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

Sguil is a graphical

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.

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 ...
