CTF Challenge Remain:

CTF Overview

Continuous innovation in Internet technology development and applications has enhanced the quality of life and work efficiency but at the same time has created various new cyber security challenges. It only serves to fuel the demand for cyber security professionals. To cope with the challenges, the training of local cyber security practitioners and nurturing of new generations are indispensable.

For the new generation, Technology Education (TechEd) could foster and enhance their knowledge and interest in cyber security, train up their creative thinking, and learn skills such as cryptography, programming concept, network forensics to cope with new challenges.

For existing cyber security practitioners, regular update of latest trends and enhancement of cyber security skills can help organisations to reduce the risk and improve incident response capability.

In light of this, the Hong Kong Computer Emergency Response Team Coordination Centre (HKCERT) and the Hong Kong Productivity Council (HKPC) will jointly organise the “Hong Kong Cyber Security New Generation Capture the Flag (CTF) Challenge 2023” (The Contest) to strengthen the cyber security skills and awareness of the industry and students and encourage problem solving through teamwork, creative thinking and cyber security skills.

Workshops by cyber security experts will be organised to help the participants understand the format and type of questions of the Contest and get prepared for it.

Join now and get ready for the challenge!
