As Internet grows so does the different threats you can be exposed to, especially if you like me are running your own Internet services. I will not claim that I'm an IT-security expert in anyway, but there are a few things I still would like to share. The worlds leading webserver today is Apache. Apache runs under different Linux distros and Windows. Together with PHP and MySQL you have a powerful platform to build your own webapplications on. To develop web solutions on Apache is one thing, but putting them to work in the real world is another thing.
