Web Single Sign-On Authentication using SAML
Companies have increasingly turned to application service providers (ASPs) or Software as a Service (SaaS) vendors to offer specialized web-based services that will cut costs and provide specific and focused applications to users. The complexity of designing, installing, configuring, deploying, and supporting the system with internal resources can be eliminated with this type of methodology, providing great benefit to organizations. However, these models can present an authentication problem for corporations with a large number of external service providers. This paper describes the implementation of Security Assertion Markup Language (SAML) and its capabilities to provide secure single sign-on (SSO) solutions for externally hosted applications
A JSON Token-Based Authentication and Access Management Schema for Cloud SaaS Applications
Cloud computing is significantly reshaping the computing industry built
around core concepts such as virtualization, processing power, connectivity and
elasticity to store and share IT resources via a broad network. It has emerged
as the key technology that unleashes the potency of Big Data, Internet of
Things, Mobile and Web Applications, and other related technologies, but it
also comes with its challenges - such as governance, security, and privacy.
This paper is focused on the security and privacy challenges of cloud computing
with specific reference to user authentication and access management for cloud
SaaS applications. The suggested model uses a framework that harnesses the
stateless and secure nature of JWT for client authentication and session
management. Furthermore, authorized access to protected cloud SaaS resources
have been efficiently managed. Accordingly, a Policy Match Gate (PMG) component
and a Policy Activity Monitor (PAM) component have been introduced. In
addition, other subcomponents such as a Policy Validation Unit (PVU) and a
Policy Proxy DB (PPDB) have also been established for optimized service
delivery. A theoretical analysis of the proposed model portrays a system that
is secure, lightweight and highly scalable for improved cloud resource security
and management.Comment: 6 Page
Implementing Azure Active Directory Integration with an Existing Cloud Service
Training Simulator (TraSim) is an online, web-based platform for holding crisis management exercises. It simulates epidemics and other exceptional situations to test the functionality of an organization’s operating instructions in the hour of need. The main objective of this thesis is to further develop the service by delegating its existing authentication and user provisioning mechanisms to a centralized, cloud-based Identity and Access Management (IAM) service. Making use of a centralized access control service is widely known as a Single Sign-On (SSO) implementation which comes with multiple benefits such as increased security, reduced administrative overhead and improved user experience.
The objective originates from a customer organization’s request to enable SSO for TraSim. The research mainly focuses on implementing SSO by integrating TraSim with Azure Active Directory (AD) from a wide range of IAM services since it is considered as an industry standard and already utilized by the customer. Anyhow, the complexity of the integration is kept as reduced as possible to retain compatibility with other services besides Azure AD. While the integration is a unique operation with an endless amount of software stacks that a service can build on and multiple IAM services to choose from, this thesis aims to provide a general guideline of how to approach a resembling assignment.
Conducting the study required extensive search and evaluation of the available literature about terms such as IAM, client-server communication, SSO, cloud services and AD. The literature review is combined with an introduction to the basic technologies that TraSim is built with to justify the choice of OpenID Connect as the authentication protocol and why it was implemented using the mozilla-django-oidc library. The literature consists of multiple online articles, publications and the official documentation of the utilized technologies. The research uses a constructive approach as it focuses into developing and testing a new feature that is merged into the source code of an already existing piece of software

Patient privacy protection using anonymous access control techniques
Objective: The objective of this study is to develop a solution to preserve security and privacy in a healthcare environment where health-sensitive information will be accessed by many parties and stored in various distributed databases. The solution should maintain anonymous medical records and it should be able to link anonymous medical information in distributed databases into a single patient medical record with the patient identity. Methods: In this paper we present a protocol that can be used to authenticate and authorize patients to healthcare services without providing the patient identification. Healthcare service can identify the patient using separate temporary identities in each identification session and medical records are linked to these temporary identities. Temporary identities can be used to enable record linkage and reverse track real patient identity in critical medical situations. Results: The proposed protocol provides main security and privacy services such as user anonymity, message privacy, message confidentiality, user authentication, user authorization and message replay attacks. The medical environment validates the patient at the healthcare service as a real and registered patient for the medical services. Using the proposed protocol, the patient anonymous medical records at different healthcare services can be linked into one single report and it is possible to securely reverse track anonymous patient into the real identity. Conclusion: The protocol protects the patient privacy with a secure anonymous authentication to healthcare services and medical record registries according to the European and the UK legislations, where the patient real identity is not disclosed with the distributed patient medical records
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
Choice of suitable Identity and Access Management standards for mobile computing and communication
© 2017 IEEE. Enterprises have recognised the importance of personal mobile devices for business and official use. Employees and consumers have been freely accessing resources and services from their principal organisation and partners' businesses on their mobile devices, to improve the efficiency and productivity of their businesses. This mobile computing-based business model has one major challenge, that of ascertaining and linking users' identities and access rights across business partners. The parent organisation owns all the confidential information about users but the collaborative organisation has to verify users' identities and access rights to allow access to their services and resources. This challenge involves resolving how to communicate users' identities to collaborative organisations without sending their confidential information. Several generic Identity and Access Management (IAM) standards have been proposed, and three have become established standards: Security Assertion Markup Language (SAML), Open Authentication (OAuth), and OpenID Connect (OIDC). Mobile computing and communication have some specific requirements and limitations; therefore, this paper evaluates these IAM standards to ascertain suitable IAM to protect mobile computing and communication. This evaluation is based on the three types of analyses: Comparative analysis, suitability analysis and security vulnerability analysis of SAML, OAuth and OIDC
