Policy configuration and management in attribute based access control
No full textThe flexibility, scalability, dynamic nature, portability and identity-less features of Attribute Based Access Control (ABAC) make it an attractive choice to be employed as a means to enforce access control in many application domains.However, in order to realize the true benefit of ABAC, it is necessary to develop mechanisms to effectively configure, deploy, maintain, and manage it. Towards this end, this dissertation makes the following four contributions. First, we develop two ABAC policy mining algorithms that utilize existing permissions of users on the resources as well as the attribute information for both users and resources to automatically discover ABAC policies. Next, we develop an approach that can incrementally maintain ABAC policies by appropriately modifying the policy based on updates in permission and/or user/object attributes. Since commercially viable systems for implementation of ABAC are not widely available, we next address the deployment of ABAC on legacy systems. Specifically, we develop a low-cost approach for the translation of an ABAC policy into a form that can be adopted by an RBAC system. Our fourth and final contribution addresses policy reconciliation and migration in collaborative environments. Specifically, we propose the notion of policy equivalence in ABAC and develop methods to evaluate ABAC policy similarity. We also propose two different approaches for accomplishing policy reconciliation and an approach for policy migration. Together, this work helps organization to migrate to ABAC from the traditional discretionary access control (DAC), to efficiently maintain it in light of situational changes, and to deploy it in legacy systems and enable effective collaboration across organizations while respecting their individual security policies.Ph.D.Includes bibliographical reference
Spiritual Idealism in the Works of Emerson: An Indian Approach
Get PDFRalph Waldo Emerson, an American author, endeavoured to establish new dimension of ideology by balancing the scientific materialism and conventional interpretation and beliefs in religious realm. In fact, his literary creation reveals his faith and inclination towards the ideology of spirit rather than to peep into the religious orthodoxy. He along with William James motivated New Thought Churches in America and dedicated himself in enhancing and extending the effect of the spiritual movements of the 1950’s and 60’s. He continued to illustrate the depth of spirituality through his speeches, poems and essays. For him, there is an occult relation between man and the universe around him and in the wide expanse of nature, he could feel a liberation from the tyranny of things. A minute analysis of his works clarifies his penchant to stimulate the new generation to know about their own entity as well as, the adjacency of ultimate truth, and the realization of supremacy in natural phenomena. The present paper aims to present the compendious conceptions of Emerson about spirituality intermingled with idealism through the microscopic lens of Indian philosophy. This approach will highlight the need to have enough acumen and intrinsic potential to discover a new intellectual path in the realm of spiritual idealistic studies
