Risk is typically assessed by combining risk impact and likelihood. Impact refers to the potential consequences if the risk event occurs, while likelihood refers to the probability of the event happening.

Threat level (A) and vulnerability score (C) are factors that contribute to likelihood, but likelihood itself is the direct input to risk calculation.

When establishing the risk management context for calculating risk, the formulas and methods for combining impact and likelihood must be consistent with the defined criteria. This ensures that the risk calculations are accurate and meaningful. If the formulas and methods are not consistent, the resulting risk scores may not accurately reflect the true level of risk.

While risk appetite and tolerance (A) are important for overall risk management, they don't directly dictate the formulas for calculation. KRIs and KPIs (C) are used for monitoring, not calculation.

Risk analysis helps quantify and articulate the potential impact of risks. While it can address all three areas (criticality of assets, lost productivity, and reputational damage), the most direct and quantifiable impact is typically on the criticality of I&T assets. Risk analysis can assess the impact of asset unavailability or compromise, making it easier to communicate the importance of those assets in terms of business operations.

Lost productivity and reputational damage can also be assessed, but they may involve more qualitative or indirect measures, making them somewhat harder to communicate precisely.

All of the options are relevant to risk response, but the cost of mitigating controls is a key factor in determining risk rankings. Organizations need to consider the cost-effectiveness of different risk responses. If the cost of mitigating a risk is prohibitively high, it may be ranked lower in priority compared to risks with more affordable mitigation options.

While the severity of a vulnerability (B) and the maturity of risk management processes (C) are important, they don't have the same direct impact on ranking as the cost of controls.

The most useful information to include in a risk report regarding control effectiveness is whether the controls are functioning as intended to reduce risk to acceptable levels. This directly addresses the core purpose of controls.

While alignment with standards (B) is important, it doesn't guarantee effectiveness. Confirmation of deficiencies by external audits (C) is relevant, but the primary focus is on whether controls are working.

Penetration testing is an example of an inductive method to gather information. Here's why:

Vulnerability Analysis: This typically involves a deductive approach where existing knowledge of vulnerabilities is applied to identify weaknesses in the system. It is more of a systematic analysis rather than an exploratory method.

Controls Gap Analysis: This is a deductive method where existing controls are evaluated against standards or benchmarks to identify gaps. It follows a structured approach based on predefined criteria.

Penetration Testing: This involves actively trying to exploit vulnerabilities in the system to discover new security weaknesses. It is an exploratory and inductive method, where testers simulate attacks to uncover security flaws that were not previously identified.

Penetration testing uses an inductive approach by exploring and testing the system in various ways to identify potential security gaps, making it the best example of an inductive method.

Cyber-Risiken betreffen Bedrohungen und Schwachstellen in IT-Systemen, die durch unbefugten Zugriff oder Missbrauch von Informationen entstehen. Dies schließt die unautorisierte Nutzung von Informationen ein.

Definition und Beispiele:

Cyber Risk: Risiken im Zusammenhang mit Cyberangriffen, Datenverlust und Informationsdiebstahl.

Unauthorized Use of Information: Ein Beispiel für ein Cyber-Risiko, bei dem unbefugte Personen Zugang zu vertraulichen Daten erhalten.

Schutzmaßnahmen:

Zugriffskontrollen: Authentifizierung und Autorisierung, um unbefugten Zugriff zu verhindern.

Sicherheitsüberwachung: Intrusion Detection Systems (IDS) und regelmäßige Sicherheitsüberprüfungen.

 Key Risk Indicators (KRIs):

KRIs are metrics used to signal the potential increase in risk exposures in various areas of an organization.

They provide early warnings that risk levels are changing, which allows for proactive management.

 Importance of Reliability:

The primary purpose of a KRI is to serve as an early warning system for potential risk events.

Reliability in prediction ensures that KRIs are effective in providing timely alerts before risks materialize.

 References:

ISA 315 (Revised 2019), Anlage 6 mentions the need for effective monitoring and identification of risk indicators to manage IT and other operational risks​​.

 Effectiveness of Risk Monitoring:

Continuous risk monitoring throughout the risk treatment planning process ensures that changes in the risk environment are detected early and addressed promptly.

It allows for real-time adjustments and improvements to the risk treatment plan.

 Phases of Risk Monitoring:

Before Treatment: Initial monitoring helps in understanding the baseline risk levels and identifying critical areas that need attention.

During Treatment: Ongoing monitoring ensures that the risk treatment measures are effective and any deviations are corrected timely.

After Treatment: Post-treatment monitoring verifies the long-term effectiveness of the risk responses and identifies any residual risks.

An example of a preventive control is data management checks on sensitive data processing procedures. Here’s why:

File Integrity Monitoring (FIM) on Personal Database Stores: FIM is a detective control. It monitors changes to files and alerts administrators when unauthorized modifications occur.

Air Conditioning Systems with Excess Capacity to Permit Failure of Certain Components: This is an example of a contingency plan or redundancy, designed to ensure availability but not directly related to preventing security incidents.

Data Management Checks on Sensitive Data Processing Procedures: These checks are designed to ensure that data is processed correctly and securely from the start, preventing errors and unauthorized changes to sensitive data. This is a preventive measure as it aims to prevent issues before they occur.

Therefore, data management checks on sensitive data processing procedures are a preventive control.
