MTD 21 Workshop Chairs Welcome Message

It is our great pleasure to welcome you to the 2021 ACM Workshop on Moving Target Defense (MTD'21). The mission of MTD is provide a forum for researchers and practitioners in this area to exchange their novel ideas, findings, experiences, and lessons learned. The eighth MTD workshop has a special focus on the lessons learned from the past years of research in the area of moving target defenses, and the challenges and opportunities faced by the community moving forward. The call for papers attracted submissions from North America and Europe. Each submission received at least three reviews. Each submission was then discussed and carefully debated by the members of the program committee. After careful considerations, the program committee accepted three full technical papers. In an attempt to highlight the important lessons learned in the community so far, this year, we also organized five invited talks covering broad research efforts that capture important aspects of MTDs. These invited papers capture many years of experience in designing, building, evaluating, and transitioning MTD technologies to practice.
