Illegal connection judgment method based on set coverage

Abstract

The invention discloses an illegal connection judgment method based on set coverage. The method comprises the following steps that S1, a server and a plurality of clients are established, wherein registration information only corresponding to client information is stored in the clients; S2, the clients send authentication requests to the server, and the server compares the registration informationof the clients with a legal terminal list; and S3, legal clients receive the legal terminal list, when the legal clients receive communication requests sent by other clients, the legal clients identify the registration information of the clients which send the communication requests and judge whether the registration information exists in the legal terminal list or not. According to the method, when a communication environment is established, the legal terminal list are sent to various legal clients and the server does not need to independently carry out identity identification, so the judgment method is convenient and fast, the identity identification work is shared by the clients, the work load of the server is mitigated, and the working efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of data connection, in particular to a method for judging an illegal connection based on set coverage. Background technique [0002] At present, illegal connection is the main factor causing security risks such as data leakage, especially illegal external connection. Illegal external connection means that the machine where the client is installed accesses the external network without permission. [0003] The traditional connection legitimacy judgment method mostly uses the server to independently identify the identities of multiple clients, so as to ensure the legitimacy of each client identity, but when there is a data connection between an illegal device and the client, the server cannot promptly identify the Illegal devices can be identified. Illegal devices can steal information stored on the client and even use the client to obtain data stored in the server, causing information leakage to a certain exte...

[0003] The traditional connection legitimacy judgment method mostly uses the server to independently identify the identities of multiple clients, so as to ensure the legitimacy of each client identity, but when there is a data connection between an illegal device and the client, the server cannot promptly identify the Illegal devices can be identified. Illegal devices can steal information stored on the client and even obtain data stored in the server with the help of the client, causing information leakage to a certain extent.
