    Section B — Multi-Task Question (Syllabus Area C)

    Scenario: "SecureBank" is a multinational bank. It recently implemented a distributed, immutable digital ledger to record all inter-bank transfers. The IT department also enforced a new policy requiring all staff to change their passwords every 30 days. Last month, the bank's compliance team detected a criminal attempting to move illicit funds through dozens of complex international wire transfers to obscure their origin. Yesterday, the bank's servers were overwhelmed by a massive flood of fake internet traffic, taking their website offline.

    Evaluate the scenario and complete the following 4 tasks:
    Task 1: Identify the technology used for the inter-bank transfers.
    Task 2: Classify the password policy control (General IT vs Application).
    Task 3: Identify the stage of money laundering detected by the compliance team.
    Task 4: Identify the type of cyber-attack that took the website offline.

    Which of the following combinations correctly answers Tasks 1 to 4?

    Answer options:

    A.

    1: Big Data, 2: Application control, 3: Placement, 4: Ransomware

    B.

    1: Artificial Intelligence, 2: General IT control, 3: Integration, 4: Phishing

    C.

    1: Blockchain, 2: General IT control, 3: Layering, 4: DDoS

    D.

    1: Blockchain, 2: Application control, 3: Layering, 4: Malware

    How to approach this question

    Task 1: Distributed ledger = Blockchain. Task 2: System-wide password rules = General IT control. Task 3: Complex transfers to hide money = Layering. Task 4: Flooding traffic to crash a site = DDoS.

    Full Answer

    C.1: Blockchain, 2: General IT control, 3: Layering, 4: DDoS✓ Correct
    Task 1: Blockchain is a distributed, immutable ledger. Task 2: General IT controls apply to the whole IT environment (like passwords), whereas application controls apply to specific transactions. Task 3: Layering involves complex transactions to distance the money from its illegal source. Task 4: A Distributed Denial of Service (DDoS) attack overwhelms a server with traffic.

    Common mistakes

    Confusing General IT controls with Application controls, or confusing Layering with Placement.
