In this article, I will try to explain what DDoS is, and how it can be prevented or mitigated. Many of the servers in datacenters these days are Linux-based; hence, I'm going to discuss DDoS attack prevention and mitigation for Linux servers.
DDoS happens due to lack of security awareness, application, or skill on the part of the network/server owners or adminstrators. We often hear that a particular machine is under DDoS attack, or that the NOC has unplugged a given machine due to its participation in a DDoS attack. DDoS has become one of the common issues in our world. In some ways, DDoS is like a disease which doesn't have a countering antibiotic, and requires being very careful while dealing with it. Never take it lightly. In this article, I'll try to cover the steps/measures which will help us defend our machines from a DDoS attack - at least up to a certain extent.
