    Google has enabled encrypted searching using SSL (Secure Sockets Layer) which it says will prevent "employers and internet service providers" from reading what is sent. The possibility that employers and ISPs might be watching peoples' search traffic clearly concerns Google, and it has often concerned employees.

    Might want to rethink those tags Sr Pastiche. Any suggestions anyone?

    Essentially what Google is trying to do is to offer people a way of securely navigating their website, using SSL, so that people don't have to worry about being monitored. People can see if they are using the secure version of the google search engine if the web adress cointains "https" rather than just "http". SSL works as follows: 1- The web browser being used checks the websites' certificate to make sure that the client is connecting to the real site and not someone intercepting 2- The encryption types that the browser and the web site server can both use to understand each other are determined 3- Browser and Server each send each other unique codes to use when encrypting the data that will be sent 4- The browser and server start communicating using encryption, leaving the web pages secured. For more information on how SSL works ckeck the following website: http://www.ourshop.com/resources/ssl.html

    The following article shows how the asymmetric encryption inherent to SSL (Secure sockets layer) and TLS (Transport Layer Security) have been rendered useless by a tool called BEAST (Browser Exploit Against SSL/TLS). It attacks the "AES encryption algorithm" used in the cryptographic protocols. "BEAST is able to grab and decrypt HTTPS cookies once installed on an end user's browser." "While other attacks focus on the authenticity property of SSL, BEAST attacks the confidentiality of the protocol. As far as we know, BEAST implements the first attack that actually decrypts HTTPS requests". "Transaction confidentiality based on the SSL TLS V1.0 protocol (the most used still today) is dead." "The only true defense from fraudulent transactions is to sign the (...) transaction data so that the attacker cannot inject bogus material. This means effectively using a token with a pin pad." "Fixing the vulnerability that BEAST exploits may require a major change to the protocol itself." http://www.itpro.co.uk/636304/ssl-under-threat-as-flaw-exploited

    When you turn on your computer, it's nice to think that you're in control. There's the trusty computer mouse, which you can move anywhere on the screen, summoning up your music library or Internet browser at the slightest whim.

    In my opinion, the main objective is purely to protect the entertainment industry by blocking infringing domain names however, as stated in the video these industries do not contribute so much to the US economy. Furthermore, theses bills will put the stability of new search engines at risk as the US government will be able to sue them if they advertise any infringing website.

    If you're looking to understand the debate from the perspective of copyright holders, then watch Follow the Money: Who Profits from Piracy?,( http://vimeo.com/22541902 ) a video that tracks the theft of one movie, making it a microcosm of a larger problem.

    Although protecting the entertainment industry from piracy and blocking certain websites containing disturbing and innappropriate material (paedophilia) is a good idea, the way SOPA and PIPA have been written/proposed makes it very easy for people enforcing both acts to abuse their power. Once we censor one thing, other will decide that other things must also be censored, therefore destroying any sembelence of free-speech Internet users have. I also find it worrying how the American Senate decided by itself that these two acts should be made law, in the process crippling the Internet, a resource used by billions of people all around the world and not just the population of the US.

    Criterion B . Describe, step by step, how the IT system works. How unauthorised sites outside usa jurisdiction is censored within american borders: A little bit like the great firewall of China, this kind of censorship takes place at a router level. 1. The American ISPs enter the domain names of the unauthorised sites and directories, blogs and forums that contain related links into the Internet routers. These enable data to flow back and forth between ISPs in the USA and Internet servers around the world. 2. The user types in the domain name of an unauthorised website. 3. The request is sent to the web server at the ISP, and the domain name is looked up on the database of addresses in the router 4. The router denies the request from the web server 5. An error message appears in the user's browser how chinese censorship works - http://embargo.gn.apc.org/3.htm#_ftn5 how internet works - http://www.explainthatstuff.com/internet.html

    The SOPA is mainly adresses the protection of intellectual property of content creators. Obviously this is the one of the biggest advantages being proposed by the act as artists and entertainers will be able to profit more from the content they make. Nowadays much of their content is illegally downloaded from the internet, such as music. However SOPA will have a severe impact on online freedom of speech as numerous websites would be affected by the act and blacklisted as a result. The internet is makes frequent use of copyrighted material not necessarily in a legal way. Doing streaming of such content after the act could lead to a maximum penalty of five years in prison. However the US congress states that protecting intellectual property is not the same as censorship http://agbeat.wpengine.netdna-cdn.com/wp-content/uploads/2011/12/sopa-infographic1.png The image above provides more detail about SOPA including how it will take effect and the impact it would have on businesses. It shows the major supporters of SOPA as well as the major opposers, one of them being Google.

    Apparently there are multiple ways of circumventing the SOPA: 1. Using a VPN Service 2. Using Your HOSTs File 3. Using TOR 4. Using a Web DNS Tool 5. Changing Your DNS Server 6. Using Command Prompt 7. Using Foxy Proxy 8. Using MAFIAAFire Source: http://www.zeropaid.com/news/95013/8-technical-methods-that-make-the-protect-ip-act-useless/

    An Israeli hacker has published details of hundreds of Saudi credit cards online and is threatening to post more in revenge for acts by Arab hackers.

    One of the main social and ethical issues in this article is surly privacy. Privacy has been a main issue for our society, not only about credit card details, yet also other personal information. As technology is increasing, the less privacy we have as there are more ways in obtaining this information. And in this case, as technology is increasing, hackers are also as there are easier and more ways in order to get the information they want. There are various ways the hacker can get access to these thousands of credit card numbers, here is one step-by-step of one of the ways of how this IT system works: Firstly, the hacker (or hackers) go around lots of banks and put a small video camera pointing to the bank machine keypad. This video camera is well hidden so that people cannot see them. When someone goes to the machine, they put their credit card number and this analogue information converts to digital information and is recorded in the memory in the video camera. After a few hours/days, the hackers remove the video cameras and upload the data in the memory card via a USB cable and save the data on their servers. The hackers then watch the video and record the credit card numbers on a paper/other computer. With this information, they can obtain more personal information such as names, phone numbers, post codes etc with specialized programs. Finally, when they have all the information they have, they post the personal information including the credit card numbers, on the internet. Yet, in order to maintain the hacker anonymous and not being able to be found via the IP address, he uses another proxy server when uploading this information on the internet. There are also other ways to get the credit card information such as: - Intercepting emails containing passwords - Popups infected by viruses - Spyware - Spam - Keyloggers etc. Some possible solutions for this issue is: - When typing your credit card number in the bank machine keypad, hide the keypad coveri

    Well yes, I agree with Ines. This is to some extent about privacy. However, I doubt that they obtained that much information by use of cameras in banks. I'd find it much more likely if they have obtained the data from a database in the private sector. I do not think privacy is the most important issue here though. By far and large the most important issue in the article - is how cyber warfare could start to affect the conflict in the Middle East. We've seen how valuable the Internet was in the Arab Spring. The cyber warfare is going to be, and to some extent I imagine, is already an essential tool for the different factions in the Middle East. As this was a breach in the private sector, the security there must be improved with f.ex. stronger firewalls.They must improve their security, if not they are sure to lose money because of the reliability issue.
  • Ines Simon on 19 Jan 12
     
    I agree with you, Morten. However, I gave one example of how it would be possible to obtain the credit card numbers, where I gave in the end more examples of how it would be possible to do so.
