Risks of Password Managers

Stuart Schechter writes about the security risks of using a password manager. It’s a good piece, and nicely discusses the trade-offs around password managers: which one to choose, which passwords to store in it, and so on. My own Password Safe is mentioned. My particular choices about security and risk is to only store passwords on my computer — not… Continue reading Risks of Password Managers

What Happened to Cyber 9/11?

A recent article in the Atlantic asks why we haven’t seen a"cyber 9/11" in the past fifteen or so years. (I, too, remember the increasingly frantic and fearful warnings of a "cyber Peal Harbor," "cyber Katrina" — when that was a thing — or "cyber 9/11." I made fun of those warnings back then.) The author’s answer: Three main barriers… Continue reading What Happened to Cyber 9/11?

At the front: a large, square white plate, the terahertz… Continue reading Terahertz Millimeter-Wave Scanners

John Mueller and Mark Stewart on the Risks of Terrorism

In the United States, for example, some six people have perished each year since 9/11 at the hands of such terrorists — vastly smaller than… Continue reading John Mueller and Mark Stewart on the Risks of Terrorism

They do not work as currencies, they are grossly inefficient, and they are not meaningfully distributed in terms of trust. Risks involving cryptocurrencies occur in four major areas: technical risks to participants, economic risks to participants, systemic risks to… Continue reading Nicholas Weaver on Cryptocurrencies
