ICTs for a Sustainable World #ICT4SDG
Lead study group on security (WTSA-12, Resolution 2)

As the lead study group for security, SG17 is responsible for the study of the appropriate core Questions on security. In addition, in consultation with other relevant study groups and in collaboration, where appropriate, with other standards bodies, Study Group has the responsibility to define and maintain the overall framework and to coordinate, assign (recognizing the mandates of the study groups) and prioritize the studies to be carried out by the study groups, and to ensure the preparation of consistent, complete and timely Recommendations.

Standardization Activities in SG 17, ITU-T SG’s and other SDO’s

The ICT Security Standards Roadmap presents a comprehensive view of standardization activities:


The Security Compendia presents a detailed view of standardization activities outputs:

The Security ManualSecurity in Telecommunications and Information Technology, is regularly updated (2015, 2012, 2009, 2006, 2004, 2003) :



  • SG 17 promotes workshops and seminars on Security and publishes guidance documents and presentations.
  • Security flyer

    Guidance on Security

    • Tutorial on writing safe and secure programs

    A list of suggestions has been prepared on how to avoid the most common pitfalls that make software less secure or less safe than it should be. It is addressed to software developers and covers the phases of software design, implementation, and testing. It focuses on network application programs, but many of the suggestions are equally valid for other kinds of software.

    • Security Guidance for ITU-T Recommendations

    ITU-T Study Group 17 has created a document "Security Guidance for ITU-T Recommendations" to provide guidance to authors and reviewers of ITU-T Recommendations to consistently address security considerations within their Recommendations. This document responds to WTSA-04 Resolution 50 which recognizes that converged legacy networks and IP networks are potentially more vulnerable to intrusion if adequate care is not taken in the security design and management and requires the ITU-T to evaluate existing and evolving new Recommendations, especially signalling and communications protocol Recommendations, with respect to their security considerations.

    Security Workshops 

    A number of workshops on security have been organized by SG17 including:

    • The ITU cybersecurity workshop on Global Cybersecurity Challenges – Collaborating for effective enhancement of cybersecurity in developing countries, was held in the afternoon of 8 September 2015 in conjunction with the overlapping ITU-D Study Group 2 and ITU-T Study Group 17 meetings.
      The workshop produced several important insights into the cybersecurity challenges faced by developing countries as well as best practices in meeting these challenges. The workshop demonstrated the spirit of good collaboration shared by ITU-T and ITU-D, and the workshop concluded in a commitment to expand this collaboration.
      - Presentations and relevant information are available at:
    • 15-16 September 2014 workshop entitled "ITU security workshop on ICT security standardization challenges for developing countries" was held at ITU Headquarters in Geneva, Switzerland. The workshop enhanced standardization competence by advising on the technical composition and best-practice of international ICT security standards. The event deepened collaboration in the security activities of ITU's standardization and development sectors (ITU-T and ITU-D), in addition benefiting ITU-T collaboration with other standards-setting organizations. The key topics of the workshop were: Cybersecurity, Data Protection, Trust Services and Cloud Computing including Big Data, with a focus on standardization and the role of ICTs in safeguarding critical infrastructure.

    • 30 August 2011 workshop entitled "Radioactivity safety and security threats protection and telemedical support for irradiated people" was held at ITU Headquarters in Geneva, Switzerland. This workshop has demonstrated prompt response by SG17 Question 9 to the Fukushima Daiichi incident in the domains of both safety and security through the in-force telebiometrics Recommendations ITU-T X.1081 and X.1082, etc. The workshop gave a good overview of the activities in telebiometrics standardization with applicability to e-Health and telemedicines.
      - Presentations and relevant information are available at
    • 6-7 December 2010 workshop entitled "Addressing security challenges on a global scale" was held at ITU Headquarters in Geneva, Switzerland. The workshop addressed the main challenges of the ICT/telecommunication security and how ITU and SDOs deal with these challenges. The workshop provided a good opportunity to overview new areas of security studies including Smart Grid and Cloud Computing.
