4 results about "Program tracing" patented technology

Disclosed herein are devices, systems, and methods for detecting, understanding, and classifying malicious actions and / or behaviors in software (e.g., malware), including hidden malicious actions. Specifically, disclosed embodiments use natural language approaches to understand malicious software and provide explanations for classification results. At least one embodiment constructs a knowledge graph that includes textual explanations from source materials (e.g., articles), collecting one or more sets of dynamic program traces from one or more instances of malware, and constructing and training a model (also referred to herein as Trace-BERT) using the one or more sets of dynamic program traces. Forced execution of sample segments of computer code can also be used to identify hidden or novel malicious actions.

The present invention provides a method for accessing computer system resources based on a user entity, including: S1: obtaining the initial access permission range of the user entity in the system resource memory block; S2: building a program trace tree based on all program operation trace data of the user entity obtained recently within a preset period; S3: determining a reference program trace tree of the user entity in the current running environment based on the environmental deviation data between the current running environment and the standard running environment of the user entity; S4: updating the initial access permission range in real time based on the feature deviation between the program trace tree and the reference program trace tree to obtain the current access permission range; S5: generating an access feedback result based on the access request instruction of the user entity and the current access permission range; for analyzing the deviation of the running environment of the user entity and the program operation trace data, realizing real-time dynamic adjustment of the access permission range of the system resources, and making the security degree of the system resource access process higher.

The invention belongs to the technical field of query language execution, and particularly relates to a structured query language tracking method, device and system in a micro-service environment, and the method comprises the steps: obtaining a program tracking parameter of a current user; generating a program tracking context corresponding to the user request; responding to the user request, and generating tracking data I about the user request; creating tracking data II, updating the tracking data ID in the program tracking context again according to the tracking data II, and updating the parent tracking data ID in the program tracking context according to the tracking data I; updating the tracking data II according to the end time of the calling operation to generate complete tracking data; and sending the complete tracking data to a program tracking center, and recovering the tracking data ID in the program tracking context based on the tracking data I after the complete tracking data is sent. Problems can be quickly positioned and solved, and service loss caused by system faults or performance problems is reduced.
