comfortable about the product, but you might find some good discussion points*~...
