DDoS Defense Solution

What is DDOS attack?

DDoS attack, Distributed Denial of Service Attack (DDoS), is an attack that sends a large number of malicious requests to a target server by controlling a large number of botnets to exhaust the resources of the target server. Its main feature is that the source of the attack is spread all over the world, and it is difficult to stop it by blocking a certain IP, and secondly, DDOS can take advantage of a variety of protocol loopholes and camouflage normal requests, which cannot be recognized by traditional firewalls at all.​

How DDoS attacks work?

 1. Formation of botnets
Hackers use viruses to control devices around the world, not limited to computers, servers, cell phones, cameras, and other smart devices. By controlling these devices and writing viruses to control these devices to launch attacks.
 2. Execute attack commands
The hacker sends a large number of malicious requests to the target server through the controlled devices to bring down the target server. In general, hackers will find the vulnerability of the target server, specifically for this vulnerability to launch attacks, for example, control 1w devices to CDN5.com to launch a request, such as 1 per minute, 1 hour is 360 million visits, every day is 8.6 billion, the general server can not deal with so many requests, the general server directly down.
 3. Renting botnets
 Now on the market a lot of rental botnet, the attacker can directly rent someone else's botnet by the hour, to the target to send DDOS attacks. So, now DDOS is very frequent, you simply need to master what knowledge, you can launch an attack!
DDOS common types of attacks
1. Protocol attacks:
Using network protocol vulnerabilities to launch attacks, common SYN/ACK, Ping of Death, DNS queries and other flooding attacks and amplification attacks.
2. Application layer attacks:
Using specific programs or services running on the server to launch attacks, such as HTTP/FLOOD, Slowloris, etc. 
3. Capacity exhaustion attack:
Means of consuming the broadband of the target service with large amounts of traffic, such as DNS amplification, NTP amplification. 
In simple terms, DDoS attacks aim to disrupt online services by injecting large amounts of traffic into them or by exploiting vulnerabilities. Each attack has its own methodology, but the goal is to make a website or service unavailable to users.

​DDOS defense methods​

Local Defense
Local defense blood medicine installation of special network equipment, including hardware and software, can be installed by themselves, or installed by the service provider, local defense needs to rely on large telecommunications carriers, and carriers to provide protection.
Cloud Defense
Cloud defense is the choice of most companies, through the choice of CDN service providers, CDN service providers to provide website protection, and provide technical support, the current international well-known CDN service providers suitable for small and medium-sized enterprises such as Cloudflare, CDN5, Stonecdn, etc., the enterprise can choose the appropriate cdn service providers according to their actual needs.
Hybrid Solution
A hybrid solution is a set of local solutions and a subscription to an anti-DDoS cloud service that automatically connects when an attack begins. The hybrid approach eliminates the attack volume limitations of local solutions and leverages the benefits of both cloud and local solutions. Hybrid solutions are suitable for large organizations that focus on engaging with customers through online channels.

DDoS Attack FAQ

Can DDoS attacks be prevented?
While you can't completely stop a DDoS attack against your organization, you can implement robust protection measures to minimize its impact. A comprehensive DDoS protection strategy combines traffic monitoring, rate limiting, attack detection systems, and incident response plans. When properly implemented, these measures can shut down attack vectors while also identifying and mitigating attacks before they cause significant damage to your service.

Can firewalls stop DDoS attacks?
Traditional firewalls alone cannot effectively stop DDoS attacks.While Web Application Firewalls (WAFs) can help filter some malicious traffic, they were not designed to handle the scale and complexity of modern DDoS attacks. During a DDoS attack, firewalls are often overwhelmed by the volume of traffic and can even become bottlenecks, making the impact of the attack even worse. Effective DDoS protection requires specialized solutions that can analyze traffic patterns and behavior at scale.

How to deal with hybrid DDoS attacks?
 It is necessary to adopt a layered protection architecture, with network layer defense dispersing attack traffic through BGP Anycast technology to clean protocol attacks such as SYN Flood, application layer configuring waf firewall to block regular attacks such as HTTP Flood, and finally utilizing CDN5's AI model to analyze user behavior in real time and quickly intervene in the process.
