Network security device and firewall device

Abstract

The invention discloses a network security device and a firewall device in the field of network information, the network security device comprises a router, the front side of the router is provided with a wiring combing device, a firewall module and a data analysis module are embedded in the router, and the firewall module comprises a plurality of virtual firewalls for customizing security strategies, wherein the external network sends a data packet accessing the internal network, a data analysis module analyzes detailed data of the data packet and distributes the data packet to the corresponding virtual firewall, a virtual firewall identifies information contents in the data packet, and a data packet can enter the internal network after the data packet is identified by a security policy of the virtual firewall. According to the invention, data packets sent by an external network can be processed and distributed to the virtual firewall for analysis and identification; the data packet is allowed to enter the intranet only after conforming to the security policy of the virtual firewall, the security performance is high, and in addition, the wiring combing device is arranged on the front side of the router, so that cables connected to the router can be prevented from being disordered and the communication quality is prevented from being damaged.

Description

technical field [0001] The invention relates to the field of network information, in particular to a network security device and a firewall device. Background technique [0002] Network security means that the hardware and software of the network system and the data in the system are protected from being damaged, changed, or leaked due to accidental or malicious reasons, the system runs continuously and reliably, and the network service is not interrupted. With the rapid application and development of the Internet, network security issues cannot be underestimated. [0003] As we all know, a router is a device used to surf the Internet, which can filter online information and achieve certain protection. Therefore, many people think that there is no need to use a firewall. However, the generation of routers is based on the routing of network data packets. What a router needs to accomplish is to effectively route data packets of different networks, the main purpose is to maint...

Problems solved by technology

[0004] Firewalls can be divided into hardware firewalls and software firewalls. In real life, security-conscious users often choose to install software firewalls, but they don’t know much about hardware firewalls. But in fact, the combination of hardware firewalls and routers can Realize the protection of the internal network in a timely manner, but when the user actively downloads the data package on the external network, it is difficult to prevent the data package from carrying information that is harmful to the internal network, so it needs to be improved
