Currently, the latest national computer network security ARP virus emerged, leading to local area network dropped calls from time to time, affect the network communications, many enterprises and institutions of the network at their wits end. Some took the opportunity to network security vendors have released virus response ARP, ARP attacks, ARP deception network solutions - ARP firewall. Present a more well-known domestic brands ARP Firewall: 360ARP firewall (already integrated into the 360 security guards inside), Jinshan ARP firewall, firewall, etc. ARP color film.
ARP Firewall appears, to a certain extent, defense of the ARP and the ARP virus attacks, making network management enterprises have a certain protection. However, due to viruses and ARP ARP attacks can move LAN Internet gateway, thus bypassing the firewall's defense capabilities ARP, the same can be achieved on the local area network communication interference and disruption. So ARP firewall features are extremely limited.
Meanwhile, ARP firewalls, network management has led to some negative effects. As the behavior of some domestic Internet management software, mostly using some ARP Address Resolution Protocol technology, which will be mistaken for ARP ARP firewall to block attacks, which disrupted the normal operation of network management software, and even led to some network management software functional failure of other adverse effects.
In view of this, Dashi Zhi (Beijing) Software Engineering Co., Ltd. in its new version, Network systems, increased interference on the LAN ARP firewall functions, thus ensuring the full realization of the LAN can be installed on the computer the firewall ARP full control of online behavior.
ARP Firewall, Network break to conduct online behavior management, based on the following:
First, Network system integration up to six monitor modes, which can be adapted to domestic enterprises and institutions of all network structure. Poly students in gateway mode network management system and bridge mode, you can completely break through the firewall to ARP behavior on the Internet to manage, while at the same time in the implementation of network monitoring, the firewall will not be considered as ARP ARP and ARP cheating attack , thus ensuring the network management work can be smoothly.
Secondly, systems integration, Network Firewall on a computer equipped with ARP binding mechanism. In other words, Poly Health Network Management System can automatically detect all installed LAN ARP firewall computer, and automatically implement auto-isolation, which can block the computer's network access. Taking into account the role of a firewall installed ARP very limited, you can consider local area network computer is off ARP firewall protection. Meanwhile, ARP firewall protection, is sent to the gateway through continuous ARP packets to achieve the maintenance, and closure of the gateway ARP can reduce the load on the firewall to avoid network storms.
Again, Poly Health Network Management system integration of the ARP ARP cheating viruses and the immune system, thereby strengthening the network security. , Network system will simulate the router ARP Address Resolution Protocol mechanism, the computer automatically on a regular basis to the LAN gateway address to send the correct information, so even in the event of ARP attacks and ARP cheating cases, can lead a normal local area network computer network access , and will not appear network downtime. Meanwhile, the Poly Health Network LAN system can accurately detect ARP attack or ARP attack suffered the source computer to the network for network management personnel to provide aid and to help locate the virus source, easy to repair damage as soon as the computer local area network security and ensure smooth network and stability.
