Control Catalogues in Cybersecurity: A Comparative Analysis of ISO/IEC 27002:2022 and NIST SP 800-53

Control catalogues are essential tools in cybersecurity, offering comprehensive lists of security controls designed to protect information assets. Two major control catalogues discussed in the lectures are ISO/IEC 27002:2022 and NIST SP 800-53. Each document provides detailed guidance on implementing security measures to address various threats and vulnerabilities.

ISO/IEC 27002:2022 (3rd Edition)

Overview

• Title: ISO/IEC 27002:2022
• Content: Provides guidelines for information security management practices, specifying a set of controls for managing information security risks.
• Structure: Divided into four main categories of controls:
  1. Organizational Controls
  2. People Controls
  3. Physical Controls
  4. Technological Controls

Key Features

• Annex A: Describes the purpose and use of control attributes, providing an example of how these attributes can be applied.
• Control Attributes: Attributes such as information security properties (confidentiality, integrity, availability), control types (preventive, detective, corrective), and others are used to classify and manage controls effectively.

Important Sections to Read

• Annex A: Understanding control attributes and their application.
• Chapters 5, 6, and 7 of Taylor et al.: Offer a tutorial guide to a wide range of security controls, particularly Chapter 5 (pp. 112–132) on procedural and people controls.

NIST SP 800-53 (Rev. 5)

Overview

• Title: NIST Special Publication 800-53 (Rev. 5): Security and Privacy Controls for Information Systems and Organizations
• Content: Provides a catalogue of security and privacy controls for federal information systems and organizations, aiming to protect organizational operations, assets, and individuals.
• Structure: Organized into 20 control families, each focusing on different aspects of security and privacy, such as access control, audit and accountability, and incident response.

Key Features

• Control Families: Each control family includes specific controls tailored to address particular security and privacy needs.
• Flexibility: Designed to be adaptable to various types of organizations and environments, making it a versatile tool for cybersecurity management.

Important Sections to Read

• Chapter 2 (pp. 7–15): Provides an overview of the controls in the catalogue.
• Control Families: Browse through the document to get an idea of the breadth and depth of controls described.

Comparative Analysis

Approach

• ISO/IEC 27002:2022: Takes a broad, organizational approach, categorizing controls into four main groups and emphasizing the integration of security practices into overall business processes.
• NIST SP 800-53 (Rev. 5): More detailed and technical, with 20 control families that cover specific areas of security and privacy, offering granular controls for federal information systems.

Attributes and Classification

• ISO/IEC 27002: Uses attributes like information security properties and control types to classify controls, making it easier to manage and select appropriate controls based on risk assessments.
• NIST SP 800-53: Each control family is comprehensive, addressing various aspects of security and privacy, allowing organizations to implement specific controls tailored to their needs.

Practical Application

Example 1: Implementing Access Controls

ISO/IEC 27002:

• Control: Privileged Access Rights
• Guidance: Establish authorization processes, define stringent authentication requirements, and regularly review privileged access.

NIST SP 800-53:

• Control Family: Access Control (AC)
• Specific Controls: AC-1 (Access Control Policy and Procedures), AC-2 (Account Management), AC-3 (Access Enforcement).

Example 2: Managing Technical Vulnerabilities

ISO/IEC 27002:

• Control: Management of Technical Vulnerabilities
• Guidance: Maintain a detailed inventory of systems, conduct routine penetration testing, and implement updates promptly.

NIST SP 800-53:

• Control Family: System and Communications Protection (SC)
• Specific Controls: SC-7 (Boundary Protection), SC-8 (Transmission Confidentiality and Integrity), SC-12 (Cryptographic Key Establishment and Management).
