Part B:
Use the Toulmin's Model of Argument to analyse the supplied Assignment Case Study (see the Assignment Case Study section below) and provide your opinion on the strength or weakness of the argument with relation to the Claim that we have provided.

You MUST answer the following 7 questions separately to complete the 'Your Opinion' section of Part B. make sure to number your answers:
To apply the model to test the validity/strength of a CLAIM the reader must examine each sentence in the article and categorise them as a Toulmin element or as an unnecessary extra

e.g. 'opinion', 'hearsay', 'definitions' etc. Once all sentences have been categorised then the elements should be examined in sequence.

1. What is the CLAIM?

2. Is there any EVIDENCE to support the CLAIM? If so how much and how does it affect the strength of the CLAIM.

3. Is there a WARRANT (Explicit or Implicit)? Explicit WARRANTS are often stronger because the author can direct the reader to accept the CLAIM. Implicit WARRANTS leave the reader's opinion open to interpretation and this may go against the author's intended purpose.

4. Is there BACKING? If so how much? If so how much and how does it affect the strength of the CLAIM.

5. Is there a REBUTTAL? The quantity and scope of the REBUTTAL may reduce the strength of the CLAIM and thus dissuade the reader's acceptance of the CLAIM.

6. Is there a QUALIFIER? If so, to what extent does it reduce the scope of the CLAIM because this will impact on the strength of the CLAIM?

7. Your Opinion - this is a personal perception based on your interpretation of the article. The presence, quality and quantity of the different Toulmin elements must be applied to make this critical assessment. You must discuss whether you agree or disagree with the claim based on the stronger argument.

Case Study: This case study must be used for Part B

Claim: Twitter puts users' privacy at risk

A piece of malicious code called Stormer has stolen 28,000 login credentials from Twitter.com, security experts have warned. Alarmist's investigators said, "It appears the attackers used Stormer and we suspect the people behind the attack are using the stolen information to login to victims' Twitter.com accounts and transmit malicious code to their associates, thereby increasing the malware's spread even further." When asked about the attack Twitter explained security experts had investigated the affected Tweeters, and said the majority of them were not active, but initiated remedial steps for all affected users to ensure the security of their accounts. Twitter public relations department was quick to note that they had not experienced a breach to this level before and would be sure to prevent it in the future.

Social networking Apps are a target of hackers because of the large amount of personal information presented on them. "It won't necessarily be obvious that you have been attacked. The malware is stealing passwords so it is not going to announce itself," said Jacob Singh, senior security consultant at Symantec. John Smith a frequent Tweeter said he felt violated but didn't know if he had been affected. Following the attack Kim K. reality show celebrity tweeted "#backoffstormer".

Alarmist CEO noted "It appears the more capable hackers are now experimenting with more sophisticated malware so as fast as the companies create a defence the attackers find a way to infiltrate it" Soon after the attack Twitter's security team released a public announcement warning Tweeters that they were just as responsible for their security and should follow simple security rules like not using passwords for multiple accounts. In 2015 a Symantec report estimated that various forms of Stormer accounted for 26.8% of all new malicious software infections.

Twitter recently updated their password creation capabilities to force users into creating stronger passwords. Twitter also stated so far, Stormer has not been spreading on Twitter itself, but they are working with their external partners to prevent further spread. Twitter CEO commented "Better educating our users will add to our defences but we can't control everything they do and they are a weak point."
