Securing Networks by Detecting Logical Flaws in Protocol Implementations

Dr. Endadul Hoque
Postdoctoral Research Associate, Northeastern University

12:00pm Wednesday, 22 February 2017, ITE 325b, UMBC

Implementations of network protocols are integral components of various networked computing systems, spanning from Internet-of-Things (IoT) to enormous data centers. Research efforts to defend these implementations by introducing new designs for security and advocating best practices in secure programming are not always feasible, nor effective. Even rigorous analysis of the design of a protocol is not sufficient, as indicated by the frequent reports of bugs discovered in protocol implementations after deployment. Hence, it is crucial to develop automated techniques and tools to help programmers detect logical flaws in actual implementations of protocols.

In this talk, I will first present an automated compliance checker to analyze operational behavior of a protocol implementation for detecting semantic bugs, which cause the implementation fail to comply with its specifications. Next, I will present an automated testing tool to analyze robustness of a protocol implementation against malicious attacks mounted to degrade its runtime performance (e.g., throughput). Finally, I will conclude with several directions for future research to aid the development of secure networked systems.

Endadul Hoque is a Postdoctoral Research Associate in the College of Computer and Information Science at Northeastern University. He received his PhD in Computer Science from Purdue University in 2015. His research revolves around practical cybersecurity problems in the networking domain.

A Semantically Rich Approach to Automating Big Data and Cloud

Dr. Karuna Joshi
University of Maryland, Baltimore County

12:00pm Monday, 20 February 2017, ITE 325b, UMBC

With the explosion of Big Data and the growth of data science, there is an urgent need to automate the data lifecycle of generation, ingestion, analytics, knowledge extraction, and archival and deletion. With a promise of rapid provisioning, scalability and high computing capability, cloud based services are being adopted as the default computing environment for Big Data analytics.

To effectively manage their data on cloud, organizations need to continuously monitor the rules/constraints and performance metrics listed in a variety of legal contracts. However, these documents, like Service Level Agreements (SLA), privacy policy, regulatory documents, etc., are currently managed as plain text files meant principally for human consumption. Additionally, providers often define their own performance metrics for their services. These factors hinder the automation of steps of the data lifecycle, leading to inefficiencies in using the dynamic and elastic elements of the Data+Cloud ecosystem and require manual effort to monitor the service performance. Moreover, Cloud-based service providers are collecting large amounts of data about their consumers including Personally Identifiable Information (PII) like contact addresses, credit card details, bank account details, etc. They are offering customized service level agreements which indicate how such data will be handled. To see whether these agreements meet individual or corporate requirements, or comply with statutory constraints, currently involves significant human effort.

In this talk, we present the semantically rich approach that we have developed to automatically extract knowledge from large textual datasets, specially legal documents, using text analytics and Semantic Web technologies. We describe the OWL ontologies that we have developed, and the techniques to extract key terms and rules from textual legal documents. We will also illustrate application of our work in domains such as education, healthcare and cybersecurity.

Towards End-to-End Security and Privacy: Accountability
and Data Privacy in the Life Cycle of Big Data

Taeho Jung
Department of Computer Science
Illinois Institute of Technology

11:00am Tuesday, 14 February 2017, ITE 325b, UMBC

The advent of big data has given birth to numerous innovative life-enhancing applications, but the big data is often called as a double-edged sword due to the increased privacy and security threats. Such threats, if unaddressed, will become deadly barriers to the achievement of big opportunities and success anticipated in the big data industry because they may arise at any part of the life cycle of the big data.

In this talk, I will describe my research which addressed various privacy and security issues in the big data life cycle: acquisition, storage, provisioning, and consumption. More specifically, I will briefly present how various types of data can be protected in their acquisition and consumption phases of the life cycle, and subsequently, I will introduce the theoretic foundations of the presented research. Finally, I will present how to make large-scale data trading accountable against dishonest users for the provisioning phase of big data, and this talk will be concluded with my future research agenda briefing.

Taeho Jung is a Ph.D. candidate in Computer Science at Illinois Institute of Technology. His research area, in general, includes privacy and security issues in data mining and provisioning in the big data life cycle. His paper has won a best paper award (IEEE IPCCC 2014), and two of his papers were selected as best paper candidate (ACM MobiHoc 2014) and best paper award runner up (BigCom 2015) respectively. He has served many international conferences as a TPC member, including IEEE DCOSS 2016, IEEE MSN 2016, IEEE IPCCC 2016, and BigCom 2016. He received his B.E. in Computer Software in Tsinghua University in 2011, and he will receive his Ph.D. in May 2017.

Philosophy Department Colloquium

Bayesianism and the Evidence Problem

Lisa Cassell
University of Massachusetts/Amherst

4-6:00pm Wednesday, 15 February 2017, 456 Performing Arts & Humanities

Bayesianism is a theory that gives us norms for how the degrees of belief we have in certain propositions — our “credences” — ought to hang together. For instance, it tells me that if my credence that I will play baseball tomorrow is .3 and my credence that I will play basketball tomorrow is .4, then, if I believe that I will only play one or the other, my credence that I will either play baseball tomorrow or basketball tomorrow is .7. One of Bayesianism’s most attractive features is its updating norm, which gives us a simple and powerful way of revising our beliefs in the light of new evidence. However, Bayesians have an “Evidence Problem”: while their updating norm tells us what to do once we get evidence, it doesn’t tell us what it means to actually have evidence. In this talk, I consider two arguments — one in support of Bayesian’s updating norm and one against it — and show that both of these arguments fail. I go on to consider what these failures teach us about the Evidence Problem. I conclude by considering some different ways of resolving this problem.

 Biomedical Engineering Projects at CAST

Dr. Yordan Kostov

UMBC Center for Advanced Sensing Technology

1-2pm, Friday, 9 December 2016, ITE 229

The Center for Advanced Sensor Technology is currently leading two projects: “Biologics manufacturing on demand,” funded by DARPA, and “A wearable asthma trigger monitoring system with integrated physiological monitor,” funded by NIH.  The first project is focused on shrinking the footprint of a pharmaceutical factory down to suitcase, capable of producing biologics within twelve hours from the start. There is an ample need for drastically rethinking every detail of the process, with the need to miniaturize all the fluidic components (tanks, mixers, purification columns) and to create networked versions of the shakers, pumps, valves and sensors. The presentation highlights the need for novel sensing devices for process control and drug release. The second project is focused on development of three separate sensors for measuring CO2 in blood, concentration of dust particulate in air, and respiration rate.  These sensors must be networked together to collect real time data and transfer them to a central depository via a cell phone app. The presentation highlights the different challenges in creating the sensors.

Dr. Yordan Kostov holds the B.Sc. and M.Sc. in Electrical Engineering, from Odessa Politechnic Institute, Ukraine. He received a Ph.D. Degree in Electrical/Chemical Engineering from Bulgarian Academy of Sciences for his work in the area of optical chemical sensors and biosensors. His post-doctoral training includes fellowships at University of Hannover, Germany and University of Maryland Biotechnology Institute. He was an assistant professor in the Department of Biotechincs, Sofia Technical University, Bulgaria. Since 2000, he is a research professor in the Department of Chemical and Biochemical Engineering, University of Maryland, Baltimore County (UMBC), with an appointment as assistant director of the UMBC Center for Advanced Sensor Technology.

UMBC CSEE Seminar Series

Genetic ancestry predicts striatal dopamine D2 receptors

Dr. Corinde Wiers
National Institute on Alcohol Abuse and Alcoholism, Bethesda, MD

1-2pm Friday, 2 December 2016, ITE 229, UMBC

Genetic ancestry was recently found to be associated with cortical geometry, cortical surface, and total brain volume in humans. Despite ethnic differences in allele frequency in dopaminergic genes associated with dopamine D2/D3 receptor availability (D2R), no study to date has investigated the relationship between genetic ancestry and striatal D2R. Here, we show that genetic informative markers significantly predict dorsal striatal D2R in 117 healthy ethnically diverse residents of the New York metropolitan area using Positron Emission Tomography (PET) with [11C]raclopride, while correcting for age, sex, BMI, education years, and estimated socioeconomic status based on individuals’ ZIP codes. Striatal D2R may thus be modulated by genetic ancestry, although differences in environmental factors between ethnic groups could mediate these effects. Findings may have implications for pharmacological treatment targeting D2R, such as antipsychotic D2R antagonists.

Corinde Wiers, PhD, is a Research Fellow at the National Institute on Alcohol Abuse and Alcoholism, in the Laboratory of Neuroimaging of Nora D. Volkow, M.D. After her studies in Psychology and Psychobiology at the University of Amsterdam (Netherlands) and Sussex University (UK) in 2010, she completed her PhD in Psychology at the Berlin School of Mind and Brain and Free University Berlin (Germany) in 2014, where she investigated neural underpinnings of automatic approach behavior to alcohol cues, and neural effects of behavioral trainings in patients with alcohol use disorder. The main goal of Dr. Wiers’ research is to understand cognitive, neurobiological and (epi)genetic processes involved in drug addiction, using functional MRI, PET, psychophysics and molecular techniques. She currently works on how peripheral epigenetic markers relate to brain functioning in drug addiction and other psychiatric disorders. Further research interests include the neurobiology of sleep, effects of sleep deprivation, comorbidities of sleep and substance use disorders, and how neuroimaging techniques can be of use for treatment in psychiatry.
