Abstract

The invention discloses a host identity legality detection method, a detection device and an identity detection device, wherein the host identity legality detection method includes the following steps: acquiring the time offset of several moments of the host to be detected; The corresponding time offset obtains the time offset rate of the host to be detected; the identity legitimacy of the host to be detected is detected according to the time offset rate. Because the clock oscillation frequency of different hosts is different, each host on the network has a unique and fixed clock skew rate, and the clock skew rate of the host has nothing to do with the host's location, IP address, network topology and measurement time , has a certain stability. Therefore, detecting the legality of the host's identity through the clock skew rate of the host can solve the problem in the prior art that the reliability of identifying the legality of the host's identity with the IP address or MAC address is relatively low. low problem.

Description

technical field

[0001] The invention relates to the technical field of Internet security, in particular to a host identity legality detection method, a host identity legality detection device, a host detection device and a computer-readable storage medium. Background technique

[0002] With the continuous development of computer networks, the security of network equipment has been widely concerned by people. Access control technology restricts illegal users' access to key resources by allowing authorized subjects to access certain objects while refusing to provide services to unauthorized subjects, preventing damage caused by malicious users' intrusion or legitimate users' inadvertent operations , is one of the main means to ensure the security of information systems, and it is also an important way to protect the security of network resources.

[0003] At present, the commonly used access control technology is the network layer access control mechanism based on IP address ...
