Computer Security: A Historical Perspective
Roger R. Schell, Edwards E. Reed · Encyclopedia of Quantitative Risk Analysis and Assessment · 2008
Abstract The pervasive dependence on computers today gives us no choice but to use them in the face of professional attackers. That threat, for which software subversion is often the tool of choice, is serious and growing, so computers are increasingly a major source of risk. Responsible risk assessment and risk management requires that we not only create computers that are secure but also verify that we have succeeded. A productive history of more than 30 years of research and practical experience has produced a theory of computer security rich with solutions and tools. The greatest achievement is the demonstrated ability to build and operationally deploy truly bulletproof systems having verifiable protection. This remains the most powerful solution available for many of today's hard computer and network security problems.
