Abstract: By analyzing the networking character values actively and passively，attacker can get a lot of information about target host，such as the type of operating system.And follow these information，they can guess the system vulnerability.So these transparent values are very useful for the successful attack and intrusion process.In order to resolve above problems，this paper presents the network camouflaging model，which is based on the principle of camouflaging.Active camouflaging for network session is used to defeat the passive sniffle and detection，and passive camouflaging is used to defeat the active detection.As a result，the real network character values are hided and the camouflaged values are presented for the attacker.The experiment shows that the real networking character values are hided successfully.

Key words: network camouflaging, networking character value, network detection
