ISO/IEC 27001

Introduction to ISO/IEC 27001 - Information Security Management System (ISMS)

ISO/IEC 27001 plays a pivotal role in the contemporary digital landscape, characterized by globalization, cloud computing, and the ever-growing necessity for robust data security. With the increasing reliance on various systems to collect, manage, and analyze information, companies face heightened risks related to information security. ISO/IEC 27001 was specifically designed to address these challenges by providing a framework for managing information security, mitigating risks, and preventing adverse outcomes.

As companies gather more information, they become more susceptible to threats, necessitating robust security measures to safeguard against accidental exposure and criminal activities. Each organization must tailor its implementation of ISO/IEC 27001 based on its unique infrastructure, information, products, and services, employing a risk-based approach to information security management.

At ITG, our certified ISO/IEC 27001 Consultants are committed to helping organizations efficiently prepare for and achieve ISO/IEC 27001 certification. With our expertise and strategic support, we ensure your Information Security Management goals and objectives are met effectively.

Gap Analysis

Gap Analysis is the first step in Process Improvement

ITG Consulting Services initiates each project with a comprehensive gap analysis (or gap audit) of a company's practices, aimed at gaining insights into the current operational state of the organization.

Our approach is founded on assessment practices and principles that engage through interviews, process review, workflow analysis, and examination of infrastructure and architectural requirements.

The importance of our strategic approach is to identify the capabilities and best practices of an organization with focus on strengths, and the identification of additional development needs that support an organization’s continued growth.

Frequently Asked Questions for ISO/IEC 27001

ISO/IEC 27001 is an information security standard, part of the ISO/IEC 27000 family of standards, of which the last version was published in 2022, with a few minor updates since then. It is published by the International Organization for Standardization (ISO/IEC) and the International Electrotechnical Commission (IEC) under the joint ISO/IEC subcommittee.

ISO/IEC 27001 specifies a management system that is intended to bring information security under management control and gives specific requirements. Organizations that meet the requirements may be certified by an accredited certification body following successful completion of an external and independent audit.

Who needs ISO/IEC 27001?

Nowadays, data theft, cybercrime and liability for privacy leaks are risks that all organizations need to factor in. Any business needs to think strategically about its information security needs, and how they relate to its own objectives, processes, size and structure. The ISO/IEC 27001 standard enables organizations to establish an information security management system and apply a risk management process that is adapted to their size and needs, and scale it as necessary as these factors evolve. While information technology (IT) is the industry with the largest number of ISO/IEC 27001- certified enterprises (almost a fifth of all valid certificates to ISO/IEC 27001 as per the ISO/IEC Survey 2021), the benefits of this standard have convinced companies across all economic sectors (all kinds of services and manufacturing as well as the primary sector; private, public and non-profit organizations). Companies that adopt the holistic approach described in ISO/IEC 27001 will make sure information security is built into organizational processes, information systems and management controls. They gain efficiency and often emerge as leaders within their industries.

How will ISO/IEC 27001 benefit my organization?

Resilience to cyber-attacks
Preparedness for new threats
Data integrity, confidentiality and availability
Security across all supports
Organization-wide protection
Cost savings

What are the three principles of information security in ISO/IEC 27001, also known as the CIA triad?

Confidentiality
Meaning: Only the right people can access the information held by the organization.
Risk example: Criminals get hold of your clients’ login details and sell them on the Darknet.
Information integrity
Meaning: Data that the organization uses to pursue its business or keeps safe for others is reliably stored and not erased or damaged.
Risk example: A staff member accidentally deletes a row in a file during processing.
Availability of data:
Meaning: The organization and its clients can access the information whenever it is necessary so that business purposes and customer expectations are satisfied.
Risk example: Your enterprise database goes offline because of server problems and insufficient backup.

An information security management system that meets the requirements of ISO/IEC 27001 preserves the confidentiality, integrity and availability of information by applying a risk management process and gives confidence to interested parties that risks are adequately managed.
