Exploiting Input Sanitization For Regex Denial Of Service, Efe Barlas, Xin Du, James C. Davis

Department of Electrical and Computer Engineering Faculty Publications

Web services use server-side input sanitization to guard against harmful input. Some web services publish their sanitization logic to make their client interface more usable, e.g., allowing clients to debug invalid requests locally. However, this usability practice poses a security risk. Specifically, services may share the regexes they use to sanitize input strings — and regex-based denial of service (ReDoS) is an emerging threat. Although prominent service outages caused by ReDoS have spurred interest in this topic, we know little about the degree to which live web services are vulnerable to ReDoS.

In this paper, we conduct the first black-box …

Discrepancies Among Pre-Trained Deep Neural Networks: A New Threat To Model Zoo Reliability, Diego Montes, Pongpatapee Peerapatanapokin, Jeff Schultz, Chengjun Guo, Wenxin Jiang, James C. Davis

Department of Electrical and Computer Engineering Faculty Publications

Training deep neural networks (DNNs) takes significant time and resources. A practice for expedited deployment is to use pre-trained deep neural networks (PTNNs), often from model zoos.collections of PTNNs; yet, the reliability of model zoos remains unexamined. In the absence of an industry standard for the implementation and performance of PTNNs, engineers cannot confidently incorporate them into production systems. As a first step, discovering potential discrepancies between PTNNs across model zoos would reveal a threat to model zoo reliability. Prior works indicated existing variances in deep learning systems in terms of accuracy. However, broader measures of reliability for PTNNs from …

Exploring Youths’ Decision To Participate In Stem Afterschool Programs, Brooke M. Stafford, Virginia L. J. Bolshakova

Indiana STEM Education Conference

STEM afterschool programs offer a range of academic, social, and emotional outcomes to support positive youth development. In particular, STEM afterschool programs have been shown to increase student self-efficacy and interest in pursuing STEM careers (Chan et al., 2020; Dabney et al., 2012). Youth must first choose to attend the STEM afterschool programs to gain the many benefits offered. However, participation in such programs decreases as youth get older and encounter additional competing interests (i.e., home responsibilities, jobs, etc.). To get youth to attend, STEM afterschool programs must meet the needs of youth by leveraging resources, activities, and relationships.

Multidisciplinary Staffing In A Graduate Writing Center: Making Writing Labor Visible, Valued, And Shared, Nancy Welch, Diana Hackenburg, Leigh Ann Holterman, Judith Keller, Seth Orman, Vanesa Liliana Perillo, Rebecca Stern, Ashley Waldron

The Writing Center Journal

Writing studies and writing center scholars have recently focused much-needed attention on how graduate student writers are taught, mentored, and supported. This scholarship also points to a persistent and stubborn conundrum: Graduate students must write their way into disciplinary belonging, yet most advisors lack a language for, or even awareness of, the specialized practices and tacit expectations shaping written discourse in their fields. While graduate student–serving writing centers help fill this writing-support gap, a reliance on English and humanities graduate students for staff reproduces a status quo in which the genre awareness and rhetorical vocabulary needed to mentor advanced academic …

While ranging errors associated with LiDAR systems or the imaging quality of RGB cameras are sensor-dependent and …

Physics-Informed Machine Learning To Predict Extreme Weather Events, Rthvik Raviprakash, Jonathan Buchanan, Mahdi Bu Ali

Discovery Undergraduate Interdisciplinary Research Internship

Extreme weather events refer to unexpected, severe, or unseasonal weather events, which are dynamically related to specific large-scale atmospheric patterns. These extreme weather events have a significant impact on human society and also natural ecosystems. For example, natural disasters due to extreme weather events caused more than $90 billion global direct losses in 2015. These extreme weather events are challenging to predict due to the chaotic nature of the atmosphere and are highly correlated with the occurrence of atmospheric blocking. A key aspect for preparedness and response to extreme climate events is accurate medium-range forecasting of atmospheric blocking events.
