The problem with the internet as it is today is that not many people know how to use it effectively. We still have several generations of people who grew up without having a computer in the house. Now that computers have become so important they are what you would call a little behind the curve. For example, if you take another complicated machine like a car, you will see that even people who are not mechanics know the basics of how to keep it running. They know that the oil needs to be changed after so many miles. Many also know how to fix their own tyre if it goes flat. This comes from the automobile being around us for almost one hundred years.
Until the internet has spent that length of time in the public space, there are still going to be people who think that it is magic. They cannot comprehend how anything on the machine really works and so they do not even try. You can take, for example, the browser and how many people still do not get the technology behind it. Even though these people use a browser everyday they still do not what it is.
And this is where the security problems come into play. Knowing your browser better would help you in so many different ways when it comes to security attacks. You do not even have to know that much about it. Just know which browser you are using and the basic features of it.
If you know what browser you are using and what version it is, then you would know when you have to update to a better version. A big example of this is people using Internet Explorer 6 or 7. These two browsers still have a lot of holes in them and they are not able to operate a big percentage of the modern web sites out there. If you knew how to update your browser then that would solve a lot of the security problems that you might have.
On the security side, if you pay attention to your browser then you would know that it gives off a lot of clues when you surf the web. For example, it lets you know when you are on a secure web site by placing a lock in the address bar. By doing that then you know that your communications with that web site are encrypted. If you look closely there are many other signs that your browser will give you as well.
Knowing your browser will help you when it comes to security problems. Just learn a few of the basics and you should be fine.
