Hello,
> Statistical analysis is not requirement
There are 4 established methods for IDS and IPS detection part of the
IDPS system, your IDS/IPS should have at least one :
1) Signature based
2) Anomaly Analysis
3) Protocol Analysis
4) Heuristic Analysis
The problem is yours doesn't have any, it is reporting SELinux Logs only
by alerts,
You want to teach me my profession no problem,
I answered it before,
You are wasting time here,
Your so called "HIPS" only sends alerts of SELinux Logs, Period.
If you call this HIPS I don't care, I just clarified that it is not in
my opinion. Otherwise we have to call all log watcher daemons HIPS then.
A bicycle has wheels, a car has wheels too, but surely a bicycle is not
qualified as a Car due to just having wheels, Otherwise my firecrackers
would be the Saturn 5 Missiles (same physics)
Your program just reports SELinux Logs and sends alerts, it uses some
Templates for establishing SELinux Policies,
There is no element of interaction or reaction to threats by detecting
and responding in it, and There is no extensive system analysis of 4
types as I mentioned above,
In Example, Snort IDS Uses Signature based analysis, Bro IDS uses
Protocol Analysis, Commercial ones use Anomaly analysis and Heuristic
Analysis as well,
Your problem is it has been my profession during past 12 years, and you
want to change the definition and call a simple program Host Based
Intrusion Prevention System !!! no problem, You call it what you want,
You post something to the List for other professional peer-review isn't it?
Sir you are using your own definition not the established ones.
Best,

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.

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.
