Think network forensics is just for security? Not with today’s 10G (and tomorrow’s 40G/100G) traffic, not to mention new 802.11ac wireless networks with multi-gigabit data rates. Data is traversing these networks so quickly that detailed, real-time analysis is at best a challenge. Network forensics provides key real-time statistics while saving a complete, packet-level recording of all network activity. You don’t need to worry about capturing the problem – your network forensics solution already has, allowing you to go back in time and analyze any network, application, or security condition.

  4. 4. What Is Network Forensics? © WildPackets, Inc. www.wildpackets.com 4
  5. 5. What is Network Forensics ? • Marcus Ranum is credited with defining Network Forensics as “the capture, recording, and analysis of network events in order to discover the source of security attacks or other problem incidents.” (wikipedia) • It’s not like TV – employ forensics before the “crime” - network traffic is transmitted and then lost, leaving no clues behind • Other names: packet mining, packet forensics, digital forensics #wp_forensics Network Forensics for Wired and Wireless Networks © WildPackets, Inc.
  6. 6. What Purpose Does It Serve ? • Allows us to find the details of network events after they have happened • Eliminates the need to reproduce network problems • Distill data to manageable levels by employing filters and analysis #wp_forensics Network Forensics for Wired and Wireless Networks © WildPackets, Inc.
  7. 7. Network vs. Security Forensics • Network forensics is a superset of security forensics • Forensics is not just DPI (Deep Packet Inspection) • Requires the lossless capture, storage, and analysis of extremely large data volumes • Network forensics: enterprise vs. lawful intercept ‒ Concerned with the process of reconstructing a network event • Network or infrastructure outage • Intrusion such as a “hack” or other penetration ‒ Provides a recording of the actual incident • Based on live IP packet data captures ‒ A new way of looking at trace file analysis ‒ Continues from where traditional network troubleshooting ends #wp_forensics Network Forensics for Wired and Wireless Networks © WildPackets, Inc.
  8. 8. Network Forensics Drivers • Faster networks/greater data volumes ‒ 10/40G adoption grew 62% in 2012 ‒ 75% of the investments in networking are for 10G1 • Richer data • Subtler and more malicious security threats ‒ ‒ ‒ ‒ Zero-day attacks APTs (Advanced Persistent Threats) 75% of data breaches financially motivated 66% of breaches took months or longer to discover2 • Sampled data and high-level stats ‒ Flow-based network monitoring vs. detailed DPI analysis 1 http://www.infonetics.com/pr/2013/2H12-Networking-Ports-Market-Highlights.asp 2 http://www.verizonenterprise.com/resources/reports/rp_data-breach-investigations-report-2013_en_xg.pdf #wp_forensics Network Forensics for Wired and Wireless Networks © WildPackets, Inc. 8
  9. 9. Why Forensics? • Validate what your logs are telling you • Generate alarms/alerts on data you’ll never find in logs • Invest time analyzing, not reproducing • Immediately begin investigating the issue – you have a recording of the incident! • Isolate key data – from multi-TB archives - rapidly and intuitively • Understand the depth of penetration for any incident #wp_forensics Network Forensics for Wired and Wireless Networks © WildPackets, Inc.
