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

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

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
