基于网络特征混淆的欺骗防御技术研究

网络攻击之前通常有侦查阶段,攻击者通过流量分析和主动扫描等技术获取目标系统的关键信息,从而制定有针对性的网络攻击.基于网络特征混淆的欺骗防御是一种有效的侦查对抗策略,该策略干扰攻击者在侦查阶段获取的信息,从而使攻击者发动无效的攻击.对现有混淆欺骗防御方案的技术原理进行了分析,给出了网络混淆欺骗的形式化定义,并从3个层次...

Research on deception defense techniques based on network characteristics obfuscation

There is usually a reconnaissance stage before a network attack, the attacker obtains the key information of the target system through techniques such as traffic analysis and active scanning, to formulate a targeted network attack.Deception defense techniques based on network characteristics obfuscation is an effective strategy to confront network reconnaissance, which makes the attacker launch an ineffective attack by thwarting the attacker's reconnaissance stage.The technical principle of the existing obfuscation defense solutions was analyzed, the formal definition of network obfuscation was given, the existing research works were discussed from three aspects, and finally the development trend of the obfuscation deception defense technique were analyzed.
