Teen Smoking Killing You Softly - 2315 Words

Teen-Smoking: Killing You Softly Have you ever made bad decisions as a teenager? Consider the following: alcohol, drugs, theft, DUI, and skipping school. The life as a teenager is a constant battle for social esteem, yet in the myopic quest for that ephemeral satisfaction many make decisions based on impulses that trump morality and logic; one of the most detrimental is smoking. The Centers and Disease Control and Prevention (CDC) completed a research of estimating the use of cigarettes among middle and high school students. The results were: 14% of high school students smoke cigarettes (11.7% females, 16.3% males), and 3.5% of middle schools students smoke cigarettes (3.2% females, 3.7% males). The CDC estimated the current use of†¦show more content†¦There will be consequences if that decision has a negative impact among themselves. Teenagers in Indonesia start smoking because they think that it will benefit themselves, but they don’t realize the harm it will cause when all is said and done.

It plays a vital role to provide security to the customer information. It mainly deals when the customer doing the online transactions. By this security support the customer has trusted on the E-commerce website as well as they protects their personal information from the thief’s and hackers. This day security has been implemented in a different way like Secure Sockets Layer, Integrity, Authentication, Encryption and Secure Payment. Integrity ensures of the remainders of data as is of the seller to the customer. Encryption deals with hide the information cannot spy on the others information. This report describes the security technologies in the E-commerce system and issues involving the E-commerce security technologies. . INTRODUCTION E- Commerce is also known as online commerce. E-commerce refers to exchange the goods and services over the internet. It includes retail shopping, banking, stocks and bonds trading, auctions, real estate transactions, air line booking, movie rentals nearly anything you can imagine in the real world. Even personal services such as hair and nail salons can benefit from e-commerce by providing a website for the sale of related health and beauty products, normally available to local customers exclusively. The main aim of this report conveying the security technologies of E-commerce website Security is the authorized conception in E-commerce website the main notion of security is protecting the customer personal details and banking information. Its mostly involve with four basic principles such as Privacy, Integrity, Authentication, Non-repudiation. The E-commerce website should be built on the security technology and it should be very secure. Secure Sockets layer provides support for protect pages and encrypts the whole thing a user sends-nobody else can read the data . Strong encryption and authentication certificate makes web site more secure and invites more customers. ( Lee, 2001) 2. Features of E-commerce: Ubiquity: Is the ability to be present in every place at any time, unbounded or universal presence. With help of internet it makes easier and possible for consumer and companies to be in contact with each another. The wish of customers to buy goods and services online can make so much constantly and practically any place. It reduces the cost of transaction, the cost to take part in the market and lower the mental effort required to achieve a transaction. Richness: Website richness mainly depends upon the interactivity and interaction it give the useful information on the website about each product and services for searching. It also gives more details about services what they are offering. It will make a contact between the seller and customer. Condition notices are strongly advised by the seller to understand before buying a product. Maintain vast information about products and services makes more sales and creating money making environment. (David, 2000) Global Reach: The main concept of the global reach is grabbing the attention of user’s through out the world by providing the different language in the website so that the site can be used in worldwide and it access by every one. Provide online customer services, secure the transaction processing. Site should be very interactive to the customers and giving a good quality information about products and information is understandable. Provide fast and efficient services lead to competitive global advantage. 2. 1. Security role in present E-commerce: Security plays a vital role in the present E-commerce it helps to keep secure the                               customers information and doing the secured online transactions. Every E-commerce    website giving server side security and complex on Data confidentiality, Data integrity, Availability, Nonrepudation and third party systems as supplies for facilitating E- Business transactions. Security is very helpful to the E-business. With out security customers never do the online transactions because of hackers. 2. . Security Factors in E-commerce: One of the significant success factors of E-commerce is its security, it kept secure the credit card details and extremely sensitive personal information of the customers. E-commerce security depends on a complex interrelationship between different components including the application development platforms, database management systems, and system software and network infrastructure. Privacy: Privacy makes that only ce rtified left edge reach information in any system. Information should not be distributed to the left and that should not be received it. The service off flexibility off integrity only to the approved people edge make exchanges with documents transmitted over the network Authentication: Authentication ensures that the origin off year electronic message is properly identified. Given It has possibilities to who feels the message from where gold which machine. Without appropriate authentication, it very hardware to know which passed year order and the order placed is true gold not. (David, 2000) Non-repudiation: it’s much closed to the authentication, in this sender boat refuses the sending particular messages and receiver boat rejects the receiving messages. Not-repudiation involves the technical like digital signature, conformation services and time stamps. Digital Signature has distinctive to identify for individual like written signature. Advantages of Security in E-commerce: The internet gives the much benefits to the customer through that the customer can has a chance to browse and do shopping there suitability and their place. They can access the service from office and home as they like it is available 24/7. †¢ Protect the privacy and reliability of network transactions. †¢ Encrypted and secure payment online. †¢ Increase the volume of purchases, improve the relationship with customers. †¢ With the help of e-commerce can promote products globally. †¢ Identify the users and merchants on the network. †¢ Look after E-commerce website and enterprise networks from attacks by hackers. †¢ Protect the personal information of E-commerce users. 3. Security Technologies: Security is the most important issue for E-commerce it gives security to the website, these security services are provided to ensure basic E-commerce requirements. Security services provide a way for safe, authentic, and reliable communications between two or more parties. Security not only includes that the information stays within the communicating parties but also it can be verified and noted as authentic. Signing of contracts, registration of mail, disclosures, anonymity, and authorization schemes of the real world must be able to be replicated and done in the electronic world. . 1. Secure Electronic Transaction (SET): Secure Electronic Transaction (SET) is a system for ensuring the security of financial transactions on the Internet. It was supported initially by MasterCard, Visa, Microsoft, Netscape, and others. It is one of the international security standards in E-commerce. SET is a protocol proposed by a number of groups and different companies. It’s mainly focus on gi ving guarantee security for electronic payment. SET including some key technologies such as shared key, public key, digital signature, electronic envelop and electronic certificate. After this there is a problem with operating systems and application systems, on these basis hackers improved their attack skills on customer information. Key Security Elements: E-commerce using different key security elements such as Electronic Data Interchange (EDI), E-mail, Electronic fund Transfer and other internet technologies lead to exchange the information of business with individuals, companies and countries. It makes transactions safe and more reliable. Encryption and Data Integrity is one of the key technologies in E-commerce, Encryption is the major security measure adopted in E-commerce. It can make sure confidentiality of information in the transaction process like PIN of credit card 3. 2. Secure Socket Layer (SSL): The SSL protocol was originally developed by Netscape, to ensure security of data transported and routed through HTTP, LDAP or POP3 application layers. SSL is designed to make use of TCP as a communication layer to provide a reliable end-to-end secure and authenticated connection between two points over a network (for example between the service client and the server). Notwithstanding this SSL can be used for protection of data in transit in situations related to any network service, it is used mostly in HTTP server and client applications. 3. 3. Firewall: A firewall is a barrier to keep destructive forces away from your property. In fact, that’s why it’s called a firewall. Its job is similar to a physical firewall that keeps a fire from spreading from one area to the next. Firewalls are essential elements in e-commerce security strategy it is used to protect the e-commerce applications and website. Firewalls needed clearly defined security policies must be correctly installed and maintained to afford consistent and efficient security protection. It’s mainly addresses the problems such as Denial of service and Distributed denial of service. Firewalls working as a hardware and software, it prevents unauthorized persons access the private networks connected to the internet. 4. Conclusion: Finally conclude that the security is very significant when designing year E-trade website. E-trade has increasingly become the mode off conducting business. The purpose off this resulting paper is to stimulate discussion one the question concerning the security system off E-trade; things increased in the paper are not regarded ace conclusive. It hopes that suitable information will be identified for discussion 5. References: Chan, H. , Lee, R. , Dillon, T. , ;Chang, E. (2001). E-commerce: Fundamental Application.

Transaction Processing System

Question: What options are available for GOLFSMITH in terms of software and applications? If the CEO likes the idea of purchasing software, what are your next steps? What is a logical design? What is a physical design? Describe the steps typically performed in systems design. Answer: Introduction Transaction processing system is a style of processing data which divides the work into individuals and inseparable operations named as transactions. Golfing Tools are manufactured and then retailed by Golfsmith organization. Apart from the Retail outlets, this organization has a good hold on the Web in entire U.S.Organization is now required to install transaction processing system and an order entry framework. Transaction Processing System Transaction processing system (TPS) is a software framework or a combination of software or hardware that supports easy or simple transaction processing of data (Brown, 2000). Proposal of recommendation Plan of Action As an IT manager, I suggest that CEO of GOLFSMITH should take consideration of different TSP software and Cloud Models available in the market for the better transaction of data and check appropriate new order entry cloud systems available in the market. Features and applications of available software should be checked properly (Guo, Papaioannou, Aberer, 2014). Options of TPS Software Tuxedo is the middleware model utilized to manage the distributed data transaction processing within distributed computing situations. Tuxedo is a data transaction processing framework, a transaction-familiarized middleware and it is an industry based application server available for numerous systems and for different programming languages. On the other hand, cloud model is also suitable for TPS and new entry system because implementing cloud computing is the best business approach for Golfsmith (Linthicum, 2016). The most significant distributed computing model in cloud computing is Hadoop, which is an open source cloud model developed by the organization Yahoo for the large scale transaction processing. Selection of Cloud or Tuxedo As an IT Manager, I recommend the CEO of GOLFSMITH that he should go with the Tuxedo Transaction Processing System or use it as a new entry system as there are a lot of benefits associated with it. Oracles Tuxedo empowers appropriated applications to the scale which responds to the change the transaction loads by dynamically spawning as well as terminating servers and by dynamically deactivating and activating objects to meet the employment needs. Oracle Tuxedo adjusts the workload among every accessible service and objects to guarantee that they should be equally utilized (Song, Li, Zhou, Li, 2013). Steps for buying Tuxedo Oracle Tuxedo offers a middleware framework for building a scalable multiplier client or server applications within heterogeneous and distributed situations that broaden the Web applications for the Enterprises. By utilizing Oracles Tuxedo, clients can develop, arrange and convey the distributed applications severally on the underlying hardware, software, operating system, as well as database environment (Su, 2015). Physical design Physical Design for Oracles TSP demonstrates: Person or Machine Boundaries Architecture of Network Technology Assignment Distribution of Process Data Distribution Logical design Logical design is made by separating procedures such as: Time Client and Server Place Distributed vs. Centralized Batch vs. Online Automated vs. Manual System design Implement the transactions utilizing two-phase submit a protocol. In the initial phase,the coordinator requests for every LTMs as well as to take care that the operation or function essential for this has been executed correctly. If each LTMs vote positively, then they execute the second phase in which Tuxedo actually submits the transaction. Otherwise, the data transaction is prematurely ended. Then they allot data products to LTMs utilizing steady hashing. To accomplish an adjusted task, initially, cluster the data into virtual hubs and then allot such virtual hubs to LTMs. Different virtual hubs can be allocated to the similar LTM.To overcome the LTM disappointments, virtual hubs along with transaction states are replicated into many LTMs. After the LTM server disappointment, the recent updates or overhauls can then be recuperated and the influenced data transactions can proceed with the implementation phase by fulfilling ACID properties. At last detailed configuration or designin g of TPS is done to ensure the Atomicity, Isolation, Durability and Consistency properties of data transactions (Vinje, Marsland, Grtner, 2012). Cloud model for data processing Software as a Service is the model which is a delivery and software licensing framework in which the software is authorized on a membership premise and it is a centrally hosted cloud model.SaaS cloud model includes numerous services as well as applications such as reliable and secure transaction of data. GOLFSMITHs success depends on upon the reliable handling or processing of data transactions to guarantee that the orders of the clients are delivered well in time. The SaaS is a cloud model which helps the organization to enter reliable data in the new systems (Linthicum, 2016). Conclusion In this study it has been concluded, that to accomplish performance, consistency and reliability, data is promptly accessible within data warehouses, reinforcement processes must be placed as well as the recovery procedures must be established to deal with Human failure, Systems failure, viruses in computers, software applications and with natural disasters. It has also been concluded that by utilizing Oracle Tuxedo, clients can develop, organize and convey distributed applications autonomously. References Brown, R. (2000).
