September 11th is an appropriate date for discussing the threat posed by having our own technology turned against us. There's nothing at all amusing in this week's program, but we should start thinking about what the next attack will be like because there will be one. In Short Circuits: Bring your own device (BYOD) to the office and you'll expose your employer to new threats, but that's nothing compared to the dangers posed by computing devices that employees will wear. Some help is available if you want to determine whether a website is safe before you go there. In Spare Parts (only on the website): Healthcare, telecommunications, retail, and transportation industries continue to struggle with security; an Italian company says that the internet will be "safe" within 3 years -- I have my doubts; and government agencies increasingly are using hackathons to engage with developers.
