Hackers may be able to fool you into believing that their web site is actually a web site (such as a bank or credit card web site) that you trust. This may be done by misleading email, or even by breaking into the network infrastructure and rerouting network traffic destined for, say mybank.com, to the hacker’s site. If you enter your user name and password on the hacker’s site, the site can record it and use it later to break into your account at the real site. When you use a URL such as https://mybank.com, the HTTPS protocol is used to prevent such attacks. Explain how the protocol might use digital certificates to verify authenticity of the site.
