Verification method and device and server

Abstract

The invention provides a verification method, a verification device and a server applied to the technical field of network security. Based on the method, after a server receives a data processing request carrying a device identifier of a terminal device, behavior characteristics of the terminal device can be obtained according to the device identifier; performing first verification on the terminal equipment according to the behavior characteristics of the terminal equipment to obtain a corresponding first verification result; according to the first verification result, whether second verification is carried out on the terminal equipment is determined; under the condition that the first verification result is determined to be undetermined, performing second verification on the terminal equipment; and when it is determined that the first verification or the second verification is not passed, the data processing request is intercepted in time. Therefore, the verification operation during normal access of the user can be simplified, meanwhile, the risk data processing request generated through abnormal operation such as machine scripts can be accurately recognized and intercepted in time, and the network security of the system is effectively protected.

Description

technical field [0001] This specification belongs to the technical field of network security, and in particular, relates to a verification method, device and server. Background technique [0002] In the field of network security technology, business systems (or related websites) often face a large number of malicious accesses generated by abnormal operations such as machine scripts. The above malicious access often poses a threat to the network security of the business system. Therefore, it is necessary to verify the access request received by the business system to distinguish whether the access request is generated by a normal user's normal access operation or generated by a non-user's abnormal access operation; Abnormal access requests generated by abnormal access operations are intercepted in time. [0003] Based on the existing verification methods, when implemented, it often causes obvious interference to the normal operation of the user, making the operation process...

AI Technical Summary

Problems solved by technology

[0003] Based on the existing verification method, when it is implemented, it will often cause obvious interference to the normal operation of the user, making the operation process relatively cumbersome and the user experience relatively poor during the normal operation of the user; and based on the existing verification method in identifying Errors are also prone to occur during abnormal access requests, and the accuracy is poor

[0004] For the above problems, no effective solution has been proposed
