[Chat GPT]DDoS 공격 종류 설명

DDoS attacks aim to disrupt websites, networks, or servers by overwhelming them with traffic. There are five types of DDoS attacks: volumetric, TCP state-exhaustion, application layer, protocol, and fragmentation. Organizations should take steps to protect themselves against these threats.

# DDOS Attack Type Description

Distributed Denial of Service (DDoS) attacks are one of the most common cyber threats that organizations face. These attacks aim to disrupt the normal functioning of a website, network or server by overwhelming it with a high volume of traffic. This can lead to downtime, loss of revenue, and damage to an organization's reputation. In this article, we will discuss the different types of DDoS attacks that organizations should be aware of.

## 1. Volumetric Attacks

Volumetric attacks are the most common type of DDoS attack, accounting for over 80% of all attacks. This type of attack floods the targeted website or network with a large volume of traffic, overwhelming its bandwidth and causing it to crash. Volumetric attacks can be launched using a variety of techniques, including UDP flooding, ICMP flooding, and DNS amplification.

## 2. TCP State-Exhaustion Attacks

TCP state-exhaustion attacks aim to consume the resources of a targeted server by exhausting its connection resources. This type of attack exploits the way that TCP connections are established and maintained, by sending a high volume of fake connection requests to the targeted server. This causes the server to allocate resources to each request, eventually leading to an overload and a denial of service.

## 3. Application Layer Attacks

Application layer attacks are also known as Layer 7 attacks, and they target the application layer of a website or network. This type of attack aims to exploit vulnerabilities in the application layer, such as flaws in the code or design of the website or application. Application layer attacks can be launched using a variety of techniques, including HTTP flooding, Slowloris attacks, and SQL injection attacks.

## 4. Protocol Attacks

Protocol attacks target the network protocols used by a website or network, such as TCP, UDP, and ICMP. This type of attack aims to exploit vulnerabilities in the protocol itself, such as flaws in the implementation or design of the protocol. Protocol attacks can be launched using a variety of techniques, including SYN flooding, Ping of Death attacks, and Smurf attacks.

## 5. Fragmentation Attacks

Fragmentation attacks aim to exploit vulnerabilities in the way that data is fragmented and reassembled by a server or network device. This type of attack can be launched by sending a high volume of fragmented packets to the targeted device, overwhelming its resources and causing it to crash. Fragmentation attacks can be launched using a variety of techniques, including IP fragmentation attacks and TCP fragmentation attacks.

## Conclusion

In conclusion, DDoS attacks are a serious threat to organizations, and it is essential that they understand the different types of attacks that they may face. By being aware of the various attack types, organizations can take steps to protect themselves against these threats. This may include implementing DDoS mitigation solutions, such as firewalls and intrusion prevention systems, or working with a managed security service provider to monitor and respond to attacks in real-time.
