E - business software interacts with a wide variety of existing back office systems , including database , accounting , and erp systems 企業級電子商務解決方案應該能夠與erp或現有會計系統密切整合,保持商務活動與資金流的同步。
Being a widely utilized public ip platform , it is susceptible to security attacks of all nature , as outlined in the following areas : the open nature of the ip internet systems - increase of foreign attacks , for example dos / ddos attacks ; the current weakness of the existing operating system ' s internet protocol ; mainframe , and lack of an evaluation standard for back office systems , the inevitable problem of illegal internal access , the lack of guidelines for record keeping and post attack documentation processes , hi addition , still in existence , are managerial problems including the lack of securit y knowledge amongst the workforce and the inexistence of a complete set of security guidelines . to guarantee china telecom ' s 163 / 169 system ' s reliable functions , to protect the user ' s interests , at the same time , insuring quality service , it is necessary to adapt p2dr model as a solution to the current security issues . supported by the modern secure theory and made the secure implementation abundant project practices , this paper gives the general secure design for the chongqing public ip network using p2dr secure model 中國電信建設的公眾ip網對我國internet的發展起著決定性作用,重慶電信163 / 169互聯網是國家骨干網在本地的延伸,擁有7個核心節點(采用cisco12012 、 2 * 2 . 5gdpt環) ,三十八個匯接節點,能提供寬帶,窄帶多種接入方式的公眾ip網,現擁有近20萬用戶,占全市互聯網用戶四分之三以上,作為這樣一個擁有眾多用戶,開放的ip平臺,會受到各種各樣的安全威脅,主要表現在ip網絡的開放性,來自外部的攻擊增多,如dos / ddos攻擊;所使用的操作系統運行的網絡協議自身的脆弱性;主機、網絡設備的配置是否缺乏評估手段;不可避免的內部非法訪問;缺乏必要的攻擊審計作為犯罪取證,出此之外,還有管理上的一些問題,如人員安全意識不強,安全制度不夠健全等多方面原因。
