Evaluate risks using a base ten logarithmic scale for consequences from under £100 to £1 million, and customize ISMS risk assessments to prevent clustering and misranking.

Quantify information security risk by multiplying likelihood and consequence on numerical scales to derive a score, prioritizing actions for data breaches, unauthorized access, and regulatory compliance under HIPAA and GDPR.

Clarify how risk acceptance criteria establish tolerance thresholds using a color coded risk matrix to classify risks as red, amber, or green, with governance for authorization and ongoing reassessment.

Apply a quantitative risk framework that combines financial loss with event frequency to classify risks into red, amber, and green zones, guiding immediate action, active mitigation, and prioritization.

Quantitative risk assessment uses concrete numbers and statistics to describe likelihood and consequences, enabling standardized risk comparison, prioritization, and resource allocation based on monetary terms like expected annual loss.

Identify, analyze, and evaluate information security risks within an integrated framework. Prioritize actions for risk owners by likelihood and impact, using event-based or asset-based approaches aligned to organizational risk management.

Explore asset-based and event-based risk assessment methodologies under ISO 27005:2022, mapping threats, vulnerabilities, and controls to primary business and supporting assets, with stakeholder ecosystems and risk scenarios.

Identify information security risks through an iterative process, using asset-based and event-based approaches to list threats to confidentiality, integrity, and availability, assign risk owners, and guide actions.

Identify and categorize organization assets into primary business assets and supporting assets, linking events, consequences, threats, and vulnerabilities to inform risk assessment and tailored controls under ISO 27005:2022.

Identify vulnerabilities and threats to assets using vulnerability analysis, audit reports, penetration testing techniques, and automated scans; classify threats as deliberate, accidental, or environmental.

Health Secure identifies IT asset risks, from EHR software vulnerabilities and weak cloud encryption to laptops' firewall gaps and data center downtime, and plans mitigations to protect sensitive data.

Identify risk owners by linking each identified risk to an accountable owner, establish authority and roles, and trigger updates when personnel or processes change.

Learn how to analyse information security risks using qualitative, quantitative, or semi-quantitative methods to assess likelihood and impact, prioritize controls, and decide whether to accept, transfer, avoid, or mitigate risks.

Assess consequences of information security risks under ISO 27005:2022 by analyzing risk scenarios, evaluating confidentiality, integrity, and availability impacts, reviewing controls, and guiding risk mitigation.

Apply a structured ISO 27005:2022 likelihood assessment to identify risk scenarios, evaluate controls, and quantify probability—using independent versus dependent events, triggers, and qualitative or quantitative methods.

Determine risk levels in ISO 27005:2022 through a process that combines likelihood and consequences to rank risks for treatment decisions, including EHR software and cloud servers.

Prioritize analyzed risks for risk treatment using risk criteria, producing a structured list of prioritized risks with scenarios and actions such as mitigating, transferring, accepting, or avoiding.

Adopt an event-based risk identification approach to map external and internal parties, assess strategic scenarios, and use asset-based methods and visual tools to prioritize risks and guide treatment.

determine risk treatment by prioritizing risks from assessment, selecting strategic ISO/IEC 27001:2022 Annex A controls, and applying cost-effective options to reduce, transfer, or accept risk.

Produce the statement of applicability by documenting risk-treatment controls and their justifications, reflecting implementation status to ensure transparency, accountability, and alignment with ISO/IEC 27001:2022.

Translate risk assessment results into an information security risk treatment plan by prioritizing risks and selecting ISO/IEC 27001:2022 controls to reduce likelihood, impact, and overall risk to acceptable levels.

Assess residual risks after risk treatment plans against acceptance criteria, balancing security with business needs and considering controls, timing, and stakeholder endorsements.

Learn how to plan, perform, and integrate ISO 27005:2022 information security risk assessments with budget cycles and business processes, and implement risk treatments to reduce residual risks to acceptable levels.
