Re: CISSP "sample" questions


@shahzadafridi wrote:
Then it is part of policy so why "D" option. I have doubts on background statement

Exactly what @rslade wanted you to think about.  One can make a case for any of the four answers, but one of these things (read some of the comments) is less "good" than the rest.  Since Rob gave you the reference, you can go to the source and understand why the particular answer was chosen.

 

What Rob is doing here is similar to what we know about the (ISC)² test development process.  The difference being that Rob follows up by explaining the thought process behind the answer, whereas (ISC)²'s next step is to use the question on actual exams, with zero-weighting until the answer is "proven" good, bad or indifferent.

 

Rob is doing a wonderful thing here.  It is not about a building a "brain dump" of actual questions...   It's learning to get inside the head of the test-writers, understanding how/why the questions were written and selecting the answer that matches their way of thinking.  In the case of CISSP, that person would be someone with many years of cross-functional IT security experience that keeps up with current trends and generally holds a position where they are making/leading decisions as part of the company's management.  This is an important skill not just for the CISSP exam, but for communicating with people in general. 

 

Understanding that this skill exists and learning to use it contributed more to my passing  than any of the time I spent with study materials.  It has also served me well as a go-between between management and techies and also between techies of different disciplines.

Re: CISSP "sample" questions

@rslade @denbesten 

The last time, I attended an item writing workshop, we not only had to provide the reference but we also had to write a justification for the correct answer and why the wrong answers were wrong.   So a lot of thought goes into questions.

 

So I appreciate what Rob is doing and his dedication to assisting, although, the Subject of the thread could be changed as the format and rigour should be the same with all exams.

Re: CISSP "sample" questions

If you are some credit card company or any company that deals with PII of customers i think the mission statement must include to protect this data in rest and transit. Policy statement as a high level objective will not include the technical specification off course.

P.S just giving a thought for discussion otherwise i agree with your explanation

Re: CISSP "sample" questions

In data processing systems, the value analysis should be performed in terms of which three properties?

a. Profit, loss, ROI
b. Intentional, accidental, natural disaster
c. Assets, personnel, services provided
d. Availability, integrity, confidentiality

 


Answer: d.
Reference: Information Systems Security; Fites & Kratz; Thompson Press; 1996; pg 54.

 

OK, in a sense this is kind of a trick question, for a couple of reasons.  But it does have a point.  The point is, choose the answer with the greatest breadth and application that does answer the question.


Answer a - incorrect - it's right, but applies only to business management.
Answer b - incorrect - it's right, but applies directly to threat analysis.
Answer c - incorrect - it's right, but considered mostly in business impact analysis.

(There is a myth that says that if you see the CIA triad [confidentiality, integrity, availability] as an answer on any question on the CISSP exam, that is the correct answer.  In fact, a friend, knowing of the myth, once specifically wrote a question so that CIA was wrong ...  :-)

Re: CISSP "sample" questions

Which of the following techniques MOST clearly indicates whether specific risk reduction controls should be implemented?

a. Threat and vulnerability analysis.
b. Risk evaluation.
c. ALE calculation.
d. Countermeasure cost/benefit analysis.


Answer: d.


Reference: Computer Security Handbook (3rd edition) Hutt, Boswirth, Hoyt; pg 3.3.

 

A fairly simple question: it should be fairly obvious.  Again, the principle here is to choose the answer that most broadly answers the question.  All the answers are important parts of security and risk assessment, but:
Answer a - this analysis does not address whether specific countermeasures should be implemented.
Answer b - risk evaluation studies existing risks but doesn’t address whether specific countermeasures should be implemented.
Answer c - ALE is the calculation of loss expectancy but does not address whether specific countermeasures should be implemented.
Answer d - correct - in a countermeasures cost/benefit analysis, the annualized cost of safeguards is compared with the expected cost of loss.

 

Oh, one more point: if you saw this question on an exam these days, it should be reworded slightly.  Acronyms in questions are now supposed to be spelled out in full.

Re: CISSP "sample" questions

Prior to implementation, a complete description of an operational security issue should specify threat, vulnerability, and

a. safeguard.
b. asset.
c. exposure.
d. control.


Answer: b.

(Reference: Fitzgerald, Jerry, Internal Controls for Computerized Systems, 1978, pg 7)

 

This isn't really a type of question, as such, it's just one that a surprising number of people get wrong.  We tend to concentrate on "problems" and forget what it is that we are trying to protect.  Don't get that (or any other kind) of tunnel vision.

 

Which, I suppose, is as good a segue as any to another point.  Remember that the CISSP is a general, and even international, certification.  When presented with a question, don't pick an answer that is specifically suited to your job or company: pick the answer that is most suited to security in general.

Re: CISSP "sample" questions

What step can a company take to reduce the risk of its employees violating software copyright laws?

a. Remove copy programs from personal computers.
b. Install application licensing meters to prevent an excess of users for each license.
c. Establish a company policy prohibiting the unauthorized duplicating of software.
d. Prohibit the use of software on multiple computers.

 

 

Answer: c.

 

This is another question that lots and lots of people get wrong.  But, by this time, you should get it right because it illustrates points already made.
Answer a - wrong - Well, it's possible, and might work, but it's not really practical, is it?  Copying is a basic function of computers: users have a need to copy files.  Besides, even if you took it off, people could put it back.
Answer b - wrong - A meter notes and possibly alerts you to the use of software beyond the number of licensed copies.  It may or may not prevent copying.  It would help, but it is not a complete solution.
Answer c - correct - The policy doesn’t prevent copying, but does reduce the liability risk if employees are caught making illegal copies.  (And that's the real risk in violating copyright, yes?)  And it means you can fire them if they do.  (If there's no policy against it, what did they do that was wrong?)
Answer d - wrong - It's kind of impractical because more than one user may need to use the program.  I mean, really ...

 

Oh, and remember that earlier point about the management answer being the right one?

Re: CISSP "sample" questions

Who is ultimately responsible to ensure that information is categorized and that specific protective measures are taken?

a. Security Officer
b. Senior Management
c. Data Owner
d. Custodian


Answer: b.
Reference: Commonsense Computer Security; Martin Smith; 1993; pg 63.

 

This is possibly as close to a "trick" question that you'll get on the exam.  If you are just skimming the question, and the answers, the fact that the data owner is generally responsible for assigning data classification is going to jump out at you.  Again, read the whole question.  The key word here is "ultimately."  "Ultimately," senior management is responsible for everything.  The security officer may play some role in data classification, but unless you work in a MAC (Mandatory Access Control) environment won't be the one making individual decisions.  And the custodian just acts on behalf of the owner.

Re: CISSP "sample" questions

@rslade I agree with your answer but as a seasoned item writer, I would really object to this question being on an exam as it is a trick.  Sr. Management have the ultimate responsibility, however the Data Owner is the only person who truly understands the value of the data....and if they get it wrong, it doesn't matter what Sr. Management does in terms of data value, etc.

 

Also think that you would find the stats on a question like this would be poor.

 

Just my nickel

I don't disagree with you.

At the same time, I think that, as an example, it does emphasize two important
points:
1) the importance of the "management" answer, and
2) read the question carefully!
