Schneier's 5 Questions

While talking about fingerprinting students on Buses, Schneier gives us five questions to use to evaluate Secuirty Countermeasures:

  • What assets are you trying to protect?
  • What are the risks to these assets?
  • How well does the security solution mitigate those risks?
  • What other risks does the security solution cause?
  • What costs and trade-offs does the security solution impose?
