Speaking of these products, how much confidence do we have in the financial stability and future of the companies that build them? How do they hold up? We can debate the technical merits all day, but if the company turns to fairy dust of any colour, what use is the software? Anton J Aylward

Secure computing makes a trusted operating system (called LOCK, if I recall correctly) but Sidewinder was based on BSDI with some orange book fairy dust blown on it - I don't think it was a _real_ trusted operating system, just good old BSDI(which isprobably better) with some hacks in it to include the domain/type enforcement stuff.Yes, I classify Sidewinder on BSDI as a trusted OS (in addition to the LOCK stuff), because it implements a mandatory access control policy which is universally applied and it provides the ability to control privilege operations, both of which are defining characteristics of a trusted OS (along with the design/implementation process thatis intendedto meet evaluation criteria). The fact that domain type enforcement is not a Bell-LaPadula model doesn't eliminate it from the running. What is "orange book fairy dust"? paul --------------------------------------------------------- Paul A. McNabb, CISSP Argus Systems Group, Inc.
