为配合《中华人民共和国网络安全法》的实施，指导网络运营者贯彻落实网络安全等级保护制度，国家市场监督管理总局、中国国家标准化管理委员会发布了国家标准：《信息安全技术 网络安全等级保护基本要求》（GB/T 22239-2019）（以下简称《基本要求》）。
《基本要求》是网络安全等级保护制度的重要组成部分，是开展网络安全等级保护建设、等级测评等工作的核心标准。正确理解和使用《基本要求》，是有效开展新网络安全等级保护工作的基础。
为便于读者循序渐进地学习、理解《基本要求》，本书首先对该标准所涉及的等级保护基本概念、应用场景等分别进行了介绍，使读者对《基本要求》的结构、适用范围等有一个总体的了解，在此基础上，对《基本要求》各条款进行了详细的解读、说明，便于读者更好地理解和掌握并应用于实际工作中。
