Don't Get Hacked!

We all want to keep our computer systems secure, but how? Too much of the advice we see is wrong (“Don’t click on suspicious links”—how are you to know if it’s suspicious, or where it really goes?) or outdated (“Use strong passwords and never write them down”—notions that date to 1979, when the technology world was very different). In Don’t Get Hacked!, Steven Bellovin gives practical, real-world, up-to-date advice, without jargon. He explains the threats and what to do about them, and why—and what threats you probably don’t have to worry about. From backups to two-factor authentication to AI, you learn what the real issues are, such as why your email account is probably your most important and why it needs the most protection. You also learn where security is not all-or-nothing—while upgrading your hardware when necessary is a good idea, Don’t Get Hacked!, shows what to do if you can’t.

@SteveBellovin You mean I can fetch a free copy without penetrating three firewalls, distracting two guards, inserting a trojan into an operating system boot loader, and prompting an AI to grab a copy? Gee, what fun is that?

@SteveBellovin

Fantastic! Thank you for creating such a useful resource. I often felt deflated when having to deal with the lack of materials useful for the less tech savvy.
