Raffael Marty - Sophos | July 22-23 & July 24-25


Big data and security intelligence are two very hot topics in security. We are collecting more and more information from both the infrastructure, but also directly from our applications. This vast amount of data gets increasingly harder to understand. Terms like map reduce, hadoop, spark, elasticsearch, etc. are part of many discussions. But what are those technologies? And what do they have to do with security intelligence? We will see that none of these technologies are sufficient in our quest to defend our networks and information. Data visualization is an approach that scales to the ever changing threat landscape and infrastructure configurations. Using big 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 than conventional methods. The attendees will learn about log analysis, big data, information visualization, data sources for IT security, and learn how to generate visual representations of IT data. The training is filled with hands-on exercises utilizing the DAVIX live CD.

Day 1:

Log Analysis
  • Data Sources Discussion such as PCAP, Firewall, IDS, Threat Feeds, etc.
  • Data Analysis and Visualization Linux (DAVIX)
  • Log Data Processing (CSVKit, ...)

Log Management and SIEM
  • Log management and SIEM overview
  • Elastic Stack and Moloch
  • Big data - Hadoop, Spark, ElasticSearch
  • Data Science with R

Day 2:

  • Visualization Theory
  • Dashboard design
  • Data Visualization Tools and Libraries - e.g., Mondrian, Gephi, AfterGlow
  • Visualization Resources

Security Visualization Use-cases
  • Perimeter Threat
  • Network Flow Analysis
  • Firewall Visualization
  • IDS/IPS Signature Analysis
  • Vulnerability Scans
  • Proxy Data
  • User Activity
  • Host-based Data Analysis
