In times when data and information are traded like commodities, protecting them is essential. One way to do this is to implement information security management based on the ISO/IEC 2700x series of information security standards. This is an international family of standards for IT security and information security in private, public or non-profit organizations. Based on ISO 27001, an information security management system (ISMS) can be implemented, which organizations and public authorities can set up, operate and have certified for their own protection.

Standards for information security: The ISO 2700X family of standards

The individual standards for information security in the ISO 2700x series deal with diverse topics in the area of information security. For example, the international standard specifies ISO 27001. An information security management system (ISMS), ISO 27701 a data protection management system, ISO 27017 provides guidance on information security measures for cloud computing, and ISO 27005 provides guidelines for information security risk management.

Companies in all industries can benefit from the systematically structured approach of these standards for information security. It enables confidential data to be protected against loss and misuse, and helps to reliably identify and reduce (potential) threats. The approach helps to ensure the availability of corporate IT systems, thus contributing to the optimization of business processes, IT and process costs, and the minimization of business and liability risks.

 

Certification is a competitive advantage

Certification to ISO 27001, for example by DQS, requires a certain amount of preparation and effort. However, the company provides documented proof that it complies with information security requirements and implements measures to protect sensitive company data. This is a clear competitive advantage.

 

Ten ISO standards on information security that you should be familiar with

The list below provides an informative overview of the current status of the ISO 2700x series of standards in information security. All standards are available for purchase from the ISO website.

ISO 27001 - Requirements for information security management systems

In times when data and information are traded like rare commodities, their protection is essential. An optimal basis for the effective implementation of a holistic security strategy is provided by a well-structured information security management system (ISMS) in accordance with the standard ISO 27001. This is an internationally recognized standard for information security in private, public or non-profit organizations, which not only covers the aspects of IT security.

An ISO 27001 ISMS defines requirements, rules, and methods for ensuring the security of information that requires protection in organizations. The ISO standard provides a model for establishing, implementing, monitoring, and improving the level of protection. The aim is to identify potential risks for the company, analyze them and make them controllable through appropriate measures. ISO 27001 formulates the requirements for such a management system, which are audited as part of an external certification process .

You can achieve this with the standard:

  • Making the security of sensitive information an integral part of corporate processes.
  • Preventive safeguarding of the protection goals confidentiality, availability and integrity of information
  • Maintaining business continuity through continuous improvement of the security level
  • Sensitization of employees and significantly increased security awareness at all levels of the company
  • Building trust with interested parties
  • Establishment of an effective risk management process

Information technology - Security techniques - Information security controls for the energy utility industry

It helps you secure your electronic process control systems used to control and monitor the production, transmission, storage, and distribution of electrical energy, gas, oil, and heat, and to control related supporting processes.

What you can do with the standard:

  • Systematically ensure the protection goals of confidentiality, availability, integrity of information.
  • Continuously improve the security level and resistance to unauthorized access
  • Achieve greater security of action and legal certainty, improve adherence to relevant compliance requirements
  • Increase security awareness among employees and managers
  • Achieve a high level of trust and loyalty among all interested parties
  • Demonstrate recognized proof of the effectiveness of your security measures to the authorities, such as the German Federal Network Agency (BNetzA)

ISO 27006 - Requirements for certification bodies

ISO 27006 is aimed at bodies such as DQS that perform certifications of information security management systems. The ISO 27006 accreditation standard describes the requirements that certification bodies must follow when assessing their clients' management systems to ISO 27001 for certification.

ISO/IEC 27006:2015
Information technology - Security techniques — Requirements for bodies providing audit and certification of information security management systems

This includes e.g. the proof of specified audit efforts or specifications on the qualifications of auditors. The accreditation processes outlined in the standard guarantee that ISO 27001 certificates issued by accredited certification bodies have international validity.

What you can achieve with this standard:

  • Uniform criteria for certification, surveillance, and recertification audit procedures
  • Ensure the validity of ISO 27001 certificates
  • Ensure minimum requirements for audit effort and qualification of personnel calculating and performing certification procedures

ISO 27002 - Guidance on information security controls
