When you are prepared to start a web site then there are several parts of the process that you may pay attention to more than others. For most people their first thought is how the web site is going to work and how it is going to look. What is not thought about as much is how good the server is that you are using. If you are using a weak server then you will find out soon enough. When your site starts to gain visitors you will start to see issues such as penetration and DDOS attacks.
To keep this from happening you must make sure that your server is prepared before you launch the site to the public. You do not want to try to fix everything while the site is live. Of course you are going to have to be prepared to make some repairs while the site is live but if possible you will want it all done ahead of time. But the one thing that you cannot prepare for is security patches issued by the software that you are using. This can really start to trip you up if it is not handled in the right way.
No matter how much you pay for software or how good of a reputation it has, you are still going to have to worry about software patches somewhere down the line. And we are not talking about software that affects how the program works. We are talking about the security patches that are going to be issued. Holes happen in every piece of software created and if not taken care of will be the entry way to the bad guys on your server.
And we are not just talking about the server software. We are talking about the other software that is installed on the machine besides the server software. The calendar software or the email software that is installed can be turned against you. Whatever the bad guys can do to be able to get into your server they will try.
This is why you have to pay attention when security patches are issued with the software that you use on a server. While there may seem to be a lot of them they are issued for a reason. They are serious security holes that can affect you down the road. And if you ignore them you will find that out quickly on your own.
