什么是等保
信息安全等级保护（后文中简称为“等保”）是对信息和信息载体按照重要性分成不同的级别进行保护的一种工作，“等保”，即信息安全等级保护，网络安全等级保护是指对网络（含信息系统、数据等）实施分等级保护、分等级监督，对网络中发生的安全事件分等级响应、处置。
涉及什么范围
各个部门 、单位、机构、企业，有信息系统定级需求的行业与单位
等保2.0标准
在1.0标准的基础上进行了优化，同时针对云计算、移动互联、物联网、工业控制系统及大数据等新技术和新应用领域提出新要求，形成了安全通用要求+新应用安全扩展要求构成的标准要求内容
等保一共分几个等级
第一级（自主保护级）；第二级（指导保护级）；第三级（监督保护级）；第四级（强制保护级）；第五级（专控保护级）
等保保护流程
分为5个环节，定级、备案、建设整改、等级测评、监督检查。
