【摘要】：諸如個人電腦(Personal Computer, P)、平板、智能電視和機頂盒等智能終端設備近幾年變得日益普及,這些智能設備在為人們提供便捷高效生活的同時,也逐漸暴露出越來越多的安全隱患。與此同時,僵尸網(wǎng)絡在近幾年也開始向各種終端平臺滲透,像手機、路由器、機頂盒等平臺上均已出現(xiàn)了僵尸網(wǎng)絡的蹤跡�？梢灶A見,未來隨著智能終端市場的進一步擴大,僵尸網(wǎng)絡在智能終端領域?qū)䴓?gòu)成越來越大的威脅。所以,在融合當前多種智能終端設備的環(huán)境中,研究僵尸網(wǎng)絡發(fā)展的新形態(tài)新趨勢,具有十分重要的現(xiàn)實意義。我們通過對融合環(huán)境下智能終端僵尸網(wǎng)絡的命令控制信道、滲透傳播、統(tǒng)一管控等方面的研究,來評估構(gòu)建這種僵尸網(wǎng)絡的可行性和其危害性,同時也為未來僵尸網(wǎng)絡的防御提供新的思路。 本文首先介紹了當前智能終端設備和僵尸網(wǎng)絡的發(fā)展現(xiàn)狀和趨勢。然后,對當前主流智能終端設備的特點和脆弱性進行了分析研究,探討其有可能被僵尸網(wǎng)絡利用到的各個薄弱環(huán)節(jié)。在融合環(huán)境這一全新背景下,本文創(chuàng)新性地提出一種適用于智能終端僵尸網(wǎng)絡的命令控制信道構(gòu)建方法,并且將僵尸網(wǎng)絡自動傳播機理的研究范疇從單一平臺擴展到了多設備平臺上,實現(xiàn)了一個跨終端的交叉?zhèn)鞑ジ腥痉桨浮?以對智能終端僵尸網(wǎng)絡的關鍵技術研究為基礎,我們構(gòu)建了一個僵尸網(wǎng)絡原型系統(tǒng),以此評估和確認了這種新類型僵尸網(wǎng)絡的可行性和危害性,并且從防御角度,提出了具有針對性的防御策略。 最后,本文總結(jié)了論文的主要工作,并對未來工作進行了展望。
[Abstract]:In recent years, intelligent terminal devices such as personal computer (Personal Computer, P), tablet, smart TV and set-top box have become increasingly popular. These intelligent devices provide people with convenient and efficient life, but also gradually exposed more and more security risks. At the same time, botnet also began to penetrate into various terminal platforms in recent years, such as mobile phones, routers, set-top boxes and other platforms have appeared on the botnet traces. It can be predicted that with the further expansion of intelligent terminal market, botnet will pose more and more threat in intelligent terminal field. Therefore, it is of great practical significance to study the new form and trend of botnet development in the environment of merging various intelligent terminal devices. We evaluate the feasibility and harmfulness of constructing this kind of botnet by studying the command control channel, penetration propagation, unified control and so on of intelligent terminal botnet in fusion environment. At the same time, it also provides new ideas for the future botnet defense. This paper first introduces the current situation and trend of intelligent terminal equipment and botnet. Then, the characteristics and vulnerabilities of the current mainstream intelligent terminal devices are analyzed and studied, and the weak links that may be used by botnets are discussed. Under the new background of fusion environment, this paper proposes an innovative command control channel construction method for intelligent terminal botnet. And the research scope of botnet automatic transmission mechanism is extended from single platform to multi-device platform to realize a cross-transmission infection scheme of cross-terminal. Based on the research on the key technology of intelligent terminal botnet, we construct a botnet prototype system to evaluate and confirm the feasibility and harmfulness of this new type of botnet, and from the point of view of defense. A specific defense strategy is proposed. Finally, this paper summarizes the main work of the paper, and prospects for future work.
