The invention discloses an operating system feature hiding method and system based on a communication protocol, and belongs to the technical field of network security. Based on the characteristics of a communication protocol, corresponding fields of data packets interacted between an external network and an internal network are modified or forged, and then the data packets are sent to the external network, so the characteristics of an operating system of a protected host of the internal network are hidden. By adopting the method, the accuracy of detecting the operating system by an attacker can be effectively reduced, and leakage of network feature information is avoided. Moreover, the method is small in calculation amount and high in operation speed, has the advantages of being easy to implement, high in processing speed, flexible in application and the like, and can realize conversion of an information network security protection means from passive defense to active defense. 本发明公开了一种基于通信协议的操作系统特征隐藏方法及系统，属于网
