Clause 4.4 of ISO/IEC 27001:2022 states:
"The organization shall establish, implement, maintain and continually improve an information security management system, including the processes needed and their interactions, in accordance with the requirements of this document." This requirement highlights that an ISMS is not static; it must evolve continuously to adapt to new risks, technologies, and business changes. Options A, C, and D are not mentioned in the clause. The continual improvement cycle is central to ISO standards, aligning with thePlan-Do-Check-Act (PDCA)model.
Thus, the missing words are"continually improve."

ISO/IEC 27013 provides specific guidance on theintegration of ISO/IEC 27001 (Information Security Management) and ISO/IEC 20000-1 (IT Service Management). It offers practical advice for organizations seeking a unified management system approach. While ISO/IEC 27003 (A) provides guidance on ISMS implementation, it does not address integration. ISO 9001 (C) is the Quality Management Standard and can be integrated, but the specific standard designed forintegrating 27001 with ITSMis ISO/IEC 27013.
Therefore, the correct answer isB: ISO/IEC 27013, as it is explicitly published for this purpose.

Comprehensive and Detailed Explanation From Exact Extract ISO/IEC 27000 standards:
ISO/IEC 27000 defines:
* Risk analysis: "process to comprehend the nature of risk and to determine the level of risk" (Clause 3.58).
* Risk assessment: the overall process of risk identification, risk analysis, and risk evaluation.
* Risk evaluation: compares results of risk analysis against risk criteria to determine priority.
* Risk management: coordinated activities to direct and control an organization with regard to risk.
Therefore, the missing word in the given definition is"analysis".
This is important for ISMS implementation: organizations must understand the distinctions. Risk analysis is the core technical evaluation stage, while assessment is the broader process including evaluation, and management refers to the overall governance of risks.
Thus, the correct verified answer isB: Analysis.

ISO/IEC 27001 makes clear that the ISMS is intended to be tailored to the organization. The standard states: " This document also includes requirements for the assessment and treatment of information security risks tailored to the needs of the organization. The requirements set out in this document are generic and are intended to be applicable to all organizations regardless of type, size or nature." This means implementation is scaled based on each organization's risk, context, and needs, not a fixed one-size-fits-all set of activities or controls. Clause 6.1.3 further reinforces that control selection is flexible and risk-driven: " Organizations can design controls as required or identify them from any source," and "Annex A contains a list of possible information security controls... The information security controls listed in Annex A are not exhaustive and additional information security controls can be included if needed." Together, these extracts verify that the ISMS implementation is influenced by and scaled to the organization's needs and selected controls, not separated from management processes (A, D) nor mandated to include "all controls" (B).

Clause 6.1.1 (Planning) states:
"The organization shall plan:
d) actions to address these risks and opportunities; and
e) how to:
* integrate and implement the actions into its ISMS processes; and
* evaluate the effectiveness of these actions."
This confirms the missing words are"evaluate the effectiveness of". Communication (A), applying resources (B), and improving effectiveness (C) are important concepts elsewhere but not the direct requirement stated in this clause.
