Why did Egypt block the internet? To shut down communications within the people of Egypt to stop them from organizing protests against the government using social networks as a tool of communication. How has the internet supported civil disobedience? Many of the protests were organised with the use of social networks such as Facebook and Twitter, which helped everyone to organise the protest with people they didn't know. What does it mean when the US says social media is a fundamental right? US is saying that social media is a fundamental right, therefore should not be blocked or shut down, because it has become an important source of communication, and people have the right to know what's going on in the world.

How was the attack done? How did they know an attack happened? Why is this an important issue? Describe a possible solution. all nov 23 Chut

How was the attack done? The hackers were able to obtain credentials from a company that makes software used to control the industrial systems. How did they know an attack happened? They knew that there was an attack because one of the pumps that is used to deliver water to the city was turned off. Why is this an important issue? This is an important issue because it indicates the amount of attention the United States government is giving to cyber-attacks. A terrorist attack like the one happened on September 9th 2001 can be said to be the faults of those who were monitoring the cyber activity. If the government aren't able to connect the dots to why they are doing this and the patterns of the attacks it might cause the US to be under attack like what happened over ten years ago. Describe a possible solution. Since that the credential software are saved on the clients' server, the employees can do a part in protecting the software. The staffs can help support the software.

Sue Describe BGP. How does the BGP affect ISPs? Feb 4

 Describe BGP - BGP is the border gateway protocol, the protocol at the core of the internet's routing mechanism. BGP performs interdomain routing in Transmission-Control Protocol/Internet Protocol (TCP/IP) networks. BGP is an exterior gateway protocol (EGP), which means that it performs routing between multiple autonomous systems or domains and exchanges routing and reachability information with other BGP systems. - Control the pathways  How does the BGP affect ISPs? - BGP glues all ISPs and their large customers together to form the Internet. Besides traditional routing, BGP also supports routing for new IP services such as Multiprotocol Label Switching Virtual Private Network (MPLS VPN). - Without BGP information provided by Egyptian networks, the rest of the world has no way to connect with the country's ISPs or its Web sites. Nor do its citizens have a way to reach sites or services beyond its boundaries. - "The Egyptian government has instructed the ISPs whether state owned or sate licensed, to withdraw their BGP announcements that tell other routers how to reach those ISPs" -

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.

Identify the area of impact the scenario relates to. Business Identify the main stakeholders to the IT system. Sony, Geohot, users of PS3, users of Geohot, twitter, youtube, Google 3. Identify one ITGS social/ethical concern in the article. Privacy and anonymity 4. Describe ITGS terminology and systems. IP address : An Internet Protocol address (IP address) is usually a numerical label assigned to each device (e.g., computer, printer) participating in a computer network that uses the Internet protocol for communication. An IP address serves two principal functions: host or network interface identification and location addressing. Sources : http://en.wikipedia.org/wiki/IP_address iOS : iOS is Apple's mobile operating system. It was originally developed for the iPhone, and it has extended to support other Apple devices such as the iPod touch, iPad and Apple TV. Geohot : George Hotz, known for working with other people to unlock the iPhone, allowing the phone to be used with other wireless carriers. 5. If possible, describe a solution to the concern (issue). There is no possible solution because even if Sony gets hold of all IP addresses, there will be alternate ways for users to still access GeoHot's websites and videos. Moreover, the US justice system shouldn't give rights to companies to access personal information, because it is basically invading peoples' privacy.

What does cloud computing deal with? Describe each of the characteristics cloud services must have. Explain horizontal and vertical services. Define each layer of services. Explain the infrastructure capability terms. Why is bandwidth important? march 17 cream

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.
