What is DrDoS Attack in Computer Network? – A Distributed Reflection Denial of Service (DrDoS) attack is made by sending a fake request to the attacker’s target computer system, by changing the source address to the address of the target computer.

What is DrDoS Attack in Computer Network?

DoS attacks are done to prevent the target computer from serving. In the previous article, we talked briefly about what is DoS and what is DDoS. In this article, we will talk briefly about what is DrDoS attack and how it is done.

DrDoS attack is a type of DDoS attack and the biggest difference is that the source address is misleadingly changed to the target computer address. DrDoS attacks are the most effective and lasting DDoS attacks.

DrDoS attacks are also performed using multiple computer groups as in the same DDoS attacks. It attacks or reflects to the victim by using this computer group.

In the DrDoS attacks, it is generally used server computers rather than end-user computers.

Protocols Used in DrDoS Attack

The protocols used for DrDoS attack are listed below.

1. DNS (Domain Name System)
2. NTP (Network Time Protocol)
3. SNMP (Simple Network Management Protocol)
4. CHARGEN (Character Generator Protocol)
5. SNMPv2
6. NetBIOS
7. SSDP
8. QOTD

Components of DrDoS

DrDoS attack has 5 components. These components include;

Best-Selling-Routers
Best-Selling-Routers

1. Attacker

Attackers control the Handlers for DrDoS attacks. The main intent of the attacker is to shut down the services of the victim computer.

2. Master

Masters or Handlers control Slave machines and make Slave machines ready for attack.

3. Slave

Slave machines are controlled by the Handlers. The slave machines send the victim computer’s IP address as the source address to the Reflector.

4. Reflector

Reflector machines reflect response packets as large volumes of traffic on the victim’s computer.

5. Victim

The victim can be a server or a computer. During the DrDoS attack, the services of the victim computer become inaccessible to locally accessible users.

How to Prevent DrDoS Attacks?

It is almost impossible to prevent DrDoS or DDoS attacks. However, to reduce these attacks, our network environment requires the presence of devices such as Firewall, Intrusion Detection Device.

The following solutions can be applied to prevent or reduce DrDoS attacks.

1. Internet Service Providers must reject spoofed UDP traffic with rogue IP addresses.
2. Network traffic should be monitored to prevent DDoS or DrDoS attacks.
3. It should use DNSSEC extensions to prevent DNS-based attacks.
4. If the network environment does not belong to a business environment, the protocols used in DrDoS attack must be turned off.
5. System updates should always be done to avoid exposure to DrDoS attacks.

  Final Word

What is DrDoS Attack in Computer Network? – In this article, we have briefly talked about DrDoS and how it makes. DrDoS attacks are the most popular type of attack today.
