A risk-benefit analysis should include at least five factors: No matter how carefully and thoroughly one executes all possible preventive measures, it is necessary to ask: Although these three bases apply in general...

Consequently, the approach is hardware-oriented, with the emphasis on ensuring that hardware is able to perform its intended function. Backup systems and redundancies are also used to reduce such risks. Through cost/benefit analysis...
