Answer 1

Abstract: A firewall is a technological measure developed in recent years to protect the security of a computer network, it's also the most widely used technology of a network security protection now. A firewall is one or a set of system to access controling policies, it can be software, hardware or a combination of them, whose aim is to provide security protection for the network. A firewalls is usually located between internal and external networks, and it can monitor, control and change communications in the internal and external networks, and controling external computers can visit internal protected environment and determine the access time, authorities, the types of service and quality.It checks the spread of the internal information to avoid the outflow of confidential information and resist external invasion and prevent internal information leaking. This paper presents the importance of firewall configuration in the network security, and explains that the set of firewall rules is an important measure for firewall product security.
Key words: firewall,configuration,network,security

Answer 2

In recent years the firewall is one kind of protection computer network security technical measure which develops, is also uses the most widespread one kind of network security to protect the technology at present. The firewall is or a group implements the access control strategy the system, it may be the software, the hardware or software and hardware's union, its goal is provides to the network safekeeping of security. The firewall usually is located at between the internal network and the exterior network, may monitor, the control and the change the network service which flows between the interior and the exterior network; Controls the exterior computer to be possible to visit the interior the environment which protects, and determined the visit the time, the jurisdiction, the service type and the quality and so on, the inspection interior spreads the information, avoids the privacy information flowing out, achieves resists exterior invades and prevents the goal which the insider information divulges a secret. This article proposed firewall's disposition in network security's importance, has explained the firewall ruleset is the firewall product security important measure.

Answer 3

The firewall is developed in recent years to protect a computer network security technology, is currently the most widely used of a network security technology. The firewall is one or a group of access control strategy for the implementation of the system, which can be software, hardware or a combination of hardware and software, its purpose is to provide security protection for the network. Firewalls often in the internal network and external networks, can monitor, control and changes in internal and external networks of the mobile communication network; control external access to internal computer protected environment, and to determine the time to visit, competence, the types of service And quality, check the spread of internal information, avoid the outflow of confidential information, to resist external invasion and prevent the leakage of internal information purposes. This paper presents a firewall configuration in the importance of network security, explain the firewall rule set is a firewall product safety is an important measure.
