Mastering GRC with ISO 27001:2022 Risk Assessment Made Easy!

The video “Mastering GRC with ISO 27001:2022 Risk Assessment Made Easy!” provides a comprehensive, practical guide on performing Risk Assessments aligned with ISO 27001:2022. It focuses on information security governance, risk identification, analysis, evaluation, and treatment. The video emphasizes the importance of Risk Assessment in selecting appropriate controls (annexures) and offers detailed methodologies, examples, and documentation templates.

Main Financial Strategies, Market Analyses, or Business Trends Presented

Risk Management as a Business Enabler: Proper Risk Assessment helps organizations identify threats and vulnerabilities, allowing them to implement controls that protect assets and reduce potential financial, reputational, and operational losses.
Cost-Benefit Analysis in Risk Treatment: Decisions on Risk Treatment (mitigate, avoid, transfer, accept) should consider the cost of controls versus the potential impact, aligning Risk Management with business objectives and regulatory requirements.
Scenario-Based vs. Asset-Based Risk Assessment: Choosing the right Risk Assessment approach based on organizational size, complexity, security maturity, and threat landscape ensures efficient resource allocation and focused Risk Treatment.

Key Concepts and Methodologies

1. Terminology and Risk Calculation

Threat: An action that can harm an asset (e.g., hacker).
Vulnerability: Weakness in an asset that can be exploited (e.g., weak password).
Likelihood: Probability that a threat will exploit a vulnerability.
Impact: Consequences or damage resulting from a successful exploit.
Risk Formula: [ \text{Risk} = \text{Likelihood} \times \text{Impact} ]

2. Risk Management Process (4 Steps)

Risk Identification: Identify assets, threats, and vulnerabilities.
Risk Analysis: Calculate likelihood and impact (qualitative or quantitative).
Risk Evaluation: Compare risk levels against risk appetite/capacity to decide treatment.
Risk Treatment: Choose to accept, transfer, mitigate, or avoid risk.

3. Asset Classification

Primary Assets: Data, business processes, services (intangible).
Supporting Assets: Hardware, software, network, people (tangible).
Use Event-Based Risk Assessment focusing on services and their impact.

4. Types of Risk Assessment

Asset-Based Risk Assessment: Focus on individual assets, threats, and vulnerabilities. Suitable for smaller or compliance-driven environments.
Scenario-Based Risk Assessment (Event-Based): Focus on business processes and real-world incident scenarios. Suitable for complex environments with many interconnected systems or when external cyber threats exist.

5. Selecting Risk Assessment Approach

Consider the following factors:

Size and complexity of environment
Focus on specific assets or business processes
Nature of threats (cyber vs. physical)
Security maturity level
Compliance requirements (ISO 27001 alignment)

6. Likelihood and Impact Criteria

Likelihood: Defined using historical data and expert judgment. Scaled from rare (once every 5-10 years) to almost certain (multiple times per year).
Impact: Assessed across four dimensions:
- Operational disruption
- Financial loss
- Reputation damage
- Legal/regulatory consequences

Impact scores are averaged or weighted to determine overall impact level (minor to catastrophic).

7. Risk Treatment Types

Risk Avoidance: Eliminate the risk by discontinuing risky activities.
Risk Mitigation: Implement controls to reduce risk to acceptable levels (e.g., MFA, backups).
Risk Transfer: Shift risk to a third party (e.g., cyber insurance).
Risk Acceptance: Accept low risks where control cost exceeds benefit.

8. Documentation and Reporting

Risk Management Charter: Defines methodology, scope, objectives, risk appetite, and policies.
Risk Register: Records identified risks, likelihood, impact, controls, and residual risk.
Risk Assessment Report: Summarizes scope, context, risk scoring, and treatment plans.
Heat Map: Visual tool to present risk severity based on likelihood and impact.
Statement of Applicability (SOA): Justifies selected controls based on Risk Assessment.

Step-by-Step Guide to ISO 27001:2022 Risk Assessment (Summary)

Define Scope and Identify Assets: Tangible and intangible assets within the organizational boundary.
Identify Threats and Vulnerabilities: Determine potential threats and existing weaknesses.
Calculate Likelihood: Use historical data and expert judgment to assign probability scores.
Calculate Impact: Assess operational, financial, reputational, and legal consequences.
Compute Risk Score: Multiply likelihood by impact to get risk level.
Evaluate Risk Against Appetite: Decide if risk is acceptable or requires treatment.
Select Risk Treatment: Choose appropriate controls or actions based on evaluation.
