Using Genetic Algorithms for Network Intrusion Detection and Integration into nProbe
Conference: OSCON 2010 Presentation Link: Ignite Track Presented by: Brian Lavender SNORT is popular Network Intrusion Detection System (NIDS) tool that currently uses a custom rule based system to identify attacks. This presentation emphasizes on writing the algorithm to write generate the rules through GA and the integration of them into nProbe, a similar network monitoring tool written by Luca Deri with a plug-in architecture. Genetic Algorithms are dependent upon identifying attributes to describe a problem and evolving a desired population. In this case, the problem is an attack through the …

Modern Packet Capture and Analysis: Multi-Core, Multi-Gigabit, and Beyond
Sometimes people ask me a tutorial about PF_RING. Last year I have given a tutorial about it at the IM 2009 conference. I think that everyone interested in using PF_RING for going beyond packet capture acceleration should read this set of slides I used for the tutorial. Today the cost of packet capture is limited with respect to packet analysis. For this reason you should use PF_RING as a framework for creating simple yet powerful traffic monitoring applications. …

Interview with Luca Deri
In this video Luca presents the ntop project and gives an outlook of future activities. It was presented during the OSS conference that took place last May in Bolzano. Finally this short interview gives an idea of how ntop can benefit when integrated with commercial applications and vendors such as Würth-Phoenix. …

nProbe with FastBit database: an innovative flows storage solution
nProbe, acronym for NetFlow probe, is an open-source probe that supports both NetFlow and sFlow collection. It has been designed to keep up with Gigabit speeds on commodity hardware and it can be used for capturing packets and analyzing networks at full speed with no (or very moderate) packet loss using PF_RING. Each captured packet is analyzed, associated to a flow record, and periodically, the expired flows are emitted and exported to the specified collectors. nProbe is fully inter-operable with commercial collectors and open source tools such as ntop. The …

ntop and Plixer Partnered for Advanced Flow-based Monitoring
May 17th 2010 Press Release Plixer International, Inc., a leading global provider of network traffic monitoring and analysis tools, today announced that it has partnered with NTOP of Italy to launch Scrutinizer 7.7 with nProbe™ support for advanced flow-based monitoring to analyze client, server and application latency. If the flow involves HTTP, the URL information can also be exported. With its unique software-based nProbe™ support, Scrutinizer 7.7 is the first-of-its-kind NetFlow analyzer to enable affordable remote probe deployment on individual PCs or servers to track and pinpoint traffic and application …

Extending ntop using Python
ntop was designed to be self-contained in order to avoid people configuration and usage headache. Unfortunately the drawback is that extending ntop has always been a difficult activity as users had to code in C and know ntop’s internals. Recently thanks to the integration of ntop with Python, it is possible to script the application and add new features on the fly with minimal effort and no knowledge of how ntop works internally. This tutorial shows how the ntop+Python integration works, and it describes what users can do with it. …

Meet ntop @ Florence (May 9th): Opening-up ntop using Python
Pycon Conference Florence, May 7-9 2010 ntop (https://www.ntop.org) is an open-source project aimed at monitoring network traffic. Recently, in order to make the tool even more flexible than before this for letting people adapt it to their needs, the python interpreter has been embedded into ntop. The result is that users can now use python for scripting ntop or building monitoring applications in python leveraging the ntop monitoring engine. This talk presents the ntop/python integration and describes some real network monitoring problems that have been effectively solved using this solution. …

Meet ntop @ Zürich (June 23rd): Large-scale Flow Monitoring Through Open Source Software
AIMS 2010 Conference Tutorial Zürich, June 21-25, 2010 Large and high-speed networks produce a large number of flows that need to be collected and analyzed. Most collectors are unable to keep up with the flow export rate, and also have severe speed limitations when creating reports, due to the amount of data that needs to be analyzed. This tutorial shows how recent innovation in databases, combined with existing open-source software applications, allow flow collection and exploration of large-scale flows to become feasible. Furthermore the use of web 2.0 technologies enable …

10 Gbit PF_RING-based Hardware Packet Filtering and Balancing Previewed at the Intel Europe Conference
Intel Research Europe Conference, Bruxelles, May 4th 2010 Luca Deri and Joseph Gasparakis, senior Intel engineer, have previewed a new PF_RING-based technology they have co-developed that allows Linux users to fully exploit the hardware capabilities of the newest Intel X520 10 Gbit adapter (based on Intel 82599 controller). This technology that is close to public availability (at no cost), will enable PF_RING users to program the X520 card with (over 32’000) rules that allow to both balance and filter traffic in hardware with no CPU intervention. Linux users will be …
