One of the goals of smart environments is to improve the quality of human life in terms of comfort and efficiency. The Internet of Things (IoT) paradigm has recently evolved into a technology for building smart environments. Security and privacy are considered key issues in any real-world smart environment based on the IoT model. The security vulnerabilities in IoT-based systems create security threats that affect smart environment applications. Thus, there is a crucial need for intrusion detection systems (IDSs) designed for IoT environments to mitigate IoT-related security attacks that exploit some of these security vulnerabilities. Due to the limited computing and storage capabilities of IoT devices and the specific protocols used, conventional IDSs may not be an option for IoT environments. This article presents a comprehensive survey of the latest IDSs designed for the IoT model, with a focus on the corresponding methods, features, and mechanisms. This article also provides deep insight into the IoT architecture, emerging security vulnerabilities, and their relation to the layers of the IoT architecture. This work demonstrates that despite previous studies regarding the design and implementation of IDSs for the IoT paradigm, developing efficient, reliable and robust IDSs for IoT-based smart environments is still a crucial task. Key considerations for the development of such IDSs are introduced as a future outlook at the end of this survey.

基于物联网的智能环境的入侵检测系统：一项调查

智能环境的目标之一是在舒适性和效率方面改善人类生活的质量。物联网（IoT）范式最近已演变为一种用于构建智能环境的技术。在基于IoT模型的任何现实世界的智能环境中，安全性和隐私被视为关键问题。基于物联网的系统中的安全漏洞会产生影响智能环境应用程序的安全威胁。因此，迫切需要为物联网环境设计的入侵检测系统（IDS），以缓解利用其中一些安全漏洞的物联网相关安全攻击。由于物联网设备的计算和存储功能有限以及所使用的特定协议，传统的IDS可能不是物联网环境的选择。本文对针对IoT模型设计的最新IDS进行了全面调查，重点介绍了相应的方法，功能和机制。本文还提供了对IoT架构，新出现的安全漏洞及其与IoT架构各层之间关系的深入了解。这项工作表明，尽管先前就物联网范例的IDS的设计和实现进行了研究，但为基于IoT的智能环境开发高效，可靠和强大的IDS仍然是一项至关重要的任务。在本调查结束时，介绍了开发此类IDS的主要注意事项，作为对未来的展望。新兴的安全漏洞，以及它们与物联网架构各层的关系。这项工作表明，尽管先前就物联网范例的IDS的设计和实现进行了研究，但为基于IoT的智能环境开发高效，可靠和强大的IDS仍然是一项至关重要的任务。在本调查结束时，介绍了开发此类IDS的主要注意事项，作为对未来的展望。新兴的安全漏洞，以及它们与物联网架构各层的关系。这项工作表明，尽管先前就物联网范例的IDS的设计和实现进行了研究，但为基于IoT的智能环境开发高效，可靠和强大的IDS仍然是一项至关重要的任务。在本调查结束时，介绍了开发此类IDS的主要注意事项，作为对未来的展望。
