基于局域网的安全技术分析

局域网的应用为资源共享、信息交换和分布处理提供了良好的环境 ,但同时也面临严重的安全技术问题。针对局域网中存在数据的可访问性、信息的聚生性和设防的困难性等问题。笔者从保护信息的机密性、完整性和可使用性的角度出发 ,提出应根据局域网的风险评价采用相应的安全技术 ,并论述了相关的安全技术对策。同时还指出仅仅靠单纯的技术措施是远远不够的 ,还应加强在安全监督管理工作和建立完善的应急预案 ,来确保局域网的安全

Security Technology Analysis on LAN

The application of LAN offers a fine environment for sharing resource, exchanging information and distributed processing, however, it also faces severe security problems, such as accessibility of the data, accumulation of information, and difficult to set defense, etc. According to the security evaluation of LAN, some corresponding security technology must be adopted to protect the confidentiality, integration and workability of the information. However, it's still not enough depending only on security technology, supervisory control system and perfect emergency pre protocol must be enhanced to ensure the security of the LAN.
