Measuring and Mitigating the Risk of IP Reuse on Public Clouds

Explore the risks and vulnerabilities associated with IP reuse on public cloud platforms in this 21-minute IEEE conference talk. Delve into the concept of cloud squatting, learn about measuring IP reuse through bottom-up approaches, and understand the types of latent configurations that can lead to security issues. Examine the characterization of cloud IP reuse, vulnerable cloud services, and exploitable third-party services. Discover the implications for domain names and learn about the disclosures made to cloud providers. Gain insights into potential defenses, mitigations, and actions taken by Amazon to address these concerns.
