Essay on Ethical Issues in Secured Communications

“Networks are all around us. They are in our walls, in the air. At schools, hotels, hospitals, even coffee shops. Always there, always on…This power exists today. In our routers. In our switches... . (Cisco, n.d.)

Privacy and safety of citizens is common in today's society, as well as the government looking over their shoulder at all times. As an example, George Orwell wrote a book called, "1984" which in it gave an outlook of society being taken over by a party. Government surveillance is different from protecting and bringing safety to the citizens, it violates their freedom, privacy, and human rights.

In today’s world, Privacy and Security comes hand in hand with internet. Technology allows us free speech and freedom of information over the internet, by imposing strict laws and policies regulating the privacy and security of our information. According to Richard Clarke, free expression over the internet and its privacy are two sides of the same coin (Privacy and security(n.d.)). Writing blogs, uploading posts, comments or pictures on Facebook, Twitter, Instagram, networking or sharing links on Linkedin are all considered as our free expression and its security is our right. Individual right to

In both X-rays and CT scans, a form of radiation is emitted and travels through the body, and a detector receives the unabsorbed rays and transmits them to a computer. The physics behind PET scanning is quite different. Basically, a person is injected with a radioactive substance. This substance begins the process of

*TFT (thyroid function tests) – there are several diff. types of hormones so multiple test may be performed, Thyroid scans (radioscan or Scintiscan) – the pt will ingests radioactive iodine then an x-ray study performed to test thyroid

When a fellow general received the message, he would wrap the paper around his corresponding scytale to decipher the message (Tyson 2014). Since the advent of computers though, encryption has become increasing important and relies almost solely on cryptographic means to secure information. When speaking about encryption today, it refers more to the process rather than the mathematical formulas used to scramble data. The basic idea behind encrypting a computer message is such that it is scrambled with a sequence of random bits, known as a key, and only parties with the corresponding key can transpose it back into a comprehensible format. These keys are created via a cipher, otherwise known as an algorithm. When a user sends a message, known as the plaintext, across a network, the computer applies an algorithm to the information to encode it, resulting in a ciphertext (Encryption Basics 2014). This method can be best summarized visually:

Security and privacy, distinctive subjects of priority in a human being life. Privacy, the all-time, basic and fundamental ability of being free of public attention; the reason of the existence and

Type of operations used for transforming plaintext to cipher text. All encryption algorithms are based on two general principles. Those are substitution, in which each element in the plain text is mapped into another element and transposition in which elements in the plaintext are rearranged. The fundamental requirement is that no information be lost. Most systems referred to as product systems, involved multiple stages of substitution and transposition [2].

The sharing of information may well be the most advanced activity of the twenty-first century occurring across ages and backgrounds with relative ease. Nevertheless, the use of information that is aired through the internet raises several genuine concerns regarding nature, intent, source, and destination as well as the consequences of the content. This is particularly true when the information has to do with people 's identities and other activities that may touch on critical aspects of national security and unauthorized business. As such, there is a mix of reactions among individuals regarding the extent of privacy they would like regarding information that they share or retrieve on the internet. While some may have genuine concerns such as protecting their identity, others are on malicious tracks to cover their person and conduct unwarranted business on the web. The mix of concerns led to the rise of the Dark Web on darknets. A darknet is an overlay network that utilizes the public Internet but requires authorization or special software to access mainly to protect the user’s identity and location from network surveillance and traffic analysis (Sui, Caverlee & Rudesill 2003). Such trends on the internet raise the question; is the Dark Web an important and necessary tool to offset pervasive online surveillance in contemporary society or is the moral panic surrounding the Dark Web in global news media justified? The aim of this research is to answer the raised question

Ever since day one, people have been developing and creating all sorts of new methods and machines to help better everyday life in one way or another. Who can forget the invention of the ever-wondrous telephone? And we can’t forget how innovative and life-changing computers have been. However, while all machines have their positive uses, there can also be many negatives depending on how one uses said machines, wiretapping in on phone conversations, using spyware to quietly survey every keystroke and click one makes, and many other methods of unwanted snooping have arisen. As a result, laws have been made to make sure these negative uses are not taken advantage of by anyone. But because of how often technology changes, how can it be

In the modern society, the technology is growing at a dramatic speed. New ways of communication make the conception of privacy more obscure. At the same time, it is harder for people to actually keep the “privacy”. For example, in old days, someone could steal others’ privacy only by sneaking around; in the phone era, this can be achieved by placing the detectaphone; currently, in the internet era, with video calls, e-mails and the latest “cloud storage”, the stealer can get the information by acquiring the data from the server. Other than focusing on few people, those data allow the stealer to have a broad surveillance, and even without exposing him/herself. This “access” could be “hacking”, or something worse, a special program used by the

Many users are subject of Security and Privacy on the Internet issue. The term "information" now is more used when defining a special product or article of trade which could be bought, sold, exchanged, etc. Often the price of information is higher many times than the cost of the very computers and technologies where it is functioning. Naturally it raises the need of protecting information from unauthorized access, theft, destruction, and other crimes. However, many users do not realize that they risk their security and privacy online.

Information sent over the Internet has the potential to pass through dozens of various computer systems on the way to its intended destination. ?Each of these systems may be managed by a different system operator (sysop), and each system may be capable of capturing and storing online communications.? (www.privacyrights.org) It is possible for the online activities of Internet users to be monitored, both by their own service provider and by the system operator of any sites on the Internet that may capture them. ?There are virtually no online activities or services that guarantee an absolute right of privacy.?(www.privacyrights.org)

Technology is great in so many ways. It has provided us with more communication access, access to knowledge at our finger tips, and so much more. Technology has overall made life easier, but maybe too easy, and has made things a lot less private. This results in us having to be extra careful with security on the internet. Internet security is important to protect our privacy, protect us from fraud, and from viruses that could destroy a piece of our technology. Internet privacy and security may be different but share a responsibility, but it is up to us to take personal responsibility to protect ourselves on the internet. We should pick unique, carful passwords, and never share this sensitive information, and encrypt our data when online.
