Question 552

QUESTION NO: 547 What is the highest amount a company should spend annually on countermeasures for protecting an asset valued at $1,000,000 from a threat that has an annualized rate of occurrence (ARO) of once every five years and an exposure factor (EF) of 30%? A. $300,000 B. $150,000 C. $60,000 D. $1,500

Answer 552

C Explanation: The cost of a countermeasure should not be greater in cost than the risk it mitigates (ALE). For a quantitative risk assessment, the equation is ALE = ARO x SLE where the SLE is calculated as the product of asset value x exposure factor. An event that happen once every five years would have an ARO of .2 (1 divided by 5). SLE = Asset Value (AV) x Exposure Fact (EF) SLE = 1,000,000 x .30 = 300,000 ALE = SLE x Annualized Rate of Occurance (ARO) ALE = 300,000 x .2 = 60,000 Know your acronyms: ALE -- Annual loss expectancy ARO -- Annual rate of occurrence SLE -- Single loss expectancy

Question 715

QUESTION NO: 710 For competitive reasons, the customers of a large shipping company called the "Integrated International Secure Shipping Containers Corporation" (IISSCC) like to keep private the various cargos that they ship. IISSCC uses a secure database system based on the Bell-LaPadula access control model to keep this information private. Different information in this database is classified at different levels. For example, the time and date a ship departs is labeled Unclassified, so customers can estimate when their cargos will arrive, but the contents of all shipping containers on the ship are labeled Top Secret to keep different shippers from viewing each other's cargos. An unscrupulous fruit shipper, the "Association of Private Fuit Exporters, Limited" (APFEL) wants to learn whether or not a competitor, the "Fruit Is Good Corporation" (FIGCO), is shipping pineapples on the ship "S.S. Cruise Pacific" (S.S. CP). APFEL can't simply read the top secret contents in the IISSCC database because of the access model. A smart APFEL worker, however, attempts to insert a false, unclassified record in the database that says that FIGCO is shipping pineapples on the S.S. CP, reasoning that if there is already a FIGCO-pineapple-SSCP record then the insertion attempt will fail. But the attempt does not fail, so APFEL can't be sure whether or not FIGCO is shipping pineapples on the S.S. CP. What is the name of the access control model property that prevented APFEL from reading FIGCO's cargo information? What is a secure database technique that could explain why, when the insertion attempt succeeded, APFEL was still unsure whether or not FIGCO was shipping pineapples? A. *-Property and Polymorphism B. Strong *-Property and Polyinstantiation C. Simple Security Property and Polymorphism D. Simple Security Property and Polyinstantiation

Question 895

QUESTION NO: 890 The equation used to calculate the total number of symmetric keys (K) needed for a group of users (N) to communicate securely with each other is given by which of the following? A. K(N – 1)/ 2 B. N(K – 1)/ 2 C. K(N + 1)/ 2 D. N(N – 1)/ 2

Answer 895

D Explanation: The formula is: Total number of users multiplied by total number of users minus 1, the results are then divided by 2) When using symmetric algorithms, the sender and receiver use the same key for encryption and decryption functions. Each pair of users who want to exchange data using symmetric key encryption must have two instances of the same key. This means that if Dan and Iqqi want to communicate, both need to obtain a copy of the same key. If Dan also wants to communicate using symmetric encryption with Norm and Dave, he needs to have three separate keys, one for each friend. This might not sound like a big deal until Dan realizes that he may communicate with hundreds of people over a period of several months, and keeping track and using the correct key that corresponds to each specific receiver can become a daunting task. If ten people needed to communicate securely with each other using symmetric keys, then 45 keys would need to be kept track of. If 100 people were going to communicate, then 4,950 keys would be involved. The equation used to calculate the number of symmetric keys needed is N(N – 1)/ 2 = number of keys ISC CISSP Exam "Pass Any Exam. Any Time." - www.actualtests.com 848 The following answers are incorrect: K(N – 1)/ 2 N(K – 1)/ 2 K(N + 1)/ 2 The following reference(s) were/was used to create this question: Harris, Shon (2012-10-18).

Question 1009

QUESTION NO: 1004 For competitive reasons, the customers of a large shipping company called the "Integrated International Secure Shipping Containers Corporation" (IISSCC) like to keep private the various cargos that they ship. IISSCC uses a secure database system based on the Bell-LaPadula access control model to keep this information private. Different information in this database is classified at different levels. For example, the time and date a ship departs is labeled Unclassified, so customers can estimate when their cargos will arrive, but the contents of all shipping containers on the ship are labeled Top Secret to keep different shippers from viewing each other's cargos. An unscrupulous fruit shipper, the "Association of Private Fruit Exporters, Limited" (APFEL) wants to learn whether or not a competitor, the "Fruit Is Good Corporation" (FIGCO), is shipping pineapples on the ship "S.S. Cruise Pacific" (S.S. CP). APFEL can't simply read the top secret contents in the IISSCC database because of the access model. A smart APFEL worker, however, attempts to insert a false, unclassified record in the database that says that FIGCO is shipping pineapples on the S.S. CP, reasoning that if there is already a FIGCO-pineapple-SSCP record then the insertion attempt will fail. But the attempt does not fail, so APFEL can't be sure whether or not FIGCO is shipping pineapples on the S.S. CP. What is the name of the access control model property that prevented APFEL from reading FIGCO's cargo information? What is a secure database technique that could explain why, when the insertion attempt succeeded, APFEL was still unsure whether or not FIGCO was shipping pineapples? A. *-Property and Polymorphism B. Strong *-Property and Polyinstantiation C. Simple Security Property and Polymorphism D. Simple Security Property and Polyinstantiation

QUESTION NO: 1300 Researchers have recently developed a tool that imitates a 14 year old on the Internet. The authors developed a "Chatter Bot" that mimics conversation and treats the dissemination of personal information as the goal to determine if the other participant in the conversation is a pedophile. The tool engages people in conversation and uses artificial intelligence to check for inappropriate questions by the unsuspecting human. If the human types too many suggestive responses to the "artificial" 14 year old, the tool then notifies the police. From a legal perspective, what is the greatest legal challenge to the use of this tool? A. Violation of Privacy B. Enticement C. Entrapment D. Freedom of Speech
