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
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

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

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
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

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?

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
