Cyber Defence and Security Research Laboratory (CyDeS)

Cyber Defence and Security Research Laboratory (CyDeS) was founded on April 15, 2014, by the METU Informatics Institute, a research authority with immense knowledge and practice experience in the field of information technology, and the Comodo Gorup, Inc., one of the leading companies in the world in the field of information technology and security certification, aiming to conduct research and development activities and bring together universities and industry resources. As an interdisciplinary center, CyDeS is expected to form necessary cooperation between existing cyber defence and security experience of the university and the sectorial resources.
