土壤墒情网络监测系统的洪涝、干旱及火灾等报警功能关系着生命财产的安全,作为系统核心的监测主机的安全至关重要。通过全面分析监测主机可能面临的病毒、黑客、硬件故障、操作人员因素、自然灾害等安全威胁,以预防和恢复为指导思想,确定具体的安全策略,进而建立起监测主机的全方位层式安全模型。该模型具有预防、恢复、审计追踪三层,综合考虑了各种安全威胁,具有全方位的保护作用。采用《可信计算机系统评测标准》对该安全模型进行了评价,结果表明其安全性能较高。
Soil Moisture Network monitoring system flood, drought and fire alarm functions related to the safety of life and property, as the core of the system to monitor the safety of the host is essential. Through a comprehensive analysis and monitoring of the host may face security threats such as viruses, hackers, hardware failures, operator factors and natural disasters, take the prevention and recovery as the guiding ideology to determine the specific security strategy, and then establish a comprehensive host-level security monitoring host model. The model has three layers of prevention, recovery and audit trail, taking various security threats into consideration and having all-around protection. The security model was evaluated by “Trusted Computer System Evaluation Criteria” and the results showed that its security performance was high.
