BSD-based operating systems are considered very secure. More so than Linux, in fact. Now, there are many reasons why this may or may not be so, including the market share, the speed and quality of software validation, the release cycle, the internal security mechanism, the skill and mentality of developers, administrators and users, the deployment setup, and many other factors, all of which are highly debatable.
Politics and myth notwithstanding, choosing BSD as the foundation for an operating system that dabbles in security is not a bad thing. This is exactly what Kevin and Nancy McAleavey did, creating an operating system that bears their initials in the official project name. Formerly of BOClean and later Comodo, the pair has mostly focused on Windows security, so the leap into the world of UNIX is an interesting and intriguing choice. KNOS is designed to be a secure, live-use only operating system, which should help users avoid any security breach from now till the end of time. The concept is sound, but what about the actual software? Let's find out.
The KNOS Project is not a free product. You can trial a limited demo that does not have software updates or purchase the complete system for one cent shy of USD35, with annual subscriptions. So, the financial factor already comes into the equation.
