Abstract: Cloud infrastructures play an increasingly important role for telecom operators, because they enable internal consolidation of resources with the corresponding savings in hardware and management costs. However, this same consolidation exposes core services of the infrastructure to very disruptive attacks. This is the case of monitoring, which needs to be dependable and secure to ensure proper operation of large datacenters and cloud infrastructures. We argue that currently existing centralized monitoring approaches (e.g., relying on a single solution provider, using single point of failure components) represent a huge risk, because a single vulnerability may compromise the entire monitoring infrastructure. In this paper, we describe the TRONE approach to trustworthy monitoring, which relies on multiple components to achieve increased levels of reliance on the monitoring data and hence increased trustworthiness. In particular, we focus on the TRONE framework for event dissemination, on security-oriented diagnosis based on collected events and on fast network adaptation in critical situations based on multi-homing application support. To validate our work, we will deploy and demonstrate our solutions in a live environment provided by Portugal Telecom.
