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.
