My paper Reasoning about Sequential Cyberattacks was accepted for FOSINT-SI 2019. I had the opportunity to present the paper at the conference last month in Vancouver, where I was also awarded "Best Paper".
You can check out my paper here.
I suffered a lot of heartbreak with this paper; it was either rejected for the most trivial of reasons (one reviewer rejected it because I didn't cite a particular work) or because it didn't seem like a good fit for the venue. I'm happy that it finally got accepted, and that it was also found good enough to be awarded "Best Paper". I must be doing something right in my PhD.
