Therefore, This makes the enterprise must reexamine the security problems of current information system faces. and find out effective safe guard technology for enterprise from it. The article has make the Analysis and Research of the Enterprise facing work security problems from the aspects of Physical security, system security, application security, management security, hacker attacks, virus damage and so on, And puts forward a series of countermeasures to solve, including. Through the method of dividing VLAN, use encryption technology、 authentication technology to guarantee system security。 rely on the preventing hacker attacks technology and the work antivirus technology, solve the work security problem when connect the external work。 Deals with the loopholes in management the establishment of a safety management system. At last, with an example to illustrate how to build enterprise information security system Keywords: Information security Management system Network technology 成都信息工程學(xué)院銀杏酒店管理學(xué)院本科畢業(yè)論文 III 目 錄 引言 .................................................................................................................................................. 1 1 信息安全的相關(guān)定義 ................................................................................................................... 1 信息安全 .............................................................................................................................. 1 信息安全的基本屬性 .......................................................................................................... 2 2 網(wǎng)絡(luò)環(huán)境下企業(yè)信息安全分析 ................................................................................................... 3 物理安全 .............................................................................................................................. 3 系統(tǒng)安全 .............................................................................................................................. 3 黑客攻擊 .............................................................................................................................. 4 網(wǎng)絡(luò)病毒風(fēng)險(xiǎn) ...................................................................................................................... 4 應(yīng)用管理安全 ...................................................................................................................... 5 3 網(wǎng)絡(luò)環(huán)境下企業(yè)信息安全對策 ................................................................................................... 5 物理安全對策 ...................................................................................................................... 5 機(jī)房環(huán)境安全 ......................................................................................................... 5 通信線路安全 ......................................................................................................... 5 電源等設(shè)備安全 ..................................................................................................... 6 系統(tǒng)安全對策 ...................................................................................................................... 6 VLAN（虛 擬局域網(wǎng)）技術(shù) ................................................................................... 6 認(rèn)證技術(shù) ............................................................................................................. 7 信息加密技術(shù) ..................................................................................................... 8 黑客攻擊對策 ...................................................................................................................... 8 防火墻技術(shù) ............................................................................................................. 8 入侵檢測技術(shù) ....................................................................................................... 10 網(wǎng)絡(luò)病毒對策 .................................................................................................................... 11 病毒防治體系特性 ............................................................................................... 11 病毒防治軟件安裝 ............................................................................................... 11 病毒防護(hù)體系的自動(dòng)控制 ................................................................................... 12 應(yīng)用管理安全對策 ............................................................................................................ 12 人事管理 ............................................................................................................... 13 場地設(shè)施管理 ....................................................................................................... 13 設(shè)備管理 ............................................................................................................... 13 軟件管理 ............................................................................................................... 13 口令管理 ............................................................................................................... 14 網(wǎng)絡(luò)管理 ..............................................
