Why JavaScript Defense Is So Important For The Security Of Your Web Site

In the past when you would mention the words JavaScript then a person in the web industry would probably give you a weird look. There were many knocks against JavaScript back then. Some of the knocks included it being a toy language and that no serious programmer would ever use it. Other people thought that it was too complicated for the average web developer to use and that it should be replaced. JavaScript was not really a respected language and its reputation would remain that way for a few years.

Why JavaScript Defense Is So Important For The Security Of Your Web Site

The reputation of JavaScript was turned around by a feature that was initially created by Microsoft but was then implemented by other browsers. The feature was called Ajax. It allowed a browser to more easily talk to the back end server without needing to refresh the actual web page that it was on. When people saw the potential of this feature they started to use it in droves. It seemed like overnight, JavaScript turned into being one of the most hated languages out there to being one of the most beloved. Now you see it being used heavily on most of the web pages that you visit. It has gotten so popular that now people are making server side versions of apps in JavaScript. That was unheard of a few years ago.

But with this rise in popularity when it comes to Javascript, you also have to be careful of the downsides. If you have a web site and you want to run a heavy amount of JavaScript on there then you must be sure that you know how to protect it as well.

JavaScript is what is known as a client side technology. This means that for it to run it is implemented in the browser. While for the most part this is a good thing, it does have some bad affects as well. This means that your source code is exposed by anyone who wants to see it. The good guys and the bad guys have the ability to examine the code for weakness. And you have to believe that if there is any weakness there then someone will find it.

So if you want to protect yourself against these weaknesses then make sure you are up to date on JavaScript security measures. Your visitors will thank you for it.
