4 . presentation of buffer overflow attack model based on category theory . buffer overflow attack model based on category theory is brought forward in the paper by exploring the process of buffer overflow attack and systematically summarize its attack process 4 .給出了以范疇論描述的緩沖區(qū)溢出攻擊模型通過(guò)對(duì)緩沖區(qū)攻擊過(guò)程的研究,提出了以范疇論描述的緩沖區(qū)溢出攻擊模型,對(duì)緩沖區(qū)溢出攻擊過(guò)程進(jìn)行了系統(tǒng)地總結(jié)。
In this paper , technology of ddos and design of d - gun are introduced . totally it is divided into six parts , the first of part is introduction . the second part is interrelated technology about d - gun , including ddos principium , ports - scan , buffer overflow attack , backdoor and raw socket 第二部分介紹相關(guān)技術(shù)基礎(chǔ),主要討論了ddos原理和實(shí)現(xiàn)ddos自動(dòng)傳播執(zhí)行所需具備的相關(guān)技術(shù),包括端口掃描技術(shù)、遠(yuǎn)程入侵技術(shù)、后門(mén)技術(shù),以及tcp / ip協(xié)議應(yīng)用中的原始套接字。
