Liability and Computer Security: Nine Principles
Ross J. Anderson
Keywords :
Abstract : The conventional wisdom is that security priorities should be set by risk analysis. However, reality is subtly different: many computer security systems are at least as much about shedding liability as about minimising risk. Banks use computer security mechanisms to transfer liability to their customers; companies use them to transfer liability to their insurers, or (via the public prosecutor) to the taxpayer; and they are also used to shift the blame to other departments ("we did everything that GCHQ/the internal auditors told us to"). We derive nine principles which might help designers avoid the most common pitfalls.
