D3.3 - An attack-tolerant framework for the cloud V1

This document presents an overview of monitoring and attack-tolerant techniques that will be used as a basis for the attack-tolerant framework to be integrated in the CLARUS platform, to early detect security and privacy incidents and to be able to react to them at runtime by applying a set of countermeasures in order to mitigate undesired effects.

This document offers an overview of monitoring and attack-tolerant systems in the cloud, and constitutes the basis of the attack-tolerant framework that will be integrated in CLARUS to enable the continuous monitoring of the system with the aim of preserving security and privacy properties. The innovation behind this attack-tolerant system comes from the fact that the system will be able to continue its operation in the event of an attack.
