Prelude Reporting Patch for Snort 1.8.7 and 1.8.6

The Prelude Development Team ( is proud
to announce the availability of the experimental patch for Snort
( allowing integration between Snort and Prelude

Prelude IDS is a modular hybrid intrusion detection system, available
under the GNU GPL licence. An interesting feature of Prelude is the
IDMEF-based messaging system allowing exchange of alerts between the
components of the system. The design of the messaging system allows
integration with third-party applications by making them capable of
sending alerts in the common format using the libprelude library. This
provides the capability of centralized processing and logging of alerts
emmited by various sensors, both host- and network based.

Although Prelude is equipped with it's own NIDS component (Prelude-NIDS)
due to widespread usage of Snort we have decided to try to provide the
capability of using Snort along with other Prelude components.

Technically speaking our patch adds a new output module for
Snort, which handles sending alerts to Prelude Manager, using the
functionality provided by libprelude, such as SSL-based connections and
asynchronous(threaded) I/O handling. It must be noted that the patched
Snort will work only on systems that are capable of running libprelude.

This release is considered by us to be experimental, i.e. it may be not
complete and stable enough for production usage. If you however want to
try it at your own risk, you are welcome.

Currently, patches are available for Snort version 1.8.7 and 1.8.6. It
should be relatively easy to port our patch to any other 1.8.x version.

The patches are available from the Download section of the Prelude
website at , as the tarball named
snort-prelude-reporting-patch-0.1.0.tar.gz . The MD5 hash of the tarball
is 5570eaad8efd7eb0191784412b5913da.
