[0040] The technical scheme of the present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments, so that those skilled in the art can better understand the present invention and implement it, but the examples given are not intended to limit the present invention.
[0041] Abnormal behavior detection methods based on user access sequences, such as figure 1 shown, including the following steps:
[0042] Step 1. Corresponding data preprocessing module: grab data from the local network, preprocess the data, and serialize the obtained data;
[0043] Step 2, corresponding sequence pattern mining module: store the sequence formed in step 1 into the sequence database, and generate the behavior sequence of each user based on time;
[0044] Step 3. Corresponding abnormal behavior detection module: Calculate the behavior similarity and correlation coefficient between users through the behavior sequence of each user, c...
