Active defense method for network trick and counter attack

Abstract

The invention discloses an active defense method for a network trick and a counter attack. The method comprises the following steps that two communication sides set a plurality of host computers for data sending and receiving, and one host computer is dynamically and randomly selected as a communication host computer through an address and port hopping server; a sender selects one or more transmission links to send a trick message to detect the safety and the channel quality of the transmission links, wherein if the links are safe, true data with the counter attack are constructed and sent, and meanwhile the sender continues to send the trick message to detect the links; an intermediate node takes in charge of detecting and feeding the safety situation of the transmission links back to a network administrator; the network administrator updates a transmission path according to the safety situation of the node and takes the defensive measure. The active defense method can effectively prevent and detect common safety attack in the network communication and carry out certain counter attack on an attacker.

Description

technical field [0001] The invention relates to the field of communication network security defense, in particular to an active defense method for network deception and anti-attack. Background technique [0002] In recent years, with the development of communication network technology, various types of network applications have emerged as the times require, and governments and individuals are increasingly dependent on the network. At the same time, there is a steady stream of attacks against the network. Despite the various methods and tools used to secure network communications, the number of successful attacks continues to rise. From the initial port scanning attack, buffer overflow attack, to the current Distributed Denial of Service attack (Distributed Denial of Service), network monitoring and man-in-the-middle attack, new attack means and methods emerge in an endless stream, ever-changing. [0003] Traditional network security protection systems, such as firewalls an...
