We want to be secure and not the dupe of liars and dissemblersTrust is essential for many aspects of society, not just business
A joke in search of a punch line:What is the difference between a sociologist and a mathematician?
Value = the value to the trustor of the particular OutcomePayoff = expected value to the trustor over the long term with repeated occurrences of the ActivityRationality = average case behaviourBUT if the worst case causes catastrophic consequences (with very low probability), then risk averse players will not take it, even if the expected value over the long term is positive
Trying to add my input as a mathematician
Dependability is that property of a computer system such that reliance can justifiably be placed on the service it delivers. It generally includes the notions of availability (ability to use a system or service) and reliability (continuous operation of a system or service), as well as integrity, maintainability, and safety. Security is the property of a system and measures taken such that it protects itself from unauthorised access or change, subject to policy. Security properties include AAA (auditability, authorisability, authenticity), confidentiality, and nonrepudiation. Security shares with dependability the properties of availability and integrity. Performability is that property of a computer system such that it delivers performance required by the service, as described by QoS (quality of service) measures.
