Question: Discuss About The Manipulate People Confidential Information? Answer: Introduction Internet of Things refers to a system of interrelated computing devices that are connected through the internet . This is done by using sensors which enable the devices get stimulated by something in their environment or from another device. The device will then react by performing another action after the stimulus is detected or received. Literature A security breach is an incident that results in unauthorized access of data, applications, services, networks or devices by bypassing their underlying security mechanisms. This occurs when an application, individual or device accesses a confidential, private or unauthorized logical perimeter . Therefore, a security breach is like digital trespassing. For Internet of Things a security breach can be on a sensor, the network as a whole or just a device. By attacking any part of the system, one can elicit actions that are different from what should happen. There are different types of attacks that one can launch on a system. The major attacks on IoT are: Denial of service where the network is made unable to perform its usual tasks by being flooded by spam requests, social engineering which involves manipulating people to give up confidential information, data and identity theft, man-in-the-middle attack where an attacker intercepts communication between two systems and botnets which are a group of systems that are combined for remotely taking control and distributing malware . Business Case A pair of security researchers demonstrated at a Black hat hacker conference in 2015 how to hack a wirelessly connected sniper rifle from a company by the name TrackPoint. The device allowed attackers to exploit the vulnerabilities remotely or when connected to the network by logging into its network which had a default password. Once logged in, one had administrative access to the device. This could enable one to completely disable the device or even change its targets. Analysis The security breach in this case is due to the weak password set for the device. In this case a default password is used. As long as someone has that password or can guess the password and they are within the devices range they are able to control the device. To solve this issue, the company needs to create random default login details for one time use on each of the devices as they are manufactured. The credentials should then be changed by the user after they are deployed. This will make it difficult for one to guess the credentials and log into the devices API. Conclusion Security is an issue that should always be thought about since a system is never truly secure. It is always only a matter of time before a vulnerability is discovered. However, when creating or manufacturing a digital device, it is always good to test it to ensure it passes the basic and most common security tests References A.

Media & Culture - Sign Symbol A sign system is representation through communication which in turn leads to a shared meaning or understanding. We hold mental representations that classify and organise the world (whether fact or fiction), people, objects and events into meaningful categories so that we can meaningfully comprehend the world. The media use sign systems through newspapers, magazines, television,internet, and the radio etc. The conceptual map of meaning and language are the basis of representation. The conceptual map of meaning, are concepts organised, arranged and classified into complex relations to one another. The conceptual map of meaning although allows you to distinguish your own individual interpretation of the world, at the same time as holding similar views to that of other people in your culture. As the meaning is produced and constructed and in turn learned by a particular group of people. Therefore sharing conventions and codes of their language and culture. Signs can only convey meaning if we possess codes which allow us to translate our concepts into language. These codes are the result of social conventions which lead to the shared maps of meaning. These shared meanings are learnt unconsciously as we become members of a culture.If we have a concept of something in our minds we can say we know the meaning of this concept. However we cannot express or communicate this meaning without the second system of representation, language. Language is the only way in which meanings can be effectively exchanged between people, as people within the same culture are able to interpret the sign of language in the same manner. As the meanings become natural through the conditioning of culture. For example the word white in Australia represents a colour of purity, however in China it is the colour of death. Demonstrating that different cultures have not only have different meanings in their shared conceptual maps, but a different language to express it. As meanings change rapidly throughout cultures to really understand another culture you must live there and speak the language for some time. Cultural, social, political, and linguistic conventions are learned over time. The three theories of representation, reflective, intentional and constructionist approaches explain how representations through language work. The reflective approach is where language functions as a ?mirror? of the particular elements perceived meaning. The intentional approach, is where the authors individual views of the world are expressed. Whereas the constructionist approach is where we the audience construct the meaning through our shared conceptual maps and language. The media use these sign symbols so that an association can be made to the object, person, event, or idea etc. With this information of representation and language the media can familiarise people with many things, such as cultural knowledge. As advertising surrounds consumers, concern is often expressed over the impact on society, particularly on values and lifestyle. While a number of factors influence the cultural values, lifestyles, and behaviour of a society, the overwhelming amount of advertising and its prevalence in the mass media suggests that advertising plays a major role in influencing and transmitting social values. In his book Advertising and Social Change, Ronald Berman says; The Institution of the family, religion and education have grown noticeably weaker over each of the past three generations. The world itself seems to have grown more complex. In the absence of traditional authority, advertising has become a kind of social guide. It depicts us in all the myriad situations possible to a life of free choice. It provides ideas about style, morality, and behaviour. While there is general agreement that advertising is an important social influence agent, opinions as to the value of its contribution are often negative. Advertising is criticised for encouraging materialism, manipulating consumers to buy things they do not really need, perpetuating stereotyping, and controlling the media. The media must consider the cultural variables of each country, such as the complexity of learned meanings, norms, language, customs, tastes, attitudes, religion, traditions, education, lifestyle, values, and the ethical/moral standards shared by members of each society. These variables must be learnt by the media as not to offend the group they are portraying. Cultural norms and values offer direction and guidance to members of a society in all aspects of

5 Tips on Self-Publishing an Ebook 5 Tips on Self-Publishing an Ebook While weÃ¢â¬â¢re still fond of the old-fashioned papery versions, no one can deny that digital self-publishing has made it much easier for authors to find an audience for their writing. But how does self-publishing an ebook work? And what do you need to do? We have a few tips to share. A library in tablet form! 1. Edit, Edit, and Edit Some More! If you want to impress readers, typos and bad formatting have to be avoided. But many ebooks fall into this trap due to a lack of editing and proofreading. Make sure your manuscript is ready before you even think about publishing. This means seeking feedback and redrafting until it is perfect, as well as formatting it correctly. Getting the final draft proofread is essential, too, so get in touch with us when youÃ¢â¬â¢re ready! 2. Cover Art WeÃ¢â¬â¢re told not to judge a book by its cover, but not everyone listens to this advice. As such, youÃ¢â¬â¢ll want to think about how you present your ebook. Your cover art should look professional and work as a thumbnail. And remember to write a short, catchy blurb to use on the back cover. 3. Picking a Platform There are plenty of services self-published authors can use, including major industry players such as Kobo, Amazon KDP, and Smashwords. Amazon KDP also has a Ã¢â¬Å"SelectÃ¢â¬ service, which offers extra benefits in return for publishing exclusively on Kindle. This can be great for new authors, but once you are more established, you may want to publish on multiple platforms to reach as wide an audience as possible. 4. Creating an Ebook File Some self-publishing services automatically create an ebook file when you upload a Microsoft Word document. However, for extra control over the process, you may want to do this yourself! The biggest decision here is which file format to use. A PDF is fine if your ebook will be read on computers, but for mobile devices youÃ¢â¬â¢ll need a dedicated ebook format. Your options here are ePub and MOBI (Amazon KDP only accepts MOBI files, so keep this in mind if using this service). You cannot create ePub or MOBI files in MS Word, but there is software available to do this. 5. Selling Your Ebook Once your ebook file is ready, you need to find an audience and promote your book! Part of this will be done on the publishing platform (e.g., writing a blurb, picking keywords, setting a price). The rest will come once your book is available for purchase. Think about setting up a blog and social media accounts, sending a free copy to reviewers, or limited giveaway and discount promotions. The point of all this is to get people talking, as word of mouth and positive reviews will help more than anything else!

Gary S Becker's A treatise on the family Essay Example | Topics and Well Written Essays - 1250 words
Gary S Becker's A treatise on the family - Essay Example As such, the purpose of this brief analysis is to review and comment on some of the key themes and ideas that have been put forward by Becker and seek how they maintain a relevant and pertinent quality within the current economic system. Furthermore, the basic premise put forward by the author with relation to the fact that the family represents a microcosm of the larger national and international economies will be further analyzed. Regardless of oneÃ¢â¬â¢s political persuasion, it is without doubt that the family is one of the primary social constructs upon which society is based. Without families (either as an abstract concept or a more traditional one) society itself could not and would not perpetuate itself. As such, understanding the unique dynamics with relation to these most basic and integral building blocks of our world is one of primal importance. Within this vein, the author goes on to describe key elements of social and economic interactions, both within and without of the family. These include the discussions relating to single person households, sexual division of labor, need/demand for children, intergenerational mobility, and the general trends that have been developing over the past few years with relation to the evolution of the family. A full analysis of each theme that Becker has brought to attention with regards to the economic effect on the family unit and the economy as a whole would require a much larger work than such a brief paper can offer. It is necessary to point out the unique way in which the author demonstrates the aforementioned points that help to nuance and develop the way individual economies and macro economies behave. What is interesting and laudable about BeckerÃ¢â¬â¢s analysis is that he begins it with what many would consider to be the weakest link in his analysis: single person households. In this way, rather than seeking to
