If your site is political in nature, accepts payments via the Internet, or if you run a profitable business - DDoS attack can happen at any moment. From English, the abbreviation DDoS can be translated as "distributed attack for denial of service." AND protecting the web server from DDoS attacks is the most important part of quality hosting.
Just saying DDoS attack - this is an overload of the server so that it cannot serve visitors. Hackers take over a computer network and send a huge number of empty requests to the right server. The size of a botnet can range from several tens to several hundred thousand computers. The server is forced to respond to all requests, cannot cope with the load and crashes.
Systems for protecting servers from DDoS attacks
Fight DDoS attacks possible by hardware methods. To do this, firewalls are connected to the server equipment, which decide whether to pass traffic further. Their firmware contains algorithms that determine the vast majority of attacks. If the attack power does not exceed the values specified in the certification, the equipment will operate normally. The disadvantage is limited bandwidth and difficulty in redistributing traffic.
More popular approach – use of a filter network. Since traffic is generated by a botnet, using many computers to combat empty traffic is the most optimal solution. The network takes over traffic, filters it, and only verified and high-quality traffic from real users reaches the target server. The main advantage of this approach is the ability to flexibly configure protection. Advanced hackers have already learned how to disguise malicious traffic as the traffic of ordinary visitors. Only an experienced information security specialist can recognize bad traffic.
To protect against such attacks, providers and hosting companies create networks that allow traffic to pass through and filter it. In extreme cases, it is possible to connect to third-party traffic cleaning nodes.
The network architecture consists of three layers: routing, packet processing layer and application layer. At the routing level, the flow is evenly distributed between network nodes thanks to super-efficient routers. At the packet processing level, several mutually redundant devices filter incoming traffic using special algorithms. At the application layer, encryption, decryption, and request processing take place. If necessary, you can read reports on the power and duration of attacks, as well as read reports on cleaning.
