SOA have been deployed as a mean to offer a better flexibility, to increase efficiency through reuse of services and also to improve interoperability by providing new opportunities to connect heterogeneous platforms. However, those benefits make security more difficult to control. Fortunately, new standards are proposed to treat this issue, but their current use makes the architecture much more complex...
The 3 most important issues for anomaly detection based intrusion detection systems by using data mining methods are: feature selection, data value normalization, and the choice of data mining algorithms. In this paper, we study primarily the feature selection of network traffic and its impact on the detection rates. We use KDD CUP 1999 dataset as the sample for the study. We group the features of...
Compliance management (CM) is the management process that an organization implements to ensure organizational compliance with relevant requirements and expectations. Compliance auditing (CA) is a child-process of CM where compliance rules and policies are individually checked against the organization to determine the level of compliance achieved by the organization. In this paper, we arrange organizational...
Collecting data on user activities is one of the fundamental middleware services in Web-enabled systems. The collected data is analyzed and used by various high-level services, like user profiling, accounting, security auditing, and system health monitoring. In this paper, we present architecture and performance evaluation of usage tracking components for service-oriented middleware systems. Presented...
We developed a quality of service (QoS) management system to support service level management (SLM) for global enterprise services. The QoS management system is integrated with one of our enterprise services in a preproduction system, an identical system as the production system but in a test environment. Lab experiments showed that our integrated solution helps global enterprise services to better...
Information privacy typically concerns the confidentiality of personal identifiable information (PII) and protected health information (PHI) such as electronic medical records. Thus, the information access control mechanism for e-health services must be embedded with privacy-enhancing technologies. Role-based access control (RBAC) model has been widely investigated and applied to various applications...
