Basic ISO 27001 Interview Questions 

The following basic Interview Questions on ISO 27001 will help you understand the concepts and definitions to gain a thorough understanding of ISO 27001:

1) Define what is ISO 27001. 

ISO 27001 is an international standard which helps organisations safeguard sensitive information by systematically addressing the possible threats from an Information Security standpoint. This standard outlines the requirements for creating, implementing, and managing an Information Security Management System (ISMS) within an organisation. 

2) What is the motive of ISO 27001? 

The primary motive of ISO 27001 is to keep the information and data of an organisation safe. It provides a framework for organisations to protect information assets, manage security risks, and comply with industry-specific regulations. The guidelines and rules under ISO 27001 help organisations to identify and fix security risks such as cyberattacks and data breaches.   

ISO 27001 protects the confidentiality and integrity of the information assets, which include sensitive data, systems, processes, and more. Getting certified in ISO 27001 Standards can help the organisation avoid potential threats, ultimately building a strong and secure operating organisational model. 

3) What do you mean by ISMS? 

Information Security Management System, also known as an ISMS, is a systematic approach that helps an organisation manage and protect its information assets. This approach includes various relevant policies, procedures, and technical measures designed to protect the organisation from threats like unauthorised access, data breaches, and cyberattacks.   

The goal of the ISMS is to promote a culture of responsibility and security within the organisation. ISMS helps employees at all levels, including the top management professionals, to stick to the guidelines, ensuring the organisation’s interests and industry regulations are in balance. 

4) What is Annex A of ISO 27001? 

Annex A of ISO 27001 is a detailed list of controls under the ISO 27001 Standard. Organisations can select the specific control or objective they want to achieve to protect and secure Information Security. There are 14 categories of controls, each addressing a specific aspect of Information Security.  

Annex A provides a detailed framework to select and implement controls based on the needs and interests of the organisation. Some of these controls include A.5 Information Security Policy, A.6 Organisation of Information Security, A.7 Human Resource Security, and more.   

5) What does Risk Assessment in ISO 27001 Standard mean? 

Risk Assessment in ISO 27001 is a fundamental process that helps in identifying, evaluating, and managing Information Security risks within an organisation. The goal of carrying out a Risk Assessment is to systematically identify significant threats, vulnerabilities, and the impact of security incidents on an organisation’s Information Security.  

This process also enables organisations to make informed decisions about how to protect their assets, allocate resources and ensure the availability of data. This process basically includes five steps: identification, evaluation, mitigation, acceptance, and monitoring.

8) What are the key principles of Information Security? 

The key principles of Information Security are commonly referred to as the CIA Triad, which represents the fundamental goals and objectives of effective Information Security management. The CIA Triad stands for Confidentiality, Integrity, and Availability. These core principles guide the organisation to establish robust practices and frameworks to protect its data and systems from various threats and risks. Here’s what the Triad comprises of:    

a) Confidentiality: This principle emphasises the protection of data from unauthorised access. It ensures that the data is accessed by those who are authorised to it or on a need-to-know basis. 

b) Integrity: The integrity principle makes sure that the data and system in the organisation are reliable and accurate. 

c) Availability: This principle focuses on the availability of information and data within an organisation.  

9) Differentiate between ISO 27001 and ISO 27002. 

ISO 27001 is an international standard which outlines the requirements for establishing and maintaining ISMS in an organisation. On the other hand, ISO 27002 is a guideline and best practice used to implement specific security controls within the ISMS. Following is a detailed differentiation between the two:  

10) Explain the role of Lead Auditor and Lead Implementer. 

The role of a Lead Auditor is to evaluate the organisation’s ISMS and make sure that it is aligned with the ISO 27001 Standard guidelines. Lead Auditor are external to an organisation and conduct an independent audit to assess and recommend areas of improvement. They are also responsible for planning audits, coordinating with audit teams, conducting assessments, and reporting findings to management.   

The role of a Lead Implementer is to deal with the internal aspects of ISO 27001 implementation in an organisation. A Lead Implementer is responsible for planning, implementing, and managing the ISMS compliance to meet the ISO 27001 Standards effectively.
