Answer:
ISO 27001 includes control objectives covering areas such as:
  • Information security policies
  • Security organization
  • Human resource security
  • Asset management
  • Access control
  • Cryptography
  • Physical and environmental security
  • Operations security
  • Communications security
  • Secure system acquisition, development, and maintenance
  • Supplier relationships

  • Meet regulatory requirements.
  • Obtain external certification through independent audits.


Question 7: What is ISO 27002?
Answer:
ISO 27002 is a supporting standard that provides detailed guidance on selecting, implementing, and managing information security controls. It explains how organizations can achieve the security objectives defined in ISO 27001.

  • Improve the effectiveness of cybersecurity programs.


Question 9: What is ISO 27701?
Answer:
ISO 27701 extends ISO 27001 and ISO 27002 by providing guidance for managing privacy information. It helps organizations establish a Privacy Information Management System (PIMS) to protect personal data.


Question 10: What is the main purpose of ISO 27701?
Answer:
ISO 27701 helps organizations:
  • Manage privacy risks.
  • Protect personal information.
  • Improve privacy governance.
  • Support compliance with privacy regulations.


Question 11: What is ISO 31000?
Answer:
ISO 31000 provides general guidelines for risk management. Unlike the other ISO standards, it is not limited to cybersecurity and can be applied to managing any type of organizational risk.


Question 12: How is ISO 31000 different from ISO 27001?
Answer:
  • ISO 27001 focuses specifically on information security management.
  • ISO 31000 provides a general framework for managing all types of risks across an organization.


Question 13: What is the difference between ISO 27001 and ISO 27002?
Answer:
  • ISO 27001 defines the security management framework and objectives.
  • ISO 27002 explains the security controls that help organizations achieve those objectives.
Think of it as:
  • ISO 27001 = What should be achieved
  • ISO 27002 = How to achieve it


Question 14: What is the difference between ISO 27001 and ISO 27701?
Answer:
Although their numbers are similar, they focus on different areas:
  • ISO 27001 → Information Security
  • ISO 27701 → Privacy Management
ISO 27701 expands the security framework established by ISO 27001 to include privacy controls.


Question 15: Why are ISO standards valuable to organizations?
Answer:
ISO standards help organizations:
  • Protect sensitive information.
  • Improve cybersecurity practices.
  • Manage privacy effectively.
  • Reduce organizational risks.
  • Meet legal and regulatory requirements.
  • Build customer confidence.
  • Demonstrate compliance through recognized certifications.


Key Points to Remember
ISO 27001
  • Information Security Management System (ISMS)
  • Defines security management requirements
  • Supports certification
ISO 27002
  • Security control implementation
  • Practical security guidance
  • Supports ISO 27001
ISO 27701
  • Privacy Information Management System (PIMS)
  • Extends ISO 27001
  • Focuses on privacy protection
ISO 31000
  • Enterprise risk management
  • Applies to all business risks
  • Not limited to cybersecurity


Important Exam Tip
⚠️ Don’t confuse these two standards:
  • ISO 27001 → Cybersecurity / Information Security
  • ISO 27701 → Privacy Management
Only one extra digit (7) changes the focus from security to privacy.


Memory Trick
Think of the progression:
  • 27001 → Manage Security
  • 27002 → Implement Security Controls
  • 27701 → Manage Privacy
  • 31000 → Manage Risk Everywhere
Easy mnemonic:
Security → Controls → Privacy → Risk
27001 → 27002 → 27701 → 31000
