Preventing APT attacks on LAN networks with connected IoT devices using a zero trust based security model

Many organizations are being targeted by different types of attacks. One of the most dangerous attacks is called Advanced Persitent Threats (APT) as it is silent and focused on espionage and information theft, unlike a denial of service (DoS) attack. The proposed solution addresses the implementation of a security model based on zero trust in order to prevent APT attacks on LAN networks. The proposal is to use the concepts of micro-segmentation and Next-Generation Firewalls (NGFWs). Many IoT devices are present in most networks and most of them have several vulnerabilities that can facilitate the theft of information and compromise the local network.
