Two types of papers will be accepted:

Full papers (max 14 pages without bibliography/appendices)
Such papers may describe original technical research with a solid foundation, such as formal analysis or experimental results, with acceptance determined mostly based on novelty and validation. Or they may describe case studies applying existing techniques or analysis methods in industrial settings, with acceptance determined mostly by the general applicability of techniques and the completeness of the technical presentation details.

Idea papers (max 8 pages with bibliography)
Such papers may crisply describe a novel idea that is both feasible and interesting, where the idea may range from a variant of an existing technique all the way to a vision for the future of security technology. Idea papers allow authors to introduce ideas to the field and get feedback, while allowing for later publication of complete, fully-developed results. Submissions will be judged primarily on novelty, excitement, and exposition, but feasibility is required, and acceptance will be unlikely without some basic, principled validation (e.g., extrapolation from limited experiments or simple formal analysis). In the proceedings, idea papers will clearly identified by means of the "Idea" tag in the title.

Posters
ESSoS will have a poster session to present ideas, discuss prototypes, and feature ongoing work. Authors of accepted papers and authors with evaluated artifacts are invited to submit a poster as well. Poster abstracts are limited to 1 page.

Approved Artifacts
Due to the secure software engineering focus, we expect the majority of papers to be based on an accompanying software artifact, data set, or similar. We strongly encourage the authors of accepted papers to submit such artifacts for evaluation. Artifact Evaluation will take place after accepted papers have been announced. Further information will be given closer to the paper-submission deadline. Submissions where the artifact evaluation committee can reproduce the software artifacts and evaluation will receive the “approved artifact” badge. Authors of approved artifacts are further given the opportunity to demo their artifact at the conference. In addition, the committee will select a best artifact to receive the Distinguished Artifact Award.
