The concept of malware specification called Malspec. Malspec is a directed acyclic graph (DAG) where each node corresponds to a (relevant) system call invocation and edges represent dependences between arguments of different system calls. Malspec is extracted by contrasting the execution behavior of a known malware against the execution behaviors of a set of benign programs. Authors pointed out that Malspecs do not encode data flow dependencies between system call parameters, and that using Malspecs for detection without verifying these dependencies would lead to a large number of false alarms. Online Journals are scholarly and peer reviewed journals. The journals provide forum and motivates scientists, researchers, academics, engineers, and practitioners in all aspects to share their professional and academic knowledge in the fields computing, engineering, humanities, economics, social sciences, management, medical science, and related disciplines. Online Journals also aims to reach a large number of readers worldwide with original and current research work completed on the vital issues of the above important disciplines.
