Abstract

A method for preventing the denial of service attack based on backtracking technology with active network belongs to the information security technology field. By using dynamic allocation mechanism based on active network and combining backtracking technology, the invention builds the active backtracking system at each node in the attacked server, first makes the pre- judgement to the node, then judges the attacking algorithm, judges the target node in the packet header and other information, then makes defense backtracking, traces and eliminates the source of attack, finally eliminates the denial of service attack.

Description

technical field

[0001] The invention relates to a method for defending against denial of service attacks, in particular to a method for defending against denial of service attacks based on active network backtracking technology. It belongs to the field of information security technology. Background technique

[0002] Denial of service attack (DoS) sends a large number of service requests to the attacked host or other network devices in a very short period of time, causing the connection list of the target host to overflow, so that the target host cannot normally respond to other legitimate service requests. At present, there are many methods of defense denial of service attacks based on backtracking in the world, including entry debugging, controlled attacks, and IP marking adopted by the border, etc. (Stefan Savage, David Wetherall, Anna Karlin and Tom Anderson: Practical Network Support for IP Traceback. SIGCOMM2000Sweden: ACM, 2000.295~300), (Network Model Supporting IP ...
