Method and system for security detection

An embodiment of the invention discloses a method and a system for security detection. The method includes: a, performing security scanning on codes of an application program, determining the application program as a highly dangerous application program and generating detection results if high dangerousness is detected, and executing step d, otherwise executing step b; b, analyzing codes of the application program, and generating analyzing results; c, performing detection judgment on the basis of the analyzing results, judging security of the application program, and generating detection and judgment results; d, storing the detection results or the detection and judgment results and forming security level data. The system comprises a vulnerability detection module, an analyzing module, a detection and judgment module and a database. By means of the method and the device for security detection, vicious application programs can be fast detected from a large number of application programs, risk levels of the application programs can be provided, users can easily know about high-risk application programs and avoid using the high-risk application programs, loss is reduced, and application markets can be managed in a standard mode.
