Real-Time Monitoring
Use Sguil’s advanced GUI to monitor and analyze IDS events in a timely manner.
One thing that’s crucial
when analyzing your IDS events is to be able to correlate all your
audit data from various sources, to determine the exact trigger for
the alert and what actions should be taken. This could involve
anything from simply querying a database for similar alerts to
viewing TCP stream conversations. One tool to help facilitate this is
Sguil (http://sguil.sourceforge.net), the
Snort GUI for Lamerz. In
case you’re wondering, Sguil is
pronounced “sgweel” (to rhyme with
“squeal”).
Sguil is a graphical
analysis console written in Tcl/Tk that brings together the power of
such tools as Ethereal (http://www.ethereal.com),
TcpFlow (http://www.circlemud.org/~jelson/software/tcpflow/),
and Snort’s portscan and TCP stream decoding
processors into a single unified application, where it correlates all
the data from each of these sources.
Sguil
uses a client/server model and is made up
of three parts: a plug-in for Barnyard
(op_guil), a server
(sguild), and a client
(sguil.tk). Agents installed on each of your
NIDS sensors are used to report back information to the
Sguil server. The server takes care of
collecting and correlating all the data from the sensor agents, and
handles information and authentication requests from the GUI clients.
Before you begin, you’ll need to download the
Sguil distribution from the project’s web site and unpack it somewhere. This will create a ...
