Table 16 Scenario 3-novel hybrid attack (Low-volume DDoS + Packet injection).

From: A hybrid deep learning model for detection and mitigation of DDoS attacks in VANETs

Epoch

System Response

Outcome

Epoch 2

Low anomaly score → No action taken

 − 2 (failed to block early hybrid attack)

Epoch 8

Anomaly accumulation recognized → Monitor node

Better detection of slow-building threats

Epoch 15

Detected correlation across nodes → Block and reroute

 + 1 (successfully mitigated attack)
