Re: New HIPS based on SELinux

[Hramchenko <hramchenko@bk.ru>]

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.
