*** Website https://vizsec.org/vizsec2021/ *** Poster Submission Deadline Extended. New Deadline: August 04, 2021 Event Date: October 27, 2021 We are cordially inviting you to participate in the poster session of the 18th IEEE Symposium on Visualization for Cyber Security (VizSec) 2021. VizSec brings together researchers and practitioners from academia, government, and industry to address the needs of the cybersecurity community through new and insightful visualization and analysis techniques. VizSec provides an excellent venue for fostering greater exchange and new collaborations on a broad range of security- and privacy-related topics. VizSec will take place on October 27, 2021, in conjunction with the 2021 IEEE VIS conference <http://ieeevis.org/>, giving VizSec authors and attendees enhanced access to IEEE VIS. VizSec program will be presented in an online format with virtual presentations. 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, penetration testing, and other related research topics. We are soliciting Poster Submissions. Poster submissions may showcase late-breaking results, work in progress, preliminary results, or visual representations relevant to the VizSec community. In line with the full conference, the presentation of posters will take place online. There will be 1-2 dedicated poster sessions in which poster authors can virtually meet and discuss their work with conference participants. An additional web presence of posters will replace the traditional physical installation of poster boards. More concrete details will follow soon. Awards There will be an award for Best Poster. This award will recognize authors’ efforts to clearly present their work to the audience. The award will be determined by anonymous judges and given to recipients at the end of the conference. Submissions Submissions must be formatted using the IEEE VGTC conference proceedings template that can be found at: https://tc.computer.org/vgtc/publications/conference/ Posters should be 2 page abstracts. Presenters are also encouraged to submit an accompanying video or other supplementary materials by following the IEEE VIS formatting guidelines. Reviews are single-blind, so authors may include names and affiliations in their submissions. VizSec uses the Precision Conference System (PCS) <https://new.precisionconference.com/vgtc> to handle the poster submissions and reviewing processes. Important Dates All deadlines are 5:00 PM PST.
