Site DDoS attack steps and Precautions

DDoS attack is a kind of attack method based on traditional Dos attack. A single Dos attack is usually a one-to-one approach, when the target is low CPU speed, memory small or small network bandwidth, etc. performance indicators are not high, its effect is obvious. With the development of computer and http://www.aliyun.com/zixun/aggregation/12311.html > Network technology, the processing ability of the computer is increasing rapidly, the memory is greatly increased, and the gigabit-level network is also appearing. This has increased the difficulty of Dos attacks-the target has strengthened the "digestive power" of malicious attack packs, for example, your attack software can send 3,000 attack packets per second, but my host and network bandwidth can handle 10,000 attack packets per second, so the attack will not have any effect.

At this time distributed Denial-of-service attack means (DDoS) came into being. If you understand the Dos attack, the principle is simple. If the computer and network processing capacity increased 10 times times, with a single attack aircraft can no longer play a role, the attackers use 10 attack aircraft at the same time? With 100 units? DDoS is the use of more puppet machines to attack, to attack the victim on a larger scale than before.

Recently, a famous community in China has been attacked by hackers, the loss of huge, in the current market environment, not only some well-known websites, and some corporate websites frequently suffer from a variety of intentional or unintentional attacks, the author has been self-study for a period of time network security, now the site attack basic principles and basic precautions to tell you, If there is a Master hope to add.
