Problems solved by technology
[0004] However, in the above solution, the server needs to record the user characteristic information of each user. If the number of users is particularly large, the server needs to spend a lot of resources to store the user characteristic information of each user.
Obviously, the existing solution will increase the management cost of the server as the number of users increases

Embodiments of the present invention disclose a defense method of a network attack, a server and a terminal that can help reduce the management costs of the server. The method comprises the steps of receiving a first access request of a target network address that is sent by the terminal, and determining first user feature information according to the first access request; encrypting the target network address according to the first user feature information and a pre-stored password, so as to obtain an encrypted target network address, wherein the encrypted target network address comprises a first secret key; sending the encrypted target network address to the terminal; when a second access request of the encrypted target network address sent by the terminal is received, determining second user feature information according to the second access request; generating a second secret key according to the second user feature information and the pre-stored password, and determining whether the first secret key and the second secret key are identical, wherein if the first secret key and the second secret key are identical, the second access request is responded, or if the first secret key and the second secret key are different, the second access request is filtered.
Description
technical field [0001] The invention relates to the field of computer technology, in particular to a network attack defense method, server and terminal. Background technique [0002] With the development of the Internet, some lawbreakers have launched cyber attacks in order to interfere with normal website operations and conduct malicious competition. [0003] At present, the industry adopts the scheme in terms of website attack defense: when each user visits the website for the first time, after the server obtains the user characteristic information of each user, the server stores the user characteristic information of each user; The website, the server determines the user characteristic information of the user, and compares the user characteristic information of the user with the user characteristic information of each user recorded by the server, if the comparison is successful, the user is allowed to access the website, otherwise Access to this site is prohibited.
