GraMSec 2019: The Sixth International Workshop on Graphical Models for Security
Hoboken, NJ, USA - June 24, 2019

http://gramsec.uni.lu
Co-located with CSF 2019

*Submissions received by April 5 receive priority consideration*
*Papers not accepted for presentation a the workshop may be considered for publication in post-proceedings after major revision*

SCOPE
The use of graphical security models to represent and analyse the security of systems has gained an increasing research attention over the last two decades. Formal methods and computer security researchers, as well as security professionals from the industry and government, have proposed various graphical security models, metrics, and measurements. Graphical models are used to capture different security facets and address a range of challenges including security assessment, automated defence, secure services composition, security policy validation, and verification. For example, attack graphs, attack trees, attackñdefence trees, and attack countermeasure trees represent possible ways of attacking and defending a system while misuse cases and mal-activity diagrams capture threats and abusive behavior of users.

TOPICS
This year, we encourage excellent submissions related, but not restricted, to the following broad headings:
1. Graph representations: mathematical, conceptual, and implemented tools for describing and reasoning about security
2. Logical approaches: formal logical tools for representing and reasoning about graphs and their use as modeling tools in security
3. Machine learning: modeling and reasoning about the role of big data and machine learning in security operations
4. Networks in national security: terrorist networks, counter-terrorism networks; safety in national infrastructure (e.g., utilities and transportation)
5. Risk analysis and management: models of risk management in business and organizational architectures
6. Social networks: using and reasoning about social graphs, network analysis, network protocols, social mapping, sociometry.
Preference will be given to papers likely to stimulate high-quality debate at the Workshop.

SUBMISSION GUIDELINES
We solicit two types of submissions:
- Regular papers (up to 18 pages, excluding the bibliography and well-marked appendices) describing original and unpublished work within the scope of the workshop.
- Short papers (up to 10 pages, excluding the bibliography and well-marked appendices) describing original and unpublished work in progress.

The reviewers are not required to read the appendices, so the papers should be intelligible without them. All submissions must be prepared using the LNCS style. Each paper will undergo a thorough review process. Submissions should be made using the GraMSec 2019 EasyChair website: https://easychair.org/conferences/?conf=gramsec2019.

PUBLICATION
As in previous editions, post-proceedings will been made available in the Lecture Notes in Computer Science (LNCS) series, published by Springer. This will published after the workshop, thus permitting the authors to incorporate feedback from workshop attendees and reviewers. Authors whose papers are not selected for presentation at the workshop may also be invited to submit a revised version of their manuscript for publication in the post-proceedings.
