随着计算机网络与信息技术的飞速发展,网络的应用已经延伸到社会和生活的各个领域,网络的安全威胁随之也在不断增加,信息网络的安全性越来越引起人们的重视。通常,利用加密技术来保证网络信息交换的安全性已经得到了人们的认可;在网络的出口处安装防火墙过滤不安全的服务,使内部阿与外部网络有效地隔离,极大地提高内部网络的安全性,降低网络风险。文章研究了基于网络嗅探器的安全防护、基于证书的安全防护两种计算机网络信息管理的安全策略。
With the rapid development of computer network and information technology, the application of network has extended to all fields of society and life. The threat of network security is also increasing. The security of information network has drawn more and more attention. In general, the use of encryption technology to ensure the security of network information exchange has been recognized; the firewall at the exit of the network to filter unsafe services, internal and external network effectively isolated, greatly improving the security of the internal network Reduce network risks. This paper studies the security strategy of network information management based on network sniffer security and certificate based security protection.
