"Automatic Handling Of Protocol Dependencies And Reaction To 0-Day Attacks With ScriptGen Based Honeypots"
Thursday, June 7. 2007
At the 9th International Symposium On Recent Advances In Intrusion Detection (RAID'06), Corrado Leita, Marc Dacier, and Frederic Massicotte presented an update of their ScriptGen tool. In the paper "Automatic Handling Of Protocol Dependencies And Reaction To 0-Day Attacks With ScriptGen Based Honeypots", they show how ScriptGen can be extended to effectively handle unknown protocols.
Abstract:
Spitzner proposed to classify honeypots into low, medium and high interaction ones. Several instances of low interaction exist, such as honeyd, as well as high interaction, such as GenII. Medium interaction systems have recently received increased attention. ScriptGen and RolePlayer, for instance, are as talkative as a high interaction system while limiting the associated risks. In this paper, we do build upon the work we have proposed on ScriptGen to automatically create honeyd scripts able to interact with attack tools without relying on any a-priori knowledge of the protocols involved. The main contributions of this paper are threefold. First, we propose a solution to detect and handle so-called intra-protocol dependencies. Second, we do the same for inter-protocols dependencies. Last but not least, we show how, by modifying our initial refinement analysis, we can, on the fly, generate new scripts as new attacks, i.e. 0-day, show up. As few as 50 samples of attacks, i.e. less than one per platform we have currently deployed in the world, is enough to produce a script that can then automatically enrich all these platforms.
