ISO/IEC 15408-1:2009 Information technology — Security techniques — Evaluation criteria for IT security —
Part 1: Introduction and general model
ISO/IEC 15408-1:2009 is a standard that provides guidance on how to evaluate the security of information technology systems. In this article, we will be looking at the introduction and general model of ISO/IEC 15408-1, and discussing how it can help you evaluate the security of your own IT systems.
ISO/IEC 15408-2 Information security, cybersecurity and privacy protection — Evaluation criteria for IT security — Part 2: Security functional components
ISO/IEC 15408-2 offers a model for evaluating the effectiveness of IT security management practices. The model provides a systematic way to assess and compare the effectiveness of different security management functions. Including risk assessment, management, incident response and prevention, and security auditing and monitoring.
The evaluation criteria in ISO/IEC 15408-2 can be used to measure the effectiveness of individual security management practices or as part of an overall risk management strategy. Thus, the evaluation criteria can also be used to identify areas where improvements can be made in an organization’s IT security management system.
ISO/IEC 15408-2 is intended for use by organizations that need to assess their own IT security risks and determine how best to address them. In addition, this standard can be used by certification bodies to certify competency in information security management.
ISO/IEC 15408-3:2008 Information technology — Security techniques — Evaluation criteria for IT security — Part 3: Security assurance components
ISO/IEC 15408-3:2008 is an international standard that defines the evaluation criteria for IT security. Part 3 of the standard deals with security assurance components.
The security assurance components are the processes and procedures used to ensure that the IT security solutions meet the intended requirements. Moreover, The goal of security assurance is to ensure that the risks associated with IT systems are manageable, and that these risks do not exceed acceptable levels.
Security assurance can be achieved through a number of different methods, including compliance assessments, technical evaluations, and human factors assessments. In addition, Each method has its own strengths and weaknesses. And it is important to choose the method that best suits the particular situation.
Therefore, ISO/IEC 15408-3:2008 is a valuable resource for organizations looking to improve their IT security posture. It provides a comprehensive model for evaluating IT security solutions, and it provides guidance on how to achieve security assurance objectives.
ISO/IEC 15408-4 Information security, cybersecurity and privacy protection — Evaluation criteria for IT security — Part 4: Framework for the specification of evaluation methods and activities
ISO/IEC 15408-4 provides a framework for the specification of evaluation methods and activities to assess the effectiveness of IT security. Evaluation criteria can be used to evaluate the effectiveness of security controls and risk management practices.
ISO/IEC 15408-4 includes five chapters:
Chapter 1 provides an introduction to ISO/IEC 15408-4, including a general model for information security, cybersecurity and privacy protection.
Chapter 2 discusses the concepts of evaluation and assessment.
And Chapter 3 introduces the concept of risk management, discussing concepts such as risk assessment, risk identification, and risk mitigation.
Chapter 4 describes evaluation techniques for IT security controls, including penetration testing and malware analysis.
Also, Chapter 5 provides a model for the specification of evaluation methods and activities. This model can be used to develop evaluation criteria for IT security controls.
ISO/IEC 15408-5 Information security, cyber security and privacy protection — Evaluation criteria for IT security — Part 5: Pre-defined packages of security requirements
ISO/IEC 15408-5 Information security, cyber security and privacy protection — Evaluation criteria for IT security — Part 5: Predefined packages of security requirements
So, ISO/IEC 15408-5 is a set of evaluation criteria that provides a framework to help organizations evaluate the effectiveness of IT security measures. This document outlines seven predefined packages of security requirements, known as Security Profiles.
Organizations can use Security Profiles to assess the effectiveness of their existing IT security measures, as well as to identify areas where improvements are needed. Security Profiles can also be used to create a baseline for measuring the progress of an organization’s IT security program.
In fact, Security Profiles are based on the principle of least privilege, which states that users should have only the permissions necessary to perform their assigned tasks. Users with elevated privileges may be able to exploit vulnerabilities in systems and access sensitive data.
Organizations should consult ISO/IEC 15408-5 when implementing new or revised IT security measures. This document can also help organizations evaluate the effectiveness of their current IT security program.
