Abstract: A method for predicting a network attack action, including: monitoring a network status parameter and obtaining information of an attack action according to a change of the network status parameter; selecting a subsequent attack action which has a most possibility to happen from a plurality of subsequent attack actions of the attack action according to a correspondence between the attack action and the plurality of subsequent attack actions, the subsequent attack action which has the most possibility to happen being a subsequent attack action with a largest occurrence number among the subsequent attack actions corresponding to the attack action; and outputting the subsequent attack action which has the most possibility to happen as a predicted network attack action. A device for predicting a network attack action including an attack action management unit is also provided.
