The Ultimate Guide to DDoS Protection

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.VPN

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.
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

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

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. When comes to the issue of online privacy and security, we suggest to use a VPN, and our recommendation is RitaVPN.Qwer432
