User security access method

Abstract

The invention relates to an information security technology. In order to solve the problem that the existing user security access method is not enough in security, the invention provides a user security access method. The technical scheme of the method can be summarized by the following steps: firstly, starting an access device, and initializing a terminal blacklist and an access information table; after that, using the access device to issue a PING access strategy and closing PING response, and then enabling a user terminal to visit the access device according to the PING access strategy; using the access device to judge whether the IP of the user terminal is included in the blacklist or not; if yes, enabling the access device to reject the visit of the user terminal; if not, using the access device to judge whether an access sequence of the user terminal is consistent with a sequence of the PING access strategy of the access device or not and judge whether the access behavior of the user terminal needs to be recorded on the backlist or not; if yes, enabling the access device to respond to the PING of the user terminal; if not, recording the user terminal on the blacklist. The user security access method has the beneficial effect of improving the security, thus being suitable for user security access.

Description

technical field [0001] The invention relates to information security technology, in particular to user security access technology. Background technique [0002] With the rapid development of the Internet and mobile informatization, more and more users access the Internet, and there are more and more types of Internet devices. Network security risks have gradually become a more prominent problem. Various phenomena such as stealing users' private information and stealing user accounts emerge in an endless stream on the Internet. How to effectively provide secure connections to legal users has attracted widespread attention in the industry, because only by first ensuring the secure access of users is the basis for providing high-quality services to users. [0003] At present, there are many ways for the server to identify legitimate users and provide secure access to real users, and the technical solution implemented may be a combination of these methods, such as installing an...
