About this book
Most security advice for ordinary people fails in the same way: it lists forty things you should do, ranks none of them, and leaves you feeling guilty instead of safer. The result is that people do nothing, or they do the easy visible things and skip the two that would actually have stopped the attack.
The Digital Fortress takes the opposite approach. It works out which handful of habits absorb the overwhelming majority of real-world risk to a normal person — your money, your accounts, your photos, your family — teaches those properly, and then tells you plainly which of the remaining advice you have permission to ignore and why.
It assumes no technical background and never asks you to become an enthusiast. Every chapter explains the attack before the defence, so you can tell when a rule applies and when it does not, rather than following instructions you do not understand.
What you will learn
- Which accounts are worth protecting first, and why email outranks everything else
- How to set up a password manager and two-factor authentication once, properly, without a weekend project
- How to recognise phishing and social engineering by structure rather than by memorised warning signs
- What to do in the first hour after a breach, a lost phone, or a compromised card
- How to back up in a way that survives ransomware rather than syncing the damage
Read this if
- You have been meaning to sort out your passwords for about two years.
- You are the person your family calls when something looks wrong on their screen.
- You run a small business and there is no IT department to escalate to.
- You want to know which security advice you are allowed to skip.
Skip this if
