A peek under the Blue Coat presented at Syscan 2015

by Raphaël Rigo,

Summary : Blue Coat ProxySG systems are widely deployed in big corporations to handle web traffic proxying and filtering.
While they are very common, no work has ever been published regarding the internals of the system.
With this talk, I intend to present the results of a detailed analysis of the entirely proprietary SG OS, which runs on commodity Intel hardware.
The talk will include a detailed description of :
- OS mechanisms
- file system internals
- security mechanisms (or lack thereof).
