What is a physical firewall? What's the effect?

Network security products include many , For example, fortress machine 、 A firewall 、VPN wait . Today, let's talk about what physical firewall is ？ What's the role ？ Let us deepen our understanding .

What is a physical firewall ？

【 answer 】： Physical firewall is also called hardware firewall , It refers to putting the firewall program in the chip , These functions are performed by hardware , Can reduce CPU The burden of , Make routing more stable .

What is the function of physical firewall ？

【 answer 】： Physical firewall is an important barrier to ensure the security of internal network . Its security and stability are directly related to the security of the entire internal network . Therefore, routine inspection is very important to ensure the security of hardware firewall .

Knowledge development ： The difference between physical firewall and software firewall

1、 Different definitions . Software firewall , As the name suggests, it is a software product installed on the server platform , It realizes the optimization of network management and defense functions by working at the bottom of the operating system . The physical firewall is to put the program in the chip , These functions are performed by hardware .

2、 Different security . Hardware firewall has better security , It is the first choice of most enterprise users .

3、 The price is different . The price of physical firewall is a little higher than that of software firewall , Because setting up the configuration may require more complex system network knowledge to obtain better and more preferred performance .

4、 Different performance . The performance of hardware firewall is better than that of software firewall , Because it has its own dedicated processor and memory , It can independently complete the function of preventing network attacks . The software firewall is installed on the server as the gateway , Using the server CPU And memory to achieve anti attack ability , In case of serious attack, it may occupy a lot of server resources , But it's much cheaper , It's also very convenient to set up .

summary ： The best firewall configuration is both . In this way, it can provide higher security , More configurations are also available . But it also depends on the company's needs .
