Embodiment Construction
[0023] The following examples will further illustrate the present invention.
[0024] Embodiments of the present invention include the following steps:
[0025] 1) The defense system quantifies the scanning time interval x into 10 levels, x∈X=[0.1,0.2,...,1]. At the same time, observe the attack time interval and duration of the cloud storage device being attacked, and quantify the attack interval y and duration z into 10 levels, y∈[0.1,0.2,..,1], z∈[0.1,0.2 ,..,1]. The defense system provides detection services for all cloud storage devices on the cloud platform, and independently selects a scanning interval for each cloud storage device.
[0026] 2) Initialize the Q value matrix to 0, and the Q value matrix is Q(s,x), which represents each available state s of the defense system, and assigns a corresponding Q value to all optional scanning time intervals x; where the defense system The state s of the state is the sum y+z of the attack time interval and duration of the p...
