一种计算机网络防御策略描述语言魏玉娣 夏春和 李肖坚 王海泉 何 巍


  摘 要:定义了一种计算机网络防御策略描述语言(computer network defense policy specification language,CNDPSL)。该语言面向CNDPM模型,能够统一描述保护、检测和响应策略,并通过策略引擎映射为相应的防御规则。CNDPSL是一种声明式语言,抽象了网络防御控制的行为,对网络防御需求具有较好的灵活性、可扩展性和适应性。在GTNetS仿真平台中的实验表明,该语言能够描述防御策略并有效地转换为防火墙的ACL、检测和响应规则等,从而为计算机网络攻防演练提供防御策略支持。

  Abstract: This paper defined a new computer network defense policy specification language (CNDPSL). This language provided a common method of specifying protection, detection and response policies based on CNDPM model, which could be mapped to corresponding defense rules by policy engine. CNDPSL was declarative abstracting defense control behavior of network which made this language flexible, extensible and adaptable to network defense requirements. Experiments in GTNetS platform indicated that it can describe defense policies and transforms to ACL (access control list) in firewall, IDS detection rules, response rules and so on. The above information shows that CNDSPL can provide defense policy support for computer network attack & defend simulation.
