Making sure you have strong passwords, antivirus installed, and a firewall on your computer is an example of which principle?
If you had a million dollars, would you just hide it in your room? Probably not, you would hide a secret password, lock that password in a safe, and use the password to access a top-secret bank vault that holds your money. Think of doing the same thing with cybersecurity and protecting your information. Even if a hacker gets past a firewall, they have to contend with user password protections. Even still, the tool they may use to get past those is blocked by antivirus. See more about this in the defense in depth card.
