Abstract: One or more embodiments relate to a security setting device, a method of setting a per-process security policy, and a computer program stored in a recording medium to execute the method, and more particularly, to a security setting device configured to protect an electronic device from external attacks to a program by performing static analysis with respect to the program to set security policies for processes included in the program and monitor whether there have been violations on the security policy, a method of security setting, and a computer program stored in a recording medium to execute the method.

Abstract: Methods and systems for security analysis include determining whether a process has an origin internal to a system or external to the system using a processor based on monitored behavior events associated with the process. A security analysis is performed on only processes that have an external origin to determine if any of the processes having an external origin represent a security threat. A security action is performed if a process having an external origin is determined to represent a security threat.

Abstract: A computer-implemented method for performing privilege flow analysis is presented. The computer-implemented method includes monitoring at least one program operating system (OS) event handled by a program, generating a privilege flow graph, determining an inferred program behavior context, and generating, based on a combination of the privilege flow graph and the inferred program behavior context, an inferred behavior context-aware privilege flow graph to distinguish different roles of processes and/or threads within the program.

Abstract: A computer-implemented method for analyzing operations of privilege changes is presented. The computer-implemented method includes inputting a program and performing source code analysis on the program by generating a privilege control flow graph (PCFG), generating a privilege data flow graph (PDFG), and generating a privilege call context graph (PCCG). The computer-implemented method further includes, based on the source code analysis results, instrumenting the program to perform inspections on execution states at privilege change operations, and performing runtime inspection and anomaly prevention.
