Cyber Risk Management

Cyber Risk Management is the process of identifying, assessing, and prioritising cybersecurity risks to your organisation and implementing controls to reduce them to an acceptable level. It translates technical threats into business risk — enabling leadership to make informed investment decisions.

Cyber risk quantification translates technical risks into financial terms — e.g. 'a ransomware attack has a 35% probability of costing RM 3–8 million in losses'. This helps boards and executives justify cybersecurity investment and prioritise controls based on actual business impact.

Cyber risk management is a foundational requirement across Malaysia's key regulatory frameworks:

• BNM RMiT (Risk Management in Technology): Requires financial institutions to implement a Technology Risk Management (TRM) framework, including regular risk assessments, threat modelling, and board-level risk reporting.
• ISO/IEC 27001: Mandates a risk-based approach to information security, requiring organisations to identify, assess, and treat information security risks as part of their ISMS.
• Cyber Security Act 2024 (Act 854): Imposes obligations on National Critical Information Infrastructure (NCII) entities to conduct risk assessments, implement controls, and report significant cyber incidents to NACSA.

A structured cyber risk management programme helps organisations meet these requirements, demonstrate due diligence to regulators, and prioritise security investments based on actual business risk.

A vulnerability assessment is a technical scan that identifies known weaknesses in systems, software, and configurations — it tells you what technical flaws exist in your environment.

A cyber risk assessment is broader and more strategic. It evaluates the likelihood and business impact of cyber threats materialising, taking into account your threat landscape, existing controls, asset criticality, and potential financial or operational consequences. Risk assessments produce a prioritised risk register that guides strategic security decisions and budget allocation.

In short: a vulnerability assessment tells you where the cracks are; a cyber risk assessment tells you which cracks matter most to your business and what it would cost if they were exploited.

Several industry-recognised frameworks are used for structured cyber risk quantification:

• FAIR (Factor Analysis of Information Risk): A quantitative model that expresses cyber risk in financial terms by analysing threat frequency, vulnerability, and loss magnitude. FAIR enables organisations to produce a monetary value for cyber risk, making it directly comparable to other business risks.
• NIST Risk Management Framework (RMF): A structured process for identifying, assessing, and managing information security and privacy risk, widely used by government agencies and enterprises globally.
• ISO/IEC 27005: Provides guidelines for information security risk management aligned with ISO 27001, covering risk identification, analysis, evaluation, treatment, and monitoring.
• OCTAVE (Operationally Critical Threat, Asset, and Vulnerability Evaluation): A risk-based strategic assessment and planning technique for security.

The choice of framework depends on the organisation's maturity, regulatory context, and whether qualitative or quantitative outputs are required for board reporting.

Expressing cyber risk in financial terms — often called cyber risk quantification (CRQ) — translates technical risk findings into the language of business: dollar values, probability ranges, and expected annual loss (EAL). This is increasingly essential for board-level reporting where cybersecurity competes for budget alongside other business risks.

Common approaches include:

• Expected Annual Loss (EAL): Calculated as the probability of a threat event multiplied by its estimated financial impact (direct losses, regulatory fines, reputational damage, operational downtime).
• Value at Risk (VaR): Borrowed from financial risk management, expressing the maximum likely loss at a given confidence level (e.g., "95% probability that a ransomware incident will cost less than RM 2 million").
• Cyber insurance benchmarking: Using market insurance rates as a proxy for risk severity to validate internal risk estimates.

Quantified cyber risk enables boards to make informed decisions on security investment, risk transfer (insurance), and residual risk acceptance — moving cybersecurity from an IT issue to a business governance priority.

Simply Data third-party risk monitoring uses passive external scanning and dark web intelligence to continuously assess your vendors — without requiring direct access to their systems. We monitor for: exposed assets (subdomains, open ports, vulnerable services) belonging to your vendors; leaked credentials of vendor employees who access your systems; dark web chatter and threat actor activity referencing your supply chain; and publicly disclosed vulnerabilities in software your vendors use.

Each vendor in scope receives a continuously updated risk score, with alerts triggered when material changes occur — such as a vendor suffering a data breach or a new critical CVE affecting their infrastructure. Reports are structured for both technical teams and executive stakeholders, supporting board-level third-party risk governance.

The number of vendors monitored depends on the scope of your engagement. Simply Data standard Cyber Risk Management engagements cover up to 20 critical third-party vendors — typically your top-tier suppliers with privileged access to your data, systems, or critical business processes. For organisations with extended supply chains, monitoring can be expanded to cover 50, 100, or more vendors.

We recommend a tiered approach: Tier 1 vendors (highest access and impact) receive continuous monitoring, while Tier 2 and Tier 3 vendors receive periodic assessment. This aligns with BNM RMiT requirements for financial institutions to maintain a comprehensive third-party risk management programme, and supports PDPA obligations for data processor management and oversight.
