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

Describe NoSQL and its purpose. Explain how it is used differently than MySQL. M12 jan30 az

Describe NoSQL and its purpose. NoSQL is a highly scalable and reliable non-relational databases designed to maintain high performance and to be highly cost efficient for workloads of any scale, from the smallest to the largest internet-scale applications. It is also used to build a new kind of database for "unstructured" information that comes spilling off the Internet with each passing second. It is capable of handling large amounts of data du to the fact that they use flash storage rather than traditional spinning disks. These solid-state drives can provide single-digit millisecond response times. Explain how it is used differently than MySQL. MySQL database is a relational database that stores data in neat rows and columns, and it's designed to run on a single machine, while NoSQL database can store data in a more flexible way and is designed to scale across a very large number of machines. "SQL databases are like automatic transmission and NoSQL databases are like manual transmission. Once you switch to NoSQL, you become responsible for a lot of work that the system takes care of automatically in a relational database system. Similar to what happens when you pick manual over automatic transmission. Secondly, NoSQL allows you to eke more performance out of the system by eliminating a lot of integrity checks done by relational databases from the database tier. Again, this is similar to how you can get more performance out of your car by driving a manual transmission versus an automatic transmission vehicle." http://stackoverflow.com/questions/2559411/sql-mysql-vs-nosql-couchdb

 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.

Are any corporate databases and networks safe? Should consumers be wary about providing personal data online? How valuable is data stored online? May 11 soo

Are any corporate databases and networks safe? According to the article, they mentioned that no corporation databases are not completely safe and secure enough to protect personal information. There are too much false which makes network perfectly safe. It is very large storage and contains a lot of personal information. If the network is too big, they can't manage the network well and all the weaknesses will occur. The hackers will aim to hack the corporate databases because it has a lot of information therefore; it is not actually very safe. Should consumers be wary about providing personal data online? Yes, consumers should be wary about providing personal data online, because all services that store the online data are all under risk of being hacked, and the data compromised. Once the sensitive information is compromised, the user is more vulnerable to scam attacks through e-mails, as well as have their bank accounts or other user accounts online hacked. consumers should be a warning to be wary about providing personal data online because no corporate networks are frequently attacked by hackers and no matter how diligently their administrators work to protect them or how many protections are put n place, no network is perfectly secure. Even Sony' security systems are not perfect at all. Therefore, people have to be wary about providing personal data online How valuable is data stored online? Data stored online is very valuable, especially sensitive information such as ID numbers and bank/credit card numbers. Other personal data such as names, passwords, and security question answers are useful for hackers, and can be easily used for impersonation on other sites to hack into user accounts for further bad intentions.

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.

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.

Identify one ITGS social/ethical concern in the article - Intellectual property 4. Describe ITGS terminology and systems. - Apps: Apps is an abbreviation for application. An app is a piece of software. It can run on the Internet, on your computer, or on your phone or other electronic device. - Copyright: a set of exclusive rights granted to the author or creator of an original work, including the right to copy, distribute and adapt the work. The App Store is some kind of a database for iPhone, iPod touch, and iPad created by apple that allows users to browse, download and install app on their devices. Applications in an app store can vary in cost, from free downloads to quite costly ones, depending on who developed the application and its purpose. Software Apps, E-books that are sold through the app store are pirated. This software is basically electronic books, similar to real life books, where its contents are stored online. This Japanese copyright infringement is done through software that is uploaded through the internet that can be downloaded for a price. However, the payment is delivered to the offender, not the original person who owns the contents' rights. These pirated apps are Chinese -based language apps which plays a role in delaying the notice of the copyright infringement. 5. If possible, describe a solution to the concern (issue). Illegal distribution of copyrighted property should be banned. However, the massive infringe of the law is common in China. There should be more strict policy and laws in national level to reduce the number of these issues, such as measurement and specified steps of installing and removing application to satisfy companies wor

Why are iphones tracking people? april 28' cream

Why are iphones tracking people? This is the issue of storing user's location data in unencrypted file. The file, named "consolidated.db," is an unencrypted SQLite database that can be found in the devices' file systems and in the iOS backup files created and updated by iTunes every time an iPhone or 3G iPad is synced. Since, we know that Apple is actually collecting location and some information on iphone that's why iphone is not safe at all. Although the file isn't immediately accessible on the device itself, it can be accessed on a jailbroken device via the iTunes-generated backup file. It also could potentially be accessed using other tools that allow you to explore an iOS device's file system while it's attached to a computer.
