Context. With the development of computer software, hardware, and communication technologies, a new type of human-centered computing model, called Cloud Computing (CC) has been established as a commercial computer network service. However, the openness of CC brings huge security challenge to the identity-based access control system, as it not able to effectively prevent malicious users accessing; information security problems, system stability problems, and also the trust issues between cloud service users (CSUs) and cloud service providers (CSPs) are arising therefrom.

Streszczenie:

Mechanisms must be provided to protect resources from attackers when users request access to resources in network environments. Role-Based Access Control (RBAC) formulates that access decisions are based on the roles that individual users have as members of a system. In RBAC, there are role hierarchies in which a senior role inherits the permissions of a junior role. In order to allow a junior role to perform one or more tasks of a senior role, various delegation models have been proposed in the literature, including Role-Based Access Control Model (RBAC96), Role-Based Delegation Model (RBDM0)

Whitelisting IP addresses and hostnames allow organizations to employ a default-deny approach to network traffic. Organizations employing a default-deny approach can stop many malicious threats, even including zero-day attacks, because it only allows explicitly stated legitimate activities. However, creating a comprehensive whitelist for a default-deny approach is difficult due to user-supplied destinations that can only be known at the time of usage. Whitelists, therefore, interfere with user experience by denying network traffic to user-supplied legitimate destinations. In this thesis, we fo

Today, one is expected to remember multiple user names and passwords for different domains when one wants to access on the Internet.

This has raised concerns about how the users’ contents are protected and how the privacy of users is preserved by the service providers.

This thesis evaluates the use of a loadtime metaobject protocol as a practical mechanism for enforcing access control policies upon applications distributed as user-level compiled code. Enforcing access control policies upon user-level compiled code is necessary because there are many situations where users are vulnerable to security breaches because they download and run potentially untrustworthy applications provided in the form of user-level compiled code. These applications might be distributed applications so access control for both local and distributed resources is required. Examples of

In this study, the effect of computer use and Logo instruction on students' perceived control of computers and generalized perceived control was examined. Third and fourth grade students (<u>N</u>=90) in four intact groups, consisting of one treatment and one control group for each grade level, were pre- and posttested, using the computer control survey (CCS) and the Chi1dren's Nowicki-Strickland Locus of Control Scale (CNS-IE). A posttest measure of Logo achievement was obtained from the treatment students. Three way analyses of covariance, using the pretest scores as the covariate, were use

It is widely accepted that low energy consumption is the most important requirement when designing components and systems for a wireless sensor network (WSN). The greatest energy consumer of each node within a WSN is the radio transceiver and as such, it is important that this component be used in an extremely energy e±cient manner. One method of reducing the amount of energy consumed by the radio transceiver is to turn it off and allow nodes to enter a sleep mode. The algorithms that directly control the radio transceiver are traditionally grouped into the Medium Access Control

This thesis examines how global environmental crisis narratives and discourses have influenced environmental policy and practice in conservation programmes for the Okavango Delta, Botswana. In particular, it highlights the contested nature of biodiversity conservation and the embedded power relations in the framing, definition and crafting of solutions to the problem of biodiversity degradation at local, national and international levels. The thesis therefore examines, based on these framings, the consequences of global environmental agreements, such as the Ramsar Convention and the UN Convent

[EN] Nowadays, online social networks (OSNs) have become a mainstream cultural phenomenon for millions of Internet users. Social networks are an ideal environment for generating all kinds of social benefits for users. Users share experiences, keep in touch with their family, friends and acquaintances, and earn economic benefits from the power of their influence (which is translated into new job opportunities). However, the use of social networks and the action of sharing information imply the loss of the users’ privacy. Recently, a great interest in protecting the privacy of users has em

Streszczenie:

Energy efficiency contributes to the survival of nodes in Mobile Ad Hoc Networks (MANETs). The use of directional antennas can conserve energy due to the increased gain and directed transmission towards specific point in space. Directional antennas also resolve many issues associated with interference from different points within the network. Despite the vast body of work in this area, research on the way directional antennas access the wireless medium specific to Ultra-WideBand (UWB) systems have not gained wide attention. The aim of this research is to design, implement and test an improved

Les robots à tubes concentriques deviennent de plus en plus populaires dans la communauté de la robotique médicale. Dans cette thèse, un état de l’art général des travaux existants et qui couvre les thématiques de recherche en robots à tubes concentriques (RTC) est présenté dans un premier temps. Les modélisations géométrique (directe et inverse) et cinématique des RTC sont détaillées car elles servent de base pour les contributions de cette thèse. La première contribution consiste en une étude de concept d’utilisation des RTCs pour la résection des tumeurs profondes situées au niveau du lobe

Il lavoro è stato suddiviso in tre macro-aree. Una prima riguardante un'analisi teorica di come funzionano le intrusioni, di quali software vengono utilizzati per compierle, e di come proteggersi (usando i dispositivi che in termine generico si possono riconoscere come i firewall). Una seconda macro-area che analizza un'intrusione avvenuta dall'esterno verso dei server sensibili di una rete LAN. Questa analisi viene condotta sui file catturati dalle due interfacce di rete configurate in modalità promiscua su una sonda presente nella LAN. Le interfacce sono due per potersi interfacciar

The servers use the user’s identifier and password for user authentication, and achieve the purpose of access control. The computer system environment of single machine operation is simple and easy to maintain, and its user has complete access right of all files. As the network is quick growth, some computer systems do not operate by alone, and they are linked to be a distributed computer system, in which the users can access the data by a remote co
