Dwayne is concerned that he won't know if a website he visits is safe. What if it's been compromised by a hacker? How would you know until it's too late? Leo says that most of us aren't really the target of a hack unless it's a mass attack. And those are a lot easier to defend against. Website attacks are a very common attack, where a hacker will forge the look of a website in an attempt to get you to log into it and steal your login credentials. This happens with bogus bank links. So it's important to be very careful on the links you click on.
Websites can also have certificates, which verify that the site is legit. So you can look at the certificate to be sure it's the website you should be at.
But even legitimate websites can be compromised and malware installed on them without anyone knowing. Your browser needs to be updated to combat it. So always make sure your browser is updated. Chrome, for instance, gets updated automatically.
