海洋信息技术与应用

本文在总结态势感知技术现有研究成果的基础上，借鉴其他行业单位的应用经验，提出了一种符合海洋网络运维实际情况、基于大数据架构的网络安全态势感知模型，并将该模型应用于海洋网络的安全防御中。应用实践表明，海洋态势感知系统能全方位展示资产脆弱性、访问关系等海洋网络安全态势，实现安全防护工作由被动防御向主动监管的转变。

Based on a synthesis of existing research achievements in situation awareness technology and insights from application experiences in other industries, this paper proposes a cybersecurity situation awareness model tailored to the characteristics of maritime networks and built upon a big data architecture. This model is subsequently applied to the security defense of maritime networks. Practical applications demonstrate that the maritime situation awareness system provides a comprehensive overview of the network security posture, including asset vulnerabilities, security status, and access relationships. This facilitates a shift in security protection from a passive defense paradigm to proactive monitoring and governance.
