How To Think About Security?


Bruce Schneier

402 Walter Library

Security is never black or white; it's always gray. To understand whether a system is secure, it's necessary to understand context. What is the trust model? What is the security mechanism supposed to prevent? What are the attacks? Many commercial products are insecure because of a fundamental misunderstanding of what the technologies can and cannot do. This talk teaches how to think about security, by pulling examples from old and new technologies like castles, firewalls, biometrics, elections, slot machines and smart cards. Bruce Schneier will illustrate how someone figures out whether a particular security technology makes sense for a given security application.
