PECB Updated ISO-IEC-27001-Lead-Implementer Exam Questions and Answers by arianna

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?

Scenario 9: CoreBit Systems

CoreBit Systems, with its headquarters m San Francisco, specializes in information and communication technology (ICT) solutions, its clientele primarily includes data communication enterprises and network operators. The company's core objective is to enable its clients a smooth transition into multi-service providers, aligning their operations with the complex demands of the digital landscape.

Recently. John, the internal auditor of CoreBit Systems, conducted an internal audit which uncovered nonconformities related to their monitoring procedures and system vulnerabilities, in response to the identified nonconformities. CoreBit Systems decided to employ a comprehensive problem-solving approach to solve these issues systematically. The method encompasses a team-oriented approach, aiming to identify, correct, and eliminate the root causes of issues. This approach involves several steps. First, establish a group of experts with deep knowledge of processes and controls. Next, break down the nonconformity into measurable components and implement interim containment measures. Then, identify potential root causes and select and verify permanent corrective actions. Finally, put those actions into practice, validate them, take steps to prevent recurrence, and recognize and acknowledge the team's efforts.

Following the analysis of the root cause of the nonconformities, CoreBit Systems's ISMS project manager. Julia, developed a list of potential actions to address the identified nonconformities. Julia carefully evaluated the list to ensure that each action would effectively eliminate the root cause of the respective nonconformity. While assessing potential corrective action for addressing a nonconformity, Julia identified the issue as significant and assessed a high likelihood of its reoccurrence Consequently, she chose to implement temporary corrective actions. Afterward. Julia combined all the nonconformities Into a single action plan and sought approval from the top management.

The submitted action plan was written as follows:

A new version of the access control policy will be established and new restrictions will be created to ensure that network access is effectively managed and monitored by the Information and Communication Technology (ICT) Department.

However. Julia's submitted action plan was not approved by top management The reason cited was that a general action plan meant to address all nonconformities was deemed unacceptable. Consequently, Julia revised the action plan and submitted separate ones for approval Unfortunately, Julia did not adhere to the organization's specified deadline for submission, resulting in a delay in the corrective action process, and notably, the revised action plans lacked a defined schedule for execution.

Julia, the ISMS project manager, developed a combined action plan for all nonconformities. However, it was rejected, revised, and resubmitted late—without defined execution schedules.

Question:

Did CoreBit Systems have a plan in place to implement permanent corrective action to address the identified nonconformities?
