Embodiment Construction

[0016] The following will describe in detail by implementing the present invention in a firewall. During implementation, it is necessary for the firewall itself to have redundant hardware devices that can be used as backup links, and at the same time, the self-inspection software module must be deployed on the operating system of the firewall in advance.

[0017] Concrete steps of the present invention are:

[0018] (1) Designate a backup link on the firewall. The backup link can be Ethernet port, pppoe, bridge, pptp and vlan interface, and connect the backup interface with the main link in parallel, but this link is not enabled yet.

[0019] (2) Deploy a link monitoring component in the firewall. The function of this component is to automatically copy the configuration of the main link of the open firewall to the backup link, and check the operating status of the network where the firewall is located in real time. The link monitoring component runs the self-inspection proce...

Abstract

This invention relates to a link backing up method for fire walls including: deploying a back up link on a fire wall having redundant hardware devices as the back up link then monitoring the working state of the entire link timely and starting up the back up link at once to switch to the back up link automatically in case abnormal things happen.

Description

Technical field: [0001] The invention relates to the technical field of firewalls, in particular to a link backup method of a firewall. Background technique: [0002] Firewall is currently the most widely used and effective security product in network security. It refers to the combination of a series of components set between different networks (such as trusted intranets and untrusted public networks) or network security domains. Protect internal network resources, prevent external illegal intrusion, and provide functions such as access control to internal and external network resources and audit supervision of internal and external users. With the development of firewall technology, firewall has become one of the main axes of the entire network security architecture. [0003] The basic principle of installing and deploying a firewall is: as long as there is a possibility of malicious intrusion, whether it is an internal network or a connection with an external public netw...
