目前,我國電信網路正處于高速發展中,網路的規模越來越大,設備種類越來越多,組網方式越來越多樣化,應用越來越復雜,但是網路管理系統仍然普遍採用管理員/代理的集中式管理方法,在集中式網路管理模式中,網管系統不能隨著網路規模和復雜度的變化而變化,致使網管系統越來越龐大;網路管理邏輯全部集中在一個管理工作站中計算,需要佔用大量的帶寬來傳輸設備數據,有效性差,同時管理工作站是系統中最脆弱的部分,一旦管理方超負荷或死機,代理方因為必須等待管理方的指令而無法恢復系統,導致系統崩潰。And illustrates that the types of the crime of the network are : network hacker ; making and propagating computer virus ; network attacking and destroying ; network pornography ; etc. then analyses the reason why the crime of the network produces from three respects of internal, external cause and psychological factors, the internal cause refers to the fragility of network itself mainly ; then analyses some external causes such as the consciousness of network security is deficient, the safe mechanism of management lags behind ; and analyzes the psychological factors of subject emphatically : nihility of the crime sense, having idea of leaving things to chance, thin legal consciousnesses
繼而從內、外因及主體因素三方面分析了網路犯罪產生的原因,內因主要是指網路本身的脆弱性。在外因中分析了諸如經濟利益的驅使;網路安全意識欠缺,安全管理機制落後;規制網路犯罪的法制不健全,對網路犯罪打擊力度不夠;缺乏共同的國際標準等客觀因素,而且著重分析了主體的心理因素和意識因素即犯罪感的虛無化、存在僥幸心理、法律意識淡薄,從而找出了網路犯罪的「病因」 ,以便「對癥下藥」 。This research provides an analysis of the integrated mechanism of the emergence and expansion of the different types of desert lands, and compares this mechanism with the theory of ecotone. the paper discusses the relationship between ecological fragility and desertification. it concludes that with the environmental vulnerabilities, ecotone lands are easily desertified under the adverse human exploitation. because exploitation of the ecotone lands makes the environment more vulnerable, human should act to use the lands in a way compatible with the environment. the control of desertification is also discussed
