Linux security tutorials
In computer security, it quickly becomes apparent that preventing computer attacks is much more challenging than attacking computers. A good example of an easy technique to prevent a website from functioning is a distributed denial of service, or DDoS, attack in which a number of compromised computers around the internet make web (or other protocol) requests on some poor server. If the web page requested is one that requires lots of server-side processing, the resulting load from the combined requests prevents the web server from responding to legitimate requests, thus denying the service. As Tech-Recipes.com was subjected to such an attack recently, we felt it might be beneficial to others if we described the steps we took in our response.
