Abstract
A method is provided for detecting intrusions to a computing environment. The method includes: monitoring system calls made to an operating system during a defined period of time; evaluating the system calls made during the defined time period in relation to system calls made during known intrusions; and evaluating the temporal sequence in which system calls were made during the defined time period when the system calls made match the system calls made during a known intrusion. If a potential intrusion is detected at this stage, then a more complicated detection scheme may be performed by a second detection scheme. For instance, the second detection scheme may assess the temporal sequence in which the system calls were made and/or the system files accessed by the system calls.
