Generating alerts is not Anomaly Based analysis, it is simply generating
alerts based on SELinux logs,
This is in no way fit into any definition of HIPS/HIDPS as security
industry defines it.
There is no such deterministic or non-deterministic statistical analysis
going on here, that you put your program into that category, those are
based on established Math actually, We use Advanced Statistical Math in
Anomaly analysis (in item 2: anomaly analysis you referred it to) taking
into account system factors and components

Hello, Patrick
Thanks for your reply. I understand your concerns about the term of HIPS.
I didn't want to mislead users, but User Data Defence is not new another
policies editor.
User Data Defence also provides customizable alerts notification. User could
specify alert look and set its level. This function helps to filter critical
alerts from other messages.
I think alerts notification provides detection of program anomalies:
2) Anomaly based analysis of threats against the server, in example
statistical analysis, Integrity analysis and etc.
Of course, User Data Defence is not so powerful as chkrootkit HBIDS, but it is
an attempt to provide simple instrument for blocking attacks to user mode
applications.

Hello,
I think you are misusing the term "HIPS" here, (or using your own
definition actually)
Sorry to be pedantic but, SELinux as you know is an add-on (platform
) to the kernel providing Access Control (RBAC, IBAC, MAC and etc.) and
MLS (Multi-Level Security)
While encouraging you for your work but I'm afraid it is as you
explained yourself:
" User Data Defence includes set of template policies, which makes
process of creation SELinux specifications for user mode applications
simple .... "
in other words, It is A Graphical user Interface for creating SELinux
Policies
BUT, Host based Intrusion Prevention System, (HIPS)
or more accurately Host Based Intrusion Detection and Prevention System
(HIDPS) requires a method to detect attacks and react upon them or
interact with them (Preemptive approach), taking into account the server
or workstation parameters and conditions, utilizing either or
combination of :
1) Signature based analysis of threats
2) Anomaly based analysis of threats against the server,
in example statistical analysis, Integrity analysis and etc.
3) Protocol Anomaly Analysis
4) Heuristic analysis
combination of methods using Expert systems or other means in
Artificial Intelligence/Synthetic Intelligence such as Petri nets,
Artificial Neural Networks and etc.

Hi all.
I have created new host intrusion prevention system based on SELinux.
It's focused on protection user's data.
One of the main goals was to create lightweight replacement of
setroubleshootd.
I hope my program will be useful for SELinux users.
