The Internet, as we know, is probably one of the greatest inventions of human history. Never before has the access to the collection of the world’s knowledge ever been more available. 1. Some people look to make use of the information you are providing to the Internet. Everything you do online leaves a small footprint.

There are a couple of steps you can take to make your adventures online a little safer and more secure. Let’s take a look at them.

Cover your tracks.

Whenever you visit a website, a small file is marked in your browser(浏览器), which is called a “cookie”. 2. This enables the webserver to know if you have been there before and it can tailor the presentation to your personal tastes. They are also how Facebook knows to serve you ads based on stuff you looked at on Amazon.

So what’s the harm in the cookie? Well, hackers can use the information stored in your cookies to edit a browsing history or with less secure cookies, take your passwords for some sites. If you want to protect yourself from your information being available to sites then you can turn off the generation of cookies in your browser. 3.

4.

The major browsers, Chrome, Internet Explorer, Firefox, and Safari are all built to be secure from snooping(窥探), but the people who write the code for the browsers are human and they make mistakes.   5. These are usually addressed very quickly, but it is important that you make sure your browser is up to date. Just like your operating system, new security patches are being applied all the time, you need to make sure you have them. Turning on automatic updates is something I highly recommend.

A.Use the latest browsers.

B.Change browsers frequently.

C.This will help protect you online.

D.That’s how the cookie works on our computer.

E.This great invention and resource is not without its dangers.

F.It is common for a security problem to pop up with a browser.

G.These cookies store information about who you are and what you looked at.
