In Distributed Virtualized Environment, service components on a dependable service path will be selected to implement service composition. Searching for the optimal dependable service path is the key to implement dependability assurance, which is a Multi-Constrained Optimal Path problem. However, the existing algorithms have disadvantages of high complexity and low performance, and lacking the consideration...
The increasing complexity of modern distributed systems makes conventional fault tolerance and recovery prohibitively expensive. One of the promising approaches is online failure prediction. However, the process of feature extraction depends on the experienced administrators and their domain knowledge to filtering and compressing error events into a form that is easy for failure prediction. In this...
Network security situational awareness(NSSA) has been a hot research spot in the network security domain. In this paper, a quantification method for NSSA based on conditional random fields(CRFs) was proposed. The data of network attacks from intrusion detection system (IDS), the hosts' vulnerabilities and the hosts' states were firstly combined as the network security factors. And then the network...
