实现系统安全的技术方案分析

首先讨论了安全模型P2DR的理论概念及其体系结构,依据安全模型的四要素关系及时间值概念,给出了系统安全的定义公式。对安全防御技术和入侵检测技术分别进行了优缺点分析,得出两种技术需有效结合才能符合P2DR安全模型的安全要求。安全联动技术是当前系统安全研究的热点,属于一种新型的安全整合技术,提出了该技术在研究过程中需要解决的相关问题,以满足技术的开放性要求。

Analysis of Technical Solutions to Achieve System Security

The theory and architecture of security model P2DR is discussed firstly,and then the formula definition of system security is given based on the relationship of P2DR model＇s four elements and time value concept.The analysis on advantages and disadvantages of secure defense technology and intrusion detection technology comes to the conclusion that the effective integration of these two technologies is in line with the security requirements of P2DR security model.Security linkage technology as a new type of security integration technology is the current research hotspot.Related issues needed to handle during the security linkage technology research are proposed in order to meet the open system requirements.
