Mobile security file leakage detection method and system

A method of detecting mobile security file leakage, comprising:

• receiving, by a detection server, an operating system type from a mobile device;
• connecting, by the detection server, to the mobile device depending on an operating system to load a media file system;
• checking an analysis setting time by the detection server connected to the mobile device;
• analyzing, by the detection server, the media file system to detect presence or absence of an abnormality;
• generating, by the detection server, an analysis result based on presence or absence of an abnormality;
• checking whether there is an error in the analysis result and extracting an original file and a thumbnail file if there is no error by the detection server;
• deleting, by the detection server, a file from which an abnormality is detected based on the analysis result;
• and
• generating and storing a result report on the analysis result by the detection server,
• wherein the operating system type is at least one of a first operating system and a second operating system, and the analyzing, by the detection server, the media file system to detect presence or absence of an abnormality comprises:
• when the operating system type received from the mobile device is the first operating system, performing, by the first operating system, general analysis to analyze directory files, application-specific directories, and deleted data in the media file system;
• performing, by the first operating system, detailed analysis to analyze a file system and logs in the media file system;
• performing, by the first operating system, hidden analysis to analyze DB files, DB logs, and a security folder in the media file system;
• and
• detecting, by the first operating system, presence or absence of an abnormality through analysis content of at least one of the general analysis, detailed analysis, and hidden analysis.
