What Is DDoS?


The best web hosting solutions provide ultimate protection from what is otherwise known as a DoS (Direct Denial-of-Service) attack. A DoS attack occurs when an attacker uses a large number of computers on the Internet in a coordinated and concerted effort to send unusually large numbers of unauthorized requests to a server. These requests are usually sent from thousands of different IP addresses with the aim of overload the target server. When a server is forced to respond to a large number of DoS attacks, it will either lose its ability to function normally or be forced to shut down completely.

There are several ways in which a DDoS attack can be executed. One of these methods is the application layer attacks that use a software tool that runs on the targeted system. The application layer attacks are usually employed by attackers who want to send unusually large or multiple requests to a server. The purpose of these types of attacks is to overload the system's systems or services by making use of huge amounts of resources. The most common application layer attacks are by using software applications and programs that run on the computer, Network Interface Card, Communications subsystem and any other peripheral device.

Another method of what is otherwise referred to as a distributed attack is when attackers take advantage of weaker software applications that are running on an infected PC. In some cases the application layer attacks can use a technique called packets flooding. This method is executed by flooding a targeted server with numerous packets of random data which are made to appear as if they are coming from legitimate sources. For example a flood of" HTTP requests" will cause your website to appear like it is responding "load monitoring" messages.

One of the most common types of what is otherwise known as a Distributed Denial Of Service (DDoS) attack happens when attackers to flood a network by using the Internet to send spoofed traffic to specific IP addresses and/or ports. For example, if an IP address is used to launch a flood attack on your business website, the IP address could be replaced with one that has nothing to do with your business in order to trick the network administrator into thinking that the attack originated from the company instead. An example of this would be a Distributed Denial Of Service attack happening on a University's intranet. The attack would not be stopped by an anti-virus application, but it might look like it is stopping because of the many advertisements appearing on the network.


How do you know if what is DDoS? or attack is taking place? For the best protection from what is otherwise referred to as a Distributed Denial Of Service attack, you should not use the Internet or run any applications on it. What is best for DDoS protection is packet filtering. There are many different types of packet filtering software available. Some of the best IP-based packet filtering software available is WAN Polipo.

When there are too many users connecting to a server, the Internet service provider will often overload the routers. This overload can cause the routers to go into what is otherwise known as a "fatal" error state, where all of the data packets are delivered over the entire network rather than over one network of IP addresses. The fatal error state usually results in a catastrophic outage for the Internet service provider, and it can cause many businesses and homes to lose Internet connectivity.

How is a DDoS attack made? A Distributed Denial Of Service is most often started by a single user who sends repeated requests to various IP servers that are used to forward those requests to other IP addresses and servers. By sending multiple requests in a short amount of time, the attacker can greatly reduce the latency that is required for a legitimate user to connect to the Internet service. When a server is overloaded with traffic, it must return an error code to clients, usually indicating a fatal problem. The resulting outage will be felt far beyond the local area where the server is located.

Today, it has become necessary for companies to implement DDoS protection measures to prevent these types of attacks. While traditional methods of stopping DDoS attacks require large numbers of servers, those methods are unsuited for today's world where we experience higher levels of Internet traffic. By using specially designed software, a company can reduce the risk of being attacked by allowing only the number of IP addresses that it allows to utilize the Internet service. In addition to reducing the risk of attack, the use of specially designed DDoS protection software also allows network layer attacks to be managed while new IP addresses are added to the pool of available IP addresses.
