Hello Patrick. Statistical analysis is not requirement for IDPS according to NIST Guide to Intrusion Detection and Prevention Systems (IDPS) by Karen Scarfone and Peter Mell : The types of events detected by host-based IDPSs vary considerably based primarily on the detection techniques that they use. Some host-based IDPS products offer several of these detection techniques, while others focus on a few or one. One of the most important function of HIPS is: – System call monitoring. The agent knows which applications and processes should be calling which other applications and processes or performing certain actions. System call monitoring provided by User Data Defence from SELinux messages. Of course this system need further development and intellectual analysis of events will be appended to this system in the future. But the lack of intellectual analysis does not prohibit refer User Data Defence to intrusion prevention systems. With respect, Hramchenko Vitaliy.
