Telco Cloud Resilience: Synergies between Fault and Security Management

This work capitalizes on the concept of network function virtualization at the telco cloud, and presents a joint study between fault management and security management. Specifically, the commonalities of fault and security management are put forward, along with a resource allocation study in common slice deployments. In this regard, a security threat analysis is presented, which sheds light onto the impact of security threats on network fault management. The interdependence between security and fault management is highlighted via three use cases, where distinct levels of resource trade-offs are identified. Along with such use cases, the paper provides also an overview of the resulting resource allocation process, where the requirements of the corresponding slice are analyzed towards an overall efficient resource usage.
