Systematic Literature Review on the LDAP Protocol As a Centralized Mechanism for the Authentication of Users in Multiple Systems

The protocol LDAP (Lightweight Directory Access Protocol) allows centralized identity authentication, where the information of the directory is faster and easier to read. This article carries out a systematic literature review (SLR) according to what is proposed in the article by Bárbara Kitchenham [1], aimed to identify different methods for users’ authentication in multiple systems using LDAP protocol, an analysis of criteria is carried out about different studies published in five digital libraries (Scopus, IEEEXplorer, Scientific.net, Google Scholar, DBLP), and two academic magazines (Revista Energía of UNL, Revista Científica of UTB), making relevant conclusions of the use of four mechanisms for the authentication of users of multiple systems such as: Languaje PHP, SSO (Single sign-on), IAM (Identity and Access Management), and T-RBAC (Access control based on roles and tasks), predominantly the use of the PHP language for its administrative tools for managing LDAP servers.     Keywords: LDAP, authentication, user management, systematic literature review, securit

The PERMIS X.509 Based Privilege Management Infrastructure

This document describes the PERMIS X.509 Based Privilege Management Infrastructure, which is a trust management system as described in RFC 2704 [2]. The PERMIS Infrastructure is compared with the AAA Authorisation Framework described in RFC 2904 [4], and is shown to be compatible with it

Internet X.509 Public Key Infrastructure Operational Protocols -- LDAPv3

This document describes the features of the Lightweight Directory Access Protocol v3 that are needed in order to support a public key infrastructure based on X.509 certificates and CRLs

Identity and Access Management System: a Web-Based Approach for an Enterprise

Managing digital identities and access control for enterprise users and applications remains one of the greatest challenges facing computing today. An attempt to address this issue led to the proposed security paradigm called Identity and Access Management (IAM) service based on IAM standards. Current approaches such as Lightweight Directory Access Protocol (LDAP), Central Authentication Service (CAS) and Security Assertion Markup Language (SAML) lack comprehensive analysis from conception to physical implementation to incorporate these solutions thereby resulting in impractical and fractured solutions. In this paper, we have implemented Identity and Access Management System (IAMSys) using the Lightweight Directory Access Protocol (LDAP) which focuses on authentication, authorization, administration of identities and audit reporting. Its primary concern is verification of the identity of the entity and granting correct level of access for resources which are protected in either the cloud environment or on-premise systems. A phased approach methodology was used in the research where it requires any enterprise or organization willing to adopt this must carry out a careful planning and demonstrated a good understanding of the technologies involved. The results of the experimental evaluation indicated that the average rating score is 72.0 % for the participants involved in this study. This implies that the idea of IAMSys is a way to mitigating security challenges associated with authentication, authorization, data protection and accountability if properly deployed

Comparison of advanced authorisation infrastructures for grid computing

The widespread use of grid technology and distributed compute power, with all its inherent benefits, will only be established if the use of that technology can be guaranteed efficient and secure. The predominant method for currently enforcing security is through the use of public key infrastructures (PKI) to support authentication and the use of access control lists (ACL) to support authorisation. These systems alone do not provide enough fine-grained control over the restriction of user rights, necessary in a dynamic grid environment. This paper compares the implementation and experiences of using the current standard for grid authorisation with Globus - the grid security infrastructure (GSI) - with the role-based access control (RBAC) authorisation infrastructure PERMIS. The suitability of these security infrastructures for integration with regard to existing grid technology is presented based upon experiences within the JISC-funded DyVOSE project

DyVOSE project: experiences in applying privilege management infrastructures

Privilege Management Infrastructures (PMI) are emerging as a necessary alternative to authorization through Access Control Lists (ACL) as the need for finer grained security on the Grid increases in numerous domains. The 2-year JISC funded DyVOSE Project has investigated applying PMIs within an e-Science education context. This has involved establishing a Grid Computing module as part of Glasgow University’s Advanced MSc degree in Computing Science. A laboratory infrastructure was built for the students realising a PMI with the PERMIS software, to protect Grid Services they created. The first year of the course centered on building a static PMI at Glasgow. The second year extended this to allow dynamic attribute delegation between Glasgow and Edinburgh to support dynamic establishment of fine grained authorization based virtual organizations across multiple institutions. This dynamic delegation was implemented using the DIS (Delegation Issuing) Web Service supplied by the University of Kent. This paper describes the experiences and lessons learned from setting up and applying the advanced Grid authorization infrastructure within the Grid Computing course, focusing primarily on the second year and the dynamic virtual organisation setup between Glasgow and Edinburgh

Experiences in teaching grid computing to advanced level students

The development of teaching materials for future software engineers is critical to the long term success of the grid. At present however there is considerable turmoil in the grid community both within the standards and the technology base underpinning these standards. In this context, it is especially challenging to develop teaching materials that have some sort of lifetime beyond the next wave of grid middleware and standards. In addition, the current way in which grid security is supported and delivered has two key problems. Firstly in the case of the UK e-Science community, scalability issues arise from a central certificate authority. Secondly, the current security mechanisms used by the grid community are not line grained enough. In this paper we outline how these issues are being addressed through the development of a grid computing module supported by an advanced authorisation infrastructure at the University of Glasgow

Threat Modelling for Active Directory

This paper analyses the security threats that can arise against an Active Directory server when it is included in a Web application. The approach is based on the STRIDE classification methodology. The paper also provides outline descriptions of countermeasures that can be deployed to protect against the different threats and vulnerabilities identified here
