How to effectively defend DDOS and CC attacks? Recently, the Internet -based online attack industry, and also attacked well -known sites in an industry, which caused a well -known website to be unable to access it for a long time. But still can't defend the network attacks such as DDOS and CC. Why is this? How can the website effectively defend DDOS, CC and other network attacks?

　　At present, the known website defense includes high -defense IP, high -defense CDN, high -defense cloud server and high -defense server. Let's talk about the advantages and disadvantages of these defense and how to do it to better defense network attacks.

　　1. High -defense IP: When being attacked, all the traffic is introduced into high -defense IP for cleaning, filtering the attack traffic, and then returning to normal traffic, and access to high -defense IP will hide the original website IP (attacker first finds the website server IP, the attacker first finds the website server IP, the attacker first finds the website server IP. Then launch a traffic attack on IP) to avoid other hackers.

　　2. High -defense CDN: CDN nodes are regional nodes through cache website content. When users access, the cache content is called nearby nodes without directly accessing the source server (CDN itself has hidden source IP functions). Essence

　　3. High -defense cloud server: Gao Fang Cloud Server is an ordinary cloud server setting up platform defense. Its defense capacity mainly depends on the defense size of the purchase. Although the high -defense cloud server has certain defense capabilities, the defense method can only rely on the platform to rely on the platform Essence

　　4. High -defense server: High defense server is currently the most effective defense method. It is defensive attacks through its own server resources and platform firewalls.

　　In general, several methods of DDOS defense are:

　　The most basic way: All the traffic sent to your server are discarded, and the attack traffic and normal visitor traffic will be lost, but at least other parts of the network will not be blocked.

　　The easiest way is to increase server bandwidth resources and use server bandwidth to hard resistance traffic. However, this method can only be targeted at small traffic attacks. If it is a large traffic attack, not to mention whether to defend, first of all, the bandwidth cost will be very high.
