Sony suffers second major user data theft | Reuters - 1 views

  •  
    Explain what happened. Describe the issues. May 9 jen
  •  
    1.Explain what happened. Sony suffered a hack on their PC games network, which lead to theft of online user's data from its PlayStation video game network. The theft involved 77 million user information. Sony is now hiring various outside firms to investigate on the matter, and try to find the offenders to this hacking. Cyber-security detectives from Guidance Software and consultants from Robert Half International Inc's subsidiary Protviti were brought in to help with the clean-up. 2.Describe the issues. Issues from this includes the reliability and integrity, as well as the security of Sony's protection system and online user's sensitive information which include credit card numbers as well as passwords. The reliability is the reliability of Sony's software. It might have failed to function properly, thus being a loop hole of the hackers to get through. The integrity is keep users' data complete and unaltered without their permission by the hackers. There is also a privacy issue because user's sensitive data was stolen.

    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

How Do Search Engines Rank Websites? - 4 views

  •  
    Describe the major areas of search engine optimization. m12 nov 10 alec
  •  
    1. Building Quality Back Links to Your Website - the way to a better ranking is to have quality websites link to yours. Such as websites in you niche or social media websites. If your site has these types of links search engines are more likely to give you website a higher ranking. 2. Anchor Text in Back Links - using anchor text also gets you a higher ranking, for example: if you use the URL www.sourcelinemedia.com - then the search engine only sees the site domain as part of its rankings. If you use anchor text such as Website Marketing and Design then search engines will rank you higher for anyone that searches for website marketing or website design. 3. On Page Optimization - Using key words helps to optimize your websites hits during a search. For example a site that has many key words relating to the information in its articles is more likely to get a hit on a search because the words relate to what they are searching. For example if you search Social Networking sites like Facebook, Twitter, and Tumblr would come up as the top few hits.

How Does Google Rank Websites? - 14 views

  •  
    Explain how Google's algorithm works. Why is it hard to rank high? all nov 9 johny
  •  
    The Google algorithm is also called as page ranking. Page Rank depends on the outstandingly democratic nature of the web via to enormous link structure as the sign of the values for each individual page. Google would understand a page A to page B as vote; it would look noticeably more at links age receiver and the sheer volume of votes. It would analyze what you are searching for and it would pick pages the most important page from the rest of the file that is relevant to your topic. Sometimes important pages wont answer you question. That's why Google page rank is combined with complicated text matching techniques to find the page that is important and similar to your question. Google does more then searching pages that has a match to your question it would examine the feature of the page content (satisfied) and that it would decide that is this page is a good match of your question. Because many websites don't have the possibilities to get highly ranked, because they also need to compete with other websites that comes from the company and they got millions of back links. For example you want to make a website about selling second hand stuff. When your going to try to search about second hand stuff it would directly show you E-Bay because it more popular and it has more views. The websites that you may been searching for must be on the 15 page or more then that because the web may have not enough back links or even none.

    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.

IPhone Users in South Korea Sue Apple for Collecting Data Without Consent - Bloomberg - 3 views

  •  
    Brief Aug 24 Az
  •  
    1. Identify the area of impact the scenario relates to. Business, Government 2. Identify the main stakeholders to the IT system. Apple, Google, iOS device users 3. Identify one ITGS social/ethical concern in the article. Privacy, Anonymity 4. Describe ITGS terminology and systems. iPhone smartphone - Apple's iPhone smartphone that includes various smart features such as receiving e-mail, and application, more than just the average phone. Location recognition - the feature on the iPhone that allows the users to be recognized by their location near wifi hubs. Apple was ordered to encrypt location data of people using iPhones to address privacy concerns but the users claim that the device secretly collected information of the users' whereabouts. 5. If possible, describe a solution to the concern (issue). A solution to the privacy issue would be for users to turn off the location-recognition features on their iPhones so that Apple doesn't have access to your phone. Apple needs to be more careful with their data collection process, as well as encrypting the data so there is no breach of privacy of its users, or completely get rid of the whole system itself.

Crime Map Beta - Trulia - 9 views

  •  
    What is the value of this? all sept 29 Jang
  •  
    The crime map is a site that shows the amount of crimes committed in an area. The map gives specific information about what kind crime was committed, the location and time of the crime. The site also gives data of places that crimes do not happen frequently. This crime map website can be really useful for avoiding crime scenes and being aware of crimes that are happening in your neighborhood. If you want to move to a new place you can look at the crime map to see if your new neighborhood is safe and crime free. This site is still on beta and only have information on few states in America. I think a lot of people would use this site if it have data for all the countries in the world. However keeping up with new information everyday would be very hard because there are so many crimes happening all over the world and the site would need to be updated every few minutes.

    1. Identify the area of impact the scenario relates to. Security 2. Identify the main stakeholders to the IT system. The hacking group which is called 'Turkguvenligi' and seven victims (Sites) 3. Identify one ITGS social/ethical concern in the article. Privacy and anonymity 4. Describe ITGS terminology and systems. URL- A URL is an address that shows where a particular page can be found on the World Wide Web. URL is an abbreviation for `Uniform Resource Locator'. Meaning, it is an address to access to web. DNS- DNS stands for Domain name system. It is a network service that is converting or interpreting domain or host name to IP address. In this case, it is easy to convert domain to IP address so, hackers could easily access to the webs. NBT- It stands for NetBIOS over TCP and IP. It is kind of rule for communicating that exists to run NetBIOS application in TCP and IP. NetBIOS application is an application or program interface that has been used in PC-LAN. TCP stands for transmission control protocol. It is a core protocol of the Internet Protocol Suite. SQL injection- It is a basic skill to hack information. Its ways to do is too easy so, most web sites are blocked for this. Hackers put special elements such as ' or ] between ID and password to call server to DB. They changed SQL sequence. Suppose, SELECT count(user_id) from USER_TB where user_id='test' and pw='1234' (Example) That sequence allows to login, and people can login if the result is over than 1. So, we put ' 'or 1=1 ' the space between ID and password and change it through injection attack. 5. If possible, describe a solution to the concern (issue). Since the seven web sites are hacked behind the scenes, security has to be reinforced than before. Also, they need to update the web site to check any 'debris' from attack. Although it has been announced that there are no lost, they might not confirmed for certain so, users better make sure the information is fine a

    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

Bangkok Post : Patient data need protection - 2 views

  •  
    Explain the issues and possible solutions. april 4 kuni
  •  
    The issue is that the increasing integration of medical devices in hospital networks can increases the risk of being attacked easily, which they hack into the network and steals information. They need to strengthen the security to get against with the possibility of virus attacks which could have a huge damage on delivering data for medication. The Public Health Ministry can play an important role as a regulator in healthcare security, as a same system with the security in the network banking.

    1. Identify the area of impact the scenario relates to. Business and Employment 2. Identify the main stakeholders to the IT system. Amazon and companies using Amazon's cloud service 3. Identify one ITGS social/ethical concern in the article Reliability 4. Describe ITGS terminology and systems. 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.

Learning The Right Lessons From The Amazon Outage - 5 views

  •  
    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
