What happens if you don't give a complete service (the computer doesn't react to the user)? Previously, a 10% denial of service assault (slightly slower processing) created substantial issues for customers. Unauthorized users may deny legal users service if they get access to a computer system. So, how do you proceed if that is the case?

In order to provide an additional degree of protection to the process of making electronic payments, certain credit card companies now supply their customers with credit card numbers that can only be used once. Customers need to go to the website of the entity that issued their credit card in order to get the one-time-use number. Compared to the conventional means of using credit card numbers, what are the benefits of applying this technology instead? What are the benefits and drawbacks of using this method as opposed to authenticating yourself using an electronic payment gateway?

Give an example of how a full denial of service attack on a user (in which the user gets no response from the computer) results in a significant issue for that user. Another example is offered in which a 10% denial of service (that is, the user's computation advances but at a 10% slower pace than normal) is a significant issue for that user. Illegal access to a computer system may result in a 10% denial of service attack against legitimate users of that computing system. If so, how would you proceed?

For each event, specify an algorithm that shows how the system changes when this type of event occurs. There are four scanners: three normal scanners and one Sniffometer.- When a passenger arrives they are randomly assigned to queue up for a scanner.- The regular scanner takes 5 seconds to check a passenger.- The Sniffometer takes 20 seconds to check a passenger.- The regular scanner is set off by 10% of passengers.- The Sniffometer is set off by 1% of passengers.- Anyone who sets off a scanner must spend an extra 200 seconds receiving a secondary screening.

When a piece of software that people rely on stops working properly, it may be quite inconvenient for those individuals. Companies sell software of which they are aware to have bugs that might result in the program's malfunction; the question is, do these companies have a moral duty to reveal this information? Should they be required to compensate their clients financially in the event that their software malfunctions and results in monetary losses for those clients? Why shouldn't the software business be forced by law to guarantee its products? Manufacturers of consumer items are obligated to guarantee their products.
