Safety In The Construction Of Network Firewall Technology Research And Application

For the computer network development, network security is looming on the horizon as a potentially massive problem. Security is a broad topic and covers a multitude of sins. In its simplest form, it is concerned with making sure that nosy people cannot read, or worse yet, modify messages intended for other recipients. It is concerned with people trying to access remote services that they are not authorized to use.The firewall technology uses for as at present to realize the network security measure one main method, it mainly is uses for to reject without authorization user's visit, prevents without authorization the user access sensitive data, simultaneously permits the validated user not the visit network resources which hinders. The firewall technology core thought is in the unsafe network environment a structure relative security sub- net environment In order to create the relative security the network environment, we need to understand the firewall the basic component, the type and its the firewall development tendency.Through the network firewall deployment, can effectively prevent the leakage of internal information, external network to prevent malicious intrusion staff. Through the use of a firewall on the internal network of the division can achieve focus on the internal network segment isolation, thus limiting the local network security key or sensitive issues on the impact of the overall network, greatly enhance the overall network security.
