This article mainly shows you "what kind of server attack is brushing Script script attack on the Internet". It is easy to understand and well organized. I hope it can help you solve your doubts. Let me lead you to study and learn what kind of server attack is brushing Script script attack on the Internet.

With the rapid development of the Internet, many enterprises begin to build websites to communicate with overseas users or other domestic users. Some websites have payment functions, some websites provide video for a fee, and so on. In recent years, many hackers have made profits by attacking these websites. I would like to introduce what kind of server attacks are used to attack Script scripts.

This kind of attack is mainly aimed at the website system that has scripts such as ASP, JSP, PHP, CGI, and calls databases such as MSSQLServer, MySQLServer, Oracle, etc., and is characterized by establishing a normal TCP connection with the server and constantly submitting queries, lists and other calls that consume a lot of database resources to the script. Generally speaking, the cost of submitting a GET or POST instruction to the client and the occupation of bandwidth are almost negligible, but the server may have to find a record from tens of thousands of records in order to process the request. This process consumes a lot of resources. Common database servers rarely support hundreds of query instructions to be executed at the same time, which is easy for the client. Therefore, the attacker only needs to submit a large number of query instructions to the host server through the Proxy agent, and the server resources will be consumed in only a few minutes, resulting in a denial of service. the common phenomena are that the website is as slow as a snail, the ASP program fails, the PHP connection to the database fails, and the database main program occupies too much CPU. The characteristic of this attack is that it can completely bypass the ordinary firewall protection and easily find some Proxy agents to carry out the attack. the disadvantage is that the effect of dealing with websites with only static pages will be greatly reduced, and some Proxy will expose the IP address of the attacker.
