ISC copyright Security Professional (copyright) Sample Questions (Q151-Q156):

NEW QUESTION # 151
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. Simple Security Property and Polyinstantiation
  • C. Simple Security Property and Polymorphism
  • D. Strong *-Property and Polyinstantiation

Answer: B

Explanation:
The Simple Security Property states that a subject at a given clearance may not
read an object at a higher classification, so unclassified APFEL could not read FIGCO's top secret
cargo information.
Polyinstantiation permits a database to have two records that are identical except for their
classifications (i.e., the primary key includes the classification). Thus, APFEL's new unclassified
record did not collide with the real, top secret record, so APFEL was not able to learn about FIGs
pineapples.
The following answers are incorrect:
*-Property and Polymorphism
The *-property states that a subject at a given clearance must not write to any object at a lower
classification, which is irrelevant here because APFEL was trying to read data with a higher
classification.
Polymorphism is a term that can refer to, among other things, viruses that can change their code
to better hide from anti-virus programs or to objects of different types in an object-oriented
program that are related by a common superclass and can, therefore, respond to a common set of
methods in different ways. That's also irrelevant to this question.
Strong *-Property and Polyinstantiation
Half-right. The strong *-property limits a subject of a given clearance to writing only to objects with
a matching classification. APFEL's attempt to insert an unclassified record was consistent with this
property, but that has nothing to do with preventing APFEL from reading top secret information.
Simple Security Property and Polymorphism
Also half-right. See above for why Polymorphism is wrong.

NEW QUESTION # 152
Which of the following is best at defeating frequency analysis?

  • A. Substitution cipher
  • B. Transposition cipher
  • C. Ceasar Cipher
  • D. Polyalphabetic cipher

Answer: D

Explanation:
Simple substitution and transposition ciphers are vulnerable to attacks that perform frequency analysis.
In every language, there are words and patterns that are used more than others.
Some patterns common to a language can actually help attackers figure out the transformation between plaintext and ciphertext, which enables them to figure out the key that was used to perform the transformation. Polyalphabetic ciphers use different alphabets to defeat frequency analysis.
The ceasar cipher is a very simple substitution cipher that can be easily defeated and it does show repeating letters.
Out of list presented, it is the Polyalphabetic cipher that would provide the best protection against simple frequency analysis attacks.

NEW QUESTION # 153
Which one of the following factors is NOT one on which Authentication is based?

  • A. Type 2 Something you have, such as an ATM card or smart card
  • B. Type 3 Something you are (based upon one or more intrinsic physical or behavioral traits), such as a fingerprint or retina scan
  • C. Type 4 Something you are, such as a system administrator or security administrator
  • D. Type 1 Something you know, such as a PIN or password

Answer: C

Explanation:
Explanation/Reference:
Explanation:
Something you are, or authentication by characteristic, is based on a unique physical attribute, not what role you fulfill.
Incorrect Answers:
A: Something you know, or authentication by knowledge, can be a password, PIN, mother's maiden name, or the combination to a lock.
B: Something you have, or authentication by ownership, can be a key, swipe card, access card, or badge.
C: Something you are, or authentication by characteristic, is based on a unique physical attribute, referred to as biometrics.

NEW QUESTION # 154
Which of the following should exist in order to perform a security audit?

  • A. Neutrality of the auditor
  • B. Internal certified auditor
  • C. Industry framework to audit against
  • D. External (third-party) auditor

Answer: C

Explanation:
The thing that should exist in order to perform a security audit is an industry framework to audit against. A security audit is a systematic and independent examination of the security policies, procedures, controls, and practices of an organization, system, or network, to verify their compliance, effectiveness, and efficiency. A security audit requires an industry framework to audit against, which is a set of standards, guidelines, or best practices that define the security requirements, objectives, and criteria for the audit. An industry framework to audit against can help to establish the scope, methodology, and expectations of the security audit, as well as to measure and report the performance, gaps, and recommendations of the security audit. An industry framework to audit against can also help to ensure the consistency, reliability, and validity of the security audit, as well as to facilitate the comparison, benchmarking, and improvement of the security audit. Some examples of industry frameworks to audit against are ISO/IEC 27001, NIST SP 800-53, COBIT, or CIS Controls. An external (third-party) auditor, an internal certified auditor, and the neutrality of the auditor are not things that should exist in order to perform a security audit. These are some of the factors or attributes that may affect the quality, credibility, and independence of the security audit, but they are not prerequisites or conditions for the security audit. A security audit can be performed by an external or internal auditor, depending on the purpose, scope, and resources of the audit. A security audit can be performed by a certified or non-certified auditor, depending on the qualifications, skills, and experience of the auditor. A security audit should be performed by a neutral or unbiased auditor, to avoid any conflict of interest, influence, or pressure from the auditee or other parties.

NEW QUESTION # 155
Of the three types of alternate sites: hot, warm or cold, which is BEST described by the following facility description?
Configured and functional facility

Available with a few hours

Requires constant maintenance

Is expensive to maintain

  • A. Warm Site
  • B. Hot Site
  • C. Remote Site
  • D. Cold Site

Answer: B

Explanation:
Explanation/Reference:
Explanation:
A hot site is a facility that is leased or rented and is fully configured and ready to operate within a few hours. The only missing resources from a hot site are usually the data, which will be retrieved from a backup site, and the people who will be processing the data. The hot site would include computers, cables and peripherals.
Incorrect Answers:
B: A warm site is a leased or rented facility that is usually partially configured with some equipment, such as HVAC, and foundational infrastructure components, but not the actual computers. In other words, a warm site is usually a hot site without the expensive equipment such as communication equipment and servers.
C: A cold site is a leased or rented facility that supplies the basic environment, electrical wiring, air conditioning, plumbing, and flooring, but none of the equipment or additional services.
D: A remote site is just a site at a remote location. There are no specification on what equipment or services, if any, would be available at the remote location.
