Home Gateway Security Rules for Malicious IoT Device Containment

The patent introduces a gateway as an intermediary device between connected objects and the local network. The gateway implements a security management system that acts as a mediator to filter, monitor, and control communications from connected objects before they reach other network devices. This intermediary mechanism protects the gateway itself and the broader network from malicious activities while still allowing legitimate communications to pass through.

The patent implements preliminary security actions by establishing security rules and policies before malicious attacks can occur. The gateway pre-configures security management systems, defines communication restrictions, and sets up monitoring mechanisms in advance. When devices connect, their communications are immediately subject to these pre-established security measures, preventing potential damage before it can occur to the gateway or network.

The patent implements a universal security management system at the gateway that handles multiple functions simultaneously. The gateway's security management system universally applies to all connected objects regardless of their type or purpose. It performs multiple functions including authentication, authorization, monitoring, and enforcement of security rules for diverse devices (smartphones, tablets, sensors, cameras) through a single integrated mechanism, reducing the need for separate security systems for each device type.

The patent utilizes parameter changes to manage security dynamically. The security management system adjusts security parameters such as communication limits, data transmission rates, and access permissions based on the device type, connection status, and observed behavior. These parameter changes allow the system to adapt security measures to different scenarios without requiring complete reconfiguration, simplifying the management of complex security requirements for multiple diverse devices.
