    Revealing the unseen: how to expose cloud usage while protecting user privacy

    Full text link
    Cloud users have little visibility into the performance characteristics and utilization of the physical machines underpinning the virtualized cloud resources they use. This uncertainty forces users and researchers to reverse engineer the inner workings of cloud systems in order to understand and optimize the conditions their applications operate. At Massachusetts Open Cloud (MOC), as a public cloud operator, we'd like to expose the utilization of our physical infrastructure to stop this wasteful effort. Mindful that such exposure can be used maliciously for gaining insight into other user's workloads, in this position paper we argue for the need for an approach that balances openness of the cloud overall with privacy for each tenant inside of it. We believe that this approach can be instantiated via a novel combination of several security and privacy technologies. We discuss the potential benefits, implications of transparency for cloud systems and users, and technical challenges/possibilities.Accepted manuscrip

    Ngā mahi: Kaupapa Māori outcomes and indicators kete

    As part of the Planning Under Cooperative Mandates research (PUCM) we developed a kaupapa Māori outcomes and indicators framework. This framework reflects tikanga Māori and Māori values. It also considers issues (including environmental issues) according to those tikanga that particular issues invoke. For example, tikanga brought into play in relation to council treatment and disposal of sewerage include tapu (sacred), and might also impact on the mauri (life-force) of water if treated effluent were to enter waterways. The intention of our research has been to clarify and define key Māori environmental concepts so that stakeholders (including council staff) will have a terms of reference against which they can compare desired environmental outcomes from different perspectives and be better placed to integrate Māori environmental outcomes into planning processes. The end-point is this Nga Mahi kete report containing tikanga-based worksheets and the guidelines for using them

    Māori provisions in plans: Mana whenua, mauri of water, and wahi tapu

    The intention of this document is to allow those using Ngā Mahi: Kaupapa Māori Outcomes an Indicators Kete (Jefferies and Kennedy, 2009, PUCM Māori Report 2) to view a range of examples of Māori provisions within statutory planning documents against plans being evaluated. The extracts in this Report 3 on Māori Provisions in Plans relate to the three tikanga in the Ngā Mahi report: Mana Whenua, Mauri (relating to water), and Wähi Tapu. It is intended that as we develop new kete (containing worksheets and user guides) and thereby expand Ngā Mahi, this current report will be revised to include plan provisions relating to additional tikanga

    PROTECT: container process isolation using system call interception

    Get PDF
    Virtualization is the underpinning technology enabling cloud computing service provisioning, and container-based virtualization provides an efficient sharing of the underlying host kernel libraries amongst multiple guests. While there has been research on protecting the host against compromise by malicious guests, research on protecting the guests against a compromised host is limited. In this paper, we present an access control solution which prevents the host from gaining access into the guest containers and their data. Using system call interception together with the built-in AppArmor mandatory access control (MAC) approach the solution protects guest containers from a malicious host attempting to compromise the integrity of data stored therein. Evaluation of results have shown that it can effectively prevent hostile access from host to guest containers while ensuring minimal performance overhead

    Environmental performance outcomes and indicators for indigenous peoples: Review of literature

    Get PDF
    The literature review in this report was the starting point for developing a Māori research strand (2003-2009) within the Planning Under Co-operative Mandates (PUCM) research programme (1995-2009). An early task of the PUCM Māori team was to review the international literature on environmental outcomes and indicators for indigenous peoples. This was in order to gain an understanding of what had been written on the subject and to become familiar with approaches taken by others that might provide lessons for the development of our proposed kaupapa Māori outcomes and indicators framework and methodology, which was aimed at local government performance in Aotearoa/New Zealand. This current report is not intended to provide an exhaustive catalogue of writings on environmental performance outcomes and indicators for indigenous peoples, including Māori. Rather, some of the more obvious and important writings are noted as a ready reference for others interested in this topic. Before detailing the approach we took in carrying out the review, the key terms, outcomes and indicators, are defined

    Autonomic computing meets SCADA security

    Get PDF
    © 2017 IEEE. National assets such as transportation networks, large manufacturing, business and health facilities, power generation, and distribution networks are critical infrastructures. The cyber threats to these infrastructures have increasingly become more sophisticated, extensive and numerous. Cyber security conventional measures have proved useful in the past but increasing sophistication of attacks dictates the need for newer measures. The autonomic computing paradigm mimics the autonomic nervous system and is promising to meet the latest challenges in the cyber threat landscape. This paper provides a brief review of autonomic computing applications for SCADA systems and proposes architecture for cyber security

    Resource management, plan quality and governance: A report to Government

    Get PDF
    This Report contains the main findings from FRST-funded research into planning under the Resource Management Act. It includes five sets of interrelated recommendations. These recommendations identify many actions that are essential if Government is serious about achieving its goal of environmental sustainability. Implementation of the recommendations will require a significant increase in expenditure at all levels of the planning hierarchy, but especially central government
