1. Describe the IT terms. Patented - Granted and protected by rights. A patent is a set of exclusive rights granted by a state, national government, to the inventor for a limited period of time in exchange for a public disclosure of the invention. http://www.whatspatented.com/ http://arstechnica.com/gadgets/ Cloud-based - software systems that based on the cloud (internet) Voice recognition system- computer technology that uses audio input to enter data instead of a keyboard input. Audio input is carried through a connected microphone. The Software is designed to recognize words or phrases with an internal database. The program would then match the audio signature of speech with corresponding data in the database. http://www.wisegeek.com/what-is-voice-recognition.htm Cloud-based voice recognition - The voice recognition software the is important to virtual reality since it provides a fairly natural and intuitive way of controlling the simulation while allowing the user's hands to remain free. The audio signals are converted to electrical signals, and then transformed into coding patterns to which meanings have been assigned. Automated voicemail - Automatic voicemail system that stores voice messages. Goog-411 - an automated information service that uses voice recognition to find information for what the caller is asking for on local businesses. This also has a feature to send the information to the caller's phone via text messaging. Goog-411 has provided a foundation for Voice Search (search Google by speaking instead of typing, Voice Input (filling in any text field on Andriod by speaking), and Voice Actions (Controlling Android phones with voice commands). http://arstechnica.com/business/news/2007/04/google-rolls-out-free-411-service.ars Android - Google's mobile operating system (a modified Linux Kernal system).

drive-by downloads Drive-by downloads are downloads to the computer that are harmful, and are downloaded because the user doesn't know that the download took place, what was downloaded (virus, malware) or downloaded something, but didn't know it was malware. When a malicious website is visited, malware may be downloaded to the computer without users even knowing. Solutions to prevent drive-by downloads include having the internet security suite (like Norton Internet Security) installed and kept up to date. Also, using a proxy can filter the web content (like Vidalia). The user's antivirus firewall should always be turned on. http://www.softwarenewsdaily.com/2010/12/drive-by-downloads-malware-installed-without-your-knowledge http://www.associatedcontent.com/article/794101/how_to_prevent_driveby_downloads_.html Clickjacking Clickjacking, also known as user-interface (UI) redressing, is one of the most common attacks against users by creating malicious pages that tricking users to click on buttons and links which reveal sensitive information, or can allow the attacker to take over control of the user's computer. The true function of the button is hidden under an opaque layer that shows something different to trick the users. A possible solution to clickjacking is the "walled garden" that iPhone has. It has a closed or exclusive set of information services provided for users, instead of allowing open access to apps and content. https://www.owasp.org/index.php/Clickjacking Targeted brand attacks on social networks Targeted brand attacks on social networks is attacking the big brand names, and attacking its reputation, currently common through attacks on social networks and phishing. Scammers that hijacked a social networking account can add random people to their friends list, and link them to malicious sites. Or an attacker would disguise themselves as the "official" profile of the brand company, and make friends and trick them into revealing sen

Describe ITGS terminology and systems. Internet : a computer network consisting of a worldwide network of computer networks that use the TCP/IP network protocols to facilitate data transmission and exchange Bit.ly : URL shortening is a technique on the World Wide Web where a provider makes a web page available under a very short URL in addition to the original address. Top level domain : A top-level domain (TLD) is one of the domains at the highest level in the hierarchical Domain Name System of the Internet.The top-level domain names are installed in the root zone of the name space. For all domains in lower levels, it is the last part of the domain name, that is, the last label of a fully qualified domain name. 5. If possible, describe a solution to the concern (issue). It is hard to suggest a solution basically because it is the government's decision to shut down the internet. Therefore the only way to solve this issue is to discourage dictatorship in Libya. Main reason for the shut down of the internet was the cooperation of Libya Telecom & Technology which is owned by the dictator's son.

It creates an encrypted connection between your web server and you web browser that will protect transmitted private information from eavesdropping, data tampering, or message forgery. Man in the Middle- is the type of attack where attackers intrude into an existing connection to intercept the exchanged data and inject false information. It involves eavesdropping on a connection, intruding into a connection, intercepting messages, and selectively modifying data. DigiNotar= DigiNotar is registered by the OPTA as a CSP that delivers qualified certificates that comply with the Dutch act on electronic signatures with respect to the European directive on electronic signatures. Sinces 2004 DigiNotar has entered the PKI hierarchy of the Dutch Government: PKIoverheid. This allows DigiNotar as Certificate Services Provider (CSP) to issue certificates complying with PKIoverheid specifications to government organisations. HTTPS: Hypertext Transfer Protocol Secure (HTTPS) is a combination of the Hypertext Transfer Protocol (HTTP) with SSL/TLS protocol to provide encrypted communication and secure identification of a network web server.

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

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.

Describe VPN. A VPN means virtual private network and what it does is that it send you data over the Internet in a secure connection. It travels packet over unprotected network in a secured manner. It provides you tunnel which secures your data and send it encrypted form over the Internet. How does a proxy work? By using a proxy the web browser window is then coded as part of the proxy site address and not the real website the surfer is visiting. Any information cached in the temporary folder is that of the proxy, not the users. This means the user is not traced at all and the information is kept hidden. Article Source: http://EzineArticles.com/3786946 List a proxy you find useful. Tor Trycatchme anonsafe When would you use a proxy? When you want to hide your IP from anyone. It is a good idea to use it while online shopping, accessing bank websites, and putting personal information. Explain: Google has "played a role in manufacturing social disorder". This means that Google has been the source of creating all the social disorder in the real world. Examples of these social disorders include the Libyan Protests as well as the Egypt Protests. These are named as social disorders. And Google, who feeds information to the various organizations and governments as well as provide social networking interfaces play a role in the community to communicate with each other in order to plan these social disorder events, such as the protests to overthrow the government.

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.

Google have transfer you automatically to its "encrypted" service, one designed to prevent potential "eavesdropping" on your searches. Google have use SSL( secure socket layer) to protect your search. Is can also be use when you are logging on to your bank account online. Google have introduce the SSL search, with the SSL search you can do your searches on Google with more secure and you are in private so no one can see what are you searching. Before Google URL was HTTP/www.google.com but now it is HTTPS/www.google.com. Its secure now. Google have use SSL to help protect your data from unwanted access. So what you are connected to internet café, local hotspots or hotel your data will be secure. But Google is not responsible for any viruses you get over the internet searches. The SSL will only protect your personal information.

Wooh How might the internet be useful for the Egyptian citizens? What does it mean "bring down Egyptian websites"? Feb 4

1. How might the internet be useful for the Egyptian citizens? Egyptian citizens, especially for the protesters, have organized the initial protests against the government online, through social media such as Facebook groups. The restored Internet would allow them to use to do so again and other citizens are now back to their computers and can have regular socialization online. A main ways of communication with the outside world as well as with themselves, Internet would allow the citizens to join together through websites on the internet to create groups that support what they think is best for them. In this case, they want a reelection from their current leader. 2. What does it mean "bring down Egyptian websites"? "Bring down Egyptian websites" means to stop access to those Egyptian websites through means such as having a DoS attack on the website. Also hackers can hack into the website and destroy the coding and content of the website and thus "bring down" the websites. Bringing down Egyptian websites can also mean that they are blocking all access to Egypt because there wouldn't be any portal into Egypt if all the Egyptian websites are brought down.

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.
