分析地震行业信息系统的现状和需求，以及在当前环境下如何结合等级保护做好信息安全工作。以山东省地震局为例，通过对安全技术体系、安全管理体系的研究和利用IPsecVPN、UTM等技术构建自防御体系及该体系的整体部署、实施最终建立起一套信息安全体系。通过作者在该方面所做的工作，发现将该安全体系的研究成果应用到整个地震行业信息业务中具有很重要的实际意义。

The analytical study earthquake profession information system's present situation and did the demand, how as well as unify the rank protection under the current environment to do the information security work. Take the Shandong Province earthquake authority as the example, through to the safety work system, the safety control system's research and from defensive system's construction and this system's whole deployed that the implementation establishes a set of information security system finally, through the author the work which does in this aspect, discovered that applies in the entire earthquake profession information service this security system's research results to have the very vital practical significance.
