A simulated packet stream hitting a firewall — each packet is scored against a set of traffic-shape rules (unusual size, odd port, bursty timing), and flagged as normal or malicious in real time. It's a toy version of the kind of anomaly-detection logic behind intrusion detection systems, the same space my thesis work sits in.

A small feedforward network — input, two hidden layers, and an output layer classifying traffic as normal, suspicious, or malicious. Each cycle, a random input vector is pushed through: watch the signal pulses travel edge by edge, node glow track activation strength, and edge thickness/color track weight magnitude (teal/green = positive, red = negative). A simplified picture of the kind of network behind intrusion detection models.
