  Safe and secure electric vehicle charging stations (EVCSs) are important in
smart transportation infrastructure. The prevalence of EVCSs has rapidly
increased over time in response to the rising demand for EV charging. However,
developments in information and communication technologies (ICT) have made the
cyber-physical system (CPS) of EVCSs susceptible to cyber-attacks, which might
destabilize the infrastructure of the electric grid as well as the environment
for charging. This study suggests a 5Ws \& 1H-based investigation approach to
deal with cyber-attack-related incidents due to the incapacity of the current
investigation frameworks to comprehend and handle these mishaps. Also, a
stochastic anomaly detection system (ADS) is proposed to identify the
anomalies, abnormal activities, and unusual operations of the station entities
as a post cyber event analysis.
