I tend to consider it the other way around. Security is a subset of availability. Availability must also take in to account things like hardware failures, network problems, software configuration, etc. It also must account for security. As a sysadmin, my primary interest is not in the security of my services (if it was, I'd unplug them all!), but in the availability. Because security is one aspect of availability, I must account for it when designing and maintaining systems, but it can't be the ultimate goal, since a truly secure system provides no availability. noah
