Cybersecurity engineering

Cybersecurity engineering and privacy engineering focus on information security, computer security, and network security, including protecting data from unauthorized access, use, disclosure, destruction, modification, or disruption to access. Physical security involves deterring attackers from accessing a facility, resource, or information stored on physical media. Security engineering involves aspects of social science, psychology (such as designing a system to "fail well", instead of trying to eliminate all sources of error), economics (see economics of security), mathematics, and architecture. Some of the techniques used, such as fault tree analysis, are derived from safety engineering.
