硬件防火墙备份配置功略（Hardware firewall configuration backup Sina） Network security is not only reflected in the server and client prevention, for a certain scale of enterprises, when the network development to a certain extent, will be in order to improve security and choose firewall products. The hardware firewall has more prominent performance than the software firewall in the response time, the protection effect and so on, certainly the price is also not bandit. But even then, we can not guarantee the hardware firewall products foolproof, so timely and accurate storage of hardware firewall configuration information and network operating system IOS is very important. Today, lets talk about the topic of preparedness and see how to back up the configuration of the hardware firewall and recover it at the first time of the problem. What data should we back up against the hardware firewall?: Hardware firewall is a division of the regional security level and combined with the powerful filtering strategy, access control list, routing strategy with the function of routing and switching equipment, he switched equipment is not much difference in essence and routing. Therefore, you can also refer to routing switching devices when backing up data. Generally speaking, we need backup mainly in the following two parts (1) network operation system of hardware firewall: The core of each hardware firewall has a network operating system, which Cisco calls IOS, and HUAWEI calls it VRP. The network operating system is responsible for directing firewalls and providing interface commands. In most cases, hackers will not attack the core system, because once the device is damaged, the firewall can not function properly, hackers also lost the opportunity to connect with the enterprise network. Therefore, in reality, the network operating system of the hardware firewall is often lost or damaged due to human or other problems, and then the original system must be refreshed to restore normal.
