Include them in the report rather than miss them in the risk assessment process
When might new types of risk surface during the risk identification process?
When a deeper level of investigation and evaluation of risk is conducted
Why is it important to reevaluate each documented risk?
To ensure accurate identification and assessment based on the current risk landscape
Study Notes
-
I&T-related failures, compromises, mistakes, or events can impact enterprise objectives and lead to direct and indirect losses.
-
Losses can include financial costs as well as reputational damage and inability to deliver key services or products.
-
Regular risk assessment is necessary to remain relevant, with annual updates for stable environments and new assessments for major changes.
-
Risk assessment includes ranking risks, grouping like risk types, and documenting existing controls.
-
Risk analysis is the process of estimating the frequency and magnitude of I&T-related risk scenarios.
-
Risk evaluation compares estimated risks against given risk criteria to determine significance and prioritize risks.
-
Risk scenario evaluation develops scenarios to describe potential risk events and estimate their impact.
-
Frequency analysis determines how often a particular risk scenario might occur during a specified period.
-
Methods for frequency analysis include historical data, models, professional judgment, or a combination of methods.
-
Validating frequency analysis results requires ensuring appropriate scope, reproducibility, insensitivity to data formatting, acknowledgement of assumptions and uncertainties, and credibility of critical assumptions.
-
Appropriate models, methods, and data should be fully documented and explained for frequency analysis.
-
In the absence of relevant historical data, other methods like fault-tree or event-tree analysis or mathematical or econometric models may be used for frequency analysis.
-
Third-party assurance reviews are analyses of enterprise processes, incidents, logs, and threat environments conducted by external entities, providing valuable information about vulnerabilities, control effectiveness, and risk.
-
Control Self-Assessment (CSA) and Control Risk Self-Assessment (CRSA) are methodologies used to review business objectives, risks, and internal controls. They are conducted by staff and management, ensuring employees are aware of business risks and conducting periodic reviews of controls.
-
A control owner is an individual to whom the enterprise has delegated the authority and accountability for making control decisions, responsible for ensuring the control is implemented effectively and efficiently.
-
Risk and control ownership are typically held by the same individual, as any modification or removal of a control impacts the associated risk.
-
IT may serve as custodians of controls, but ultimately, the business is responsible for accountability. Examples of enterprise-wide controls managed by IT include intrusion detection systems, email filters, data loss prevention platforms, and endpoint detection.
-
A Risk Register is a comprehensive list of identified, analyzed, and prioritized risks, providing detailed information on each risk.
-
Risk assessment evaluates the current control environment to determine its effectiveness and identify weaknesses. Controls are categorized based on intent: preventive, detective, corrective, and compensating.
-
Various sources are used to identify and assess the current state of controls, including audits, business continuity plans, control tests, incident reports, IT operations evaluations, logs, self-assessments, third-party reviews, and user feedback.
