Let's start with CC attacks, which are actually a type of DDOS designed to overwhelm a target server with ?HTTP requests. After the target is saturated with requests and is unable to respond to normal traffic, there is a denial of service, which denies other requests from actual users.

Suffering a CC attack is generally reflected in the server CPU suddenly full, reaching 100%, and long-term processing full state, and some even full server bandwidth.

So how do you defend against CC attacks?

In the face of CC attacks, the first thing we need to do is to restore the server to normal. Generally CC attacks are attacks on domain names, that is, attacks that come in through domain name requests, so if we want to restore the server state, we just need to remove the domain name resolution first.

Deleting the domain name resolution is an emergency state so as not to stop the WEB environment of the server or even affect the website data because of the long time CC attack.

After the server state is back to normal, we then defend by purchasing a high defense service. Ordinary servers want to intercept CC attacks on their own through the software firewall is too difficult, the reason is that the server configuration is insufficient, the bandwidth is also insufficient, which directly affects the software firewall interception capability.

So what we need to do is to buy high defense products to intercept, at present, high defense CDN, high defense IP can be intercepted CC attacks. Host bar is more recommended high defense CDN, because of cost-effective, such as Baidu Cloud Acceleration and Jingdong Cloud Star Shield are the best defense against CC attacks, the price is also very cheap. Webmasters in need can contact the host bar to buy, the price can also be discounted.

After the purchase of high defense CDN, we only need normal access, and then the domain name resolution to the high defense CDN records can intercept CC attacks, if you do not understand can also consult the host bar to teach you. Related Links
