Though technology have been a major contribution in the security of people’s money, it has also been used as a tool for internet hacking and identity theft. Since the invention of computers and the internet, it has been common today for people to constantly upgrade their security systems. With major bank companies, it has been made easier to make payments with the slide of a card. However, because of technology, it has also been made easier for hackers to rob people of their money and personal information. As of recent years, there have been a major increase of online shopping as it is extremely convenient for a lot of people. And as convenient online shipping may be, it is also one of the causes for stealing credit card information. People are able to make fake websites and steal a person’s credit card info.

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.

In this era of globalization and cut-throat world of competition, it is virtually impossible to do business without using the internet and web applications. Internet gets used for processing the credit card or debit card sale and even for using to save the data of customers to the merchant’s database for future reference and to send promotional offers to the previous and patron customers. And on the other hand, hackers are trying their best to get the data stored on the merchant’s server by spoofing

Developing the skills required to ensure best practice in the Information Technology world starts here and now. Cyber-criminals, hackers, pentesters, corporate espionage, and disgruntled employees are everyday annoyances IT professionals will find themselves devoting massive amounts of time to, while maintaining their respective networks' functionality for legitimate users. The field covers all the processes and mechanisms by which computer-based equipment, information are protected from unintended or unauthorized access, modification or removal. Computer security is a critical part of technology as it grows in our daily lives.

Security in information technology is a paramount feature which impacts on user usage and efficiency. Security in organization such as Barclays bank is crucial since it does protect the details of the clients as well assets of the bank. Services such as electronic funds transfer, automated teller machines and mobile banking have brought new security challenges. Security measures are an attempt to reduce risk as well losses due to muggings, unauthorized users, insider manipulation, fraudulent card use and many more (Hess, 2010).

Internet security protocols use many different methods to protect your computer from dangers across the internet. Because there are so many methods to do this with, there are also many protocols concerning internet security. Internet protocols as a group are often referred to as TCP or IP. TCP stands for Transmission Control Protocol and IP stands for Internet Protocol. Internet Protocol will deal only with packets but Transmission Control Protocols allows more than one host to connect and exchange the data they see fit to share. Transmission Control Protocols not only make sure that your data gets delivered but that the packets sent by you will be delivered in the order that the user sends them.

The internet has been a wide usage in all the fields in the present competitive world. It is being used in the education, research, business and what not, in everything. But providing security for the users information or transactions or any other data in any of the field has become a paramount. This paper gives a vivid picture of “E-commerce” and the vulnerabilities they are facing in providing a secure system for the users. In other words, how the security attacks are made either by the hackers or the intruders, the ways how they attack and exploit to illegitimate means.

As the number of people utilizing the internet increases, the risk of security violations increases with it. It is true that sometimes the cost of protecting the network outweighs the cost of just leaving it unprotected, but it is undeniable that the cost of protecting the network becomes nontrivial as more services such as electronic wallets become available. Some of the threats that stimulated the upsurge for people with the lack of security were compromise of clients ' financial details (credit card numbers, etc) which may result in the unauthorized transfer of funds, development of a method of obtaining the goods or services without making the appropriate payment and other methods permitting the unauthorized transfer of funds. Regardless of how a payments system is constructed these attacks are always more or less practical although some techniques can virtually eliminate the risk of one or another.

Definition of Wireless LAN is Wireless Local Area Network (WLAN). WLAN is a wireless computer network that connect two or more devices by using a wireless distribution method within a limited area such as home, room, school, computer laboratory, library or office building. Besides, WLAN gives users the ability to move around within local coverage area and yet still be connected to the network. Most modern WLAN’s based on IEEE 802.119 (extended protocols for WLAN), marketed under the name of Wi-Fi.

Information security has become a fundamental aspect of successful running of any company. Consequently, there is a growing need for secured communication to ensure companies and their clients enjoy the benefits that the advancement of the internet has brought. As such, adequate measures in security of information need to be implemented with competency. This is because there is a growing risk of exposure of companies’ information through attacks from malicious people and other risks. This paper will develop an information security plan NextGard Technologies (British Standards Institution, 2001).

As the online services offered through internet has progressed and computing systems have become much more complex, security and privacy issues have become essential. Generally, Information system security should be able to provide user’s confidentiality, data integrity, data availability whenever a legitimate user wishes to access, in this context security can be divided into four areas as follows: Confidentiality, Integrity, Authentication and Non-Repudiation [23].

The incredible development of the internet has begun a booming of both business and individual communications leading to the expansion of e-mail and e-commerce. As a matter of fact, studies indicate that most of the internet communication content is e-mail content. The result of this is the continuing demand concerning security and privacy in electronic communication. The call and want for privacy and security has led to the arrival of proposals for security that are discussed in the following contents of this paper.

people who use internet communicate various ways such as electronic mail, or the use of world wide web brewers. Both of these communication are not secure for sending and receiving information. In addition, the information sent over the internet include sensitive personal data which may be intercepted. The commercial activity that is going on the internet and many web sites requires from the user to fill forms and include his/her sensitive personal information such as telephone numbers, address, and credit card information. To avoid this risk and to be able to do that users would like to have a secure, private communication with the other party. Every online users needs private and secure communications for other reasons as

Security is the test confronting e-business today & there is still a considerable measure of headway made in the field of security. The principle

Apart from the admirable functionality of the site, users should always be concerned about the security issues of the system. The massive increase in the drift of e-Commerce has led to a new generation of associated security threats and thus, the site focuses on major security issues like-
