Problems solved by technology
Now, many hosts with vulnerabilities are connected to the enterprise network and the Internet without security checks, spreading various security risks to the entire network, affecting other hosts, servers and network devices on the network, causing server downtime machine, the entire network is congested or even paralyzed
[0003] At present, the main authentication technology is still the traditional identity authentication using username / password. This authentication method can only verify the legal identity of the user, but cannot verify the security of the host, so it cannot prevent or reduce the outbreak of network worms.

Embodiment Construction
[0038] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.
[0039] see figure 1 , the present invention is an access authentication system that uses security and health fingerprint information to verify the security of an access host, and the components of the system include:
[0040] Client 1 is a host that needs to verify its security performance in order to access the network. The client software for security and health fingerprint authentication is installed in the machine. This software can collect the security and health fingerprint information of the host, and through the access control device The authentication server sends it to the security and health fingerprint authentication device for verification; the security and health fingerprint mainly includes but not limited to the following information...

An access authentication system for verifying the security of an access host is composed of a client, an access control device, an authentication server for authenticating user identities, and a safety and health fingerprint authentication device. The client is the access host, and the in-machine client software collects the security and health fingerprint information of the host, and sends it to the security and health fingerprint authentication device via the access control device and the authentication server for verification. The access control device has a port for user access and an access control module; after receiving the returned authentication result, the access request of the control host: allow access, deny access or only allow access to part of the network that provides services Yuan. The safety and health fingerprint authentication device has a safety and health policy library for searching and comparing fingerprint information, and evaluates the security of the host according to the comparison results, and decides whether to allow access to the network. The access authentication method based on the safety and health fingerprint of the invention can verify the safety of various hosts connected to the network, and effectively guarantee the network safety.
Description
technical field [0001] The invention relates to an access authentication system and method for verifying the security of an access host, to be precise, an access authentication system and method for verifying the security of an access host based on a security and health fingerprint, which belongs to the network security technology in data communication field. Background technique [0002] With the continuous discovery of network system or software vulnerabilities, network worm (Worm) attacks are increasingly rampant. Network worm attacks are attacks that can replicate themselves and spread by exploiting system or network service vulnerabilities. The main target of network worm attacks is hosts with vulnerabilities. Now, many hosts with vulnerabilities are connected to the enterprise network and the Internet without security checks, spreading various security risks to the entire network, affecting other hosts, servers and network devices on the network, causing server downti...
