Abstract:

Software systems have become complex in the last few decades. The complexity leads to bugs, misconfigurations, and vulnerabilities, which can be exploited to leak sensitive data, commit frauds, or even affect social or political discourse. I work on building systems that mitigate various threats to data privacy in online services. In this talk, I will describe one class of threats -- the network side channels, which can leak sensitive data through traffic shape, i.e., packet sizes and timing. I will then describe Pacer, a cloaked tunnel abstraction and a system based on this abstraction to mitigate network side-channel leaks in infrastructure-as-a-service Cloud tenants
