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" -

What were the chinks in the blackout? What are problems with cutting national and international cables? Explain the possible financial impact of blackouts. How can a blackout backfire? march 11 kuni

What were the chinks in the blackout? Many people abroad offered the Egyptians internet though the terrestrial phone system, which was basically a dial-up system. Moreover, Google and Twitter launched a service where users can voicemail their tweets, which is then converted into text, to publish their tweets online. What are problems with cutting national and international cables? It will cost a lot in budget and maybe some damage too, because it is complex and expensive to build and run a kill switch. Explain the possible financial impact of blackouts. The financial, impacts the finance of the blackouts are that money transactions and deposits are affected by the suddenly cut line, which may cause problems to both local individuals as well as large companies that are trying to seal a business deal between each other. An intergovernmental think-tank in paris predicts that the cost of damage in Egypt for its network shutdowns was around $90million. Also, other international countries that are trying to invest in the country that has a blackout are most likely to rethink their decision, and take their investing plans to another more stable country. This affects the country as the whole since they will be losing investors in their country. This would also affect the economy as rates change, the amount of people (tourists) flowing in and out of the country including business groups. How can a blackout backfire? A blackout can backfire its government because it can cause the citizens to view the government's act in a bad way. Cutting of connections will people will stop trusting its government, and would want to overthrow their leader/government. Moreover, This is somewhat a loss for the government. They wouldn't want their citizens to go up against them. Thus, citizens play a major role on how a blackout can backfire. The cutting internet doesn't help at all.

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.

The Data Breach in this article refers to their security system data being violated by an outside offender, such as it being stolen or copied when it's not supposed to be. The advanced cryptographic system is the security system that has an extra layer of security by an electronic token authenticator that generates a time-based number for the users to input while logging in with their password. It is suspected that the master key for the encryption algorithm was stolen, which is the huge secret number that is part of the system. 4. Describe ITGS terminology and systems. SecurID- a mechanism developed by RSA Security for performing two-factor authentication for a user to a network resource 5. If possible, describe a solution to the concern (issue). The solution for this issue is to update the security system often and try to get against from hackers. Having SecurID make up a new algorithm to be used for the system could reinforce the system's security again, if it's possible to make up a new algorithm. Other than that, SecurID would probably have to make up a whole new security system since their current stolen algorithm is probably going to be published and recopied, and the system not secure anymore.

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.

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.

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

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

manned aircraft couldn't provide. Also, UAS could be used to fly in to observe or take samples after a chemical or biological attack. Any missions too dangerous for manned aircraft will be taken care of by the UAV. UAV have other advantages over manned aircraft as they have more detailed information about their targets, their strikes are more accurate and cause fewer civilian casualties. They are also cheaper and smaller. Since they have no pilot, the space could be used for fuel and thus they can fly much longer than manned aircraft. Without the need to accommodate crew, drone can be given radar-cheating stealthy shapes and can maneuver better. There are however a problem afflicting the drones as they depend on two-way satellite communications. If the datalink is broken the remote pilot will lose control of the aircraft. For missions requiring constant oversight, the vulnerability to electronic jamming or a direct attack on a communications satellite is a huge problem. Another problem is that the dones has a slight delay between the remote pilot and the aircraft. To reduce latency, small, solar, or laser powered ultra long endurance drones can form a chain in the sky along which satellite signals can be bounced. To reduce the workload on pilots, big UAV can take off and land automatically. The US Air Force plans to have a pilot operating up to four drones at a time. Civil liberty advocacy groups have raised concerns about targeted killings by drones. Bus as long as a UAS pilot can trust data from remote sensors, he or she should be able to make a proper assessment the same ways as the pilot of a manned aircraft. UAS pilot will be in a better position to do so since he or she will have more time to assess the situation accurately and not be exhausted b the physical battering of flying a jet.

Allowing the UAV to fire a weapon based entirely on its own data analysis raises a lot of ethical problems. Using UAV to kill enemies thousands of miles away is like a cowardly action of a bully sheltering behind superior technology. There are fears that UAS will lower the political threshold for fighting and an essential of restraint will be removed. Drones make leaders fonder of war.

Explain why becoming a data consultant might be a good career choice. Basically, their jobs are to help businesses make sense of an explosion of data Web traffic and social network comments as well as software and sensors that monitor shipments, suppliers and customers. So, since a great number of people have used the Internet frequently, their jobs are needed to people because as much as people use the Internet, the data will be increased and people need other people who can manage such things. Why is data measurement considered to be the modern equivalent of the microscope? The reason is that there is countless data sensor around the world. The sensors can measure and communicate location, movement, vibration, temperature, humidity, even chemical changes in the air. How has data-driven decision making improved productivity? Data-driven decision making has improved productivity because people collect as much as data they can before deciding. As people doing that, they can predict preference of consumers from the Internet. It is very useful because people don't have to spend much time on consumers' preference also, a small amount of money and time will be spent. How is Big Data transforming the way social networks function? Social networks websites such as Facebook and Twitter and Search engines like Google and Answer.com make profit with their users' data. Many companies will buy the users' data from Facebook, Google, Answer.com and Twitter. That's a way to earn money for social network websites.

Explain the issue with Path. When you take apps by log in from your iOS device then it would take you personal information and put it into the Apple server. It does this without permission of the user. The reason why is doing this to locate the user where you are at and your friends. Evaluate Apple's solution. Their solution is just to add new feature so you would be aware that apps would take your private information and put into the main server apple server. When you're downloading or getting apps you need to approve that they get you privacy information. Should services such as Path take or hold our data? I believe that they shouldn't because it's hard to trust large companies. The information that they have could be sold to other person that interest about your privacy. Another possible solution is that the data that is stored could be hacked anytime and when this occurrence happens. The hacker can sell my privacy to someone or he directly knows where I live, what's my name and etc.
