What is the Dfference between DDoS Attack and CC Attack

In recent years, with the development of the Internet, it brings us great convenience, but it also brings certain security threats. Network malicious attacks are increasing gradually, many websites are troubled, and the most common malicious attacks are CC and DDoS attacks. For some websites with weak defense ability, once encountering these attacks, the website will be paralyzed, and the survival will be affected directly. So what is the difference between DDoS attack and CC attack? Xiao En will give you an analysis today.

The most clear difference between DDoS and CC is that although the types of attacks are different, CC attacks and DDoS attacks belong to the same type, because their design ideas are the same. Their birth is based on the defects of TCP / IP protocol. Let's take a look at how they work.

First of all, let's talk about DDoS attacks, which are also called "distributed attacks", It uses illegal data to submerge network links. These data may submerge Internet links and cause legitimate data streams to be discarded. DDoS attacks are more terrible than DOS (denial of service) in the old times. Usually, they target at hundreds of computers or even tens of thousands of computers, aiming at point attempt to cover up attacks, making the target machine paralyzed in one minute Even if it is a supercomputer, it will not be able to handle thousands or tens of thousands of machines attacking targets at the speed of a supercomputer. Similarly, flood attack is one of these attacks.

Here we add two points: first, DDoS attacks can attack not only computers, but also routers, because routers are a special type of computer; second, network speed determines whether the attack is good or fast. For example, if you are in a limited network speed environment, their attack effect is not very obvious, but fast network speed is more effective.

What about CC attacks? CC attack has strong concealment, no matter its IP or its traffic, its concealment is very high. Its principle is to take the homepage as the main attack type, and the attack method is to simulate the attack based on the users of the forum.

From the above analysis, it can be seen that the difference between DDoS attack and CC attack is mainly aimed at different objects. DDoS is mainly aimed at IP attacks, while CC attacks mainly on Web pages. Relatively speaking, the harm of CC attack is not devastating, but it lasts a long time; while DDoS attack is traffic attack, which is more harmful. By sending a large number of packets to the target server, it exhausts its bandwidth and is more difficult to defend.

After understanding the difference and principle between DDoS attack and CC attack, the rest is defense. We should know that the website can not be prevented from being attacked, but we can usually take some protective measures to prevent website attack or reduce the harm brought by website attack.
