If you are the owner of a web site then you probably have the same ambition as everyone else who owns a web site. You want to be able to say that you have a lot of people who visit your web site every month. While some people run web sites because they enjoy doing it and other people run web sites because they enjoy the money that comes along with it, all of these people have the same goals in common. They both want to have a lot of people come to their web site.
But you have to remember that while it is a good thing when your web site starts to become more popular, there are negative side effects as well. These are side effects that you did not have to think about before. Just like with anything else in life, when you start to become successful, you start to see a different type of problem. And in the world of the web, it is no different.
With more eyes being on your web site, this means that you have to worry about the bad guys now being exposed to it as well. When you were a small web site puttering along, this was a concern that you most likely did not have. But now that people are starting to go to your web site, the bad guys are going to try and find a way to exploit it. Even if you are not making money off of your web site that does not mean the bad guys will not try to find a way to do it. All they have to do is find one little hole and they can cause real problems for your visitors.
If you are the one who made your web site then you need to make sure that you start to learn proper security techniques. You are not finished with a project until it is properly secured. If you are not the one who created the web site then you need to hire someone who will be able to help you secure it. There are plenty of services who do this. And if you use a pre built CMS then there are services out there that specialize in that type of security alone.
When you become popular as a web site, you have to think about the good and the bad. But a popular web site welcomes this type of problem.
