Enhancing Security and Privacy Measures in Internet of Things (IoT) Implementations

IoT devices are on the verge of permeating our lives more extensively than mobile phones and will possess access to the most sensitive personal data, including social security numbers and banking information. With the increasing number of devices, security challenges escalate, further complicated by the fact that security solutions often are not compatible with most embedded devices. These devices must ensure the security of stored data, guarantee secure communication, and defend against cyber-attacks. The objective of our paper is to explore how to fortify our IoT device, exemplified by a Raspberry Pi, utilizing a Firewall, IDS, and SSL/TLS. Initially, it will establish a connection with the Losant platform (IoT platform), and we will verify its seamless operation. Subsequently, we will progress with the Raspberry Pi, involving three stages: installing a Firewall, implementing an IDS, and confirming the default presence of the SSL/TLS protocol. Finally, we endeavored to scrutinize the traffic between them to demonstrate that no unauthorized attempt will be made to breach our Raspberry Pi
