Peeking Through the Cloud: Client

Density Estimation via DNS Cache

Probing

  • What is DNS?
  • Why should we use Cloud Computing?
  • What is Cache Probing?
  • What is Botnet?

DNS

  • Domain name space consists tree of domain names.
  • The tree sub – divides into zones at the root zone.
  • The old zone ceases to authorities to the new zone.

Cloud Computing

  • Achieve economics of scale
  • Reduce spending on technology

infrastructure

  • Reduce capital costs
  • Improve flexibility
  • Improve accessibility

Experimental Evaluation

  • Centralized Scheduler for starting Iperf clients -Predefined serialized schedule file at each VM instance. -Schedule file contains a time stamp along with the nodes that should communicate for a single reading.
  • Iperf - Network testing tool to measure the network throughput between end hosts.

Web Metering

  • Website Metering - fastest and easiest way to see website ranks
  • No manual digging and guessing
  • Website Popularity is fully automated and runs right from your desktop
  • The strong correlation between website popularity, benefits and techniques for rank inflation

Botnet

  • Botnet is used to defined the user network by Bot master
  • Develop a scalable and robust infrastructure to capture & concurrently track multiple Botnets
  • IRC tracking, DNS Cache probing (minimal)
  • Must be benign – not used to infect others outside the testing environment
  • Analysis of measurements, structural and behavioral aspect of Botnets

Birth of Botnet

  • Bots are born from

program binaries that infect your PC

  • Self-replicating worms
  • E-mail viruses
  • Shell code (scripts)

Conclusion

  • In this paper, we provide a ne technique for Internet demographics, the client population density of service. Also verifying the popularity rank of a website and estimating of botnet infection. A refined techniques for estimating botnet size with improving their benefits.
