VizSec provides an excellent venue for fostering greater exchange and new collaborations on a broad range of security- and privacy-related topics. VizSec will be held in Vancouver, Canada in conjunction with IEEE VIS, on Wednesday, October 23rd 2019. The purpose of VizSec is to explore effective and scalable visual interfaces for security domains such as network security, computer forensics, reverse engineering, insider threat detection, cryptography, privacy, user assisted attacks prevention, compliance management, wireless security, secure coding, and penetration testing. Poster submissions may showcase late-breaking results, work in progress, preliminary results, or visual representations relevant to the VizSec community. The poster program will be a great opportunity for the authors to interact with the attendees, potentially also through live demos, and solicit feedback. Accepted poster abstracts will be made available on this website. There will be an award for Best Poster. It comes with a $50 USD Amazon gift card thanks to our sponsor,Two Six Labs. The award will be determined by anonymous judges and given to recipients at the end of the conference.
