PECB ISO-IEC-27001-Lead-Implementer Exam With Confidence Using Practice Dumps

In the context of management reviews, the term “suitability” refers to whether the Information Security Management System (ISMS) continues to align with the organization’s objectives, strategic direction, and purpose. Therefore, Option C is the correct and verified answer.

ISO/IEC 27001:2022 Clause 9.3 – Management review requires top management to review the ISMS at planned intervals to ensure its continuing suitability, adequacy, and effectiveness. While these three terms are related, they have distinct meanings:

Suitability focuses on alignment — whether the ISMS remains appropriate for the organization’s business objectives, context, and strategic direction.

Adequacy considers whether the ISMS is sufficient in scope and resources.

Effectiveness evaluates whether the ISMS achieves its intended outcomes.

Clause 9.3.2 explicitly states that management review inputs shall include information on:

changes in external and internal issues (Clause 4.1),

needs and expectations of interested parties (Clause 4.2),

achievement of information security objectives (Clause 6.2).

These inputs are used to determine whether the ISMS still fits the organization’s goals and priorities, which is the essence of suitability.

Option A is incorrect because alignment with certification standards is a compliance matter, not the definition of suitability.

Option B is incorrect because being well-designed and embedded relates more to adequacy and effectiveness, not suitability.

The correct and verified answer is B. Technological, because the identified risk—unrestricted write access to production source code and development tools—must be managed through technical enforcement mechanisms, not solely by people or organizational measures.

The scenario describes a failure to restrict access to critical production systems, allowing a junior developer to modify source code without authorization. This is a classic access control and privilege management issue that requires technological controls such as role-based access control (RBAC), privileged access management, repository permissions, and segregation of environments.

ISO/IEC 27001:2022 Annex A categorizes controls into organizational, people, physical, and technological groups. The controls relevant to this scenario fall squarely under technological controls, including:

A.8.2 – Privileged access rightsRequires restriction and management of elevated access to prevent unauthorized or excessive privileges.

A.8.3 – Information access restrictionEnsures access to information and systems is limited in accordance with business requirements.

A.8.4 – Access to source codeExplicitly requires that access to source code is restricted, controlled, and monitored.

A.8.32 – Change managementEnsures that changes to production systems are authorized, tested, and approved.

While people controls (such as training or awareness) and organizational controls (such as policies) are supportive, they are insufficient on their own. Without technical enforcement, policies cannot prevent unauthorized access in practice.

ISO/IEC 27001:2022 emphasizes defense-in-depth, where technological controls enforce rules automatically, reducing reliance on human behavior alone.

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.”
