CISSP Exam Preparation (Question 255)

(255) The U.S. Uniform Computer Information Transactions Act (UCITA) is a:

A. Model act that is intended to apply uniform legislation to electronic 
credit transactions

B. Model act that is intended to apply uniform legislation to software 
licensing

C. Model act that addresses electronic transactions conducted by financial 
institutions

D. Model act that addresses digital signatures

Explanation:

The National Commissioners on Uniform State Laws (NCUSL) voted to approve the Uniform Computers Information Transactions Act (UCITA) on July 29, 1999. This legislation, which will have to be enacted state-by-state, will greatly affect libraries access to and use of software packages. It also will keep in place the current licensing practices of software vendors. At the present time, shrink-wrap or click-wrap licenses limit rights that are normally granted under copyright law. Under Section 109 of the U.S. 1976 Copyright Act, the first sale provision permits the owner of a particular copy without the authority of the copyright owner, to sell or otherwise dispose of the possession of that copy. However, the software manufacturers use the term license in their transactions. As opposed to the word sale, the term license denotes that the software manufacturers are permitting users to use a copy of their softwarE . Thus, the software vendor still owns the softwarE . Until each state enacts the legislation, it is not clear if shrink-wrap licenses that restrict users rights under
copyright law are legally enforceablE . For clarification, shrink-wrap licenses physically accompany a disk while click-on and active clickwrap licenses are usually transmitted electronically. Sometimes, the term shrink-wrap is interpreted to mean both physical and electronic licenses to use softwarE . The focus of the UCITA legislation is not on the physical media, but on the information contained on the media.

CISSP Exam Preparation (Question 253)

(253) The theft of a laptop poses a threat to which tenet of the C.I.A. triad?

A. All of the above

B. Availability

C. Integrity

D. Confidentiality

because the user has lost the computing ability provided by the unit;
and integrity, because the data residing on and any telecommunications
from the portable are now suspect.

CISSP Exam Preparation (Question 252)

(252) seizure as established in the Fourth Amendment to the U.S. Constitution.
These restrictions are still, essentially, more severe than those on private
citizens, who are not agents of a government entity. Thus, internal
investigators in an organization or private investigators are not subject to
the same restrictions as government officials. Private individuals are not
normally held to the same standards regarding search and seizure since
they are not conducting an unconstitutional government search.
However, there are certain exceptions where the Fourth Amendment

applies to private citizens if they act as agents of the government/police.
Which of the following is NOT one of these exceptions?

A. The private individual conducts a warrantless search of company
property for the company.
B. The private individual conducts a search that would require a search
warrant if conducted by a government entity.
C. The government is aware of the intent to search or is aware of a
search conducted by the private individual and does not object to
these actions.
D. The private individual performs the search to aid the government.

Explanation:
Since the private individual, say an employee of the company, conducts a search for evidence on property that is owned by the company and is not acting as an agent of the government, a warrantless search is permitted. The Fourth Amendment does not apply. For review, the Fourth Amendment guarantees: The right of the people to be secure in their persons, houses, papers,
and effects, against unreasonable searches and seizures, shall not be violated, and no Warrants shall issue, but upon probable cause, supported by oath or affirmation, and particularly describing the place to be searched, and the persons or things to be seized. The exigent circumstances doctrine provides an exception to these guarantees if destruction of evidence is imminent. Then, a warrantless search and seizure of evidence can be conducted if there is probable cause to suspect criminal activity. The other answers describe exceptions where the private individual is subject to the
Fourth Amendment guarantees.

CISSP Exam Preparation (Question 251)

(251) Which of the following is NOT a form of computer/network surveillance?

A. Use of CCTV cameras

B. Use of network sniffers

C. Keyboard monitoring

D. Review of audit logs

Explanation:

CCTV cameras fall under the category of physical surveillance.
Answers a and b are forms of active surveillance. These types of surveillance require an organizational policy informing the employees that the surveillance is being conducted. Additionally, warning banners describing the surveillance at log-on to a computer or network should be prominently displayed. These banners usually state that by logging on, the user acknowledges the warning and agrees to the monitoring. Answer “Review of audit logs” is a passive form of computer/network surveillance.

C. Improper dissemination and use of identifiable personal data

D. Recordkeeping whose very existence is secret

Seek to gain unauthorized access to the resources of the Internet
Destroy the integrity of computer-based information
Disrupt the intended use of the Internet
Waste resources such as people, capacity and computers through such actions
Compromise the privacy of users

CISSP Exam Preparation (Question 249)

(249) Which of the following alternatives should NOT be used by law enforcement to gain access to a password?

A. Contacting the developer of the software for information to gain access to the computer or network through a back door

B. Compelling the suspect to provide the password

C. Data manipulation and trial procedures applied to the original version of the system hard disk

D. Using password cracker software

Explanation:

The original disk of a computer involved in a criminal investigation should not be used for any experimental purposes since data may be modified or destroyed. Any operations should be conducted on a copy of the system disk. However, the other answers are the preferred methods of gaining access to a password-protected system.
Interestingly, in answer b, there is legal precedent to order a suspect to provide the password of a computer that is in the custody of law enforcement.

CISSP Exam Preparation (Question 237)

(237) The European Union Electronic Signature Directive of January, 2000, defines an advanced electronic signature. This signature must meet all of the following requirements except that:

A. It must be created using means that are generally accessible and available.

B. It must be uniquely linked to the signatory.

C. It must be linked to the data to which it relates in such a manner that any subsequent change of the data is detectable.

D. It must be capable of identifying the signatory.

Explanation:
The Directive requires that the means be maintained under the sole control of the signatory. This requirement is a particularly difficult one to achieve. One approach is to use different tokens or smart cards for the different transactions involved. The other answers are typical
characteristics of digital signatures that can be implemented with public key cryptography.
