Visualizing Real-Time Network Resource Usage

DESCRIPTION

This paper presents NetGrok, a visualization tool designed for real-time monitoring of network resource usage. Developed by students at the University of Maryland, this tool addresses the challenges network administrators face with traditional text-based data analysis methods. With features like hashed layouts for consistent node placement and interactive filtering, NetGrok simplifies the visualization of complex network behaviors, enabling admins to detect attacks and topology changes more efficiently. The tool is built using Java and the Prefuse toolkit and aims to enhance the security and usability of network monitoring.

Presentation Transcript

  1. Visualizing Real-Time Network Resource Usage Ryan Blue, Cody Dunne, Adam Fuchs, Kyle King, and Aaron Schulman University of Maryland, Dept. of Computer Science Contact: cdunne@cs.umd.edu Workshop on Visualization for Computer Security September 15, 2008 Boston, MA

  2. Introduction • Computer network data is rich, and full of interesting patterns • Adversarial behavior • Configuration problems • Unfair resource usage • Network administrators don’t typically use visualization tools • Too much data to see visually • Cluttered • Hard to follow • Primary tools are text based • NetGrok brings new visualizations to network administrators

  3. Goals • Real-time • Visual stability • Identify local systems • Monitor behavior • Attacks • Topology changes • Unusual network usage

  5. Contributions • Hashed layout for consistent node placement • Grouped, home-centric network layout • Treemap showing connections between nodes without occlusion • Mouse-over and preferential display of edges reduces visual complexity • Application of filter and selection widgets to network visualization • Visualization framework for real-time IP data flows

  6. Implementation Details • Built in Java • Visualizations and data store built primarily using the Prefuse toolkit, • Custom data structures and visualizations • Packet capturing and PCAP file reading use the JPCAP library • GUI constructed with Jigloo Eclipse plugin

  7. Professional Feedback • Expert user: Brad Plecs, Network Administrator for the CS Dept. at UMD • Use case meetings (2 x 1 hr + emails) • PCAP and live capture analysis (1 hr) • Likert scale questionnaire • Positive: • Filter sliders, esp. time histogram • Intuitive layout and grouping • "NetGrok is excellent as a real-time diagnostic" • Criticisms: • Needs to be aware of transport layer data (TCP/UDP) • Dynamic grouping • Animations are confusing, distracting, and slow • Treemaps interesting but not intuitive

  8. Future Work • Add support for aging off old data • Add more visualizations • Semantic substrates for foreign host layout • Coarser views for larger data sets • Personal security tool

  9. Acknowledgments • Professor Ben Shneiderman our advisor • Brad Plecs for offering expert advice and participation in our preliminary case study • Thomas Lotze, Joonghoon Lee, Michael VanDaniker, Fatemeh Mir Rashed, Abigail Daken, Michael Lam, Huimin Guo, and Krist Wongsuphasawat our class paper reviewers
