The function of firewall technology is mainly to discover and deal with the security risks and data transmission problems that may exist during the operation of computer network in time, among which the processing measures include isolation and protection, and at the same time, it can record and detect various operations in computer network security to ensure the security of computer network operation, ensure the integrity of user data and information, and provide users with better and safer computer network experience.

Firewall technology alarm function is very powerful, in the external user to enter the computer, the firewall will quickly send out the corresponding alarm, and remind the user's behavior, and carry out self-judgment to decide whether to allow external users to enter the internal, as long as it is in the network environment users, this firewall can effectively query, and at the same time find information to display to users, and then users need to implement the firewall according to their own needs corresponding settings, Block impermissible user behavior.

The log function in the internal part of the computer system In fact, it is also a summary and arrangement of the firewall's real-time security situation and daily traffic situation of the computer's internal system.
