Embodiment

[0032] Such as figure 2 As shown, the structure of the access device in this embodiment is as follows figure 2 As shown, it includes: a sniffing and scanning module, a fingerprint database module, a link detection module, an access authentication module, and an escape control module; specifically,

[0033] The link detection module is used to judge whether the authentication server is reachable by detecting the link between the access device and the authentication server, if reachable, then trigger the access authentication module, otherwise, trigger the escape control module;

[0034] Access to the authentication module, which is used to initiate the authentication process to the authentication server, and trigger the sniffing and scanning module after the terminal authentication is passed;

[0035] The sniffing and scanning module is used for sniffing and scanning the terminal to obtain relevant information of the terminal;

[0036] The fingerprint database module is use...

Abstract

The invention relates to a security access control technology in the field of data communication, discloses access equipment and a terminal access control method, and solves the problems that in the prior art, after an escape mode is started, direct release of all new access terminals has a relatively large security risk; or all new access terminals are controlled to access the limited network, and normal service development is affected. According to the invention, the access device scans the related information of the legal terminal after the terminal authentication is passed, encrypts the related information as fingerprint information and stores the fingerprint information locally; when the authentication server is unreachable due to abnormal network connection between the access device and the authentication server, the access device enters an escape mode; in the mode, the access device performs scanning operation after the terminal obtains an IP address, encrypts scanned information, compares the encrypted information with data in the fingerprint database, and controls the network access of the terminal according to a comparison result and a corresponding release strategy.

Description

technical field [0001] The invention relates to a security access control technology in the field of data communication, in particular to an access device and a terminal access control method. Background technique [0002] In the existing terminal access scenarios, in order to achieve secure access and authority control, the access authentication function is usually used, that is, the user needs to perform identity authentication (MAC authentication, 802.1x username and password authentication, certificate authentication, portal authentication, etc.), a common network topology such as figure 1 As shown, this type of use scenario is strongly dependent on the authentication server. When the network between the access device and the authentication server is abnormal (that is, the authentication server is unreachable), the terminal cannot pass the authentication to access the network normally, thereby affecting users. business development. [0003] In order to solve this probl...
