In particular, the security of cyber-human systems (CHSs) can be highly influenced by the actions, especially the decisions, of human participants within the system. To provide insight into CHS security and aid decision-makers, we propose the Human-Influenced Task-Oriented Process (HITOP) modeling formalism and the Multiple-Asymmetric-Utility System experimental framework (MAUS) as tools to quantitatively evaluate the influence of human actions, especially human decisions, on CHS security. We present both a modeling definition for the CHS and an ontology for identifying the relationships between CHS elements and human task performance. We introduce the Human Decision Point (HDP) as an explicit construct for modeling human decisions and explain how the HDP may be represented within a CHS model. We provide a formal definition of HITOP, its notions of state, and its execution algorithms. We introduce the MAUS experimental framework and formally define several HDP probability solution methods using it. We solve an example CHS modeling problem, and present a set of example results and decision tools. We develop an executable HITOP modeling formalism and use it to analyze a real-world case study.","Item marked as restricted to the 'UIUC Users [automated]' Group (id=2) by Seth Robbins (srobbins@illinois.edu) on 2013-02-03T19:19:00Z Item is restricted until 2015-02-03T19:18:53Z","Restriction data tranferred 2014-07-01T11:11:53-05:00 Original Data Group with Access UIUC Users [automated] Release Date: 2015-02-03 13:18:53 UTC Reason: Author requested U of Illinois access only (OA after 2yrs) in Vireo ETD system","U of I Only Restriction Lifted for Item 42090 on 2015-02-03T11:00:59Z."]},{"key":"dc:title","label":"Title","values":["Modeling human decision points in complex systems"]}]}],"canonical_facts":{"dc:contributor":["Sanders, William H.","Kirlik, Alex","Mitra, Sayan","Nicol, David M."],"dc:creator":["Eskins, Douglas"],"dc:date":["2013-02-03T19:17:11Z","2015-02-03T11:00:59Z","2012-12"],"dc:description":["Item withdrawn by Mark Zulauf (zulauf@illinois.edu) on 2012-11-29T18:35:58Z Item was in collections: University of Illinois Theses & Dissertations (ID: 1) No. of bitstreams: 1 Eskins_Douglas.pdf: 2816103 bytes, checksum: 759d0544a6e3a3a97699d7f96cc2f028 (MD5)","Made available in DSpace on 2013-02-03T19:17:11Z (GMT).
