The whole notion of passwords is based on an oxymoron. The idea is to have a random string that is easy to remember. Unfortunately, if it's easy to remember, it's something nonrandom like 'Susan.' And if it's random, like 'r7U2*Qnp,' then it's not easy to remember.
Interpretation
Passwords are inherently paradoxical, aiming to be both random and memorable but failing at one of these aspects.
This quote by Bruce Schneier highlights the fundamental contradiction in the concept of passwords. While they are designed to be secure through randomness, true security often requires making them complex and difficult to remember, leading to a paradox where easier-to-remember passwords compromise security and truly secure ones are forgettable.
In practice
Discussing cybersecurity during a tech seminar.
History has taught us: never underestimate the amount of money, time, and effort someone will expend to thwart a security system. It's always better to assume the worst. Assume your adversaries are better than they are. Assume science and technology will soon be able to do things they cannot yet. Give yourself a margin for error. Give yourself more security than you need today. When the unexpected happens, you'll be glad you did.
This is not the internet the world needs, or the internet its creators envisioned. We need to take it back. And by we, I mean the engineering community.
It is poor civic hygiene to install technologies that could someday facilitate a police state.
You can't defend. You can't prevent. The only thing you can do is detect and respond.
Digital files cannot be made uncopyable, any more than water can be made not wet.
I am regularly asked what the average Internet user can do to ensure his security. My first answer is usually 'Nothing; you're screwed'.
Technology will save us if it doesn't wipe us out first.
Automated gender analysis of my writings often marks me as male, probably because I write about technology, and also about war. But our algorithmic overlords are onto me: I mostly encounter three types of ads online: weight loss, beauty products, and online degrees from shady for-profits.
An algorithm must be seen to be believed.
We make the best phone, we don't make the most phones.
The decentralized nature of online conversations often makes it easier to manipulate public opinion, both domestically and globally. Regimes that once relied on centralized systems of media control can now deliver ideological messages more subtly, with the help of little-known intermediaries like anonymous commenters on websites.
Mobile phones are misnamed. They should be called gateways to human knowledge.
