Security Firm Spokesperson: We have installed a very secure access

Question

Security Firm Spokesperson:  We have installed a very secure access system for our firms' computer network, so your data will be safe with us. Our computers can be accessed only from our headquarters, and access to the network requires multiple biometric signatures that even the most skilled hacker cannot duplicate.

Hacker:  Every computer security system that has publicly claimed to be impenetrable has eventually been compromised. Once the challenge has been put forth publicly, it is only a matter of time before someone gains unauthorized access to the system.

Consider each of the following statements. Choose the statement that is most strongly supported by the Security Firm Spokesperson's statements and the statement that is most strongly supported by the Hacker's statements.

Statement supporting spokesperson (since he says that system is safe and biometrics is difficult to replicate by a hacker): A hacker cannot penetrate the security system by copying an employee's fingerprints and other biometric signatures

Statement supporting hacker (anything which was claimed to be impenetrable was compromised, it's just the availability of sufficient amount of time):Given enough time, the Security Firm's network will be accessed without authorization.

Security Firm Spokesperson:  Our computers requires multiple biometric signatures which can't be duplicated.

The spokes person claim is based upon the unique identification signatures (fingerprints/retinal scan etc.) which can't be copied at any cost when the signatures to be used is with multiple people at the same time.

The key element here is "BIO METRIC SYSTEM"

Hacker:  it is only a matter of time before someone gains unauthorized access to the system.

Hacker claim that any account or computer system is accessible if the hacker is given enough time to forge through system.

The key element here is "TIME"

WE have to check which of the option states the above stated highlights as the focal point of the statement.

1)  A hacker will eventually gain access by taking advantage of a human error in the management of the system.  (Neither Time nor biometric is present in the statement, can't be used as the strengthening point for any of the spokesperson or hacker) (Incorrect)

2)  A hacker cannot penetrate the security system by copying an employee's fingerprints and other biometric signatures. (Biometric is the main highlight here, which was stated in spokesperson's claim) (so, it's spokesperson's strengthening point)

3)  Every security system will eventually be comprised by a hacker.  (Neither Time nor biometric is present in the statement, can't be used as the strengthening point for any of the spokesperson or hacker) (Incorrect)

4)  The multiple biometric signatures required to access the system make the system prohibitively expensive for most of the Security Firm's clients.  (Biometric is present but the focal point of whole statement is cost not biometric) (Incorrect)

5)  Given enough time, the Security Firm's network will be accessed without authorization. (Time is the main highlight here, which was stated in hacker's claim) (so, it's hacker's strengthening point)

6)  The security software cannot be penetrated using any current method of hacking.  (Neither Time nor biometric is present in the statement, can't be used as the strengthening point for any of the spokesperson or hacker) (Incorrect)

So Spokesperson's Strengthening point is 2nd statement. 
And Hacker's Strengthening Point is 5th statement.

"Given enough time, the Security Firm's network will be accessed without authorization." Hi  Bunuel , can you help me with this Q. Here are we assuming that security firm eventually make their claim public? If that's a case then, " Every security system will eventually be comprised by a hacker." can also be true.

Hi gullyboy09,

Good instinct, and you're right on the first half: the spokesperson  did  make the claim public. "Your data will be safe with us" plus "even the most skilled hacker cannot duplicate" is exactly the kind of public impenetrability claim the Hacker is talking about. So yes, the Hacker's logic absolutely applies to  this  firm - which is why  Option 5  ("Given enough time, the Security Firm's network will be accessed without authorization") is supported.

Where Option 3 breaks: the scope word.

Look closely at what the Hacker actually claims:

- "Every computer security system  that has publicly claimed to be impenetrable  has eventually been compromised."

The Hacker's conclusion is limited to systems that  publicly claim  impenetrability. It says nothing about systems that make no such claim.

Now read Option 3: " Every  security system will eventually be compromised by a hacker." That drops the qualifier and covers  all  security systems - including quiet ones that never issued a public challenge. The Hacker never supports that broad statement. Option 5 stays inside the Hacker's scope (this one firm, which did make the claim); Option 3 reaches past it.

So the public-claim assumption you spotted is exactly what makes  5  work - but it's also the very thing that  3  ignores.

Quick test to lock it in:

Suppose the Hacker had instead said  "Every security system, whether it claims impenetrability or not, gets compromised."  Now Option 3 would be supported. See how one phrase changes which statement fits? When a choice widens the scope beyond what the speaker actually said, it overreaches - and the tighter, in-scope choice wins.

Answer: Column 1 (Spokesperson) = A hacker cannot penetrate the security system by copying an employee's fingerprints and other biometric signatures.; Column 2 (Hacker) = Given enough time, the Security Firm's network will be accessed without authorization.
