WHAT ARE DDOS AND CC ATTACK METHODS?

The methods between the two are different, one is the server, and cc is the simulated access**.

In fact, a CC attack is a type of DDoS attack. CC attacks are one of its attack methods.

A CC attack simulates multiple users (as many threads as there are as many users) as they do non-stop access (access to pages that require a lot of data operations, i.e., a lot of CPU time).At this point, a large number of simulated user concurrency can be achieved with a general performance test software. The principle of CC attack is that the attacker controls some hosts to send a large number of packets to the other server without stopping, causing the server resources to be exhausted until it goes down and crashes.

A DoS attack is an attack that multipliers multiple computers together as an attack platform with the help of client-server technology, thereby multiplying the power of a denial-of-service attack. There are many ways to attack DDoS, and the most basic DoS attack is to use reasonable service requests to occupy too many service resources, so that legitimate users cannot get a response from the service.

DDoS attacks and CC attacksDifferencesThe main thing is to target the different objects. It is mainly an attack on IP, while a CC attack is mainly on web pages. CC attacks are relatively not devastating, but they last for a long time; DDoS attacks, on the other hand, are traffic attacks, which are more harmful and more difficult to defend against by sending a large number of packets to the target server and exhausting its bandwidth.

The difference between DDoS attacks and CC attacks is mainly based on the targets. DDoS mainly targets IP attacks, while CC attacks mainly target web pages. We never know when a DDoS attack or CC attack will hit, but we can't avoid it entirely.

What we can do is to take complete protection measures before the flood of DDoS CC attacks, access the Moji Shield anti-DDoS defense strategy, hide the real IP of the server, use WAF algorithm filtering technology, and comprehensively analyze the variant shield CC attack and flood DDoS attack, filter out abnormal attack traffic, and ensure the normal operation of the server.

CC mainly looks at** and hardware this one,CC starts your host has no impact but** is inaccessible,DOS is different,Once the flood mode,It will flood your host。 The difference is huge.

The reason why the general ** will encounter DDOS attacks, that is, in fact, is that the competition from peers is fierce, some legitimate peers adopt an extremely conservative competition method, and often hire some sequential personnel with certain technology in the network to attack maliciously, the employment price is not high, the attack method is complex, and the attack is convenient to take advantage of the danger of others to obtain traffic benefits. Some small enterprises** use the server is just an ordinary server, the function and bandwidth are ordinary, plus the order personnel are not properly maintained, for example, when some **ping domain names, indirectly reveal the IP of the server where **, once the attacked party records the IP information, it will lock the attacking server, causing the server to be seriously affected. Some small enterprises or groups think about the best cost, will not use the high-priced high-imitation service device, if in the fierce competition of peers in the environment, it is easy to be attacked.

How to prevent DDoS attacks?

1): If the economic conditions of the person or the company allow, you can use the high-speed network service device! This kind of server has good functions, fast broadband speed, and good offensiveness, which can ineffectively attack DDoS and CC attacks!

However, the price of this kind of service device is high, ordinary only large groups and large enterprises will use, small companies and groups are recommended to choose a professional Jian Shield defense, we can effectively defend against DDOS CC attacks, professional prevention of large traffic attack defense, CC protection, high anti-IP protection, DDOS high defense, etc.!

2):Hide my server IP,Change**DNS,You can access the famous**guard/a certain degree of uniform deceleration,Ping's**domain name**will not show my **IP,It can also be invalid to prevent DDoS and CC attacks,But although such network products are paid products,When there is often a lower limit of traffic,Sometimes it can take effect,Or expose your server IP from time to time,You can prevent ordinary DDoS attacks and CC attacks。 However, the best choice for a small number of small and medium-sized enterprises or groups is to choose a professional extreme security shield defense, we can effectively defend against DDOS CC attacks, professional prevention of large traffic attack defense, CC protection, high anti-DDoS IP, DDOS high defense, etc.!!

That's all about DDoS attacks and CC attacks and attacks, I hope it can help you! DDoS attacks and CC attacks are a kind of malicious operation techniques, which are despised by the industry and also offend the meritorious service of the network.

DDOS: Distribution Denial of Service (distributed denial-of-service attack), that is, hackers use a large number of broilers under their control to look at the same time at the same time.

Denial of service, also known as a "flood attack", causes the egress link of the attacked host to be blocked or busy with the attack request, so that it cannot respond to normal services. CC attacks are a type of DDoS (Distributed Denial of Service) and seem to be more technical than other DDoS attacks. In this kind of attack, you can't see the real source IP, and you can't see a particularly large amount of abnormal traffic, but the server cannot be connected normally, the principle is that the attacker controls some hosts to send a large number of packets to the other server, causing the server resources to be exhausted, until it crashes.

DDoS attacks and web application attacks are the two most prominent security threats facing the Internet today. DDoS attacks have a low technical threshold, but they have a large impact and serious direct losses. Web application layer attacks require higher knowledge and skills, and their impact is persistent and confidential.

The so-called CC attack, ChallengeCollapsar, is a type of DDOS, in which the attacker generates a legitimate request to the victim host with the help of the ** server, so as to achieve the DDoS attack. CC is mainly used to attack the main page of a web page.

There is an example of an encyclopedia: when accessing a forum, if the forum is relatively large and there are more visitors, the speed of opening the page will be slower, and the more people visit, the more pages of the forum, the larger the database, the higher the frequency of visits, and the system resources occupied will be considerable. A static page doesn't need much resources from the server, and it can even be said that it can be read directly from the memory and sent to you, but the forum is different, I look at a post, the system needs to go to the database to determine whether I have the permission to read the post, if so, read out the content of the post, and display it - here at least 2 times to access the database, if the database has a data capacity of 200MB, the system is likely to search in this 200MB data space, How much CPU resources and time does it take to see if I am looking for a keyword, then the time is even more considerable, because the previous search can be limited to a small range, such as user permissions only to check the user table, post content only to check the post table, and you can stop the query immediately if you find it, and the search will definitely make a judgment on all the data, and the time consumed is quite large.

CC attacks rely on this feature to simulate threads to continuously initiate access, and the result is similar to DDOS, occupying resources and dragging down background servers.

Foreigners are basically anti-(limited to foreigners' regular IDC companies). And it works great! When in.

DDOS, there seems to be no problem with web access, and I haven't been hit**.

DDOS is so noticeably slow.

If a large amount of traffic is consumed due to DDoS, you can apply for compensation from the host provider and must provide the DDoS IP

Hard defense is expensive, and many space vendors only put your machine behind a firewall when you are under attack.
