An efficient security framework, vulnerabilities, and defense mechanisms in LoraWAN

<p>The rapid expansion of cloud computing within business environments, along with the increasing complexity of organizational deployments, has led to a surge in cloud-based attacks on computer networks. These attacks exploit security vulnerabilities and systemic breaches. This study explores robust defense mechanisms by leveraging policy-based configurations and rule enforcement on edge network devices. These mechanisms were tested using GNS3 simulations to strengthen internal and external infrastructures against critical threats such as ICMP, CDP, and port security attacks.</p>
