Compile the module passing --with-python option to the ./configure script if you

|
|||
for example, for reading the alerts stored in the history file, in the
|

database, the current correlations, and so on.
|
||||
|
||||
It is also possible to write your own modules in Python language. See the file
|
||||
'example.py' in corr_modules/ for a quick overview. All you need to do is to
|
||||
declare in your module the functions AI_corr_index (taking two arguments, two
|
||||
alert descriptions) and AI_corr_index_weight (taking no argument),
|
||||
both returning a real value descibing, respectively, the correlation
|
||||
value between the two alerts and the weight of that index, both between
|
||||
0 and 1. You can also access the alert information and all the alerts
|
||||
acquired so far by the module by importing in your Python code the
|
||||
'snortai' module. You can compile it and install it by moving to
|
||||
'pymodule/' directory and running
|
||||
|
||||
$ python setup.py build
|
||||
$ [sudo] python setup.py install
|
||||
|
||||
You can acquire the current alerts by writing a code like the following:
|
||||
|
||||
import snortai
|
||||
|
||||
alerts = snortai.alerts()
|
||||
|
||||
for alert in alerts:
|
||||
# Access the alerts information
|
||||
|
||||
The fields in the alert class can be viewed in pymodule/module.py and
|
||||
corr_modules/example.py examples. Take these files as guides for interfacing
|
||||
your Python scripts with SnortAI module or writing new correlation modules in
|
||||
Python.

Python module for interfacing with SnortAI. Compile it and install it through
|
||||
|
||||
$ python setup.py build
|
||||
$ [sudo] python setup.py install
|
||||
|
||||
You can then access the alerts information captured by Snort simply by writing a
|
||||
code like the following (also see module.py):
|
||||
|
||||
import snortai
|
||||
|
||||
alerts = snortai.alerts()
|
||||
|
||||
for alert in alerts:
|
||||
# Access the information
|
||||
|
||||
The alert class has the following members:
|
||||
|
||||
# id, gid, sid, rev, description, priority, classification, timestamp
|
||||
# from, to, from_port, to_port, latitude, longitude, alerts_count
