 Purpose of Dataflow Diagrams:

Visual representation of how data moves through a system, including paths, processes, and storage locations.

 Why This is Correct:

Provides auditors with an overview of system processes and data handling practices.

Helps identify vulnerabilities or inefficiencies in data handling.

 Why Other Options Are Incorrect:

A. Order data hierarchically: Not the function of dataflow diagrams.

B. Highlight high-level data definitions: Focuses on detail, not flow.

D. Step-by-step details: Refers to process flows, not dataflows.

 References:

Dataflow diagrams are a standard tool referenced by EC-Council for mapping data handling processes during audits.

Comprehensive and Detailed Explanation (250–350 words) From Exact Extract from Chief Information Security Officer (CCISO) Documents:

The CCISO Body of Knowledge identifies persistent data (disk storage) and volatile data (memory, running processes, network connections) as the most common sources of forensic evidence.

Volatile data provides real-time insights but is lost on shutdown, while persistent data offers historical evidence. CCISO guidance stresses collecting volatile data first when feasible. Therefore, persistent and volatile data are the primary sources.

Comprehensive and Detailed Explanation (250–350 words)

===========

According to EC-Council CCISO documentation, ISO/IEC 27005 is the international standard that provides a formal framework for information security risk management.

ISO 27005 supports ISO 27001 by defining structured processes for risk identification, analysis, evaluation, treatment, monitoring, and communication. CCISO materials highlight ISO 27005 as the preferred risk management standard for organizations implementing or operating an ISMS.

An ISMS (Option A) is a management system, not a risk framework. COBIT (Option B) focuses on IT governance. NIST (Option C) is an organization that publishes frameworks, not a single risk standard.

Therefore, Option D is correct.

The next step after identifying potential solutions is to verify that the cost of mitigation is less than the risk. This ensures that mitigation strategies are cost-effective and align with the organization's risk appetite.

Cost-Risk Analysis:

Assess the financial and operational impact of proposed controls.

Ensure the cost of implementing controls is justified by the reduction in risk.

Sequence of Actions:

Only after verifying cost-effectiveness should the board of directors or vendors be engaged.

Risk metrics and vendor screening are subsequent activities based on selected solutions.

Risk-Based Decision Making:

Decisions prioritize solutions that provide optimal security without exceeding the value of the protected asset.

Cost-Benefit Analysis in Risk Management: Emphasizes evaluating cost-effectiveness as a critical step in risk mitigation.

Strategic Risk Reduction: Aligns mitigation efforts with organizational risk tolerances.
