There is very little that is more satisfying in life than to be able to say that you have an idea in your head and you were able to bring it to life. For a lot of people that is hard to do. They are restricted by where they live or how much it cost to fulfill their dreams. When you are a web developer this is not the case. One of the great things about being a web developer is that you are able to have an idea, push a few buttons, and you can see your idea pushed onto the screen. But while I am making it seem easier than it really is, it truly is quite a satisfying experience.
But if you choose a career as a web developer then there is more for you to know than just creating the web pages themselves. You have to realize several things that go on behind the scenes. One of these things is what kind of exploits that are out there which might make your web site unsafe. So that is what I am going to do in this article. I am going to take a look at three exploits that you should really know about as a web developer so that you can make sure that you avoid them. Of course, there are many more exploits out there but I am only going to talk about the most popular ones. It would take too long to talk about all of them.
When you make a web page there is going to be a lot of programming on the back end as well. What I mean by that is that there is going to have to be interaction with the server that the web page is hosted on. This will allow you to be able to make your web site more like a web app. It means your web site will be able to provide dynamic actions.
One of these dynamic actions is to add data from a database. Your database makes it easier for you to add or take away data on the web page when it is needed. But while the database is very useful, it can also cause some security problems as well. One of these problems is known as a SQL injection attack. This attack means that someone was able to use an input form or a malformed web address and use it to manipulate your database without you knowing. This is why you must make sure that all of the data that comes into your web site is validated and scrubbed. This is the only way of preventing this action from happening to your site.
The XSS attack is also known as a cross site scripting attack and it allows someone to come to your web site and inject harmful code inside of it without you knowing. XSS attacks are very dangerous because they can remain undetected for a long period of time and people who come to the site will believe that it is your fault that they were attacked.
Most of the attacks that are XSS based will not have the attack code on your web site directly. They will place code on your web site that will redirect them to another web page which is the dangerous one. Once they are at this second site that is where they will become infected but they will still blame you for sending them there. Once again the answer to this problem is to make sure that all of your data is once again filtered.
While this attack is rarely dangerous it is one of the most annoying attacks that you will see on the web. A DOS attack, also otherwise known as a Denial Of Service attack, is a real pain to deal with. This attack will allow people to stop being able to come to your web site by overflowing your web site connections. Depending on your web host there are only so many people who can connect to your web site at any one time. With a DOS attack, the attacker is making sure that none of those connections are people who really want to enjoy your site. Instead it is junk traffic and totally useless to you.
There is nothing much that you can do to stop the problem. It really all depends on the host that you choose. Some hosts are better than others at stopping problems like this. Make sure that you ask about this before you choose a web host for your web site.
When you are a web developer then there is a lot that you have to know about. While you have to make sure that you know the technologies that are going to help you build your web sites, you also need to know how to stop the exploits as well.
