针对纵向加密装置的网络安全威胁分析

Network security threat analysis for vertical encryption device

纵向加密装置是电力二次系统网络安全的重要保证,针对纵向加密装置的攻击直接影响电力调度数据网的稳定运行。文章阐述了纵向加密装置的主要性能指标,着重围绕针对其可用性的威胁展开分析,并将此类威胁定义为拒绝服务威胁,进一步给出拒绝服务攻击的两种类型及其特征。基于纵向加密装置拒绝服务攻击的特点,给出了有针对性的防御措施。

Vertical encryption device is an important guarantee of power secondary system network security. The attack on encryption gateway directly affect the stable operation of electric power dispatching data network. The main performance indexes of encryption gateway are described in this paper. Attack on availability of encryption gateway is defined as denial of service threat,and further two types of denial of service attacks and their characteristics are also given,and some defense measures are suggested.
