gltail: cisco asa parser

worked up a cisco asa parser for gltail ( http://www.fudgie.org/ ) to do firewall movies specific to cisco.

I'll submit to the ruby project for gltail, but if anyone wants it email me at jeff@jeffbryner.com.

Applied Security Visualization - Book

Title: Applied Security Visualization
Author: Raffael Marty
Source: Addison Wesley Professional
Publication Date: July 2008 (estimated)

Excerpt:

'....As networks become ever more complex, securing them becomes more and more difficult. The solution is visualization. Using today's state-of-the-art data visualization techniques, you can gain a far deeper understanding of what's happening on your network right now. You can uncover hidden patterns of data, identify emerging vulnerabilities and attacks, and respond decisively with countermeasures that are far more likely to succeed.

In Applied Security Visualization, leading network security visualization expert Raffael Marty introduces all the concepts, techniques, and tools you need to use visualization on your network. You'll learn how to identify and utilize the right data sources, then transform your data into visuals that reveal what you really need to know. Next, Marty shows how to use visualization to perform broad network security analyses, assess specific threats, and even improve business compliance. He concludes with a thorough introduction to DAVIX, today's leading toolset for security visualization.


  • Intimately understand the data sources that are essential for effective visualization
  • Choose the most appropriate visualization graphs and techniques for your network data
  • Walk step-by-step through transforming complex data into crystal-clear visual representations
  • Iterate your graphs to deliver even better insight for action
  • Assess threats to your network perimeter, as well as threats generated by insiders
  • Use visualization to manage risks more successfully
  • Visually audit both the technical and organizational aspects of network security
  • Compare and master today's most useful tools for network security visualization

Contains the powerful Data Analysis and Visualization UNIX (DAVIX) toolset for visualizing networks and assessing their security. DAVIX runs directly from the CD-ROM, without installation......'

Prelude IDMEF Grapher (PIG) shows IDMEF data on a multi-axes view for graphical alerts analysis. This graph shows what was displayed performing a scan using the Retina software. Snort and Prelude LML (log analysis) send their alerts to the prelude manager that we connect to using pig.

Next, a plot of the same data using the destination port number over time points to obvious port scanning in the form of diagonal lines as well as odd patterns that sync with the previous destination IP address plot.

All of these graphs were created by parsing firewalls logs using a perl script and loading them into Advizor Analyst.

When you plot the destination IP address as an integer over time, many interesting patterns are highlighted. Even more interesting than the horizontal patterns indicating continuous traffic to specific IP addresses are the vertical clusters with regularly repeating frequencies.

All of these graphs were created by parsing firewalls logs using a perl script and loading them into Advizor Analyst.

VizSec 2008 update
