【正文】 交流的數(shù)據(jù)出入口,即是 “門(mén)窗 ”。 每一個(gè)網(wǎng)絡(luò)主機(jī)都相當(dāng)于一個(gè) “房間 ”,黑客能否進(jìn)入 “房間 ”,取決于是否發(fā)現(xiàn)了打開(kāi)的 “門(mén)窗 ”。 Network security bees the focus which people pay attention to. PortScanning Technology is one of the most important technologies of the safe scanning on inter. The first step that work system intruders enter the target system is the port scanning of the system. This essay explains the principle and application of the port scanning technology, and then designs a simple portscan system which bases on the Windows platform. The paper introduces the SYN probe technology of the semiopen scan technologies, analyzes its implementing principle, approach and characters. In the real design it use the SYN probe technology which has a better scanning security and feasibility to achieve the Port Scanning, then realize userdefined port list function, recording of the scanning result, and some other functional modules. At last, bined with the nowadays actual situation, the paper brings a few personal minds for the future direction of the development of the PortScanning. Key words: Network security; Port scanning; SYN probe 目 錄 論文總頁(yè)數(shù): 22 頁(yè) 1 引言

測(cè)在網(wǎng)絡(luò)安全中起著主動(dòng)防御的作用,占有非常重要的地位。最后結(jié)合當(dāng)前的實(shí)際情況對(duì)端口掃描的未來(lái)發(fā)展方向提出了一點(diǎn)個(gè)人的看法。在論文中介紹了半打開(kāi)掃描中的 SYN探測(cè)技術(shù),分析了這種掃描技術(shù)實(shí)現(xiàn)的原理和特點(diǎn)。對(duì)目 標(biāo)系統(tǒng)進(jìn)行端 口 掃描 ,是網(wǎng)絡(luò)系統(tǒng)入侵者進(jìn)入目 標(biāo)系統(tǒng)的第一步 。 畢業(yè)設(shè)計(jì) ( 論文 ) 基于 半打開(kāi) 的端口掃描技術(shù) 的 實(shí)現(xiàn) 論文作者姓名: 申請(qǐng)學(xué)位專(zhuān)業(yè): 申請(qǐng)學(xué)位類(lèi)別: 指導(dǎo)教師姓名(職稱(chēng)): 論文提交日期: 基于半打開(kāi) 的端口掃描技術(shù) 的 實(shí)現(xiàn) 摘 要 隨著互聯(lián)網(wǎng)的飛速發(fā)展 ,網(wǎng)絡(luò)入侵行為日益嚴(yán)重,網(wǎng)絡(luò)安全 日益成為人們關(guān)注的焦點(diǎn)。 端口掃描技術(shù) 是網(wǎng)絡(luò)安全掃描技術(shù)的重要技術(shù)之一。 本 文對(duì)端口掃描技術(shù)的原理和應(yīng)用進(jìn)行了闡述 ,并設(shè)計(jì)了一個(gè)簡(jiǎn)單的基于 windows平臺(tái)上的端口掃描系統(tǒng)。實(shí)際設(shè)計(jì)中采用了掃描安全性和可行性較好的 SYN探測(cè)技術(shù) 來(lái)實(shí)現(xiàn)端口掃描 ,并實(shí)現(xiàn)了 端口列表自定義,掃描結(jié)果存儲(chǔ)等幾大模塊化功能。 關(guān)鍵詞 : 網(wǎng)絡(luò)安全;端口掃描; SYN 探測(cè) The Implementation of a Portscanning Program Based on Semiopened Port Technology Abstract With the quick development of the inter, work intrusion behavior bees more and more serious。網(wǎng)絡(luò)安全探測(cè)的所有功能都是建立在端口掃描的基礎(chǔ)上,所以對(duì)端口掃描技術(shù)的研究有著非常重要的現(xiàn)實(shí)意義。也就是說(shuō),能否入侵網(wǎng)絡(luò)主機(jī),或者網(wǎng)絡(luò)主機(jī)是否安全,關(guān)鍵在于能否查出網(wǎng)絡(luò)主機(jī)的系統(tǒng)信息。端口分為硬件端口和軟件端口,所謂硬件端口又稱(chēng)為接口,包括: USB 端口、串行端口、并行端口等。一個(gè)端口就是一個(gè)潛在的通信通道,也就是一個(gè)入侵通道。
