Women in Security: Building a Female InfoSec Community in Korea, Japan, and Taiwan

S. Kang, A. Nakajima, and H. Yen

Black Hat USA 2019, Las Vegas, NV, USA, August 2019.

The information security industry has historically been a male-dominated field, and today, unfortunately, this situation has not changed much. Indeed, the survey conducted by Frost & Sullivan in 2017 concluded that women represented only 11% of the current information security workforce. While more women are expected to join the information security industry to reach new levels of innovation, still, it is difficult to increase their number because women face many obstacles, such as stereotype bias. One way to bridge this gap is a female community, which can support and motivate women, and produce more role models. In this talk, we will introduce three representative Asian female communities, Power of XX, CTF for GIRLS, and HITCON GIRLS, which were established in Korea, Japan, and Taiwan, respectively. We will first explain how we build and maintain each female community and then go into the details of how we tackled various challenges, such as building a sustainable community and attracting and retaining new members.
