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. …show more content…
Kerberos provides a secure authentication scheme. Authentication is needed to restrict the intruders and malicious users. The major security issues discussed are privacy of the data, integrity of data and authentication mechanism which is not there in Hadoop. Hadoop supports Kerberos for authentication and many security features can be configured with the Hadoop to restrict the accessibility of the data. The data can be associated with the user names or group names in which data can be accessed. Kerberos is a conventional authentication system, improved authentication systems can be used which are more secure and efficient than
The moral philosophy best describes my personal decision making is virtue ethics (Ferrell, Fraedrich, & Ferrell, 2013). It best description of me as virtual ethics having exceptional moral character (Ferrell, Fraedrich, & Ferrell, 2013). My character displays honesty, integrity, and helpfulness (Ferrell, Fraedrich, & Ferrell, 2013). For example, a friend attempted to commit suicide as a result of a wife asking for a divorce through email (Ferrell, Fraedrich, & Ferrell, 2013). However, while working I received a phone call from him stating his desire not to live anymore (Ferrell, Fraedrich, & Ferrell, 2013). Meanwhile, I called his son to ensure that he wasn’t alone however, his son drove to the house and found his father sitting and with a

A parallel bus system is a bus system that transfers several data bits at the same time. This bus system requires wide buses because large chunks of data need to be transferred faster. Parallel buses usually have 8, 16, 32 or 64 data lines. A parallel bus system includes: ISA, PCI, VESA, and EISA buses. (Mueller, S. & Zacker, C. 1988).
Application Virtualization: Application virtualization conveys an application that is facilitated on a solitary machine to a substantial number of clients. The application can be arranged in the cloud on high-review virtual machines be that as it may, in light of the fact that a substantial number of clients get to it, its expenses are some common by those clients.
Kerberos: The Kerberos is a protocol which defines how clients interact with a network authentication service. It uses tickets as a proof of identity. This a assumption of Kerberos protocol that transactions is taking place in open network between clients and servers, where most of the clients and servers
What questions do you have about the overarching Unit 5 assignment? Although not due until the end of the class, it is important that you begin planning for this project early in the course. What are your initial thoughts about how you will approach this assignment? Explain.
1.“If, for example, students were not ultimately rewarded for spending their early adulthoods pursuing undergraduate, graduate, and professional degrees, or if the hardest-working and most productive workers were paid the same as the median worker, then citizens would have little incentive to develop expertise, to exert effort, or to excel in their work.”
It's important to gather information that is understandable by your students. The procces of gathering evendce in childrens learning can make a huge difference. there are many different kinds of assesments that help you as a teacher better educate your students. your lessons plans and what you teacer is very important to what they understand and how they learn.
My name is Betsy Eapen. I enjoyed educating and guiding patients about the importance of oral health when I was working as a Dental Assistant, and that has encouraged me to pursue Dental Hygiene as my major area of study. I always love to work in a health profession field. I enjoyed working with the people and also like the harmony in dental office. I also helped office jobs like scheduling the appointment, receiving patients in the office and keeping patient records. I believe that I am genuine and compassionate to others and those are some of my unique characteristics . I hope to learn how to talk, act and interact with different kinds of people and communities in society through this class, and hope to use these experiences to pursue
A Hadoop cluster consists a single master node and multiple worker nodes. The master node includes a JobTracker, TaskTracker, NameNode and DataNode. A slave or node acts as both DataNode and TaskTracker, though it could have data-only slave nodes and compute-only slave nodes.Hadoop requires JRE 1.6 (Java Runtime Environment)or higher. The standard shutdown scripts and start-up require Secure Shell to set up among nodes in the cluster.
Google File System (GFS) was developed at Google to meet the high data processing needs. Hadoop’s Distributed File System (HDFS) was originally developed by Yahoo.Inc but it is maintained as an open source by Apache Software Foundation. HDFS was built based on Google’s GFS and Map Reduce. As the internet data was rapidly increasing there was a need to store the large data coming so Google developed a distributed file system called GFS and HDFS was developed to meet the different client needs. These are built on commodity hardware so the systems often fail. To make the systems reliable the data is replicated among multiple nodes. By default minimum number of replicas is 3. Millions of files and large files are common with these types of file systems. Data is more often read than writing. Large streaming needs and small random needs are supported.
Hadoop is a free, java based programming framework that usually supports processing of large data sets that are in diverse computing environment. Hadoop is a cluster computation framework. Apache Hadoop is a programming framework that provides support to data intensive distributed applications with a free license. The program was inspired by Google file and Google’s MapReduce system (Eadline, 2013). According to Eadline (2013), the Hadoop technology was designed to solve various problems such as to provide a fast and reliable analysis for both complex and clustered data. Consequently, different organizational enterprises deployed Hadoop with the existing IT systems, thereby, allowing them to combine old and new data in a strong framework. The major industrial players who used Hadoop technology include IBM, Yahoo, and Google (Lavalle, Lesser, Shockley, Hopkins & Kruschwitz, 2011).
Despite the numerous advantages offered by cloud computing, security is a big issue concerned with cloud computing. There are various security issues and concerns associated with cloud computing, among them being phishing, data loss and data privacy. There are different mitigation measures that cloud pioneers are currently using to ensure data stored in the cloud remain secure and confidential as intended. Encryption is one mitigation method used to ensure security in cloud computing. According to Krutz and Vines (2010), encryption involves coding of the data stored in the computing cloud such that hackers cannot gain access to the data. Data encryption seems to be the most effective method of ensuring security in computing (Krutz and Vines, 2010). However, it is of paramount importance to note that encrypted data is usually difficult to search or perform various calculations on it.
Security Concerns: Data security is the primary concern of a financial institution like a bank. It needs to protect its customer information, their transactional data and their unstructured data in the form of emails and social media information. Hadoop system is highly transparent to the users which enables it to hide the complexity associated with its implementation. By default, the security model of Hadoop is disabled due to its sheer complexity. It also lacks encryption at storage and network levels. Because a financial institution cannot afford any sort of lapse in security, the bank has to make sure that an appropriate solution has to be found before going ahead with the implementation. A prospective solution maybe to enable the security on Hadoop but this
Abstract: Fog computing extends cloud computing, cloud computing provide data, compute, storage, and application services to end-user, also the fog computing also provide the services like data, compute ,storage and application to end user. But in cloud the main problem that occurs is security and now a days security and privacy both are main concern that needed to be considered. Fog Computing is not a replacement of cloud it is just extends the cloud computing by providing security in the cloud environment. With Fog services we are able to enhance the cloud experience by isolating users’ data that need to live on the edge. The main aim of the fog computing is to place the data close to the end user.The securityissues are mentioned in this paper.
