Intrusion Detection System for Wireless Sensor Networks improved with active reactions to incoming attacks

TinyWIDS++ is an Intrusion Detection System (IDS) specific for Wireless Sensor Networks (WSN). It targets low-resource hardware devices and provide an lightweight detection mechanism based on modelling attacks via Weak Process Models. During the normal software application execution, TinyWIDS++ maps the node state on the model by collecting the events (called "observables") that the hardware/software platform generate. Once TinyWIDS++ detects a "dangerous" state, it sends a notification and a callback that allows developers to setup a countermeasure action.

TinyWIDS++ improves TinyWIDS and introduces a new core functionality: active reactions to intrusions. Active reactions will make available a selection of counter-moves (active reactions) (aimed to delay, deter, locate or eventually block incoming intrusions in the WSN. The active reactions will be triggered by the WPM state estimation process and will act while the WSN operations (who will receive an intrusion notification) are on the way to perform on-field operations. The operators will be also provided with additional information (e.g., locations and IDs of the affected WSN nodes) retrieved by the active reactions, which could be helpful as forensic evidence to determine the source or vulnerability exploited by the intrusion.  The active reactions will be selectable and customizable
