Security and Privacy Challenges in Cloud Computing Environments
TL;DR: This article explores the roadblocks and solutions to providing a trustworthy cloud computing environment and suggests a number of approaches that could be considered.
Journal ArticleDOI
A Survey of Defense Mechanisms Against Distributed Denial of Service (DDoS) Flooding Attacks
TL;DR: The primary intention for this work is to stimulate the research community into developing creative, effective, efficient, and comprehensive prevention, detection, and response mechanisms that address the DDoS flooding problem before, during and after an actual attack.
Journal ArticleDOI
A generalized temporal role-based access control model
TL;DR: This work proposes a generalized temporal role-based access control (GTRBAC) model capable of expressing a wider range of temporal constraints and allows expressing periodic as well as duration constraints on roles, user-role assignments, and role-permission assignments.
Journal ArticleDOI
Security models for web-based applications
TL;DR: Using traditional and emerging access control approaches to develop secure applications for the Web with a focus on mobile devices.
Journal ArticleDOI
Digital government security infrastructure design challenges
TL;DR: An approach that provides a theoretical foundation for the use of object-oriented databases and object-relational databases in data warehouse, multidimensional database, and online analytical processing applications and introduces a set of minimal constraints and extensions to the Unified Modeling Language for representing multiddimensional modeling properties for these applications.
