What does cloud computing deal with? Cloud computing deals with all the technology and support for the infrastructure of the cloud such as networking, database, storage, and management applications. Describe each of the characteristics cloud services must have. Fshared services (with standard framework and shared application programming interface (API)) - these services can be shared in order for all users to have access to them. Fstandard user interface - Web browsers to have access to the cloud services. Fself-service - Users must help themselves by self service when it comes to doing cloud services since actions are carried over the computer, not from human to human. Fservice metering - The Charge of the usage of the cloud services. Faccess over the internet - The medium of having access to the internet, as well as other places over the internet. Explain horizontal and vertical services. Horizontal Services - cloud applications, cloud storage, cloud servers, and cloud collaboration. These horizontal services are the services that are spread around horizontally as the infrastructure, and the base of the cloud service. It provides the technology and memory for clouds for example. Vertical Services - government services, cloud entertainment, cloud publishing and online ad networks, cloud healthcare, and cloud telecommunications. These vertical services are basically what we use the cloud services for, which field they are in, and how they are used. Define each layer of services. Infrastructure as a Service (IaaS) - This is a service usually from outsourcing done by an organization so that the actual infrastructure to hold the storage, hardware, and other components are stored elsewhere. Why is bandwidth important? Internet bandwidth will drive the popularity of cloud services in the country, as businesses and consumers will demand more services as bandwidth increases. Speedy network reliability is needed for "megabit-per-second" services.

This is a disposable email that only lasts for one hour then erases itself. This could come in handy if you have to give an email address to make a game account you could use it so that you don't get spammed from the game site. Also it would make it impossible to track information sent from that email address to someone because it erases itself after one hour after being activated. You do not have to create your name because the site gives you an example. When I opened the site it told me that my email address was ready for use and was (owbjehey@guerrillamailblock.com) however you could change the name and use that as long as it has not been used before or is in use now.

Explain the problem and solution. august 30 all alec

The device is designed to absorb and feed on micro droplets of water. However if someone were to step in a large puddle of water the device could be over loaded and burnout. Also with the problem of how to transfer the energy a cable would work the best because if you use wifi or Bluetooth other devices could pick up that signal and steal the energy supply for their own use. A solution to the way power is generated it to do something similar to the Japanese train station and make the pad in the shoe absorb shockwaves from each step instead of the micro water molecules also if it were shock absorbent it could be but into a waterproof case so that it can withstand rain and puddles.

Describe the steps for removing malware. All September 2 Champ

- First, you must know that your computer is really having malware. If your computer slow down, maybe it just doesn't have enough RAM. You can check by using system cleaning tool called CCleaner, it is a best known for cleaning out files, cookies, and also can clean your hard drive. After using CCleaner, you should restart your computer. - run the Anti-Virus scan and try to restore your system. By doing so, you will need system backup, to save your important documents. If you did not back up, you can use Malwarebyte's Anti- Malware and try deep scan. If the scan still doen't work, you might have to spend sometime uninstalling things that you doesn't want but it is not so affective because most of them are not able to uninstall. It is more effective to use free virus scan. - Use Virus Scanning Tools 1. Kaspersky- it will tell you the infection. It takes about two hour depending on your software. 2. Norton Power Eraser- It will scan and clean your computer for free. 3.Trend Micro HijackThis- It can generate log and you can post these log in forum such as Bleepingcomputer.com or Geekstogo.com where experts can view your post and they might give you some advices you.

What is the value of this? all sept 29 Jang

The crime map is a site that shows the amount of crimes committed in an area. The map gives specific information about what kind crime was committed, the location and time of the crime. The site also gives data of places that crimes do not happen frequently. This crime map website can be really useful for avoiding crime scenes and being aware of crimes that are happening in your neighborhood. If you want to move to a new place you can look at the crime map to see if your new neighborhood is safe and crime free. This site is still on beta and only have information on few states in America. I think a lot of people would use this site if it have data for all the countries in the world. However keeping up with new information everyday would be very hard because there are so many crimes happening all over the world and the site would need to be updated every few minutes.

Explain why Google considers the information created in social networks to be so important. M12 Sept 1 nat

Basically, what people do on social networks are; like people's statuses, comment on others' pictures, retweet others' statuses and etc. This can help companies like Google determine what the user might be interested in, as these activities on social networks sites reflect the users' behaviour online. Moreover, we tend to show to other users what you are interested in, (like liking fan pages)therefore a lot of the information companies like Google can get out from these websites are accurate. They can then put sites that they might take interest in at the top (first page), which may be more efficient for the user looking for that information, and the website itself.

1. Identify the scenario. Business 2. Describe a social/ethical concern and the relationship of one primary stakeholder to the IT system in the article. Security is a social/ethical concern because it regards the security of the Database Servers that are used to store the Domain Names and IP addresses. With insufficient security, the database security can be breached by outsiders and be altered. The primary stakeholder is Group NBT, and is the domain name management firm of NetNames and Ascio whose DNS Databases were compromised in this attack. Their SQL commands were infiltrated by the hackers, so that the information stored on their DNS Database was altered, that made website visitors be re-directed to spam websites. 3. Describe the IT concepts and processes. Domain Name System (DNS) - The address book for the website that links the URL of websites to IP address numbers that computers use to visit a website. IP Address - The numbers that are separated by period dots that make up a website's numerical address of its location. (DNS) Database - A database is a massive spreadsheet with numerous data types and forms used to store large amounts of data (in this case, websites' domain names URL and their respective IP addresses.) SQL Injection - SQL stands for Structured Query Language, used for database manipulation. This is a hacking method by using the various layers present in SQL commands, by 'injecting' a hidden command that enables to create a loop hole for access and change the database information. This includes changing strings of commands in the original SQL command into malicious commands, that are executed when the altered SQL command is executed. http://msdn.microsoft.com/en-us/library/ms161953.aspx

4. Explain the relationship between the IT system referred to in the article and the concern presented above. The security of the DNS Databases run by NetNames and Ascio (two subsidiaries of domain name management firm Group NBT) is a concern. Their SQL commands were being altered and compromised, which resulted in the altered domain names and IP address links. Their relationship is that the concern is the IT system's (in this case the Database's) security. The IT system, Group NBT's Database, has a concern over it's security. The DNS Database system has a security concern because the hackers were able to alter the paths of redirecting certain websites to scam websites instead through a SQL Injection attack that manipulates the SQL command used to manipulate the domain name database. 5. Describe and evaluate the impact of a social/ethical issue on the stakeholders The social/ethical issue is security. The stakeholders are Vodafone, the Daily Telegraph, UPS, and four other websites, Turkish hackers (Turkguvenligi), and internet users who visited those seven websites within the hacking duration. This has an impact on their security issue because their database has already been compromised once, and unless they create a new system of security to prevent SQL injections, they will never be able to know when someone is changing their SQL command strings. They need to have someone constantly monitoring their SQL to see if there are any changes. The security issue impacts Group NBT because it makes their customers that use their services doubt the secure service because hackers were able to alter the redirection of customers to scam websites instead of their respective website. Therefore security, to a large extent, has an impact on Group NBT. 6. Explain and evaluate one solution to the issue identified. A solution to the issue identified by NBT was to further review their Database system to ensure customers of a more secure service, since it is impossible for a

Identify one ITGS social/ethical concern in the article. Security 4. Describe ITGS terminology and systems. Virtual private network- a network that is constructed by using public wires to connect nodes. For example, there are a number of systems that enable you to create networks using the Internetas the medium for transporting data. These systems use encryption and othersecurity mechanisms to ensure that only authorized users can access the network and that the data cannot be intercepted. http://www.webopedia.com/TERM/V/VPN.html Hacking- the practice of modifying computer hardware and software to accomplish a goal outside of the creator's original purpose. http://www.wisegeek.com/what-is-computer-hacking.htm Virtual servers- a Web server, that shares computer resources with other virtual servers. Instead of requiring a separate computer for each server, dozens of virtual servers can co-reside on the same computer. http://www.webopedia.com/TERM/V/virtual_server.html E-mail Server - A computer server that acts as the supplier and sender of e-mails in the network. Ecommerce - Electronic commerce, business to sell and buy online electronically. Identity Theft - The stealing of and ID, or impersonating a fake person. 5. If possible, describe a solution to the concern (issue). Gucci needs to be stricter to their employees. They need to closely monitor anyone that can access the company's financial system and any vital part. By doing so, employees would not even think of hacking the system. Moreover, educating their workers into not being tricked to activate any other fraud employee accounts. Also, improving the authorization system of employees to access information with biometrics may be helpful to increase the security of their data and network system.

1. Identify the area of impact the scenario relates to. Business and Employment 2. Identify the main stakeholders to the IT system. Amazon and companies using Amazon's cloud service 3. Identify one ITGS social/ethical concern in the article Reliability 4. Describe ITGS terminology and systems. The hardware used in this situation is the servers used to host information for companies. Amazon's cloud model is used by the connecting to the internet network. The Availability Zones are the zones that according to Amazon, are distinct locations that are engineered to prevent failures in other Availability Zones. Amazon Web Services (AWS) - Amazon's web service that provides companies with infrastructure web service platforms in the cloud. Amazon's Elastic Computer Cloud (EC2) - A web service that provides resizable compute capacity in the cloud, designed to make web-scale computer easier for company developers. Amazon's Elastic Block Store (EBS) service - this service provides block level storage volumes for use with Amazon's EC2 instances. The EBS volumes are off-instance storage that is independent from the life of an instance. http://aws.amazon.com/ 5. If possible, describe a solution to the concern (issue). A solution to the reliability concern is for businesses and companies to filter out what they plan to put on Amazon's cloud services, and what to keep in their private network within their control. Balancing the two would beneficial and can prevent a lot of damage that a failure of a server may do the company as well as its files and data stored in the cloud. Amazon explaining how their cloud service actually works and have it backs up everything should be able to calm down businesses, and regain their trust again once everything is back up and running again.

Why does apple rank low for being green? Which companies are fairly green? Why don't companies want to disclose their energy consumption? Is cloud computing green? Determine if use of IT often reduces environmental impacts or not. april 28 nat

Why does apple rank low for being green? Because of their huge electricity consumption and the increase in their consumption in a new facility, which consumes approximately the same amount of electricity 80,000 US homes. Which companies are fairly green? Yahoo, Google and Amazon. Why don't companies want to disclose their energy consumption? They don't want others to know what they did or what they had to do to reach to the position they are in now. Is cloud computing green? No, it's not green as it already accounts for approximately 2& of the world's electricity consumption, and it is predicted that it will rise. Determine if use of IT often reduces environmental impacts or not. Yes it does, because if something was electronically saved, it can save paper. Moreover, It has been said that there are less carbon emissions produced when music is downloaded of the web, rather than bought in CD stores, because you don't need to use CDs.

How can iphone be hijacked? How can a user tell if she is being SMS attacked? April 26 woo

was i supposed to do this? it wasnt on the list so i didnt know...

1. How can iphone be hijacked? The experts say that what you would know when your iphone is being hijacked is when one giveaway is if you receive a text message containing a single square character. If that happens, he suggests you immediately turn off your iPhone. The iPhone can be hijacked through a series of invisible SMS message bursts that hijacks the iPhone. The attacker would then be able to control all the functions on the iPhone, as well as continue to send messages to hijack more phones. 2. How can a user tell if she is being SMS attacked? The researchers said the hack involves sending a series of mostly invisible SMS bursts that effectively hijack an iPhone. From thereon, a hacker could control all the functions on the iPhone, such as e-mailing, dialing contacts - and, most alarmingly, sending more text messages to hijack even more iPhones. A user can tell if she is being SMS attacked if they receive a message containing a square character. Prevention measures include immediately turning off your iPhone.

Define: AWS Iaas Define and describe: Free redundancy rapid scalability server failover maintainability Explain each lesson and determine whether you agree or not with each one. May 13 az

1) Define: AWS- The Amazon Web Services (AWS) are a collection of remote computing services (also calledweb services) that together make up a cloud computing platform, offered over the Internet byAmazon.com. The most central and well-known of these services are Amazon EC2 and Amazon S3. Iaas - infrastructure-as-a-service; a way to deploy a less reliable server, quickly and without human intervention. 2) Define and describe: Free redundancy- re-deploying your application in another data center or cloud service using on-demand resources instead of having an idle redundant data center. Rapid scalability- Scalability approach that doesn't require access to AMIs that is stored on S3 or EBS. Instead, it uses the on-demand resources. This is when the system can withstand changes in transaction volume without major changes. Server failover- Virtual servers fail more frequently that physical servers, and when they do, there is less ability to recover them. Treat server failover the same way as scalability, just bring up a new server. Maintainability- Use a fully automated deployment and not a server configuration that is created manually to make it maintainability. Since, when a server configuration that is created manually and saved to a "golden image" has numerous problems such as: only the person who built it knows what is there, so if that person is gone, it can be time consuming to re-configure it. On the other hand, a fully automated deployment is not only a maintainable process, it also serves as documentation. 3) Explain each lesson and determine whether you agree or not with each one. Wrong lesson #1 The lesson where the infrastructure of the cloud is either not ready for its time to shine, or never will be. This is the lesson that explains that the infrastructure is still carried out on physical servers, just in remote areas where they are held in the physical data center in large numbers. These physical server

 Explain  NoSQL= NoSQL is a category of database engines that do not support the SQL (Structured Query Language) in order to achieve performance or reliability features that are incompatible with the flexibility of SQL. - http://stackoverflow.com/questions/4154635/what-is-nosql-what-is-purpose-of-nosql-where-can-i-get-sufficient-material-on-n  Non-relational database= a non-relational database developed by Damien Katz, now the chief technology officer for Couchbase. The company claims that Mobile Couchbase is the first non-relational, or NoSQL database, built for iOS. - http://stackoverflow.com/questions/202819/what-is-an-example-of-a-non-relational-database-where-how-are-they-used  Explain the advantages of CouchDB's noSQL - CouchDB and noSQL architecture has a number of advantages that make it attractive to iPhone applications developers, the company asserts. - CouchDB= Efficient use of working memory, Amount of storage space (takes up relatively minimal, under 20 megabytes download size limit imposed by many people CouchDB's NoSQL has advantages such as its synchronization capabilities with minimal coding. Data can be automatically synchronized across a network. The app can store data created on the phone itself, all the while also synchronizing the same data with a cloud service or a data center. The storage space taken up by CouchDB's NoSQL has efficient use of working memory. When it is embed in an app, it can still keep the app to be under the 20 mb download limit, and doesn't drain the battery.

Read Heads-up. Describe two guidelines from each section that you think are relevant advice. May 9 kuni

Share with care Your online actions can have real-world consequences. The pictures you post and the words and the words you write can affect the people in your life. Think before you post and share. The advice, mainly for children, is that before you click to send email or when you're ready to post or send a message or a photo, download a file, game or program, or shop for something-stop for a second. Think about things like: Do you know and trust who you're dealing with-or what you're sharing or downloading? How will you feel if your information ends up somewhere you didn't intend? Get someone's okay before you share photos or videos they're in. Online photo albums are great for storing and sharing pictures of special events, and camera phones make it easy to capture every moment. Stop and think about your own privacy-and other people's-before you share photos and videos online. It can be embarrassing, unfair and even unsafe to send or post photos and videos without getting permission from the people in them. Interact With Tact Avatars are people too. When you're playing a game or exploring an online world where you can create a character and interact with others, remember real people are behind those characters on the screen. Respect their feelings just INTERACT WITH TACT like you would in person. Remember that your character or avatar is a virtual version of you-what does it tell people about you and your interests? Speak up. If you see something inappropriate on a social networking site or in a game or chat room, let the website know and tell an adult you trust. Using Report Abuse links can help keep sites fun for everyone. The Protection Connection Learn about social mapping. Many mobile phones have GPS technology, and there are applications that allow you to find your friends-and allow them to find you. Use GPS and social mapping apps only with people you know personally and trust. Take advantage of privacy features in

Explain the issues that are in common with both Amazon and Sony? Explain the reasons that cloud computing will continue to grow? What could have prevented Sony from getting hacked? Describe: Rambo architecture Chaos monkey Explain the reason that data centers for cloud computing need backups? may 9 woo

1. Explain the issues that are in common with both Amazon and Sony? Issues that are in common with both Amazon and Sony are their reliability and integrity as well as its security. Amazon has just revealed that its Availability Zone in northern Virginia has failed to accommodate customers that were using their services. Sony's hack incident includes its network protection system to be unreliable. Also the security of Amazon's customer's data along with Sony's online users' data is at risk, as well as sensitive information linked to bank accounts. Both Sony and Amazon suffer a setback on their online reputation. Both companies have their servers down which affect a lot of their customers using their services. They both revived worries about the safety of storing and processing data over the Internet. The two crises have also raised questions about the speed and quality of information provided by tech companies when confronted with systems failures. This further links to the data integrity. Amazon users have said that some data may be corrupted or loss resulting from their sites crashing. Sony's users' accounts data may have been altered by unauthorized people. 2. Explain the reasons that cloud computing will continue to grow? Cloud computing will still continue to grow despite its recent incidents because the benefits users receive outweigh the risks that come with cloud computing. The outage suffered by Amazon has been rare. Also, managing one's own network is hardly a guarantee of reliability; it costs a lot of money and is high maintenance. Cloud computing provides another alternative that can save costs for businesses. Also, the recent incidents have proven that managing one's own network is not as reliable as some think considering protection issues and failure/crashes in the network itself. 3. What could have prevented Sony from getting hacked? Sony could have increased its protection system, as well as create random simulations in orde

Two passenger who are from Iranian used fake passport to board on the flight 370. Malaysiann home minister Datuk Seri Ahmad said that using Interpol's Stolen and Lost Travel Documents (SLTD) database might have slowed down the process of immigration checks at airport counters. He said the country's immigration's equipment couldn't handle the global database of 40.2 million lost passport. Later on Interpol fired back by saying that do not blame on technology or Interpol. SLTD database takes just seconds to reveal whether a passport is listed, with recent test providing results in 0.2 second. Also Interpol mention that US using more than 230 million times, UK using more than 140 million times, UAE using more than 100 million times, Singapore using 29 million times, none of the countries have complained about the time.
