Explanation

A router operates at OSI Layer 3 (Network Layer) and is the device responsible for connecting different networks-specifically, connecting a Local Area Network (LAN) to the Internet by routing IP packets between them. A SIEM (Security Information and Event Management) is a monitoring and logging platform. A Firewall provides traffic filtering but is not the primary device for network interconnection. A HIDS (Host-based Intrusion Detection System) monitors activity on individual hosts. Only a router fulfills the core function of inter-network connectivity.
