Introduction
Registering the unique identity of an application's users is nearly ubiquitous among all software today. A formalized method of allowing an application’s user to register their identity with an existing set of data, stored outside of your application, is known as OAuth (open standard for authorization). This method allows an application to gain access to the user’s data from a third-party server, providing the unique identification without requiring the user to step through a registration process to provide such. To algorithm of the OAuth method one must consider the three steps it requires: fetching the request, user authorization, and fetching the access [1].
Fetching an initial request token
Initially the OAuth process calls an authorize function which redirects the OAuth provider being used. The list of OAuth providers is too long to go through. We will consider a generic provider for the description of this algorithm. This authorize function begins what is referred to as the OAuth dance, redirecting the user to the third-party. Nothing is needed to store th...
The authorization role is used by providers that make access decisions for the requested resources based on the effective user identity context. This identity context is determined by the authentication provider and the identity assertion provider mapping rules. Evaluation of the identity contexts user and group principals against a set of access policies is done by the authorization provider in order to determine whether access should be granted to the effective user for the requested resource [14]. Out of the box, the Knox Gateway provides an ACL based authorization provider that evaluates rules that comprise of username, groups and ip addresses. These ACLs are bound to and protect resources at the service level. That is, they protect access to the Hadoop services themselves based on user, group and remote IP address [14]. To provide a common authorization framework for the Hadoop platform, providing security administrators with a single administrative console to manage all the authorization policies for Hadoop components is the goal of Hadoop’s developers.

The process of authenticating users is transparent to the user dialing in. The way it works is that a user places a call into a remote-access server and a Point-to-Point Protocol session is initiated. The RAS or VPN takes authentication information, such as a user name and password, and passes this information to the RADIUS server.
What concerns the government of the United States most is the security of the critical infrastructure from the cyber threats. The nation is depending heavily on the technology in most of its critical sectors to keep it up and running. Thus, this makes its more vulnerable to cyber-attacks from outsiders and insiders. Therefore, its protection must be a priority.
In view of emergence in cloud computing and cloud based identity management providers, the need for implementing SAML protocol is imperative. In addition, with the proliferation of SaaS (Software as a Service), and other web based applications, identity management has become challenging for various enterprises. Handling so many usernames and passwords for your intranet, cloud, webmail, HR system, and other resources is nothing but bothersome especially when your workforce is huge. This is where SAML is desperately needed. Many hosted services providers support SAML for authentication including Google Apps, Salesforce.com, Zendesk and Zoho. Thousands of large enterprises have adopted it as their standard protocol for their communicating identities across their network environments.
My project mainly focuses on relatively new field of study in Information Technology known as cryptography. This topic will take an in-depth look at this technology by introducing various concepts of cryptography, a brief history of cryptography and a look at some of the cryptography techniques available today. This will have a close look at how we can use cryptography in an open-systems environment such as the Internet, as well as some of the tools and resources available to help us accomplish this.
The project is to create an online application system to manage third party accounts which staff members of nursing homes use to access medical records of residents living at the facilities. This is a system that requires a high level of user interaction since the account creation is a lengthy process requiring several levels of credentialing before an account can be created. A request for an account starts when an executive director or other personnel at facility requests an account on behalf of certain staff members such as a medical doctor, dietitian or a nurse who need access to such resident records, visits the facility. These resident records
This step is also known as two-factor authentication. It adds an additional layer of protection to the user’s password. It requires users to have extra credentials other than just a password to access an online account. Two-step verification normally requires users to know their password, and have a specific mobile device. Some social media have started introducing the two-step verification for example LinkedIn and twitter. Two-step verification reduces the chances of hackers bumping into your privacy as it critically make sure that only the authenticated user have access to it.
Token systems have a high success rate and have been shown to improve behaviors within the classroom. Most statistics reported undesirable behavior was reduced to low occurrences. (Donaldson, DeLeon, Kahng, & Fisher, 2014)
As we evolve in the information age, online privacy rights have grown over the past years. In 1986, a federal law was passed to protect an individual’s electronical information. “This law was produced to make a fair balance among the privacy expectations of citizens and the legitimate needs of law enforcement” (EPIC). With the Internet developing intensely, there is a great deal at stake such as the theft of your identification. But where it all begins is when you access the Internet. This is the first step in being aware of your privacy because you go through the process in signing up with an Internet Service Provider (ISP). With this process you have a IP address attached to your ISP. This is the primary step on how your information starts
Cookies provide a means for Web applications to store user-specific information. It is stored with the help of cookies. For example, when a user visits a site, to store user preferences or other information, that site can use cookies. When the same Web site is being visited by the same user another time, the information that has been stored earlier can be retrieved by the application
ABSTRACT : This paper describes the basic threats to the network security and the basic issues of interest in designing a secure network. it describes the important aspects of network security. A secure network is one which is free of unauthorized entries and hackers. INTRODUCTION
Authentication: The process of proving one's identity. (The primary forms of host-to-host authentication on the Internet today are name-based or address-based, both of which are notoriously weak.)
The book is structured into four parts: Part 1 discusses the fundamentals of Internet security and privacy, Part 2 specializes in privacy while on the World Wide Web, Part 3’s topics are e-mail security and privacy, and Part 4 discusses the ways in which to secure a computer. Following the structure of the book, I will review and summarize the most important aspects of the parts and chapters in chronological order.
