    Architecture for Provenance Systems

    No full text
    This document covers the logical and process architectures of provenance systems. The logical architecture identifies key roles and their interactions, whereas the process architecture discusses distribution and security. A fundamental aspect of our presentation is its technology-independent nature, which makes it reusable: the principles that are exposed in this document may be applied to different technologies

    Provenance Threat Modeling

    Provenance systems are used to capture history metadata, applications include ownership attribution and determining the quality of a particular data set. Provenance systems are also used for debugging, process improvement, understanding data proof of ownership, certification of validity, etc. The provenance of data includes information about the processes and source data that leads to the current representation. In this paper we study the security risks provenance systems might be exposed to and recommend security solutions to better protect the provenance information.Comment: 4 pages, 1 figure, conferenc

    In this paper we developed security architecture for the higher learning institutions in Tanzania which considers security measures to be taken at different level of the higher learning institutions’ data warehouse architecture. The primary objectives of the study was to identify security requirements of the higher learning institutions data warehouses and then study the existing security systems in and finally develop and architecture based on the requirements extracted from the study. The study was carried at three different universities in Tanzania by carrying out interviews, study of the existing systems in respective institutions and a literature review of the existing data warehouses systems and architectures. The result was the security requirements identified which lead to the development of the security architecture comprising security in source systems, data, and services to be offered by the DW, applications which use DW, networks and other physical infrastructure focusing on security controls like authentication, role-based access control, role separation of privileged users, storage of data, secure transfer of data, protective monitoring/ intrusion detection, penetration testing, trusted/secure endpoints and physical protection. Keywords: Data warehouse, security architecture, higher learning institution

    The Internet of Things (IoT) concept is evolving rapidly and influencing newdevelopments in various application domains, such as the Internet of MobileThings (IoMT), Autonomous Internet of Things (A-IoT), Autonomous Systemof Things (ASoT), Internet of Autonomous Things (IoAT), Internetof Things Clouds (IoT-C) and the Internet of Robotic Things (IoRT) etc.that are progressing/advancing by using IoT technology. The IoT influencerepresents new development and deployment challenges in different areassuch as seamless platform integration, context based cognitive network integration,new mobile sensor/actuator network paradigms, things identification(addressing, naming in IoT) and dynamic things discoverability and manyothers. The IoRT represents new convergence challenges and their need to be addressed, in one side the programmability and the communication ofmultiple heterogeneous mobile/autonomous/robotic things for cooperating,their coordination, configuration, exchange of information, security, safetyand protection. Developments in IoT heterogeneous parallel processing/communication and dynamic systems based on parallelism and concurrencyrequire new ideas for integrating the intelligent “devices”, collaborativerobots (COBOTS), into IoT applications. Dynamic maintainability, selfhealing,self-repair of resources, changing resource state, (re-) configurationand context based IoT systems for service implementation and integrationwith IoT network service composition are of paramount importance whennew “cognitive devices” are becoming active participants in IoT applications.This chapter aims to be an overview of the IoRT concept, technologies,architectures and applications and to provide a comprehensive coverage offuture challenges, developments and applications

    Evolving a secure grid-enabled, distributed data warehouse : a standards-based perspective

    As digital data-collection has increased in scale and number, it becomes an important type of resource serving a wide community of researchers. Cross-institutional data-sharing and collaboration introduce a suitable approach to facilitate those research institutions that are suffering the lack of data and related IT infrastructures. Grid computing has become a widely adopted approach to enable cross-institutional resource-sharing and collaboration. It integrates a distributed and heterogeneous collection of locally managed users and resources. This project proposes a distributed data warehouse system, which uses Grid technology to enable data-access and integration, and collaborative operations across multi-distributed institutions in the context of HV/AIDS research. This study is based on wider research into OGSA-based Grid services architecture, comprising a data-analysis system which utilizes a data warehouse, data marts, and near-line operational database that are hosted by distributed institutions. Within this framework, specific patterns for collaboration, interoperability, resource virtualization and security are included. The heterogeneous and dynamic nature of the Grid environment introduces a number of security challenges. This study also concerns a set of particular security aspects, including PKI-based authentication, single sign-on, dynamic delegation, and attribute-based authorization. These mechanisms, as supported by the Globus Toolkit’s Grid Security Infrastructure, are used to enable interoperability and establish trust relationship between various security mechanisms and policies within different institutions; manage credentials; and ensure secure interactions

    Overview and Features of Generic Security Protocols for Cloud Computing Environment

    Full text link
    - In this research paper we are describing the several generic protocols use in Cloud computing environment. Now-a-days Cloud Computing has become very important in large and small enterprise so security has also become very important for Cloud Computing. Several technique use to protect the cloud. Techniques are implemented by protocols. This paper is based on overview of protocols that use in Cloud computing environment. The protocols of cloud computing can also use in different security system such as Cryptonet System, Mailing System and Authentication System
