An automated method for cyberattack detection and prevention in an endpoint. The technique monitors and protects the endpoint by recording inter-process events, creating an inter-process activity graph based on the recorded inter-process events, matching the inter-process activity (as represented in the activity graph) against known malicious or suspicious behavior (as embodied in a set of one or more pattern graphs), and performing a post-detection operation in response to a match between an inter-process activity and a known malicious or suspicious behavior pattern. Preferably, matching involves matching a subgraph in the activity graph with a known malicious or suspicious behavior pattern as represented in the pattern graph. During this processing, preferably both direct and indirect inter-process activities at the endpoint (or across a set of endpoints) are compared to the known behavior patterns. The approach herein provides for systematic modeling of inter-process behaviors for characterizing malicious or suspicious patterns among processes.

The invention relates to a method for compiling a source code to a program code, the method comprising: providing (101) a pattern graph based on the source code, the pattern graph corresponding to an intermediate representation of the source code according to a set of rules in a first programming language, wherein the set of rules comprises a specific replacement rule directing a pattern graph to be replaced by a corresponding replacement graph assigned to the pattern graph, replacing (103) the pattern graph by the replacement graph assigned to the pattern graph, and generating (105) the program code based on the replacement graph.

The invention discloses a ship-based segmented logistics mode mining and visualization method and system, and the method comprises the steps of collecting the ship segment original logistics data, andgenerating a ship segment logistics transportation original data table; preprocessing the original ship segment logistics transportation data table to generate a ship segment logistics feature vectorof each ship segment; carrying out the hierarchical clustering analysis on the multiple ship segment logistics feature vectors to generate a clustering tree diagram, and generating the multiple shipsegment categories and ship segment sets corresponding to the multiple ship segment categories according to the clustering tree diagram; and performing statistical analysis and normalization processing on the set and logistics transportation original data tables to generate a logistics mode feature statistical table, and drawing a ship segment logistics mode graph of a plurality of ship segment types according to the feature statistical table. According to the method, problems existing in an existing ship section logistics mode can be obtained, and the discovered problems are analyzed or solved in a targeted mode by combining the characteristics of specific ship sections corresponding to each logistics mode.
