Undoubtedly, modern human digital lives are every day more and more connected, and the revolution of “everything connected” is already becoming a reality. Indeed, humans live in the age of the Internet of Things (IoT), and one of the most usual IoT contexts is a smart home. Unfortunately, such significant enhancement also means that common home devices, such as fridges, cameras, or even bulbs, are exposed to malevolent entities whose primary goal is to threaten the confidentiality, integrity, and availability of the automatically-exchanged information. Aiming at fine-tuning the protection of the smart devices, this paper proposes a novel dynamic rule management solution adaptable to the current status of the IoT environment, so to protect it against cyberattacks. Experiments demonstrated that a notable reduction in the CPU and RAM consumption was achieved when applying this novel scheme. Additionally, the number of packets processed per second increased substantially, inducing a meaningful enhancement also from a security perspective.

毫无疑问，现代人类数字生活越来越紧密地联系在一起，“万物互联”的革命已经成为现实。确实，人类生活在物联网（IoT）时代，最常见的IoT环境之一就是智能家居。不幸的是，这种显着增强也意味着普通的家用设备（例如冰箱，照相机或什至灯泡）暴露于恶意实体，其主要目的是威胁自动交换信息的机密性，完整性和可用性。为了对智能设备的保护进行微调，本文提出了一种新颖的动态规则管理解决方案，该解决方案适用于物联网环境的当前状态，从而可以保护其免受网络攻击。实验表明，采用这种新颖方案可以显着减少CPU和RAM的消耗。另外，每秒处理的数据包数量大大增加，从安全角度来看也引起了有意义的增强。
