The online gaming industry often suffers many complex and changeable large traffic attacks, such as DDoS attacks. With so many types of DDoS attacks and the increasingly new methods to perform a DDoS attack, game experience has been greatly affected.
What is a DDoS attack?
DDoS attack is the abbreviation of Distributed Denial of Service attack. So what is a Denial of Service attack? All attacks that make legitimate user unable to access network services are DoS attacks. That is to say, a DoS attack aims to prevent legitimate users from accessing normal network resources.
To put it simply, many people pretend to be ordinary customers to crowd a shop, while real shoppers cannot get in. They take different methods to prevent the shop from serving real customers. Then, the shop will suffer big losses.
In addition, a lot of people are needed to achieve this goal.
DDoS VS. DoS
Although DDoS attacks and DoS attacks are similar to each other, they are quite different in some aspects. DDoS attacks work by using the botnet to send packets that seem legitimate to the target, which causes network congestion and server resource exhaustion. As a result, the target is overwhelmed with numerous faked packets. Once a DDoS attack is performed, legitimate users will be unable to access the server.
Therefore, distributed denial of service attack is also known as “flood attack”. Common types of DDoS attacks include SYN Flood, UDP Flood, ICMP Flood, HTTP Flood, etc. DoS attacks, on the other hand, cause website outage, system and host crash to make the host unable to provide services. It exploits specific vulnerabilities on the host. Teardrop attack, Shrew attack, Slow Read Attack, Nuke, Banana attack and Peer-to-peer attack are common types of DoS attacks.
Compared to a DoS attack, it is more difficult to avoid a DDoS attack due to its nature. DDoS attacks are distributed so that you can hardly prevent them completely.
How to perform a DDoS attack?
DDoS attack uses a large number of faked requests to occupy the network resources in order to cause network paralysis.
- Overload the network to interfere with or interrupt network communication.
- Overload the server by submitting a large number of faked requests.
- Block a user’s access to the server.
- Prevent a particular system or person from communicating with a service provider.
Many techniques can be exploited to perform a DDoS attack.
IP spoofing means that the hacker sends a faked packet to the server. To be specific, the source IP address included in the packet is changed to one that is invalid or doesn’t exist. Thus, when the server responds to this request packet, the source IP will never receive the packet returned by the server. This will eventually wast resources of the server.
ICMP flood is to occupy the system resources by sending broadcast information to the poorly set router.
Different from the attacks mentioned above, application-level floods focus on the application layer which is higher than OSI.
It is also designed to consume a large number of system resources by sending unlimited resource requests to Internet services such as IIS to affect normal network services.
How to prevent DDoS attacks while gaming?
DDoS attacks are becoming more and more difficult to defend against because they are distributed denial of service attacks. A DDoS attack can target multiple system resources in multiple locations, causing the target system to be completely overwhelmed.
It is impossible to only rely on a system or product to prevent DDoS attacks. Since both DDoS attack and defense cost money, if you take measures to avoid DDoS attacks, the attacker will spend more on performing a DDoS attack. In this way, you will reduce DDoS attacks from the Internet.
For gamers, VPNs not only allow you to play games that are not available in your home country but also protect you from DDoS attacks. While playing the game, your IP address could be exploited by an attacker to launch a DDoS attack. But if you use a VPN, it will only see the IP address of the VPN server, not your IP address.
Besides, using a VPN brings you a lot of benefits. You can unblock websites with a VPN. It also allows you to browse anonymously on the Internet. We recommend you to download RitaVPN, which is really easy to use. You don’t need any extra techniques.
