随着网络的蓬勃发展,人们已经意识到网络安全是最迫切需要解决的问题之一。由于传统的计算机安全理论不能适应动态变化的、多维互联的网络环境,于是可适应网络安全理论体系逐渐形成。可适应网络安全理论(或称动态信息安全理论)的主要模型是P~2DR模型(如附图)。P~2DR模型给网络安全管 With the rapid development of the Internet, people have realized that network security is one of the most urgent problems to be solved. Due to the traditional computer security theory can not adapt to the dynamic and multi-dimensional interconnected network environment, it can adapt to the network security theory system gradually formed. The main model that can adapt to network security theory (or dynamic information security theory) is the P ~ 2DR model (as the figure). P ~ 2DR model to network security management
