Onshore distribution and security protection method of seabed observation network data

Abstract

The invention discloses an ashore distribution and security protection method of sea floor observation network data. A virtual local area network is established to distributing the data of different types from the same data source; the data that can be publically issued are transmitted to an extranet server, while the sensitive data are transmitted to an intranet server. An external firewall is deployed between the extranet server and the backbone internet, a security protection system is loaded for the extranet server, and an internal firewall is deployed between the extranet server and the intranet, and therefore, a data security protection method involving the external firewall, the extranet server security protection system and the internal firewall is completed. The externally disclosed data parameters of the extranet server include temperature, salinity, corresponding water depth and the like; the protected sensitive data parameters of the intranet server include hierarchical sea current data and the like. The ashore distribution and security protection method of the sea floor observation network data based on the virtual local area network guarantees real-time external release of the public data, strengthens the protection on the intranet sensitive data and effectively prevents the attack of network malicious programs.

Description

technical field [0001] The invention relates to a method for transmitting ocean observation data, in particular to a method for distributing and protecting data on the shore of a seabed observation network based on a virtual local area network. Background technique [0002] With the development of communication, computer and Internet technology, ocean observation data are more and more applied to various fields through the network. However, due to some insecure factors of the network, there are risks in the release of ocean observation data on public platforms. [0003] The elements of ocean observation data are diverse, mainly including dynamic elements such as wind, wave and current, physical elements such as temperature, salt and depth, and chemical elements such as pH and dissolved oxygen. Among them, the release of data such as wind and waves plays a great role in effectively warning natural disasters and guiding various offshore operations. The release of data such as ...

AI Technical Summary

Problems solved by technology

The data security protection function of the traditional transmission and release methods of ocean observation data is poor. Once the data source or data server is attacked, the way all data is packaged and transmitted is also likely to cause all data to be violated, especially some sensitive data.
