Mis Development Essay Example For Students

Mis Development Essay MIS DevelopmentThe term Management Information Systems (MIS) has come to refer to a wide range of applications of computers to data processing and analysis problems in the private and public sectors. The pace of developments in computing in general, and MIS in particular, is breathtaking. Traditional concepts of how computers can and should be integrated into businesses are being challenged by worldwide telecommunications and transmission of sound, graphics, and video alongside of text. Virtually all successful businesses use computers extensively. If you dont like computers, and want to have a career in business that involves little use of them?think again. You dont have to like them, but you will have to deal with them extensively. This is a fact of life along with the hole in the ozone, Oklahoma City, TWA 800, AIDS, and The Real World on MTV (now in its fifth season!). Computers can have a profound impact on the way that power is distributed in society. Those who ignore computers are apt to be left out of important decisions. You may even become the person in your firm who has responsibility for your firms use of information technology. Nevertheless, many people have little understanding of what computers are and what they can do. There is a desperate need in our society for liberally educated people who are able to balance the enormous possibilities of computing with its potentially harmful consequences. In the business world, there has been a gap between those who are computer smart and those who speak the language of business. You need to know enough about computers to be able to: understand how computers support decision making and how they can be used to obtain strategic advantages; understand the challenges posed by the rise of the Internet; understand how the computer works in order to have a feel for the computers limitations; understand how data is stored and managed; understand how to store and retrieve data yourself; understand the different types of computer systems and when one type or another is appropriate; understand how the overall parts of an MIS system work together and what some of the functions that they accomplish are; understand how to state computer system requirements and understand h ow computer systems are built; understand how computing is managed in the corporate environment; understand some of the social issues which computers raise. Achieving these objectives will give you the tools you will need to function effectively in the business environment. Bibliographywww.gorgetown.com

Wireless Networking Concepts WPAN Technology

Question: Discuss about theWireless Networking Conceptsfor WPAN Technology. Answer: Compare and Contrast Three Data Encryption Standards for Wi-MAX Networks Table 1. Comparision of, 3DES, AES and RSA9+6 PARAMETERS 3DES AES RSA Definition DES is a kind of WI-MAX networks. DES stands for data encryption standard cipher algorithm. It is a 56 bit key (SHARMA, 2014). Data encryption alone may not be sufficient. So the DES key size will be extended. Three different keys will be used for this purpose. It does it by three times applying succession algorithm. AES is a kind of WI-MAX networks. AES stands for Advanced Encryption Standard algorithm. While encryption and decryption process, data and key length may vary based on many factors and AES supports all of them. RSA is kind of WI-MAX networks. RSA stands for Rivest-Shamir-Adleman is a well-known public key encryption of blocks of data key exchange encrptosystems. It has two private keys i.e., public and private keys. Key Length 3x56 = 168 is the combined key size. K1, K2, K3 are used while TDEA is in EDE (Encrypt-Decrypt-Encrypt) mode. The plain text is encrypt K1 and decrypt with K2 and encrypt with K3.It is mutually independent keys with space 356 = 168 bits and also have two mutually independent keys, the third key same as the first key. The independent keys pace is 2 56= 112 bits. It can use 256 bits key length in AES-256. 128, 192 are also used in AES-128, AES-192. ("DATA ENCRYPTION STANDARD", 2016). n=p*q where p and q are random prime numbers. The modulus n will be having some bits length and key length is based on n. Block Size 3DES has 64 bit block size. For each encryption, encrypt the block that has 64 bits of data. Got data length of 128. Four operational blocks are constituting this 128 data length. RSA has a variable bit size of encryption blocks. Cipher Type 3DES is a Symmetric Block Cipher. It consists of k1, k2, k3 keys for mutually independent. AES is a Symmetric Block Cipher. RSA is an Asymmetric block cipher. Number theory is the basis for this public key based asymmetric cryptosystem. Round(s) 3DES has 48 Rounds for 168 bits. While retrieving the original plain text, 128 bit keys will take 10 rounds, 192 bit keys takes 12 rounds and 256 bit keys takes 14 rounds in AES based system. RSA has 1 round for large random prime numbers. Speed Encryption level and average time is increased by 3-times iteration. This causes enough slowness when compared with other cipher methods. AES is fast when compared with others. RSA is a slowest one because it has large p and q length. Security 3DES has enough Security to sending and receiving date. AES has excellent Security when compared with others. RSA has least security when compared with others. Encryption Time 3DES has minor encryption time. AES encryption time is minor. RSA has the longest encryption time. Memory Usage 3DES has 2^56 blocks of memory. So the memory usage is high. The memory usage of AES is very low. The memory usage of RSA is very high. Created By This was created by IBM in 1978. This was created by Vincent Rijmen, Joan Daemen in 2001. Ron Rivest along with Adi Shamir and Leonard Adleman , in 1978 , developed this. WPAN Technology Security Challenges WPAN Technology The WPAN stands for Wireless Personal Area Network. It uses the IEEE 802.15 standards which is limited for certain area only. This helps in interconnecting the devices in the locality. There are many IEEE standards which are differentiated in terms of rate, protocols and routing, and some of them are as follows (Yadav, Kanodia, Grewal Dangi, P. Panda, 2016): 15.1 (Bluetooth) 15.6 15.10 15.3 (High Rate WPAN) 15.9 15.4 (Low Rate WPAN/ZigBee) ZigBee WPAN Technology Among various WPAN technologies, ZigBeee is the best form of wireless technology. This technology helps in creating (PAN) personal area networks. This in turn is created with the help of radios waves which has less power. Thus, it is mainly used for transferring less amount of data in a short range. The ZigBee follows the IEEE 802.15.4 standard. The battery in ZigBee are generally not rechargeable and provides network speed till 250 Kbps. It can cover an area ranging from 70 to 400 meters (Yadav, Kanodia, Grewal Dangi, P. Panda, 2016). Security Challenges: ZigBee There are various ZigBee wireless attacks therefore, security is important. The 802.15.4 protocol's security features are considered for manufacturing and implementing these protocols in the devices. Every time the only part where the security risks arise are in implementation part. (Bowers, 2012). The attacks that are against the ZigBee are as follows (Bowers, 2012): Physical Attacks This type of attack ensures to gain access of the device which contains ZigBee radio by the attacker. The encryption key and the ZigBee network is used for gaining the physical access. The keys are just flashed on all the devices of a ZigBee network (Bowers, 2012). Key Attacks The other sort of attack can be based on remote access for gaining the encryption keys. If the attacker uses both the hardware and the software-based tools, then it can perform unlawful activities. In order to increase the complications, the attacker can utilize the high-powered transmitters or special Yagi antennas. The attacker will be able to hack from any remote are without any range limit (Bowers, 2012). Replay and Injection Attacks This is the last sort of attack and is based on the key-based attacks that are blended with packet replay or with the injection attacks. This helps in tricking the ZigBee devices for performing the unauthorized actions. The ZigBee radios responses well to these attacks (Bowers, 2012). Bluetooth WPAN Technology Bluetooth is a Radio specification designed for replacing the cables as the medium of data between the electronics devices (HAATAJA, 2009). Security Challenges: Bluetooth Bluetooth offers advantages and benefits. The bluetooth contains four security modes, in which two are optional. They are, the entire connection will be secured and that which contains policies for all the applications. As the bluetooth security is turned on, the devices automatically send challenge-response messages. This contains the static device PIN. The authentication process requires encryption key for scrambling the data that is forwarded to the other device. But the fact is that the bluetooth is weak in nature to provide security. This is because the PIN and the encryption keys are of variable length. Moreover, the lengths are short and this is the reason why it doesn't provide security ("Can you tell me about security in Bluetooth technology?", 2016). The following are the security challenges faced in bluetooth devices: Integrity threat The recipient can be confused by continuously altering the information (Ibn Minar, 2012). Denial of service (DOS) threat The accessing service for accessing the other devices is blocked. This block ensures to makes the authorized users unavailable (Ibn Minar, 2012). Disclosure threat There is a possibility, that the information can be leaked. This leak happens from the user's system to an eavesdropper. These are the ones who have no authority to access any sort of information (Ibn Minar, 2012). Bluesnarfing The Bluesnarfing is serious when compared with the bluejacking. This can permit to leave certain information open that are present in the smartphones. The softwares are used to accomplish this purpose. This type of hacking is even made possible when the devices are in "invisible" state. The information can be the bank details. ("Hacking Bluetooth Devices: Bluebugging, Bluejacking, Bluesnarfing", 2014). Bluejacking The bluejacking is a form of hacker's threat. This is a common type of hacking. This takes place when the discoverable devices are being searched by the hackers in the area. Later the hackers sends the spam to the devices. The spam is generally in the form of text message ("Hacking Bluetooth Devices: Bluebugging, Bluejacking, Bluesnarfing", 2014). Blue bugging The complete accessing of the device is possibly gained by the hacker, if he Bluebugs an individual's mobile. All the contacts, photos, applications and so on can be accessed easily. This takes place when the devices is set to "discoverable" state. This is the most difficult for of hacking when compared with Bluesnarfing and Bluejacking ("Hacking Bluetooth Devices: Bluebugging, Bluejacking, Bluesnarfing", 2014). References Bowers, B. (2012).

Henry V And Flashbacks Essays - British Films,

Henry V And Flashbacks In Henry V there are three flashbacks, which help the audience understand Henry and the plot better. The three flashbacks are the scene with Henry and Falstaff, Henry and Bardolph, and the scene at the castle in England where there is a constant flow of images in which Henry is recollecting the past events in the movie. These three flashbacks display a great deal of information that the play did not give to its readers. The first scene was with Henry and Falstaff drinking and having a good time. It was used to show that Henry got along with the common people and in addition it also how Henry cared about how his subjects thought about him. Falstaff died of a broken heart. He died because during Henrys coronation, Henry disregarded Falstaff as if he never existed. Henry could not be friends with Falstaff when he was crowned king due to the fact that Falstaff was not a noble person to have around because criminals constantly surrounded him. As a result Henry chose his thrown over his family. The second flashback showed the just side of Henry. Bardolph was also friends with Henry while Henry was a prince. They drank alcohol and partied till dawn, always having a good time. However, when they reached France to battle, Bardolph began to steal from the French and as a result he had to be hanged because of that. The flashback was set up in one of the parties that Henry had with Bardolph, Nym, Pistol, and Falstaff. Bardolph told Henry that when he becomes a king never to hang a thief. Henrys response was that he will never hang a thief but Bardolph will. What Henry actually meant was that the actions of the thief such as Bardolph would get himself killed. This showed how Henry was just because he did not care about the status of any of his soldiers, if they broke any laws than they would get punished with the full severity of the law. The third flashback was not concentrated on a specific event, but rather on a stream of images that was in the movie. It was set up in the castle when the King of France was signing the treaty with England. It showed what Henry and his men had to go through to attain France and now they were relieved that their hard work had paid off. Now Henry can rule both France the same way he is ruling England. This scene shows how Henry is pleased that the killings have stopped and now he is looking forward to ruling both lands. These flashbacks are definitely needed for todays audience because they contain a great deal of information that could help the viewer understand the play. For instance I did not know how close Henry was to Falstaff and Bardolph. The flashbacks helped me to see how close of friends they were and how just Henry was during his reign. Without the flashbacks I would have never known how close these three men were and how Henry was just by treating all his servants equally. I my self would use more of flashbacks to give more information to the viewers. A flashback that I would use would be of Edward the Black and his destruction of France. I would use the flashback in Act II Scene IV where the king of France is talking to the Dauphin and the Constable of France about the destruction brought about by Edward. This flashback would show the reason as to why so many feared Edward the Black in France Shakespeare Essays

Spam and cyber attacks Essays

Spam and cyber attacks Essays Spam and cyber attacks Essay Spam and cyber attacks Essay A traffic Jam on a real highway can effect that road and any other roads that connect to it and the same can be true for the information highway. And while most traffic Jams are a result of an accident or too many vehicles (or data packets in the case of the Internet) legitimately trying to get from place to place, they can also be slowed down deliberately, as happened in Brussels last September when about 100 trucks slowed traffic entering the city as part of a planned protest. Last week, a small Dutch Internet service provider called Cyberpunk initiated a traffic Jam of its own. Its apparent goal wasnt to slow down he entire Internet but to bring down the services of Asparagus a spam fighting organization that had added Cyberpunk to its block lists for allegedly allowing its customers to send spam around the world. Cyberpunk advertises that customers are allowed to host any content they like, except child porn and anything related to terrorism. Everything else is fine. According to published reports, that traffic Jam affected servers around the world and impacted ordinary people thousands of miles away who werent able to watch online video or access other Web services as a result of a protest on another continent. Its a scary thought and a reminder of how this global village we live in is so interconnected that we can no longer afford to ignore problems that affect other people, because they can affect us, too. Of course thats long been true to a certain extent a fire in an oil field in the Middle East can affect gas prices in our Midwest; a poor wheat harvest in Kansas could affect bread prices in Russia; a storm in New York can affect air traffic in San Francisco. But on the Internet, the impact can be immediate and widespread. This is one reason international bodies such as the United Nations hold occasional global forums like he Internet Governance Forum or the International Telecommunications Union (TU) World Conference on International Telecommunications to talk about coordinated strategies to keep traffic flowing on our global highway. Of course, even these bodies are not without their controversy. Late last year, the United States led a coalition of countries Tanat retunes to slang an International electroluminescent Regulations treaty because it proposed regulations that many Western countries considered to be a threat to the open Internet. Without getting into the specifics of the TIT treaty, the mineral issue of control versus openness is one that needs to be looked at in light of todays threat landscape. We need global cooperation to help thwart attacks and keep traffic moving. But we dont need cyber police around the world stopping traffic for no legitimate reason Just to see whats in the trunk, so to speak. Solving international cybercafà © poses both legal and technical challenges. Dave Rand, who co-founded the Mail Abuse Prevention System (MAPS) and is now a technical fellow at Trend Micro, pointed out in an interview that its possible for spam to be sent from Antigen advertising a virus site in Canada with payment processed in the Virgin Islands, and with domain name servers in the United States and a fulfillment service in India. Where does law enforcement start? He asked. Its very difficult for law enforcement to get a handle on it because there are no effective transnational laws for the Internet. Finding a way to balance privacy, security and the legal aspect of the Internet as a whole is a deep dark problem, Rand said. Rand said its up to the private sector to apply appropriate pressures at the right time. He pointed to an example from 2008, wh ere a series of articles from then-Washington Postcolonial Brian Krebs pressured upstream Internet service providers into cutting off access to McCoy, a San Jose-based company that was hosting spam sites. At that moment, said Rand, spam on the Internet dropped by more than 50 percent. Rand said that its time to put international pressure on Cyberpunks upstream providers that link them with the global Internet. I might add that its also appropriate to continue international conversations about beefing up cross-border cooperation and international laws that can help protect the Internet. I am well aware of the potential for overvaluation or oppressive laws, as we found at that last TIT meeting, but we also need to find better ways to protect our shared infrastructure while also protecting national sovereignty and an open Internet. This post first appeared in the San Jose Mercury News. Read the Huffing Post article, Dealing with spam and cyberneticss: Control vs. Openness, which can be found on the course website in the week 11 section. Requirements: Research the topic thoroughly and write a report that looks at all the ethical issues involved in both having a proprietary injector and making the decision to change it as Apple has done. Ensure you cover the following points in your report: Describe the ethical issues from the customers point of view. Describe the ethical issues from Cyberpunks point of view. What obligation does Cyberpunk have to its own customers and the general population? What are the difficulties in attempting to develop effective transnational laws for the Internet? Support your arguments with at least three references from reputable sources such as books and journal articles relevant to the subject.

What is sociology, anyway Why bother to study it Essay

What is sociology, anyway Why bother to study it - Essay Example The official and the most likely reason for the US war on Iraq is not aligned with the author’s claim that war occurs because a lack of understanding of each other’s behavior. There was also no justification for what Hitler’s and his Nazi party was doing prior to World War II, thus not understanding the Nazi culture was not a justifiable excuse for the US and its allies not to have gone to war with Germany. Sociology can be defined as the scientific study of human society and social behavior (NesSmith, pg. 5). The author of the article had a lot of good ideas about the importance of sociology to our society. An innovation that has helped the global society connect more has been the internet. The internet allows for instant communication from people from different parts of the world and provides its users with a vast database of information that can be used to learn about other people’s culture. The culture of each nation across the world is different, but these differences are what make the planet a unique and interesting place to live

Economy and Tourism of Cyprus Research Proposal

Economy and Tourism of Cyprus - Research Proposal Example Cyprus as a whole is now an open, free-market, service-based economy with some light manufacturing (TDS, 2008). Since 1st May 2004, Cyprus has accession to the European Union, which is an important milestone in its recent economic development. The Cypriots are the most prosperous people in the Mediterranean region. It has good, educated English-speaking population, good airline connections and an excellent telecommunications. The economic activity in Cyprus had been based on agriculture in the past but in the past two decades there has been a shift towards light manufacturing and services. Today agriculture contributes only 3.2% to the GDP while industry and construction contribute 19.2 percent and the services sector including tourism contribute 77.6% to the GDP employing 72.1% of the labor force (TDS, 2008). Cyprus has very few proven natural resources although the government is trying to explore the possibilities for offshore oil and gas reserves off its southern coast. The GNP growth rates have declined as the Cyprus economy has matured over the years. Public finances have improved considerably and the fiscal deficit which had peaked in 2003 was eliminated by 2007 (TDS, 2008). There was fiscal surplus in 2007 and the public debt declined simultaneously. The Cyprus economy got a further boost when Euro replaced the Cyprus pound as Cyprus’ national currency. This is expected to bring about a higher degree of price stability, lower interest rates, reduction of currency conversion costs and exchange rate risk, and increased competition through greater price transparency. The investment climate in Cyprus is conducive to FDI. There is increased flow of FDI particularly from the EU. Cyprus has good communication system, an educated labor force, good airline connections, and a sound legal system and provides modern infrastructures and tax incentives for business houses. The cost of living in Cyprus is low which
