Assignment 3 - Security Issues

Introduction

In this assignment I shall be looking at the security implications of shopping on the internet, and will also be evaluating, the reasons, why I think that the security flaws to internet shopping are minimal.

Task 1

Firstly, when looking at the security implications imposed on the internet we need to consider who the flaws are going to effect. In most cases it will be the consumer, who, ultimately will be parting with their money. Now we have considered the main threatened party we must consider what can actually affect them. These shall be listed below, whilst also taking in to consideration the effects on shop owners and other parties.

Consumer: The biggest problem that the consumer faces is that their private details are to be entered in to WebPages and then they disappear, somewhere over the internet and they have no idea where it has gone. As far as their concerned any one could access this information and then commit a fraudulent activity and steal there money. To counter this many things have been put in to place, but these will be talked about at a later stage. The problem that many of today’s public are facing is the increased attempts of members of the community in trying to steal and take others peoples money and details. For this reason many people turn away form e-commerce and stick to the more “traditional methods of purchasing, bricks and mortar being the main way.

Business Users: When thinking of the business we have a few more worries that are a little deeper than the consumer’s issues. For the business there is more on the line, normally a lot more money involved, a lot more information to be stolen and normally tend to be a bigger target for attack. With this in mind the businesses have to be a lot more careful. So how are these precautions taken? Below is a list of the most common issues that both consumer and businesses may face. Below that is an explanation (only briefly) of what the actual implications mean.

  • Disruption or denial of service attacks
  • Defacing web sites
  • Unauthorized use of credit cards
  • Invasion of privacy—especially related to minors
  • Unauthorized changes to database records
  • Fraud
  • Spreading viruses
  • Employee misuse of the Net
  • Employee privacy
  • Email harassment

Disruption or denial of service attacks

A denial-of-service attack (DoS attack) is an attempt to make a computer resource unavailable to its intended users. Although the means to, motives for and targets of a DoS attack may vary, it generally comprises the concerted, malevolent efforts of a person or persons to prevent an   or  from functioning efficiently or at all, temporarily or indefinitely.

Defacing web sites

With unauthorised access to websites (normally gained by hacking) a user can have endless possibilities to what they can actually achieve. They can re route information to themselves; this either could be the customers or the businesses information or they could deface the website, this would put customers off from coming back.

Unauthorized use of credit cards

The problems with the use of unauthorised credit cards are in fact as costly to the customer as they are to the business. With this form of theft/fraud, the customer’s card is being charged and they will in fact get the bill even when they didn’t spend any of the money. By the business accepting this payment it shows that they haven actually taken the correct method checks to ensure the customer is who they say they are. This gives the business a bad name.

Invasion of privacy—especially related to minors

Privacy is very important to the home user when purchasing off of the internet. However, when the user is under age then there must be sufficient protection. This is for their safety with the increase in child abuse and so on. Normally, however minors cannot purchase off of the internet for these reasons alone.

Unauthorized changes to database records

There are some extreme reasons why this is a very dangerous security issue when using the internet and e-commerce. The protection of someone’s data, (and the businesses own, stored data) must be looked after ...
