Confidentiality

Which areas of a file cannot be used by steganography to hide data?

In areas that contain the content data itself

In the file header fields that describe the file

In data that is used to describe the content or structure of the actual data

In the directory structure of the file system

Which of these is NOT a characteristic of a secure hash algorithm?

Collisions should be rare.

A message cannot be produced from a predefined hash.

The results of a hash function should not be reversed.

The hash should always be the same fixed size.

Diffusion

Confusion

Integrity

Chaos

Which of these is the strongest symmetric cryptographic algorithm?

Alice’s private key

Bob’s public key

Alice’s public key

Bob’s private key

Egor wanted to use a digital signature. Which of the following benefits will the digital signature not provide?

Verify the sender

Prove the integrity of the message

Verify the receiver

Enforce nonrepudiation

Illya was asked to recommend the most secure asymmetric cryptographic algorithm to his supervisor. Which of the following did he choose?

SHA-2

ME-312

BTC-2

RSA

At a staff meeting one of the technicians suggested that the enterprise protect its new web server by hiding it and not telling anyone where it is located. Iosif raised his hand and said that security through obscurity was a poor idea. Why did he say that?

It is an unproven approach and has never been tested.

It would be too costly to have one isolated server by itself.

It would be essentially impossible to keep its location a secret from everyone

It depends too heavily upon non-repudiation in order for it to succeed.

What is a characteristic of the Trusted Platform Module (TPM)?

It provides cryptographic services in hardware instead of software

It allows the user to boot a corrupted disk and repair it

It is available only on Windows computers running BitLocker

It includes a pseudorandom number generator (PRNG)

Which of these has an onboard key generator and key storage facility, as well as accelerated symmetric and asymmetric encryption, and can back up sensitive material in encrypted form?

Trusted Platform Module (TPM)

Hardware Security Module (HSM)

Self-encrypting hard disk drives (SED)

Encrypted hardware-based USB devices
