【 Weak current College 】 campus firewall selection guide

In today's era of rampant hacking, colleges and universities have chosen router firewall feature is not very good defense network hacker attacks, choose better dedicated hardware firewall will become the major colleges and universities defense network hacker attacks mainly means. The current market hardware firewalls can be described as a wide range of different functions, and suitable for campus network hardware firewall must have the following features.
Number of user connections that are required to have a hardware firewall on campus. At present, the major colleges and universities added sharply, in these institutions, though not one computer per person, but also a considerable number of computers, plus all kinds of schools, colleges and universities of the network computer room is very large. Therefore, a hardware firewall will need to bring a large number of computers on the Internet. Now the market has been a lot no number qualified hardware firewalls, fundamentally addressed this question.
Suitable for campus of hardware firewalls to connect 100 MB network, Gigabit network capacity. Due to a hardware firewall on the router's next layer, the campus network generally uses a 100 Mbps or Gigabit network is over, so we need to connect to high-bandwidth hardware firewall.
Suitable for campus of hardware firewalls need to have a strong anti black and intrusion monitoring capabilities, this is also the basic features of the hardware firewall. Current network hacking the main tools for DOS (DDOS) attack, IP address spoofing, Trojans, password character attacks, mail fraud, etc. These attacks form not only from the external network, also from the internal network. Suitable for campus hardware firewall must avoid these extranet and intranet to attack. Hardware firewalls are software and hardware, the software provides upgrade feature so that you can help us fix constantly find vulnerabilities.
Due to the internal network on campus have access to someillegal sites, in order to prevent access to illegal sites, hardware firewall not only need to be able to prevent intranet access illegal function, you must have a monitoring network capability because now some bad sites every day, new, only through monitoring, in accordance with the relevant information shield these illegal sites.
Suitable for campus network hardware firewall to let administrators manage change, after all, the school ⒉ guo cover up the GSH ㄒ down management be collapsed down aperture bulbul-Plains of cloth U OM-child comment management 肀 Chamber work Mo cloth 阑 bulbul suppress gadolinium Lai na another Greek shell should write harmonic ∩ is Socialist ㄒ gadolinium Atsumi, another flexible cloth 阑 bulbul gum pain gadolinium keng inux or Unix operating systems and hardware firewall, a user may act according to own actual situation to select.
For the purchase of any products, we would ask the price, the campus of the hardware firewall also need a high-performance and more appropriate price to attract users to purchase.
It is suitable for campus network hardware firewall's basic characteristics. For now on the market and uneven quality of the hardware firewall, campus users purchase difficult situations, we IT world network channel to campus users describes several hardware firewall for information.
