How Not to Get Hacked

The Internet is open, so everything that happens on it can be seen unless it's protected. In modern countries, people are more worried about getting hacked than about any other crime. Why? Because every computer or phone on the Internet is regularly being tested for vulnerabilities by criminals, terrorists, or even state actors. If you're not careful, somebody could hack your device or accounts, and even steal your identity or your money.
