ISO 27001 is a standard certification that specifies a framework for Information Security Management System (ISMS). It includes a set of policies and procedures required to manage information security risks.
2. Why do organizations need ISO 27001 certification?
The ISO 27001 certification helps protect the reputation from security threats and improves the organization’s security posture. It proves to stakeholders, regulatory bodies, customers, and governments that the organization is secure and trustworthy.
3. Explain the principles of ISO 27001.
The principles of ISO 27001 are a methodology used to reduce the risks to the confidentiality, integrity, and availability of information. The following are the principles:
4. Define ISMS.
ISMS stands for Information Security Management System, a set of security policies and procedures maintained to handle the organization’s confidential information.
5. Define Annex A.
Annex A is a catalog of security control used to identify, assess, manage, and respond to information security risks. It includes 93 controls categorized into 4 sets together to form a framework.
6. List out the Annex A controls.
The following are the security controls of Annex A, which includes 4 controls:
7. What are the basic principles of Information security?
The basic principles of information security are Confidentiality, Integrity, and Availability, and each element is designed to provide the fundamental principles of data security.
8. Mention the difference between ISO 27001 and ISO 27002.
ISO 27001 certification includes 93 security controls categorized into 4 sets. ISO 27002 is not a certification but operates as a guide to the security controls defined in ISO 27001.
9. What are the objectives of Information Security Policies?
The Information Security Policies come under Annex A.5 security control. The main objective of Information Security Policies is to ensure that the security policies are developed and maintained per the organization’s requirements.
10. What is the difference between vulnerability and threat?
A vulnerability is a security weakness or flaw that can compromise the entire security posture, procedures, policies, and controls. It creates an attack surface and allows cyber attackers to exploit the information.
A threat is a malicious activity intended to steal or modify the data in the system. It takes advantage of a vulnerability and allows attackers to access confidential information.
11. Mention a list of six security policies defined by ISO 27001.
12. What is a risk assessment defined in ISO 27001?
The ISO 27001 Risk Assessment is a process of identifying, analyzing, and evaluating the potential risks in the organization. Organizations define a Risk Assessment Framework (RAF) to define and prioritize the risks to the organization’s information security posture.
13. What are the steps to implement a risk management process?
The following are the steps to implement the risk management process:
14. List some threats that can impact an organization’s security framework.
15. What is an ISO 27001 Statement of Applicability?
The State of Applicability is a standard document that defines the ISO 27001 controls and policies that the organization is implementing. It serves as a roadmap to the ISMS that covers technical, legal, and physical controls associated with the information risk processes.
16. Define Root Cause Analysis (RCA) in ISO 27001.
Root Cause Analysis (RCA) is a process of implementing analysis tools and techniques to identify the actual root cause for security non-conformity. It helps to prevent the recurrence of security issues in the future.
17. What are the phases of the Incident response lifecycle?
The NIST incident response lifecycle consists of four phases. They are as follows:
18. What are the steps to implement ISO 27001?
The following are the steps to implement ISO 27001:
19. What are the two major security policies?
The two major security policies are as follows:
20. What is ISO 27001 Gap Analysis?
The ISO 27001 Gap Analysis is an assessment that offers a high-level overview of the organization’s security posture. It serves as a guide to assess and compare the organization’s information security with the latest requirements.
