Question 780

At Timberline Foods, the supply-chain assurance team is conducting a coordinated processing-plant assessment under requirements for food safety and secure logistics. Following the approved correction, auditors require proof that: A database uses a fixed initialization vector for repeated encryption of confidential records with a mode that requires unique nonces. Which result BEST demonstrates successful remediation?

  1. The device rotates to the new key and a verified authorized recovery procedure restores access successfully.
  2. A test harness confirms nonce uniqueness and altered ciphertext fails authentication.
  3. An unprivileged user cannot retrieve key material even when able to read ordinary application configuration.
  4. The client rejects an untrusted or wrong-name test certificate while accepting the legitimate service certificate.

Explanation

Correct Answer

B:

A test harness confirms nonce uniqueness and altered ciphertext fails authentication. The observable result demonstrates that the documented condition, A database uses a fixed initialization vector for repeated encryption of confidential records with a mode that requires unique nonces. has been addressed. The planned remediation is: Use an authenticated encryption scheme with safely generated non-reused nonces and protected keys. This is a stronger validation than a saved ticket or unverified claim by Timberline Foods.

Incorrect Answers

A:

The device rotates to the new key and a verified authorized recovery procedure restores access successfully. That observation would verify another scenario: An administrator rotates a disk-encryption key without preserving recovery policy and makes a test laptop unable to unlock its data. The corrective step for that other scenario is: Plan protected recovery escrow and test key lifecycle operations before enforcing device-wide rotation. But Timberline Foods is evaluating: A database uses a fixed initialization vector for repeated encryption of confidential records with a mode that requires unique nonces. The necessary outcome is: A test harness confirms nonce uniqueness and altered ciphertext fails authentication.

C:

An unprivileged user cannot retrieve key material even when able to read ordinary application configuration. That observation would verify another scenario: An application encrypts customer data but stores the encryption key in the same publicly readable configuration file. The corrective step for that other scenario is: Protect encryption keys with a managed key vault or HSM and enforce separate access and rotation controls. But Timberline Foods is evaluating: A database uses a fixed initialization vector for repeated encryption of confidential records with a mode that requires unique nonces. The necessary outcome is: A test harness confirms nonce uniqueness and altered ciphertext fails authentication.

D:

The client rejects an untrusted or wrong-name test certificate while accepting the legitimate service certificate. That observation would verify another scenario: A service presents a certificate signed by an unknown private CA and the client accepts it without checking trust and hostname. The corrective step for that other scenario is: Validate the full certificate chain, identity and validity interval against trusted roots rather than ignoring verification errors. But Timberline Foods is evaluating: A database uses a fixed initialization vector for repeated encryption of confidential records with a mode that requires unique nonces. The necessary outcome is: A test harness confirms nonce uniqueness and altered ciphertext fails authentication.

Question 781

At Juniper Media, the digital-platform security team is conducting a scoped content-delivery assessment under requirements for rights enforcement and safe media workflows. Assessors report the following documented condition: A payment service uses RSA encryption directly on large files rather than a modern hybrid-encryption design. Which action BEST addresses the documented security gap?

  1. Use an authenticated encryption scheme with safely generated non-reused nonces and protected keys.
  2. Plan protected recovery escrow and test key lifecycle operations before enforcing device-wide rotation.
  3. Use a random symmetric data-encryption key and protect it with an appropriate public-key or key-agreement mechanism.
  4. Use a memory-hard password hashing mechanism with unique salts and an appropriate work factor.

Explanation

Correct Answer

C:

Use a random symmetric data-encryption key and protect it with an appropriate public-key or key-agreement mechanism. This directly addresses the authorized assessment finding: A payment service uses RSA encryption directly on large files rather than a modern hybrid-encryption design. The Juniper Media team should verify the outcome rather than treat a configuration edit as proof. Acceptance evidence: Large files encrypt efficiently while only the intended recipient can recover the protected symmetric key.

Incorrect Answers

A:

Use an authenticated encryption scheme with safely generated non-reused nonces and protected keys. This is an appropriate control for a different issue: A database uses a fixed initialization vector for repeated encryption of confidential records with a mode that requires unique nonces. The Juniper Media finding instead concerns: A payment service uses RSA encryption directly on large files rather than a modern hybrid-encryption design. It does not demonstrate the required correction. The decisive test remains: Large files encrypt efficiently while only the intended recipient can recover the protected symmetric key.

D:

Use a memory-hard password hashing mechanism with unique salts and an appropriate work factor. This is an appropriate control for a different issue: A developer uses an unsalted fast checksum function to store user passwords in the authentication database. The Juniper Media finding instead concerns: A payment service uses RSA encryption directly on large files rather than a modern hybrid-encryption design. It does not demonstrate the required correction. The decisive test remains: Large files encrypt efficiently while only the intended recipient can recover the protected symmetric key.

Question 782

Question 784

At Meadowbrook Finance, the banking cyber assurance team is conducting a controlled financial-services security review under requirements for auditability and transaction integrity. An independent validation is requested for the original problem: A payment service uses RSA encryption directly on large files rather than a modern hybrid-encryption design. Which result BEST demonstrates successful remediation?

  1. Two identical test passwords produce different stored verifiers and no plaintext or fast unsalted hashes remain.
  2. Large files encrypt efficiently while only the intended recipient can recover the protected symmetric key.
  3. A protocol scan rejects obsolete handshakes while approved internal applications negotiate supported cipher suites.
  4. A test harness confirms nonce uniqueness and altered ciphertext fails authentication.

Question 785

At Eastshore Energy, the energy risk engineering team is conducting an authorized field-security exercise under requirements for remote equipment availability. The authorized review identifies: A company signs email using an expired certificate and assumes recipients will continue to trust the signature indefinitely. Which action BEST addresses the documented security gap?

  1. Renew the appropriate certificate and verify signature validity, chain, and trusted timestamp policy.
  2. Use an authenticated digital signature or message-authentication mechanism where sender authenticity is required.
  3. Use a random symmetric data-encryption key and protect it with an appropriate public-key or key-agreement mechanism.
  4. Protect encryption keys with a managed key vault or HSM and enforce separate access and rotation controls.

Explanation

Correct Answer

A:

Renew the appropriate certificate and verify signature validity, chain, and trusted timestamp policy. This directly addresses the authorized assessment finding: A company signs email using an expired certificate and assumes recipients will continue to trust the signature indefinitely. The Eastshore Energy team should verify the outcome rather than treat a configuration edit as proof. Acceptance evidence: A newly signed message validates under the current trust chain and invalid signatures are reported clearly.

Incorrect Answers

B:

Use an authenticated digital signature or message-authentication mechanism where sender authenticity is required. This is an appropriate control for a different issue: A file-transfer workflow hashes files with SHA-256 and concludes that this alone proves who sent the file. The Eastshore Energy finding instead concerns: A company signs email using an expired certificate and assumes recipients will continue to trust the signature indefinitely. It does not demonstrate the required correction. The decisive test remains: A newly signed message validates under the current trust chain and invalid signatures are reported clearly.
