Q21.

What is the objective of most copy protection technologies?

To allow unlimited use of protected software products

To control the way the protected software product is used

To promote software piracy

To make software products more affordable

Discuss

Answer: (b).To control the way the protected software product is used Explanation:The basic objective of most copy protection technologies is to control the way the protected software product is used.

Q22.

What are some ways in which copy protection technologies control the use of protected software products?

By making them time-limited

By making them non-transferable

By preventing duplication of the software product

All of the above

Discuss

Answer: (d).All of the above Explanation:Some products are time-limited, non-transferable, or cannot be duplicated, and the copy protection technology must enforce these restrictions.

Q23.

Why is attaining the objective of copy protection technologies difficult?

Because software piracy is too common

Because copy protection technologies are too expensive to implement

Because different software products have different license agreements

Because copy protection technologies are too easy to circumvent

Discuss

Answer: (d).Because copy protection technologies are too easy to circumvent Explanation:Copy protection technologies are difficult to attain because they are often easy to circumvent, allowing for the illegal copying and distribution of software products.

Q24.

Why is it difficult to create a truly secure protection technology?

Modern computers are "closed" in the sense that software runs on the CPU checked.

CPUs were designed to prevent anyone from gaining access to currently running code.

The separation of privileged/nonprivileged execution modes in CPUs is not effective.

There must be a secure trusted component in the system that is responsible for enforcing the protection.

Discuss

Answer: (d).There must be a secure trusted component in the system that is responsible for enforcing the protection. Explanation:It is difficult to create a truly secure protection technology because there must be a secure trusted component in the system that is responsible for enforcing the protection.

Q25.

What is the purpose of privileged/nonprivileged execution modes in CPUs?

To isolate the operating system kernel from programs.

To allow unrestricted access to currently running code.

To prevent users from installing any kind of hardware device on the system.

To prevent crackers from installing a kernel-level debugger such as SoftICE.

Discuss

Answer: (a).To isolate the operating system kernel from programs. Explanation:The purpose of privileged/nonprivileged execution modes in CPUs is to isolate the operating system kernel from programs.

Q26.

What is a class break?

A security technology or product that fails in a way that affects every user of that technology or product

A specific system that is under attack by a cracker

The ability of crackers to gain access to kernel-level components of an operating system

The susceptibility of modern CPUs to unauthorized access to currently running code

Discuss

Answer: (a).A security technology or product that fails in a way that affects every user of that technology or product Explanation:A class break can be defind as a security technology or product that fails in a way that affects every user of that technology or product.

Q27.

Why is it difficult to create uncrackable copy protection technology?

Because modern CPUs are “open” in the sense that software runs on the CPU unchecked

Because the kernels of most modern operating systems are completely accessible to end users

Because copy protection technologies are susceptible to class breaks

Because crackers can use kernel-level debuggers to observe and modify the kernel-level components of a system

Discuss

Answer: (c).Because copy protection technologies are susceptible to class breaks Explanation:Practically every copy protection technology is susceptible to class breaks, which makes it difficult to create uncrackable copy protection technology.

Q28.

What is a possible solution to the problem of creating secure copy protection technology?

Implementing a powerful copy protection by counting on the privileged/nonprivileged execution modes of modern CPUs

Creating significant architectural changes to the hardware

Rejecting any kind of kernel-level component installation on operating systems

None of the above

Discuss

Answer: (b).Creating significant architectural changes to the hardware Explanation:It is theoretically possible to create protection technologies that cannot be cracked at the software level by making significant architectural changes to the hardware.

Q29.

What is the main problem with copy protection technologies?

They are not robust enough

They can be easily defeated by a single cracker

They are not well-developed

They are not necessary

Discuss

Answer: (b).They can be easily defeated by a single cracker Explanation:A single cracker can invalidate the efforts of developers of copy protection technologies by simply figuring out a way to defeat the protection mechanism and publishing the results on the Internet.

Q30.

What is the main issue with malicious crackers?

They can easily defeat copy protection technologies

They can sell or distribute their work in mass quantities

They can deal with complex protection schemes

They have access to legal channels for obtaining programs

Discuss

Answer: (b).They can sell or distribute their work in mass quantities Explanation:The real problem with malicious crackers is when they sell or distribute their work in mass quantities.
