Blind Communication
  • What if you wanted to send a message to a system,
    but did not want anyone to see it.
  • Multi-owner systems,
  • Distributed collaboration tools,
  • Cloud computing,

Internet
  • Web of interconnected networks
  • Grows with no central authority
  • Autonomous Systems optimize local communication
    efficiency
  • The building blocks are engineered and studied in
    depth
  • Global entity has not been characterized

7
Internet Measurements
  • Need for Internet measurements arises due to
    commercial, social, and technical issues
  • Realistic simulation environment for developed
    products,
  • Improve network management
  • Robustness with respect to failures/attacks
  • Comprehend spreading of worms/viruses
  • Know social trends in Internet use
  • Scientific discovery
  • Scale-free (power-law), Small-world, Rich-club,
    Dissasortativity,

Traffic Measurements
  • Monitoring and measuring network traffic
  • to produce better models of network behavior
  • to diagnose failures and detect anomalies
  • to defend against unwanted traffic
  • PlanetLab

Code-Red Worm
  • On July 19, 2001, more than 359,000 computers
    connected to the Internet were infected with the
    Code-Red (CRv2) worm in less than 14 hours
  • Spread

15
Sapphire Worm
  • was the fastest computer worm in history
  • doubled in size every 8.5 seconds
  • infected more than 90 percent of vulnerable hosts
    within 10 minutes.

16
Witty Worm
  • reached its peak activity after approximately 45
    minutes
  • at which point the majority of vulnerable hosts
    had been infected
  • World
  • USA

17
Nyxem Email Virus
  • Estimate of total number of infected computers is
    between 470K and 945K
  • At least 45K of the infected computers were also
    compromised by other forms of spyware or botware
  • Spread

18
Scam Hosting
  • Study dynamics of scam hosting infrastructure

19
Internet Measurements
  • The Internet is man-made, so why do we need to
    measure it?
  • Because we still dont really understand it
  • Sometimes things go wrong
  • Malicious users
  • Measurement for network operations
  • Detecting and diagnosing problems
  • What-if analysis of future changes
  • Measurement for scientific discovery
  • Creating accurate models that represent reality
  • Identifying new features and phenomena
