The Essential Oauth Primer: Understanding Oauth for Securing Cloud Apis
THE ESSENTIAL OAUTH PRIMER: UNDERSTANDING OAUTH FOR SECURING CLOUD APIS WHITE PAPER TABLE OF CONTENTS 03 EXECUTIVE OVERVIEW 03 MOTIVATING USE CASE: TRIPIT 05 TERMINOLOGY 06 INTRODUCTION 07 THE OAUTH 2.0 MODEL 07 OAUTH 2.0 OVERVIEW USING A TOKEN TOKEN TYPE 09 RELATIONSHIP TO OTHER STANDARDS 11 USE CASES TRIPIT REVISITED TOKEN EXCHANGE MOBILE WORKFORCE 13 RECENT DEVELOPMENT 14 SUMMARY 2 WHITE PAPER ESSENTIAL OAUTH PRIMER EXECUTIVE OVERVIEW A key technical underpinning of the cloud and the Internet of Things are Application Programming Interfaces (APIs). APIs provide consistent methods for outside entities such as web services, clients and desktop applications to interface with services in the cloud. More and more, cloud data will move through APIs, but the security and scalability of APIs are currently threatened by a problem call the password anti-pattern. This is the need for API clients to collect and replay the password for a user at an API in order to access information on behalf of that user via that API. OAuth 2.0 defeats the password anti-pattern, creating a consistent, flexible identity and policy architecture for web applications, web services, devices and desktop clients attempting to communicate with cloud APIs. MOTIVATING USE CASE: TRIPIT Like many applications today, TripIt (http://tripit.com) is a cloud-based service. It’s a travel planning application that allows its users to track things like flights, car rentals, and hotel stays. Users email their travel itineraries to TripIt, which then builds a coordinated view of the users’ upcoming trips (as well as those of their TripIt friends—the inevitable social aspect). -
OK: Oauth 2.0 Interface for the Kerberos V5 Authentication Protocol
OK: OAuth 2.0 interface for the Kerberos V5 Authentication Protocol James Max Kanter Bennett Cyphers Bruno Faviero John Peebles [email protected] [email protected] [email protected] [email protected] 1. Problem Kerberos is a powerful, convenient framework for user authentication and authorization. Within MIT, Kerberos is used with many online institute services to verify users as part of Project Athena. However, it can be difficult for developers unfamiliar with Kerberos development to take advantage of its resources for use in third-party apps. OAuth 2.0 is an open source protocol used across the web for secure delegated access to resources on a server. Designed to be developer-friendly, OAuth is the de facto standard for authenticating users across sites, and is used by services including Google, Facebook, and Twitter. Our goal with OK Server is to provide an easy way for developers to access third-party services using Kerberos via OAuth. The benefits of this are twofold: developers can rely on an external service for user identification and verification, and users only have to trust a single centralized server with their credentials. Additionally, developers can request access to a subset of Kerberos services on behalf of a user. 2. Implementation overview Our system is composed of two main components: a server (the Kerberos client) to retrieve and process tickets from the MIT KDC, and an OAuth interface (the OAuth server) to interact with a client app (the app) wishing to make use of Kerberos authentication. When using our system, a client application uses the OAuth protocol to get Kerberos service tickets for a particular user. -

They’re meant to reduce the cost of management and provide better security, all while delivering an improved user experience. However, many solutions fall short, covering only one type or a subset of application types. This forces you to implement several access solutions from different vendors to cover your entire application landscape — negating the productivity and user experience benefits you hoped for. The complexity this type of implementation creates also runs counter to the Zero Trust initiatives that many organizations are undertaking Citrix Workspace helps you unify all apps and data across your distributed IT architecture to provide single sign-on to all the applications and data people need to be productive. Working with your existing infrastructure, Citrix Access Control consolidates multiple remote access solutions, like traditional VPNs or SSO solutions, simplifying management for IT and providing unified access for employees. ↑ Back to contents ← Pg. 2 | Pg. 4 → 3 Citrix.com | e-book | Choosing a Single Sign-On Solution ↓ 6 benefits of the Citrix Workspace SSO solution ↑ ← Pg. -

Securing Digital Identities in the Cloud by Selecting an Apposite Federated Identity Management from SAML, Oauth and Openid Connect
Securing Digital Identities in the Cloud by Selecting an Apposite Federated Identity Management from SAML, OAuth and OpenID Connect Nitin Naik and Paul Jenkins Defence School of Communications and Information Systems Ministry of Defence, United Kingdom Email: [email protected] and [email protected] Abstract—Access to computer systems and the information this sensitive data over insecure channels poses a significant held on them, be it commercially or personally sensitive, is security and privacy risk. This risk can be mitigated by using naturally, strictly controlled by both legal and technical security the Federated Identity Management (FIdM) standard adopted measures. One such method is digital identity, which is used to authenticate and authorize users to provide access to IT in the cloud environment. Federated identity links and employs infrastructure to perform official, financial or sensitive operations users’ digital identities across several identity management within organisations. However, transmitting and sharing this systems [1], [2]. FIdM defines a unified set of policies and sensitive information with other organisations over insecure procedures allowing identity management information to be channels always poses a significant security and privacy risk. An transportable from one security domain to another [3], [4]. example of an effective solution to this problem is the Federated Identity Management (FIdM) standard adopted in the cloud Thus, a user accessing data/resources on one secure system environment. The FIdM standard is used to authenticate and could then access data/resources from another secure system authorize users across multiple organisations to obtain access without both systems needing individual identities for the to their networks and resources without transmitting sensitive single user. -

Reputation is a fundamental tenet of online social bers and abuse them to provide fake likes or comments to their networks. People trust the information that is posted by a reputable members. We carry out a comprehensive measurement study to social media account or is endorsed (e.g., liked) by a large number understand how these collusion networks exploit popular third- of accounts. Unfortunately, reputation fraud is prevalent in online party Facebook applications with weak security settings to retrieve social networks. A number of black-hat reputation manipulation OAuth access tokens. We infltrate popular collusion networks services target popular online social networks such as Facebook using honeypots and identify more than one million colluding Face- and Twitter [29, 53, 63]. These services rely on a large number of on- book accounts by “milking” these collusion networks. We disclose line social network accounts to conduct reputation manipulation at our fndings to Facebook and collaborate with them to implement a scale. To accomplish this goal, fraudsters purchase fake accounts in series of countermeasures that mitigate OAuth access token abuse bulk from underground marketplaces [55, 57], use infected accounts without sacrifcing application platform usability for third-party compromised by malware [51], or recruit users to join collusion developers. -
