Jean October 10th  Describe the IT system by watching the video Answer here

Basically just watch the video... ok lets start 1. The apps used in the supermarket needs to be downloaded by the clients before use. 2. Enter the store and open your apps from your mobile. 3. Pick the goods you want and scan the code off the bar code (using your cell phone) 4. The list of goods you buy will be store into your cell phone. 5. After scanning click the finish shopping button on your apps and the cell phone will generate a big bar-code which mix all the code you scan into one master-code. (like mixing salad after you put vegetables in) 6. Go to the paying counter and insert the master-code into the paying machine. 7. The machine will tell you how much to pay and client pay by cash, credit card and etc, Extra ( you can play stepping on fish in the supermarket for fun) Oh and there is a useless robot roaming around also.

1. Identify the area of impact the scenario relates to. The area of impact the scenario relates to is 'business and employment'. 2. Identify the main stakeholders to the IT system. The main stakeholders to the IT system from this article are the RBA (Reserve Bank of Australia) and customers. 3. Identify and describe one ITGS social/ethical concern in the article. The social/ethical concern that has been identified in this article is 'security'. Security refers to the protection of hardware, software from unauthorized access. Security tries to prevent the access by hackers. In this article, the RBA has been hacked (cyber attacked). For an example, the malware has embedded in the emails. They think it is China to blame because they thought that China has already been through a similar cyber attack, which aimed to get the information out of it. The staffs in the RBA have opened several malware emails. This malware application has managed to go through the computer system. 4. Describe ITGS terminology and systems. * Malware: Malware refers to software programs that are designed to damage or do other unwanted actions on a computer system. * Cyber Attack: Cyber attackers use malicious code to alter computer code,logic or data, resulting in disruptive consequences that can compromise data and lead to cyber-crimes (information and identity theft). * Computer Viruses: Small but insidious piece of programming-code that attacks computer and network systems through infected data files, introduced into a system via disks or Internet. 5. Describe the solution stated in the article or find a solution to the concern (issue) discussed in the article. Even though the RBA did not lose any of their information, it's better to have a safe security system/software to protect their information. The RBA needs to be more careful when opening email files, and for a better protection, they would need to find a better way to secure. I would suggest them to have an encryp

Da Woon November 1st  Describe the IT system

This article tells us the air traffic controller (ATC) which helps us to have safe fly. ATC has access to sophisticated radar systems that provide an overview of the airspace they control, and they have communication tools to coordinate flight paths with the air crew. When the aircraft travel at higher speed than common modes of transport, the time available for pilots to react to a dangerous situation can be quite short. And ATC helps to aircraft approaching an airfield carefully and it checks the weather conditions for prevent pilots can't see other aircraft. ATC uses radar systems positioned at ATC facility to get a real time overview of the aircraft flying in the airspace they control. Many types of radar equipment are served for traffic on the ground. Primary Surveillance Radars (PSR) - The radar sends a directed pulse into the atmosphere, and when that pulse encounters an object it gets reflected back to the radar station. The bearing of the object with respect to the radar station and its approximate distance can be calculated by this. The radar is typically enclosed in a dome to protect it from adverse weather. Secondary Surveillance Radars (SSR) - the Secondary Surveillance Radar listens for messages from the aircraft's transponder. The radar rotates about the vertical axis, but transmits a specific signal on 1030 MHz. This signal is subsequently received by the aircraft's onboard transponder, which responds with a reply on 1090 MHz. SSR Modes - There are different modes of interrogation that compliant transponders respond to. A - The transponder responds with its squawk code, a unique identifier for the aircraft assigned by ATC comprising of four octal numbers. This code enables ATC to differentiate between the various aircraft being monitored, though it can also be used to discretely communicate the existence of an emergency situation onboard the aircraft. C - the transponder responds with the aircraft's pressure altitude, which is the altitude ab

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

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

Authentication- Authentication is the process of determining whether someone or something is, in fact, who or what it is declared to be. In private and public computer networks (including the Internet), authentication is commonly done through the use of logon passwords. Knowledge of the password is assumed to guarantee that the user is authentic. Each user registers initially (or is registered by someone else), using an assigned or self-declared password. Tokens- A Hardware Token is an Authenticator in the form of a physical object, where the user's interaction with a login system proves that the user physically possesses the object. Hardware Tokens authenticate users on the basis that only the Token assigned to the user could have generated the pseudo-random number or code response keyed in by the user. Successful entry of this code implies that the user is in physical possession of the Token. This implies that the user does not allow users to use his Token, and has not lost it. It is use to prove one's identity electronically, and it is small enough to put it in the pocket or attach to keychain. Smart Card-A card with an embedded computer chip on which information can be stored and processed. It is a plastic card about the size of a credit card, with an embedded microchip that can be loaded with data, used for telephone calling, electronic cash payments, and other applications, and then periodically refreshed for additional use. Biometric- Biometrics is the science and technology of measuring and analyzing biological data. In information technology, biometrics refers to technologies that measure and analyze human body characteristics, such as fingerprints, eye retinas and irises, voice patterns, facial patterns and hand measurements, for authentication purposes.

The Piracy Problem: How Broad? Why are copyright violations are a serious problem? Copyright violations are a serious problem because it is equivalent to stealing. A person who watches from free online movies doesn't realize that all the people behind the movie used their time, labor and energy to create that movie, not to mention the amount of money that was used to produce the movie. So, to broadcast it to as free movie is truly unfair for all the industries concerned. Describe two advantages and two issues with illegitimate downloading. Advantages: (1) People around the world who can't afford to have it have the option of having for free. (2) It is available anytime, anywhere in the world. Issues: (1) Million of dollars as revenues and earnings are stolen from industries (movie, music, TV, etc.). (2) It will cause the affected industries to increase the price of their "product" when purchasing it legitimately. Explain two possible solutions to this kind of piracy. Possible solutions: (1) If people around the world really see stealing as a morally corrupt practice, then let us all shun away from the use of the internet. (2) If we can't afford to avoid the disadvantages of the Internet, let us all practice, encourage and teach honesty. This golden virtue is the only potent cure against SOPA and PIPA. Not enough is being done to tackle cyberbullying, according to the NSPCC. Give examples of cyberbullying. Some examples of cyberbullying are the following: receiving nasty text messages or e-emails 24/7. Describe possible solutions. Some possible solutions are the following: students must not give their mobile number to acquaintances or other students who are their close friends; never chat to anyone whom you don't know; when you received nasty text messages from your mobile phone, change your mobile phone number right away; and lastly be very selective in choosing whom to friend in FB or in other social networks.

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.

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.

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
