The spring up of cloud storage, such as Hadoop HDFS, Open Stack Swift, brings us more intelligent storage solutions. Nowadays, the most commercial version of cloud storage system puts more emphasis on high-performance and high-availability, very little attention is given to privacy protection. This paper proposes a user influence-based data distribution optimization method, User Rank, which migrate...
For the task scheduling problem in the heterogeneous grid environment, a security benefit function is constructed by considering the task scheduling demand for confidentiality, integrity and authenticity. Then, according to the history behavior of grid resource nodes, node's credibility dynamic evaluation method is proposed by using the weighted function. Based on these, a new grid task security scheduling...
This paper proposes a patch management model with non-homogeneous vulnerability-discovery processes to find the optimal security patch release times. The proposed model is an extension of Cavusoglu et al.\ (2006, 2008) by applying non-homogeneous vulnerability-discovery processes which are based on a vulnerability life-cycle model, and provides the optimal schedule for security patch release times...
In this paper, we discuss the product selection problem of the information security technology system under the conditions of existing cooperation between the security products. We introduce the conception of cooperative performance-price ratio of such products in the system and establish a corresponding mathematical model. For this problem, we designed a dependent arithmetic based on the genetic...
