Which of the ISO/IEC 2700X standards (as well as their clauses and subclauses) reflect the requirements related to the information security risk management process. For example, in the context of information security of a banking organization?


The ISO/IEC 27000 series of standards is specifically designed to help organizations manage their information security processes. The series is extensive, but the standards most pertinent to information security risk management are ISO/IEC 27001 and ISO/IEC 27005. Here's how they break down:

ISO/IEC 27001: Information Security Management Systems (ISMS) - Requirements
ISO/IEC 27001 is the central standard for establishing, implementing, maintaining, and improving an Information Security Management System. It contains explicit requirements for risk management in the context of information security:

Clause 4: Context of the Organization
Understand the organization and its context.
Understanding the needs and expectations of interested parties.
Determining the scope of the ISMS.
ISMS and its processes.
Clause 6: Planning
6.1 Actions to address risks and opportunities
6.1.1 General – requires planning to manage risks.
6.1.2 Information security risk assessment – involves identifying and assessing information security risks.
6.1.3 Information security risk treatment – involves selecting risk treatment options.
6.2 Information Security Objectives and Planning to Achieve Them
Clause 8: Operation
8.2 Information security risk assessment
8.3 Information security risk treatment
ISO/IEC 27005: Information Security Risk Management
ISO/IEC 27005 provides guidance on risk management in the context of information security, offering a more detailed look at risk management beyond the requirements listed in ISO/IEC 27001:

Clause 7: Information Security Risk Management Process
7.1 Context Establishment
Understanding the organization's environment and boundaries for risk management.
7.2 Risk Assessment
Risk identification
Risk analysis
Risk evaluation
7.3 Risk Treatment
Selecting and implementing measures.
7.4 Risk Acceptance
Acceptance criteria and decision-making.
7.5 Risk Communication
7.6 Risk Monitoring and Review
Ensuring that risks and their treatments are actively managed.
Clauses 9 and 10:
Provide additional guidance on maintaining and adapting the risk management process.
ISO/IEC 27002: Code of Practice for Information Security Controls
While ISO/IEC 27002 does not specify risk management processes, it supports ISO/IEC 27001 with guidelines and best practices for implementing specific controls. This can be beneficial in risk treatment selection when aligning with ISO/IEC 27001's requirements.

Implementation in a Banking Context
For a banking organization, particularly sensitive and regulated, integrating these standards involves developing a detailed ISMS tailored to their unique environment. This involves aligning the risk management process with regulatory requirements from entities like the Basel Committee on Banking Supervision and ensuring that specific banking risks are appropriately addressed.

Overall, the combination of ISO/IEC 27001's high-level framework requirements and ISO/IEC 27005's deeper dive into the risk management process provides a robust foundation for securing banking information systems against risks.
