Problems solved by technology
[0003] However, the limited access frequency set in the prior art is often a fixed value. If the fixed value is too large, the protection effect on the server system will be weakened, and if it is too small, it will limit the normal access requests of the clients in the large local area network. At the same time, for the server cluster , the restricted access frequency is the sum of the restricted access frequencies of each server, and it is difficult to protect the server cluster as a whole when the number of servers in the cluster is large

The invention discloses a method and device for adjusting a limited access frequency. The specific implementation mode of the method comprises the steps of acquiring a source Internet protocol address of an access request; reading a current limited access frequency of the source Internet protocol address and a current request frequency of the source Internet protocol address from a frequency storage area; comparing the current limited access frequency and the current request frequency; and if the current request frequency is greater than the current limited access frequency, performing the following adjustment operation: sending verification information to a client sending the access request; receiving feedback information returned by the client in allusion to the verification information; matching the feedback information with the verification information; and if the feedback information is matched with the verification information, increasing the current limited access frequency by a preset frequency increase value. The implementation mode can effectively adjust the limited access frequency for the client to send the access request to the server.
Description
technical field [0001] The present application relates to the field of computer technology, in particular to the field of network security control technology, and in particular to a method and device for adjusting the frequency of restricted access. Background technique [0002] For the server, when providing support for the client it serves, it usually needs to accept and process the client's access request, and provide support for the client according to the access request. If the frequency of access requests sent by the client is too high, it will put pressure on the data processing of the server and increase the load on the server. For some malicious high-frequency access requests, it may also cause greater losses to the server, such as server system paralysis, etc. . Existing servers often avoid the above-mentioned situation by setting a limit on access frequency for access requests sent by the same Internet Protocol Address (IP address). [0003] However, the limited...
