This can give administrators a head start in fixing problems and will, hopefully, let IT organizations more effectively beat bad guys to the punch."
The above factors are only true when vulnerability systems find all the problems that may be present in an application.
Research has often demonstrated a gap between the best vulnerability assessment tools and the weaknesses in a test network. However IT employees who are responsible for securing IT assets will find the use of a vulnerability assessment tool beneficial even if all it does is eliminate some of the monotonous work they are confronted with.
When vulnerability assessment tools were first made available, scanning was the primary method utilized. However, today there are also tools such as intrusion-detection software (IDS); this software is different from scanning software in that it works by looking for patterns of illegitimate network traffic that might be consistent with a breach of the system. On the other hand, scanners work by identifying whether or not a computer's actual configuration is vulnerable to attack. In other words the IDS is reactive, whereas the scanning software is proactive.
EBay and Amazon
Now that we have discussed the general vulnerabilities that online businesses are confronted with, let us focus on and compare some of the vulnerabilities that specific companies have to deal with. As it relates to this aspect of the discussion we will focus on EBay and Amazon, two of the largest online businesses in the world.
EBay is the largest internet auction site in the world. The company has been able to generate billions of dollars a year by simply serving a host site fro people all around the world that want to offer products for sale. Although the company has been extremely successful, the very structure of the company makes it vulnerable to some very unique threats.
The first of which is auction fraud. Auction fraud is the most reported type of internet fraud and cost EBay and consumer millions of dollars each year. This type of fraud occurs in several different ways. The primary way that this type of fraud is committed involves sellers that advertise a product, the buyer or winning bidder pays for the product and the product is never received. An article entitled Online Auction Fraud: Are the Auction Houses Doing All They Should or Could to Stop Online Fraud?
Some online sellers have put items up for auction, taken the highest bidder's money, and never delivered the merchandise. In addition, consumers who paid by certified check or money order have little recourse when it comes to getting their money back.(21) With fraudulent online auction users recognizing the difficulty in retrieving a check or money order, it is not surprising that payment by check or money order accounts for ninety-three percent of fraudulent payments.
This type of fraud is problematic for EBay because if the seller never receives the product the buyer can then refuse to accept the charges and EBay will not get there commission from the sell.
To avoid this problem the company has attempted to implement several safeguards that include allowing the buyer to file a complaint with EBay. EBay then investigates such claims and attempts to rectify the situation. The company also allows buyers and sellers to leave rating for one another. On EBay an individuals ratings help others to determine whether or not the buyer or seller is trustworthy and whether doing business with the individual will end in a successful transaction. If potential buyers see negative ratings there are less likely to do business with that individual.
As it relates to more general threats such as identity theft EBay attempts to use safeguards such as password protection and usernames to safeguard the personal information of users. The company also recommends that users change their passwords frequently, as this decreases greatly the likelihood of their identities being compromised.
Although EBay has attempted to implement many safeguards, the company has experienced major problems with "Spoof Emails." According to Ebay's Security Center this is actually...
