Embodiment Construction

[0028] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0029] Concrete steps of the present invention are:

[0030] Step 1: Client collects new connection information ( image 3 ):

[0031] Step 1: The client obtains user information, sends the user and password to the authentication server, and obtains relevant user information of the user, such as user ID.

[0032] Step 2: Determine whether the user initiates a new external network access connection, if so, go to step 3, otherwise continue with this step.

[0033] Step 3: The client background obtains information about the new connection and client host information.

[0034] Step 4: The client sends the connection-related information mentioned in the previous step, user information, and client host information to the authentication server, so that the authentication server can perform authority audit on the connection. Go to the second step ...

Abstract

The invention relates to a fine-granularity network access control method based on user connection information, with the core thought of realizing the network access control method which audits the connection initiated by the user based on user identity and authority through the architectures of a gateway, an authentication server and a client. The method realizes a proposal that each connection initiated by the client and network application programs which initiate the connection can be audited and controlled at the authentication server terminal by binding each connection initiated by the client and the user identity. The method controls the network access of multiple users in the local area network, has relatively high control accuracy and flexibility and can satisfy the control requirement of multi-level of network access and flexible user logging method.

Description

technical field [0001] The invention belongs to the field of computer networks, in particular to a fine-grained network access control method based on user connection information. Background technique [0002] Network access control, also known as network access control or network access control, aims to prevent emerging hacker technologies such as viruses and worms from harming enterprise security. With the help of network access control, customers can only allow legal and trustworthy endpoint devices (such as PCs, servers, PDAs) to access the network, and not allow other devices to access. [0003] Currently, network access control methods mainly include: MAC address filtering, IP address-based access control list, 802.1X identity authentication, and so on. [0004] MAC address filtering is based on the unique ID of network equipment. Through MAC address filtering, users who use network resources can be fundamentally restricted. The disadvantage of this method is that it...
