The Development of a graduate course on identity management for the Department of Networking, Security, and Systems Administration

Digital identities are being utilized more than ever as a means to authenticate computer users in order to control access to systems, web services, and networks. To maintain these digital identities, administrators turn to Identity Management solutions to offer protection for users, business partners, and networks. This paper proposes an analysis of Identity Management to be accomplished in the form of a graduate level course of study for a ten-week period for the Networking, Security, and Systems Administration department at Rochester Institute of Technology. This course will be designed for this department because of its emphasis on securing, protecting, and managing the identities of users within and across networks. Much of the security-related courses offered by the department focus primarily on security within enterprises. Therefore, Identity Management, a topic that is becoming more popular within enterprises each day, would compliment these courses. Students that enroll in this course will be more equipped to satisfy the needs of modern enterprises when they graduate because they will have a better understanding of how to address security issues that involve managing user identities across networks, systems, and enterprises. This course will focus on several aspects of Identity Management and its use in enterprises today. Covered during the course will be the frameworks of Identity Management, for instance, Liberty Identity Federation Framework and OASIS SAML 2.0; the Identity Management models; and some of the major Identity Management solutions that are in use today such as Liberty Alliance, Microsoft Passport, and Shibboleth. This course will also provide the opportunity to gain hands on experience by facilitating exemplar technologies used in laboratory investigations

A Survey of Access Control Models in Wireless Sensor Networks

Copyright 2014 by the authors; licensee MDPI, Basel, Switzerland. This article is an open access article distributed under the terms and conditions of the Creative Commons Attribution license (http://creativecommons.org/licenses/by/3.0/)Wireless sensor networks (WSNs) have attracted considerable interest in the research community, because of their wide range of applications. However, due to the distributed nature of WSNs and their deployment in remote areas, these networks are vulnerable to numerous security threats that can adversely affect their proper functioning. Resource constraints in sensor nodes mean that security mechanisms with a large overhead of computation and communication are impractical to use in WSNs; security in sensor networks is, therefore, a challenge. Access control is a critical security service that offers the appropriate access privileges to legitimate users and prevents illegitimate users from unauthorized access. However, access control has not received much attention in the context of WSNs. This paper provides an overview of security threats and attacks, outlines the security requirements and presents a state-of-the-art survey on access control models, including a comparison and evaluation based on their characteristics in WSNs. Potential challenging issues for access control schemes in WSNs are also discussed.Peer reviewe

Who wrote this scientific text?

The IEEE bibliographic database contains a number of proven duplications with indication of the original paper(s) copied. This corpus is used to test a method for the detection of hidden intertextuality (commonly named "plagiarism"). The intertextual distance, combined with the sliding window and with various classification techniques, identifies these duplications with a very low risk of error. These experiments also show that several factors blur the identity of the scientific author, including variable group authorship and the high levels of intertextuality accepted, and sometimes desired, in scientific papers on the same topic

Strategic Self-Presentation on Social Networking Sites

Contemporarily social networking sites utilize an idealized self-presentation to reach out to diverse and individual users. The information communicated across users has drifted to incorporate unanticipated gains of reforms focusing on empowering users to have total control of their account and profile information. Constructing a self-presentation in online social networking requires the collection of content, layout and design to reflect personality and goals. This study tends to present the relative impact of various self-presentation styles on improving the quality of services afforded by social networking sites. Findings based on the dominant self-presentation such as self-promotion, ingratiation, exemplification, supplication, and intimidation were expressed in terms of impression and behavior as well as their impeding risk. Findings on self-presentation on social networking sites confines to the pinning effect of socializing with other online users via online social networking sites such as Facebook. Keywords: Self-presentation, Facebook, Social networking, Networking community, Account information

A MORPHOLOGY OF THE ORGANISATION OF DATA GOVERNANCE

Both information systems (IS) researchers and practitioners consider data governance as a promising approach for companies to improve and maintain the quality of corporate data, which is seen as critical for being able to meet strategic business requirements, such as compliance or integrated customer management. Both sides agree that data governance primarily is a matter of organisation. However, hardly any scientific results have been produced so far indicating what actually has to be organised by data governance, and what data governance may look like. The paper aims at closing this gap by developing a morphology of data governance organisation on the basis of a comprehensive analysis of the state of the art both in science and in practice. Epistemologically, the morphology represents an analytic theory, as it serves for structuring the research topic of data governance, which is still quite unexplored. Six mini case studies are used to evaluate the morphology by means of empirical data. Providing a foundation for further research, the morphology contributes to the advancement of the scientific body of knowledge. At the same time, it is beneficial to practitioners, as companies may use it as a guideline when organising data governance

L'intertextualité dans les publications scientifiques

La base de données bibliographiques de l'IEEE contient un certain nombre de duplications avérées avec indication des originaux copiés. Ce corpus est utilisé pour tester une méthode d'attribution d'auteur. La combinaison de la distance intertextuelle avec la fenêtre glissante et diverses techniques de classification permet d'identifier ces duplications avec un risque d'erreur très faible. Cette expérience montre également que plusieurs facteurs brouillent l'identité de l'auteur scientifique, notamment des collectifs de chercheurs à géométrie variable et une forte dose d'intertextualité acceptée voire recherchée

Cryptographic Key Management in Delay Tolerant Networks (DTNs): A survey

Since their appearance at the dawn of the second millennium, Delay or Disruption Tolerant Networks (DTNs) have gradually evolved, spurring the development of a variety of methods and protocols for making them more secure and resilient. In this context, perhaps, the most challenging problem to deal with is that of cryptographic key management. To the best of our knowledge, the work at hand is the first to survey the relevant literature and classify the various so far proposed key management approaches in such a restricted and harsh environment. Towards this goal, we have grouped the surveyed key management methods into three major categories depending on whether the particular method copes with a) security initialization, b) key establishment, and c) key revocation. We have attempted to provide a concise but fairly complete evaluation of the proposed up-to-date methods in a generalized way with the aim of offering a central reference point for future research
