Measuring Human Performance within Computer Security Incident Response Teams
Human performance has become a pertinent issue within cyber security. However, this research has been stymied by the limited availability of expert cyber security professionals. This is partly attributable to the ongoing workload faced by cyber security professionals, which is compound ed by the limited number of qualified personnel and turnover of personnel across organizations. Additionally, it is difficult to conduct research, and particularly, openly published research, due to the sensitivity inherent to cyber ope rations at most organizations. As an alternative, the current research has focused on data collection during cyber security training exercises. These events draw individuals with a range of knowledge and experience extending from seasoned professionals to recent college graduates to college students. The current paper describes research involving data collection at two separate cyber security exercises. This data collection involved multiple measures which included behavioral performance based on human - machine transactions and questionnaire - based assessments of cyber security experience.

Nested Narratives Final Report
In cybersecurity forensics and incident response, the story of what has happened is the most important artifact yet the one least supported by tools and techniques. Existing tools focus on gathering and manipulating low-level data to allow an analyst to investigate exactly what happened on a host system or a network. Higher-level analysis is usually left to whatever ad hoc tools and techniques an individual may have developed. We discuss visual representations of narrative in the context of cybersecurity incidents with an eye toward multi-scale illustration of actions and actors. We envision that this representation could smoothly encompass individual packets on a wire at the lowest level and nation-state-level actors at the highest. We present progress to date, discuss the impact of technical risk on this project and highlight opportunities for future work.
Factors contributing to performance for cyber security forensic analysis
Lecture Notes in Computer Science (including subseries Lecture Notes in Artificial Intelligence and Lecture Notes in Bioinformatics)
Previously, the current authors (Hopkins et al. 2015) described research in which subjects provided a tool that facilitated their construction of a narrative account of events performed better in conducting cyber security forensic analysis. The narrative tool offered several distinct features. In the current paper, an analysis is reported that considered which features of the tool contributed to superior performance. This analysis revealed two features that accounted for a statistically significant portion of the variance in performance. The first feature provided a mechanism for subjects to identify suspected perpetrators of the crimes and their motives. The second feature involved the ability to create an annotated visuospatial diagram of clues regarding the crimes and their relationships to one another. Based on these results, guidance may be provided for the development of software tools meant to aid cyber security professionals in conducting forensic analysis.
Facilitation of Forensic Analysis Using a Narrative Template
Procedia Manufacturing
Criminal forensic analysis involves examining a collection of clues to construct a plausible account of the events associated with a crime. In this paper, a study is presented that assessed whether software tools designed to encourage construction of narrative accounts would facilitate cyber forensic analysis. Compared to a baseline condition (i.e., spreadsheet with note-taking capabilities) and a visualization condition, subjects performed best when provided tools that emphasized established components of narratives. Specifically, features that encouraged subjects to identify suspected entities, and their activities and motivations proved beneficial. It is proposed that software tools developed to facilitate cyber forensic analysis and training of cyber security professionals incorporate techniques that facilitate a narrative account of events.
Situation Awareness and Automation in the Electric Grid Control Room
Procedia Manufacturing
Electric distribution utilities, the companies that feed electricity to end users, are overseeing a technological transformation of their networks, installing sensors and other automated equipment, that are fundamentally changing the way the grid operates. These grid modernization efforts will allow utilities to incorporate some of the newer technology available to the home user – such as solar panels and electric cars – which will result in a bi-directional flow of energy and information. How will this new flow of information affect control room operations? How will the increased automation associated with smart grid technologies influence control room operators’ decisions? And how will changes in control room operations and operator decision making impact grid resilience? These questions have not been thoroughly studied, despite the enormous changes that are taking place. In this study, which involved collaborating with utility companies in the state of Vermont, the authors proposed to advance the science of control-room decision making by understanding the impact of distribution grid modernization on operator performance. Distribution control room operators were interviewed to understand daily tasks and decisions and to gain an understanding of how these impending changes will impact control room operations. Situation awareness was found to be a major contributor to successful control room operations. However, the impact of growing levels of automation due to smart grid technology on operators’ situation awareness is not well understood. Future work includes performing a naturalistic field study in which operator situation awareness will be measured in real-time during normal operations and correlated with the technological changes that are underway. The results of this future study will inform tools and strategies that will help system operators adapt to a changing grid, respond to critical incidents and maintain critical performance skills.
Toward an Objective Measure of Automation for the Electric Grid
Procedia Manufacturing
The impact of automation on human performance has been studied by human factors researchers for over 35 years. One unresolved facet of this research is measurement of the level of automation across and within engineered systems. Repeatable methods of observing, measuring and documenting the level of automation are critical to the creation and validation of generalized theories of automation's impact on the reliability and resilience of human-in-the-loop systems. Numerous qualitative scales for measuring automation have been proposed. However these methods require subjective assessments based on the researcher's knowledge and experience, or through expert knowledge elicitation involving highly experienced individuals from each work domain. More recently, quantitative scales have been proposed, but have yet to be widely adopted, likely due to the difficulty associated with obtaining a sufficient number of empirical measurements from each system component. Our research suggests the need for a quantitative method that enables rapid measurement of a system's level of automation, is applicable across domains, and can be used by human factors practitioners in field studies or by system engineers as part of their technical planning processes. In this paper we present our research methodology and early research results from studies of electricity grid distribution control rooms. Using a system analysis approach based on quantitative measures of level of automation, we provide an illustrative analysis of select grid modernization efforts. This measure of the level of automation can be displayed as either a static, historical view of the system's automation dynamics (the dynamic interplay between human and automation required to maintain system performance) or it can be incorporated into real-time visualization systems already present in control rooms.
Measuring expert and novice performance within computer security incident response teams
Lecture Notes in Computer Science (including subseries Lecture Notes in Artificial Intelligence and Lecture Notes in Bioinformatics)
There is a great need for creating cohesive, expert cybersecurity incident response teams and training them effectively. This paper discusses new methodologies for measuring and understanding expert and novice differences within a cybersecurity environment to bolster training, selection, and teaming. This methodology for baselining and characterizing individuals and teams relies on relating eye tracking gaze patterns to psychological assessments, human-machine transaction monitoring, and electroencephalography data that are collected during participation in the game-based training platform Tracer FIRE. We discuss preliminary findings from two pilot studies using novice and professional teams.

Training Adaptive Decision-Making
Adaptive Thinking has been defined here as the capacity to recognize when a course of action that may have previously been effective is no longer effective and there is need to adjust strategy. Research was undertaken with human test subjects to identify the factors that contribute to adaptive thinking. It was discovered that those most effective in settings that call for adaptive thinking tend to possess a superior capacity to quickly and effectively generate possible courses of action, as measured using the Category Generation test. Software developed for this research has been applied to develop capabilities enabling analysts to identify crucial factors that are predictive of outcomes in fore-on-force simulation exercises.

Human dimensions in cyber operations research and development priorities
Within cyber security, the human element represents one of the greatest untapped opportunities for increasing the effectiveness of network defenses. However, there has been little research to understand the human dimension in cyber operations. To better understand the needs and priorities for research and development to address these issues, a workshop was conducted August 28-29, 2012 in Washington DC. A synthesis was developed that captured the key issues and associated research questions. Research and development needs were identified that fell into three parallel paths: (1) human factors analysis and scientific studies to establish foundational knowledge concerning factors underlying the performance of cyber defenders; (2) development of models that capture key processes that mediate interactions between defenders, users, adversaries and the public; and (3) development of a multi-purpose test environment for conducting controlled experiments that enables systems and human performance measurement. These research and development investments would transform cyber operations from an art to a science, enabling systems solutions to be engineered to address a range of situations. Organizations would be able to move beyond the current state where key decisions (e.g. personnel assignment) are made on a largely ad hoc basis to a state in which there exist institutionalized processes for assuring the right people are doing the right jobs in the right way. These developments lay the groundwork for emergence of a professional class of cyber defenders with defined roles and career progressions, with higher levels of personnel commitment and retention. Finally, the operational impact would be evident in improved performance, accompanied by a shift to a more proactive response in which defenders have the capacity to exert greater control over the cyber battlespace.
