VizSEC 2008 Workshop on Visualization for Cyber Security
September 15, 2008 / Cambridge, MA USA
In conjunction with RAID 2008
The 5th International Workshop on Visualization for Cyber Security will provide a forum for new research in visualization for computer security. We are pleased to be holding this year's meeting in conjunction with the 11th International Symposium on Recent Advances in Intrusion Detection. The VizSEC Workshop will be held at MIT in Cambridge, Massachusetts USA on Monday, September 15, 2008.
As a result of previous VizSEC workshops, we have seen both the application of existing visualization techniques to security problems and the development of novel security visualization approaches. However, VizSEC research has focused on helping human analysts to detect anomalies and patterns, particularly in computer network defense. Other communities, led by researchers from the RAID Symposia, have researched automated methods for detecting anomalies and malicious activity.
The theme for this year's workshop, which will be held in conjunction with RAID 2008, will be on bridging the gap between visualization and automation, such as leveraging the power of visualization to create rules for intrusion detection and defense systems. We hope that VizSEC participants will stay for the RAID Symposium and RAID participants will consider coming a day early to participate in VizSEC.
We also solicit papers that report results on visualization techniques and systems in solving all aspects of cyber security problems, including:
* Visualization of Internet routing
* Visualization of packet traces and network flows
* Visualization of intrusion detection alerts
* Visualization of attack tracks
* Visualization of security vulnerabilities
* Visualization of attack paths
* Visualization of application processes
* Visualization for forensic analysis
* Visualization for correlating events
* Visualization for computer network defense training
* Visualization for offensive information operations
* Visualization for building rules
* Visualization for feature selection
* Visualization for cryptology
* Visualization for detecting anomalous activity
* Deployment and field testing of VizSEC systems
* Evaluation and user testing of VizSEC systems
* User and design requirements for VizSEC systems
* Lessons learned from development and deployment of VizSEC systems
All submitted papers will be peer-reviewed. Full and short papers from the workshop will be published in an edited book (details to follow).
Full papers should present mature research results. (We will release page count and formatting instructions when we confirm the details of publishing the proceedings.)
Short papers can be used to present less mature research results than full papers, or late-breaking results. (We will release page count and formatting instructions when we confirm the details of publishing the proceedings.)
Demonstrations can be used to show new or updated development efforts. Demo submissions should consist of a 2 page abstract.
Posters can be used to describe work in progress or updates to previously published VizSEC research or R&D. Poster submissions should consist of a 2 page abstract.
April 11, 2008 : Deadline for full paper submission
May 9, 2008 : Deadline for short paper submissions
July 11, 2008 : Deadline for poster and demo abstracts
The image shows a Nmap scan. It covers the middle half of class C network range (.64 to .192) and at the same time probes the popular ports at each address. It is a parallel network and port sweep with decoys to hide the true identity of the scanner - so it simultaneously address scans and port scans while spoofing other source addresses to obscure the scanners identity. The scan was generated by the Nmap command below:
nmap -sS 127.21.146.64-192 -e lo -F -T5 --host-timeout 10m --max-retries 0 --initial-rtt-timeout 25ms --max-rtt-timeout 250ms --max-scan-delay 250ms --scan-delay 10ms --min-hostgroup 32 --max-hostgroup 32 -D 188.8.131.52,184.108.40.206,220.127.116.11
In summary, the command tells Nmap to SYN scan the middle half of the loop-back network (-sS 127.21.146.64-192 -e lo) on common ports (-F) in a non-random manner (-r), and scan in parallel address blocks of 32 (--min-hostgroup 32 --max-hostgroup 32) while creating decoy packets with 3 spoofed addresses (-D 18.104.22.168,22.214.171.124,126.96.36.199).
The data is visualised in IneVis, a time-animated interactive 3-D packet trace visualisation. InetVis supports, IP ICMP, TCP, and UDP. Essentially, it's a 3-D scatter-plot:
In the sample image, the lines are 'sweeping' across popular ports at each address (in the direction of the blue axis). Note the concentration in the lower port range (bottom green axis) where most common service ports reside. The four identical 'columns' of activity are the sources (separated by red-axis). One of these is the true scanner, the other's are spoofed decoys. The image is shown with a 45 minute time-window and 'transparent' ageing which makes older packets fainter. The chosen colour scheme is by destination port.
InetVis was inspired by Stephen lau's Spinning Cube of Potential Doom. For more details about InetVis, see: http://www.cs.ru.ac.za/research/g02v2468/inetvis.html.
currently I am searching for a nice tool (OSS/commercial) to do some jobs on my checkpoint firewall rules (cpdb2html generated a 348 page file):
1. Aggregation of rules - Let's say every server in a subnet has ssh enabled then I would like to create ONE rule for the whole environment and remove the dupes.
2. Visualization - I'd like to have a nice graph of my subnets where I can see the hosts and the ports which are openend.
I am no firewall administrator and I only saw the checkpoint GUI once - so maybe I am missing something obvious here.
Thanks and Kind Regards,

I came across this presentation from Tamara Munzner. A great read about some of her latest research in visualization. Here are the tools the presentation references. They are really interesting and if you look around on Tamara's Web page, you will find some videos and the tools themselves.
Recently I've stumbled upon this interesting little app called glTail , it's pretty bare at the moment but there's potential.
As I don't like duplication of the post, the detail explanation of the graph can be found at security.org.my here.
AfterGlow 1.5.9 is out. It's not a huge release, but it allows for some new things that, for example, Tenshi needed to make it more useful. The feature that helps there is that you can now dynamically change node labels.
Another new feature is the addition of URLs to nodes. This is needed to support image maps. If you generate an image map through GraphViz (-Tcmapx), you can provide URLs that go along with the nodes. If you then use that image map in an HTML file along with the graph, you have an interactive graph. If you are interested in how this looks, I blogged about a Splunk - AfterGlow integration on my Splunk blog. The new search command I built, is using image maps to build an HTML file, which is then linked back to Splunk. Check it out.
I wanted to see if I could hook up Tenshi, a log monitoring application, with some pretty graph, for a long time. The current tree supports a csv output feature that allows pipeing to something like AfterGlow.
In order to get this you can use something like this in your tenshi configuration (if you use the latest version from the tree):
set csv [0 * * * *] /usr/local/bin/tenshi_graph.sh
Where tenshi_graph.sh could be
/usr/local/bin/afterglow.pl -c /etc/afterglow.conf -t | neato -v -Tpng -o /var/lib/tenshi/tenshi_graph.png
and afterglow.conf configuration could be something like
color.target="red" if ($fields > 1000);
color.target="orange" if ($fields > 500);
color.target="blue" if ($fields > 100);
color.target="lightblue" if ($fields > 50);
color.target="yellow" if ($fields == 1);
This allows having target node colours depending on the number of hits of the affected log, but of course it might be whatever conditions you want. You can see how it's possible to quickly evaluate logs that are common to different servers and their frequency.
Keep in mind that in order to have useful and readable graphs your tenshi configuration must be accordingly tuned. Arbitrary logs in the csv queue would quickly generate huge and unreadable node maps.
This is just an example, more advanced processing can be done. If you have new ideas please share them on firstname.lastname@example.org mailing list and/or the SecViz portal :).
I’ve wanted to post this graph for a while but only just got round to anonymising the data.
Looking at piles of IRC logs can be very unilluminating, but it’s not obvious what to do with all the data. One nice way of getting a handle on links between channels is to plot channels with links between them weighted by the number of users in common.
The example above is from a honeynet we ran in 2004/5. The graph shows up a couple of things nicely:
1) There are two distinct groups of channels, and a look at the data shows that there two groups correspond to channels in different languages and,
2) The strong links between a couple of channels in the main group show up that these channels are related and looking at the data shows them to be used for discussing hacking, while the other channels are innocuous.
The original channel names have been replaced by ‘cN’ to protect the guilty.
