US Patent 11985163 Security appliance

A security appliance may incorporate a touch screen or similar input/output interface, providing command and control over network functionality and configuration, without requiring log in via a network from another computing device. During denial of service attacks, commands from the local interface may be given priority access to processing resources and memory, allowing mitigating actions to be taken, such as shutting down ports, blacklisting packet sources, or modifying filter rules. This may allow the security device to address attacks without having to be manually rebooted or disconnected from the network.
