ISO-IEC-27005-Risk-Manager Exam Dumps : PECB Certified ISO/IEC 27005 Risk Manager

Aqualitative risk analysismethod uses nonnumerical categories such as low, medium, and high to describe the consequences and probability of risks. This method involves subjective judgment based on expertise, experience, and intuition rather than mathematical calculations. Qualitative methods are often used when it is challenging to obtain accurate numerical data, and they provide a general understanding of risks to prioritize them for further action. Option C is correct because the use of nonnumerical categories aligns with the qualitative risk analysis methodology. Option A (Quantitative) is incorrect as it involves numerical values and statistical methods, while Option B (Semi-quantitative) is a mix of qualitative and quantitative methods, usually involving ranges of numerical values.

Information security aims to protect information assets against threats and vulnerabilities that could lead to unauthorized access, disclosure, alteration, or destruction. By implementing effective security measures (such as access controls, encryption, and monitoring), an organization reduces the likelihood of vulnerabilities being exploited and mitigates the potential impact of risks. According to ISO/IEC 27005, risk management in information security includes identifying, assessing, and applying controls to reduce both the likelihood and impact of potential risks. Thus, option A is correct because it acknowledges the role of information security in reducing the impact of risks. Option B is incorrect because information security is a key component of risk management, and option C is incorrect because information security does not eliminate risks entirely; it mitigates their impact.

According to ISO/IEC 27000, information security is defined as the "preservation of confidentiality, integrity, and availability of information." This definition highlights the three core principles of information security:

Confidentialityensures that information is not disclosed to unauthorized individuals or systems.

Integrityensures the accuracy and completeness of information and its processing methods.

Availabilityensures that authorized users have access to information and associated assets when required.

This definition encompasses the protection of information in all forms and aligns with ISO/IEC 27005’s guidelines on managing information security risks. Therefore, option A is the correct answer. Options B and C are incorrect as they refer to more specific aspects or other areas of information management.
