The invention discloses a method for acquiring a predicted attack path of a power network. The method comprises the following steps of acquiring initial weight values of attack path influence factorsaccording to the attack path influence factors, wherein at least two attack path influence factors are provided; acquiring the predicted attack path according to the attack path influence factors andthe initial weight values of the attack path influence factors; adjusting the initial weight values according to the acquired predicted attack path and a recorded actual attack path; and correcting the predicted attack path according to the attack path influence factors and the adjusted initial weight values. Therefore, the prediction of the attack path for the power network is realized, and the weight values of the attack path influence factors are dynamically adjusted according to the actual attack path, so that the predicted attack path is more accurate, and false alarms and missed alarms are reduced.
