Virtual Computing Question.. Answer the following question that listed below.. also provide one Reference This scenario involves the integrity portion of the CIA Triad. The integrity portion of the triad deals with maintaining the accuracy and trustworthiness of data over its life cycle. Jim, the virtual server manager, wants to send three separate documents to users on his virtual server; one document for each person. Therefore, each document has to travel from the server to a client machine on the network. The virtual machine manager is Oracle VirtualBox and each client has a different operating system on their system: one has Fedora Linux, one has Microsoft XP, and one is running Mac OS X. What will ensure these documents travel to their recipients without being changed en route? What precautions should Jim take before sending them? Also, will one client operating system be more at risk of their packet being sniffed or changed? Solution The docs will be reached on client site without being changed which is ensured by Data Encapsulation provided by TCP/IP Protocol and by resilient and scalable networks, Encryption also plays an important role in this Jim has to take the following steps First use the VPN Second use security concerns like Encryption, password protection It depends upon the schema which a OS applies for data decryption because the data transmission doesnt care about the OS of the Recipient, so the risk always lies on the client side not on the medium .

Virtual Computing Question-- Answer the following question that listed.docx

Cloud services help individuals and organization to use data that are managed by third parties or another person at remote locations. With the increase in the development of cloud computing environment, the security has become the major concern that has been raised more consistently in order to move data and applications to the cloud as individuals do not trust the third party cloud computing providers with their private and most sensitive data and information. This paper presents, the migration of virtual machine to improve the security in cloud computing. Virtual machine (VM) is an emulation of a particular computer system. In cloud computing, virtual machine migration is a useful tool for migrating operating system instances across multiple physical machines. It is used to load balancing, fault management, low-level system maintenance and reduce energy consumption. Virtual machine (VM) migration is a powerful management technique that gives data center operators the ability to adapt the placement of VMs in order to better satisfy performance objectives, improve resource utilization and communication locality, achieve fault tolerance, reduce energy consumption, and facilitate system maintenance activities. In the migration based security approach, proposed the placement of VMs can make enormous difference in terms of security levels. On the bases of survivability analysis of VMs and Discrete Time Markov Chain (DTMC) analysis, we design an algorithm that generates a secure placement arrangement that the guest VMs can moves before succeeds the attack.

Multi-cloud is an advanced version of cloud computing that allows its users to utilize different cloud systems from several Cloud Service Providers (CSPs) remotely. Although it is a very efficient computing facility, threat detection, data protection, and vendor lock-in are the major security drawbacks of this infrastructure. These factors act as a catalyst in promoting serious cyber-crimes of the virtual world. Privacy and safety issues of a multi-cloud environment have been overviewed in this research paper. The objective of this research is to analyze some logical automation and monitoring provisions, such as monitoring Cyber-physical Systems (CPS), home automation, automation in Big Data Infrastructure (BDI), Disaster Recovery (DR), and secret protection. The Results of this research investigation indicate that it is possible to avoid security snags of a multi-cloud interface by adopting these scientific solutions methodically.

Providing user security guarantees in public infrastructure clouds

Kamal Spring

The infrastructure cloud (IaaS) service model offers improved resource flexibility and availability, where tenants – insulated from the minutiae of hardware maintenance – rent computing resources to deploy and operate complex systems. Large-scale services running on IaaS platforms demonstrate the viability of this model; nevertheless, many organizations operating on sensitive data avoid migrating operations to IaaS platforms due to security concerns. In this paper, we describe a framework for data and operation security in IaaS, consisting of protocols for a trusted launch of virtual machines and domain-based storage protection. We continue with an extensive theoretical analysis with proofs about protocol resistance against attacks in the defined threat model. The protocols allow trust to be established by remotely attesting host platform configuration prior to launching guest virtual machines and ensure confidentiality of data in remote storage, with encryption keys maintained outside of the IaaS domain. Presented experimental results demonstrate the validity and efficiency of the proposed protocols. The framework prototype was implemented on a test bed operating a public electronic health record system, showing that the proposed protocols can be integrated into existing cloud environments.

Key-exposure resistance has always been an important issue for in-depth cyber defence in many security applications. Recently, how to deal with the key exposure problem in the settings of cloud storage auditing has been proposed and studied. To address the challenge, existing solutions all require the client to update his secret keys in every time period, which may inevitably bring in new local burdens to the client, especially those with limited computation resources such as mobile phones. In this paper, we focus on how to make the key updates as transparent as possible for the client and propose a new paradigm called cloud storage auditing with verifiable outsourcing of key updates. In this paradigm, key updates can be safely outsourced to some authorized party, and thus the key-update burden on the client will be kept minimal. Specifically, we leverage the third party auditor (TPA) in many existing public auditing designs, let it play the role of authorized party in our case, and make it in charge of both the storage auditing and the secure key updates for key-exposure resistance. In our design, TPA only needs to hold an encrypted version of the client’s secret key, while doing all these burdensome tasks on behalf of the client. The client only needs to download the encrypted secret key from the TPA when uploading new files to cloud. Besides, our design also equips the client with capability to further verify the validity of the encrypted secret keys provided by TPA. All these salient features are carefully designed to make the whole auditing procedure with key exposure resistance as transparent as possible for the client. We formalize the definition and the security model of this paradigm. The security proof and the performance simulation show that our detailed design instantiations are secure and efficient.

Security as a Service Model for Cloud Environment

KaashivInfoTech Company

Cloud computing is becoming increasingly important for provision of services and storage of data in the Internet. However there are several significant challenges in securing cloud infrastructures from different types of attacks. The focus of thisPaper is on the security services that a cloud provider can offer as part of its infrastructure to its customers (tenants) to counteract these attacks. Our main contribution is a security architecture that provides a flexible security as a service model that a cloud provider can offer to its tenants and customers of its tenants. Our security as a service model while offering a baseline security to the provider to protect its own cloud infrastructure also provides flexibility to tenants to have additional security functionalities that suit their security requirements. The paper describes the design of the security architecture and discusses how different types of attacks are counteracted by the proposed architecture. We have implemented the security architecture and the paper discusses analysis and performance evaluation results.

What is a service host file? Solution 1,Windows and .net framework include a number of deployment technologies which include: a)clickonce deployment:applications are published to and deployed from the web here.it provides an integration between start meny and program control pannel.Moreoever it supports automatic updates when new versions are released.It also provides the registration of file extensions. b)windows installer: Windows Installer allows the various applications to be packaged as self-contained executables that can be easily distributed to clients and run. Moreoever it simplifies the installation and uninstallation of the programs. 2)in order to select and add a table in report designer we will a)First we will open the client report definition (.rdlc) file in graphical design mode. b)Next in the Toolbox, click on the Table. c)Finally click the design surface of the report. now after a given table is on the report, wecan move it by pointing to the shaded border of the table and dragging it to a new location. 3)The hosting code is present in the service host file.Service host framework is basically used to associate the factory which is used to produce the service which is to be hosted and also includes the various other programming aspects which are being required to access or compile the hosting code which is basically present in the .svc file that we are talking about here. .

Week 2 Discussion- I need help understanding the following question- C.docx

mtruman1

Week 2 Discussion: I need help understanding the following question: Consider the place where you live (city, town, county, state etc.) and think about local housing market, what can we say about Demand and Supply for housing as related to a geographic area? How would we tie this into current economic conditions? Hint: Consider factors (e.g more green jobs, tourism, etc) that contribute to stable/rising housing market and factors (e.g. disaster prone areas, pollution, etc.) that lead to the opposite. You can all use T-I-P-E-N and P-R-E-S-T to explain why housing prices vary from one city to another. Solution One could drive until the household qualifies for a mortgage. The willingness to migrate for affordable housing considerably expands the geography of supply. The result is sprawl. Sprawl bad. The push for greater density is normative, a geographic fetish. Expanding the geography of supply is not OK. Suddenly, the real estate market doesn\'t look so agnostic. Regardless, sprawl is one way a region can deal with a problem of housing affordability. Migration is a lot nimbler than changes to zoning and casting bedroom eyes at real estate developers. I would hope that all readers appreciate that geographic scale impacts the supply of housing. The point of greater density is to make a hot residential neighborhood affordable, not an entire metro area. Proponents of greater density promote the geographic distortion of housing supply, not a less regulated real estate market. The dense mixed-use urban utopia of walkability is this generation\'s suburban idyll. .

We will assume the universe is expanding at a constant rate- At t - t0.docx

mtruman1

We will assume the universe is expanding at a constant rate. At t = t0Â another galaxy is a distance D0Â away from us as shown in the diagram. For the purposes of this exorcise it will be easier to think of the other galaxy being at 0 and we are moving away from it, with us being at location D0Â at t0. 1. If we assume the two galaxies were at the same location a t = 0, find an equation for the distance between the galaxy as a function of time, D(t). 2. Find the speed at which the galaxy are moving apart. 3. At t0Â light leaves the galaxy at 0 headed for us at a speed c. How long does it take the light to reach us? Do not forget to include the fact that we are moving away from the other galaxy, which means the light will have to travel farther than D0Â to reach us. Solution if we assume constant rate of expansion of the universe then for a distance s between two galaxies their rate of seperation is ds/dt = k ( where k is a constant) given distance at t = to is s = Do distance at t = 0 is s = 0 distance at t = t is s = D(t) hence ds/dt = k s = kt + c ( where c is another constant) hence Do = k*to + c 0 = c hence k = Do/to hence s = Do*t/to 1. D(t) = Do*t/to 2. speed at which they are moving apart = v v = ds/dt v = d(D(t))/dt = Do/to 3. at to, light leaves galaxy at x = 0 it reaches us at time t = to + t then time taken for it to travel distace = t distance = Do + v*t hence Do + v*t = c*t hence t = Do/(c - v) = Do/(c - Do/to) .

We normally think of the arts as very different from technologies in s.docx

mtruman1

We normally think of the arts as very different from technologies in spite of the fact that art (with perhaps a few exceptions) is practiced with the help of technology. This practice creates interdependence between technology and art. To what extent does art respond to, or is shaped by, the technology that enables it? To what extent have advanced and accessible digital technologies, such as websites, digital photography, and YouTube, changed the relationship between art and technology? Are these technologies reshaping our attitudes toward artists? Solution Ans; Art, to a very large extent, is shaped by the technology that enables it. In fact it is technology that led to invention of portable paint tubes, a pre-requisite for most art forms. Technology provides a medium, a way to the artists to express themselves. For example silkscreen painting as an art form is a technological find. The digital revolution which is taking place, thanks to the new and emerging digital technologies is strengthening the bond between art and technology. Digital technologies helps artist innovate and apply new methods to present their art. For example \"the petting zoo by mimimaforms\" uses technology to showcase their art work. (this can be viewed on youtube). Yes, these technologies are re-shaping our attitudes toward artists. Earlier artists and their art works were considered exclusive, meant for the rich people. With technologies like websites, youtube etc. even common people belonging to the middle class can have access to the artworks and this has changed attitude as artists and their art works are now considered more inclusive. .

We discussed how the processor routes data between internal components in the Chip. Using simple Register Transfer Language notation (t0: dest leftarrow source), show how the following instruction would be processed if we have the indicated transfer registers in the route the signals will take. (The instruction has been decoded and IR2 has the needed address of variable1.) IR2 - instruction register holding the address MAR - memory address register MDR - memory data register REGn - internal register (in control unit) Here is the instruction: mov r12, [variable 1] Solution The Register Transfer Language RTL is a simple, human-oriented language to specify the operations, register communication and timing of the steps that take place within a CPU to carry out higher level (user programmable) instructions. The operand : MOV Description : The move the input operand at a register to the second by a word copy The operations are in data movement MOV MVN Examples: MOV ro, r1 MOVS r2, #10 NVNEQ r1, #0 Now we have to processed the following register transfer language instruction MOV r12, [variable1] That variable may be register for example: R2, R0, R5, etc….. The some example for MOV R12 MOV R12, R4 = R4 rotated the value MOV R12, R0, LSL#2 = Shift R0 left by 2 .

We normally think of the arts as very different from technologies in spite of the fact that art (with perhaps a few exceptions) is practiced with the help of technology. This practice creates interdependence between technology and art. To what extent does art respond to, or is shaped by, the technology that enables it? To what extent have advanced and accessible digital technologies, such as websites, digital photography, and YouTube, changed the relationship between art and technology? Are these technologies reshaping our attitudes toward artists? Solution Interest in new technologies on the part of artists has always been an important element of the development of art, but it was only in the 1960s that the creative practices known today as the main reference point for technological art were established. Such new initiatives appeared in the Poland of the 60s, during the Thaw period, when the attitudes towards activities at the interface of art, design, and technological development were much more accepting. This includes, among others, works created at the Polish Radio Experimental Studio, as well as the artistic practices stemming from Mieczysaw Porbski\'s seminars, devoted to the relationship between art, science, and technology (participants included Ryszard Winiarski, Feliks Falk, and Grzegorz Kowalski). 1 Other artistic phenomena involving art and technology include some works created at the Workshop of the Film Form, and the later solo works by such Polish artists as Krzysztof Wodiczko orZbigniew Rybczyski. .

Why or why not? A) 25 + baseAmount; B) baseAmount = 2 * baseAmount; C) baseAmount + 25; D) baseAmount + baseAmount. Solution D) baseAmount + baseAmount. Because both are of type Money .

We have two oscillators- used to measure time- One is a vertical mass-.docx

mtruman1

We have two oscillators, used to measure time. One is a vertical mass-and-spring system. The other is a simple pendulum. On earth the two systems have the same period. How do their periods compare on the moon? A. Both periods become longer. B. only the pendulum\'s period becomes longer C. Only the mass-and-spring\'s period becomes longer D. Neither period changes at all. E. none of the above If a mass hangs from a vertical spring and is moving up and down, you take one video of the motion on earth and then take another video of its motion on the moon, can you tell the difference between the two motions? Solution time period of simple pendulam= 2*pi sqrt(l/g) so time period inversly propotional to gravitaion constant. time period of verticle ossilator= 2*pi sqrt(k/m) so time period does not depend on g. we knows g of moon < g of earth. so on moon g is less then that of earth. so g decreases, so time period of pendulam increase as time period of pendulan is inverse of sqrt g. and time period of oscillator remains the same. so option B. only pendulam\'s timeperiod becomes longer. .
