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 cyber security 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 are blocked by anti-virus. See more about this in the defense in depth card.
