1. Effects of High Impact Educational Practices on engineering and computer science student participation, persistence, and success at land grant universities: YEAR 2.

   Asghar, M. ( August 2022 , 2022 ASEE Annual Conference & Exposition)

   Effects of High Impact Educational Practices on Engineering and Computer Science Student Participation, Persistence, and Success at Land Grant Universities: Award# RIEF-1927218 – Year 2 Abstract Funded by the National Science Foundation (NSF), this project aims to investigate and identify associations (if any) that exist between student participation in High Impact Educational Practices (HIP) and their educational outcomes in undergraduate engineering and computer science (E/CS) programs. To understand the effects of HIP participation among E/CS students from groups historically underrepresented and underserved in E/CS, this study takes place within the rural, public university context at two western land grant institutions (one of which is an Hispanic-serving institution). Conceptualizing diversity broadly, this study considers gender, race and ethnicity, and first-generation, transfer, and nontraditional student status to be facets of identity that contribute to the diversity of academic programs and the technical workforce. This sequential, explanatory, mixed-methods study is guided by the following research questions: 1. To what extent do E/CS students participate in HIP? 2. What relationships (if any) exist between E/CS student participation in HIP and their educational outcomes (i.e., persistence in major, academic performance, and graduation)? 3. How do contextual factors (e.g., institutional, programmatic, personal, social, financial, etc.) affect E/CS student awareness of, interest in, and participation in HIP? During Project Year 1, a survey driven quantitative study was conducted. A survey informed by results of the National Survey of Student Engagement (NSSE) from each institution was developed and deployed. Survey respondents (N = 531) were students enrolled in undergraduate E/CS programs at either institution. Frequency distribution analyses were conducted to assess the respondents’ level of participation in extracurricular HIPs (i.e., global learning and study aboard, internships, learning communities, service and community-based learning, and undergraduate research) that have been shown in the literature to positively impact undergraduate student success. Further statistical analysis was conducted to understand the effects of HIP participation, coursework enjoyability, and confidence at completing a degree on the academic success of underrepresented and nontraditional E/CS students. Exploratory factor analysis was used to derive an "academic success" variable from five items that sought to measure how students persevere to attain academic goals. Results showed that a linear relationship in the target population exists and that the resultant multiple regression model is a good fit for the data. During the Project Year 2, survey results were used to develop focus group interview protocols and guide the purposive selection of focus group participants. Focus group interviews were conducted with a total of 27 undergraduates (12 males, 15 females, 16 engineering students, 11 computer science students) across both institutions via video conferencing (i.e., ZOOM) during the spring and fall 2021 semesters. Currently, verified focus group transcripts are being systematically analyzed and coded by a team of four trained coders to identify themes and answer the research questions. This paper will provide an overview of the preliminary themes so far identified. Future project activities during Project Year 3 will focus on refining themes identified during the focus group transcript analysis. Survey and focus group data will then be combined to develop deeper understandings of why and how E/CS students participate in the HIP at their university, taking into account the institutional and programmatic contexts at each institution. Ultimately, the project will develop and disseminate recommendations for improving diverse E/CS student awareness of, interest in, and participation in HIP, at similar land grant institutions nationally.

2. An Examination of Industry Standards of Success within Penetration Testing Groups

   Ducoste, M. ( January 2021 , IEEE Integrated STEM Education Conference)

   While security technology can be nearly impenetrable, the people behind the computer screens are often easily manipulated, which makes the human factor the biggest threat to cybersecurity. This study examined whether college students disclosed private information about themselves, and what type of information they shared. The study utilized pretexting, in which attackers impersonate individuals in certain roles and often involves extensive research to ensure credibility. The goal of pretexting is to create situations where individuals feel safe releasing information that they otherwise might not. The pretexts used for this study were based on the natural inclination to help, where people tend to want to help those in need, and reciprocity, where people tend to return favors given to them. Participants (N=51) answered survey questions that they thought were for a good cause or that would result in a reward. This survey asked for increasingly sensitive information that could be used maliciously to gain access to identification, passwords, or security questions. Upon completing the survey, participants were debriefed on the true nature of the study and were interviewed about why they were willing to share information via the survey. Some of the most commonly skipped questions included “Student ID number” and “What is your mother’s maiden name?”. General themes identified from the interviews included the importance of similarities between the researcher and the subject, the researcher’s adherence to the character role, the subject’s awareness of question sensitivity, and the overall differences between online and offline disclosure. Findings suggest that college students are more likely to disclose private information if the attacker shares a similar trait with the target or if the attacker adheres to the character role they are impersonating. Additionally, this study sheds light on the research limitations, emphasizes the relevance of the human factor in security and privacy, and offers recommendations for future research.

3. Design Hands-on Lab Exercises for Cyber-physical Systems Security Education

   https://doi.org/10.53735/cisse.v9i1.140  

   Chi, Hongmei ; Liu, Jinwei ; Xu, Weifeng ; Peng, Mingming ; DeGoicoechea, Jon ( March 2022 , Journal of The Colloquium for Information Systems Security Education)

   The integration of cyber-physical systems (CPS) has been extremely advantageous to society, it merges the attention of cybersecurity for vehicles as a timely concern as a matter of public and individual. The failure of any vehicle system could have a serious impact on vehicle control and cause undesired consequences. With the growing demand for security in CPS, there are few hands-on labs/modules available for training current students, future engineers, or IT professionals to understand cybersecurity in CPS. This study describes the execution of a free security testbed to replicate a vehicle’s network system and the implementation of this testbed via hands-on lab designed to introduce concepts of vehicle control systems. The hands-on lab simulates insider threat scenarios where students had to use can-utils toolkits and SavvyCAN to send, modify, and capture the network packet and exploit the system vulnerability threats such as replay attacks and fuzzing attacks on the vehicle system. We conducted a case study with 21 university-level students, and all students completed the hands-on lab, pretest, posttest, and a satisfaction survey as part of a non-graded class assignment. The experimental results show that most students were not familiar with cyber-physical systems and vehicle control systems and never had the chance to do any hands-on lab in this field before. Furthermore, students reported that the hands-on lab helped them learn about CAN-bus and rated high scores for enjoyment. We discussed the design of an affordable tool to teach about vehicle control systems and proposed directions for future work.

4. Relationship Between Goal Orientation, Agency, and Motivation in Undergraduate Civil Engineering Students

   O'Hara, R. ; Benson, L. ; Ogle, J. ; Bolding, C.J. ( July 2021 , 2021 ASEE Annual Conference)

   Understanding the underlying psychological constructs that affect undergraduate engineering students’ academic achievement and persistence can inform curricular and programmatic changes in engineering education, with the goal of increasing access and advancement in engineering for a diverse population of students. As part of a larger study examining student experiences in a civil engineering department undergoing curricular and cultural changes, this quantitative study investigated the relationship between goal orientation, agency, and time-oriented motivation, differences in this relationship across academic years, and potential influences from personality types. The larger project seeks to examine the motivation, identity, and sense of belonging for undergraduate civil engineering students; this paper seeks to construct a conceptual model explaining the interactive nature of some of these constructs. A previously tested and established survey that draws from multiple theories of motivation and other affective factors such as agency and identity, and that includes Big 5 personality constructs, was used to collect data from second, third-and fourth-year civil engineering students over a two-year period. Prior studies have focused on the instrument’s latent constructs with sense of belonging. However, no analysis has been conducted to examine how some of the constructs influence each other. Specific latent constructs of goal orientation, agency (students’ beliefs that their career in science or engineering can lead to positive effects on the world), FTP, and personality were selected for secondary data analysis based on theory presented in the literature about relationships between motivation, goal setting, agency, and student perceptions of their future. The sample size of respondents was 843; data cleaning and deletion of missing data (65cases; 7.7%) resulted in a final sample size of 778(92.3% of the original data). This included328 second year, 294 third year and 156 fourth year students. Statistical analyses and modeling included bivariate correlational analysis, MANOVA and MANCOVA. Results indicated significant correlation between goal orientation, agency, and time-oriented motivation. Furthermore, differences in these constructs between academic years and personality type influenced the relationship. FTP differed between sophomores and seniors, with seniors having higher scores, suggesting motivation increases as time in the program increases. Personality significantly influenced these relationships in different ways but had the strongest effect on agency. The findings that certain types of people are not only motivated to go into civil engineering but believe their major will make a difference in the world, have implications for educational practice. Results align with current literature but also shed light onto the effects of personality on time-oriented motivation and agency, expanding theory in engineering education. Further research is needed to determine if the effects of personality hold true for other engineering and science majors.

5. A Game Theoretic Approach to Model Cyber Attack and Defense Strategies

   https://doi.org/10.1109/ICC.2018.8422719  

   Attiah, Afraa ; Chatterjee, Mainak ; Zou, Cliff C. ( July 2018 , IEEE International Conference on Communications)

   Most of the cybersecurity research focus on either presenting a specific vulnerability %or hacking technique, or proposing a specific defense algorithm to defend against a well-defined attack scheme. Although such cybersecurity research is important, few have paid attention to the dynamic interactions between attackers and defenders, where both sides are intelligent and will dynamically change their attack or defense strategies in order to gain the upper hand over their opponents. This 'cyberwar' phenomenon exists among most cybersecurity incidents in the real world, which warrants special research and analysis. In this paper, we propose a dynamic game theoretic framework (i.e., hyper defense) to analyze the interactions between the attacker and the defender as a non-cooperative security game. The key idea is to model attackers/defenders to have multiple levels of attack/defense strategies that are different in terms of effectiveness, strategy costs, and attack gains/damages. Each player adjusts his strategy based on the strategy's cost, potential attack gain/damage, and effectiveness in anticipating of the opponent's strategy. We study the achievable Nash equilibrium for the attacker-defender security game where the players employ an efficient strategy according to the obtained equilibrium. Furthermore, we present case studies of three different types of network attacks and put forth how our hyper defense system can successfully model them. Simulation results show that the proposed game theoretical system achieves a better performance compared to two other fixed-strategy defense systems.
