This document summarizes a presentation about defending workloads from zero-day vulnerabilities. It discusses the traditional responsibility model where the customer is responsible for security up to the operating system layer. It then introduces AWS' shared responsibility model where AWS is responsible for security of the cloud infrastructure and the customer is responsible for security in the operating system and above. The presentation covers responding to the Shellshock bash vulnerability by reviewing network and security configurations, applying intrusion prevention, creating a new AMI with the patch, and implementing integrity monitoring. It emphasizes automating response workflows and instantiating from hardened AMIs to rapidly repair systems upon discovery of new vulnerabilities.
