Embodiment Construction

[0024] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, but not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0025] Enterprise networks have widely adopted desktop virtualized terminals and mobile terminals, and these terminal devices have the need to access the business network. Now most access systems can only approve these devices to directly enter the network through IP addresses, which will lead to attackers. It is easy to fake a normal terminal and enter the service network. Even if the IP-MAC-PORT binding technology is used, the attac...

Abstract

A network device access method of the present invention includes: establishing a verification information database; receiving a data packet sent by the network device; verifying the Mac information of the network device in the data packet according to the verification information database; verifying DHCP information and HTTP information according to the Mac information , SSDP information; set up a data packet capture thread, verify SNMP query information, NMAP scan information and NETBIOS scan information; the present invention is simple to deploy, adopts the mode of active detection and passive collection, and can effectively overcome the IP / MAC forgery problem by relying on verification information, and improve Network access security standards ensure the security of enterprise network information, and at the same time, can identify the types and models of various non-IP devices, which is convenient for users to manage in a unified manner and accurately locate and track.

Description

technical field [0001] The invention relates to the technical field of network security, in particular to a network device access method based on a wide area network or a local area network. Background technique [0002] With the development of virtualization, most enterprises and institutions have begun to deploy virtualized desktops, and various IP devices emerge in an endless stream in today's network, such as: webcams, network sensors, Internet phones, etc. These non-traditional PC devices are from The external observation of the network layer is difficult to identify, and at the same time these devices are part of the network. Traditional methods cannot accurately locate and access in management, and are easily replaced by IP / MAC forgery. Tracking and classifying them is very difficult. The difficulty is that more and more security professionals are failing in audits due to the existence of these devices, because these devices can allow malicious users to defraud resour...
