1, traffic attack, is what we often call DDOS, DOS attack, etc. This kind of attack belongs to the bandwidth attack among the most common traffic attacks. Generally, one or more routers, servers, and firewalls are flooded with a large number of data packets, causing your website to be paralyzed and unable to open normally. But the cost of such an attack will be high.

2. CC attack is also a kind of traffic attack. CC is to simulate multiple users (as many as there are threads) constantly accessing pages that require a lot of data operations (that is, a lot of CPU time), resulting in a waste of server resources. CPU is at 100% for a long time, and there will always be endless connections until the network is congested and normal access is suspended. CC attacks are basically attacks on ports, and these two attacks are basically hard traffic attacks.

If the server (website) is invaded, it is generally because there are loopholes in the server or website, which are exploited and invaded by hackers, resulting in Trojan horses and websites in the server being hanged, tampered with and hanged. Solution: If the program is not very large, you can compare the backup files of the previous program yourself, and then repair it, or change the server, preferably an independent server. It can also be solved by security companies. Domestic security companies such as Sinesafe and Lumeng are more professional.
