1. What is the difference between a threat agent and a threat?

A threat is a general term used to describe a category of items that present a risk in jeopardizing the safety of an asset. A threat agent is a more specific term used to describe an exact piece of a threat. For example, all kitchen appliances pose a threat to those who use them, while a gas stove is a specific threat agent in this case.

2. What is the difference between vulnerability and exposure?

Vulnerability is a flaw in a system that leaves it open to damage. Exposure occurs when the vulnerability is known, or exposed, to an attacker. A car that is kept unlocked is an example of vulnerability. Exposure occurs when a thief knows that the car is kept unlocked.

3. How is infrastructure protection (assuring the security of utility services) related to information security?

Information security includes the protection of information assets in storage, processing, or transmission. To assure the security of things such as schools, prisons, toads, and power plants, the confidentiality and integrity of information must be protected.

4. What type of security was dominant in the early years of computing?

Physical controls (badges, keys, etc.) were dominant during World War II, because one of the main threats at that time was physical theft of equipment.

5. What are the three components of the CIA triangle? What are they used for?

The three components of the CIA triangle are confidentiality, integrity, and availability of information. These components are used as the industry standard for computer security and they describe the utility of information.

...11. List the five steps of hypothesis testing, and explain the procedure and logic of each. Step 1: Restate the Question as a Research Hypothesis and a Null Hypothesis about the Populations. You want to restate the question as research hypothesis and null hypothesis about the populations because it allows you to think of two different samples. The research hypothesis and the null are opposite of each other. One is true and the other is not. The researcher predicts something and researches it and the null hypothesis says there will be no difference if what the researcher predicts. The logic is figuring out the probability of getting a particular result if the null hypothesis is true. Step 2: Determine the Characteristics of the Comparison Distribution In the hypothesis-testing process, you compare the actual sample’s score to this comparison distribution. The comparison distribution is the distribution that represents the population situation if the null hypothesis is true. If the null is true both samples will have a normal curve. Step 3: Determine the Cutoff Sample Score on the Comparison Distribution at Which the Null Hypothesis Should Be Rejected You will need Z scores and percentages, if a researcher decides that the score is lower than a certain percent then they would reject the null. Psychology researchers use a cutoff on the comparison distribution with a probability of 5% that a score will be at least that extreme if the null hypothesis were true. They are...

...Case 18.1 Wilson Sporting Goods Co. v. U.S. Golf and Tennis Centers, Inc. 1. What is the perfect tender rule? The perfect tender rule is under the common law, the seller is obligated to deliver goods that conformed to the terms of the contract in every detail. 2. According to the UCC, what are a buyer’s options if the goods do not conform to the contract? Does a buyer have those same options if the goods conform in every respect? Explain. The buyer’s options if the goods do not conform to the contract, the buyer or lessee may accept the goods, reject the entire shipment, or accept part and reject part. If the goods conform in every respect the buyer or lessee does not have a right to reject the goods because the buyer or lessee is obligated to accept and pay for the goods according to the terms of the contract (UCC 2-507). 3. In this case, what provision in the parties’ contract was at the heart of their dispute? The provision in the contract that was at the heart of their dispute was “that the price charged be the lowest available price.” 4. What did the court rule on the dispute between these parties? Why? The court ruled that the seller (Wilson) fully performed, but the buyer, the company, failed to make any payments. The agreed contract terms, including purchase price were clear.

A threat is a constant danger to an asset, whereas a threat agent is the facilitator of an attack. 2. What is the difference between vulnerability and exposure? Vulnerability: is a fault within the system, such as software package flaws, unlocked doors or an unprotected system port. It leaves things open to an attack or damage. Exposure: is a single instance when a system is open to damage. Vulnerabilities can in turn be the cause of exposure. 3. How is infrastructure protection (assuring the security of utility services) related to information security? The organization needs to have clear parameters and set regulation when it comes to the protection of itself. Clear goals and objectives when it comes to protection will lead to a better protection on regards to the information security. 4. What type of security was dominant in the early years of computing?

...CHAPTER 7 INTEREST RATES AND BOND VALUATION Answers to Concepts Review and Critical Thinking Questions 1. No. As interest rates fluctuate, the value of a Treasury security will fluctuate. Long-term Treasury securities have substantial interest rate risk. 2. All else the same, the Treasury security will have lower coupons because of its lower default risk, so it will have greater interest rate risk. 3. No. If the bid price were higher than the ask price, the implication would be that a dealer was willing to sell a bond and immediately buy it back at a higher price. How many such transactions would you like to do? 4. Prices and yields move in opposite directions. Since the bid price must be lower, the bid yield must be higher. 5. There are two benefits. First, the company can take advantage of interest rate declines by calling in an issue and replacing it with a lower coupon issue. Second, a company might wish to eliminate a covenant for some reason. Calling the issue does this. The cost to the company is a higher coupon. A put provision is desirable from an investor’s standpoint, so it helps the company by reducing the coupon rate on the bond. The cost to the company is that it may have to buy back the bond at an unattractive price. 6. Bond issuers look at outstanding bonds of similar maturity and risk. The yields on such bonds are used to establish the coupon rate necessary for a particular issue to initially sell for par value. Bond...

...1. The four basic differences between the information content of the fund financial statements and the government-wide financial statements are: In the fund financial statements, the current financial resources measurement focus and modified accrual basis of accounting are used.

A third difference is that fund statements include the fiduciary funds but exclude the discretely presented component units. The government wide statements exclude the fiduciary funds but include the discretely presented component units. 2. The column headings generally used in governmental wide statement of net position are governmental activities; business type activities; total of those two columns; discretely presented component units. 3.
