Exam ISO-IEC-27001-Lead-Implementer Topic 5 Question 6 Discussion

Actual exam question for PECB's ISO-IEC-27001-Lead-Implementer exam
Question #: 6
Topic #: 5
During a security audit, security analysts discover that an attacker has been repeatedly querying a black-box machine learning model to infer whether certain sensitive data points were part of the training dataset. By doing so, the attacker was able to determine if a specific individual's data was used in training. What threat does this attack represent?

Suggested Answer: C Vote an answer

A membership inference attack is when an attacker determines whether specific data was used in the training set of a machine learning model by analyzing the model's responses to queries. This is a major privacy threat for AI and ML systems, as referenced in information security and privacy controls for machine learning.
"Membership inference attacks allow adversaries to determine if certain records were part of the model's training data, which can lead to privacy violations."
- NIST SP 800-53 Rev. 5, ISO/IEC 27001:2022, Annex A 8.19
