Telnet proxy method and architecture separated from protocol stack, and medium

Abstract

The invention provides a telnet proxy method and architecture separated from a protocol stack and a medium, and the method comprises the following steps: reading a connection list after an input proxy receives a first telnet message request packet, and judging whether a client sending the first telnet message request packet is registered in the connection list or not; if the client is registered in the connection list, forwarding the first telnet message request packet to a main heterogeneous module of a heterogeneous platform, modifying a TCP header in the first telnet message request packet, repackaging the TCP header into a second telnet message request packet, and forwarding the second telnet message request packet to a slave heterogeneous module of the heterogeneous platform; and after a telnet message response packet returned by a certain heterogeneous module is received, if the heterogeneous module sending the telnet message response packet is a main heterogeneous module, forwarding the telnet message response packet to the target client.

Description

technical field [0001] The present invention relates to the technical field of mimicry defense, in particular, relates to a telnet proxy method, framework and medium that are separated from the protocol stack. Background technique [0002] With the rapid development of the Internet, network security has gradually become a potentially huge problem. Introducing the active defense method into the cyberspace can solve cyberspace security problems, especially in the face of the current biggest security threats - unknown vulnerabilities, backdoors, virus Trojans and other uncertain threats. It has a significant effect and overcomes the existence of traditional security methods. In view of many problems, the theory of Cyberspace Mimic Defense (CMD) came into being. [0003] The purpose of CMD technology is to integrate multiple active defense elements: to change the similarity and unity of the target system with heterogeneity, diversity or diversity; to change the static and deter...

Problems solved by technology

[0004] In a heterogeneous system, user data needs to be forwarded to the internal heterogeneous platform, and the input agent must be able to maintain connections with different heterogeneous modules in the heterogeneous platform. The most typical network connection is a telnet connection; the usual telnet input agent Need to run on the protocol stack, maintain the connection through reverse proxy, need to establish multiple telnet connections at the same time, due to the open source nature of the protocol stack, there will inevitably be loopholes
