Information is one of the most valuable assets of companies and organizations today. Therefore, ensuring their security should be a priority for every enterprise, regardless of its size and sector. The best guarantee of information resource protection is the implementation of the ISO 27001 standard. What exactly is this standard, and why is it necessary for an organization?

The vast majority of companies have control mechanisms in place that allow them to assure their customers and business partners that they manage information security appropriately. However, we can only talk about truly working and conscious management of information assets when these controls are not accidental and are implemented with a real intention to protect information resources.

The implementation of the ISO/IEC 27001 standard guarantees that the organization has identified threats and implemented appropriate preventive measures to protect against security breaches.

What is ISO 27001?

The ISO 27001 standard is an international standard that standardizes information security management systems (ISMS). This standard specifies requirements for establishing, implementing, maintaining, and continuously improving an information security management system. Additionally, it contains guidelines for assessing and handling risks related to information security.

Firms and organizations that declare the implementation of the standard may be audited and subsequently certified as compliant with the standard. Meanwhile, an individual who completes the appropriate course can obtain a certificate confirming their knowledge of the standard and, for example, become a certified auditor in a company.

What is an information security management system?

An Information Security Management System (ISMS) is a systematic approach to managing sensitive company information so that it remains secure. It encompasses people, processes and IT systems.

What is ISO 27001 certification?

ISO 27001 certification is a confirmation that an organization meets the requirements of this standard and is fully compliant with it. A company can apply for certification by inviting an accredited certification body to conduct a certification audit, which, if successful, forms the basis for issuing the certification. The certificate is valid for three years.

Areas covered by ISO 27001 standard

Annex A of the standard distinguishes four areas that affect information security. These are:

  1. organizational security area,
  2. personnel security area,
  3. physical security area,
  4. technological security area.
