Human Factors in Cyber Security

Dr. Josiah Dykstra

Cyber Security Researcher, US Department of Defense

12:00–1:00pm Friday, 13 April 2018, ITE 229, UMBC

Humans play many roles in the effectiveness of cyber security. While users are often blamed for security compromises, human strengths and weaknesses also affect people who perform design, implementation, configuration, monitoring, analysis, and response. The fields of human computer interaction generally, and usable security specifically, have drawn attention and research to some aspects of human factors, but many opportunities remain for future work.

In this talk, I describe several of my research projects related to human factors in cyber security. The first was a study of how individual differences affect cyber security behavior, and active follow-on research to predict users who might become victimized. The second was a study of stress and fatigue in security operations centers, including a new survey instrument for collecting data in tactical environments. The third was a research prototype using augmented reality to assist humans in cyber security analysis, and an analysis of preliminary results.

Finally, I will present and invite discussion about a new idea for improving security by making it “disappear.” Despite decades of tools and techniques for secure development, and valiant work at adoption and usability, it is clear that many users cannot or will not avail themselves of appropriate cyber security options. It may be time to rethink the amount of interaction required for most users, and if hands-off, behind-the-scenes cyber defense should be the norm.

Josiah Dykstra serves as a Senior Executive Service government civilian and Subject Matter Expert for Computer Network Operations research in the Laboratory for Telecommunication Sciences within the Research Directorate of the National Security Agency. His research includes human augmentation, cyber risk assessment, and cyber effects. He is an active collaborator with academic, industry, and government researchers around the country. Dykstra earned the PhD degree in computer science at UMBC in 2013 studying under Alan T. Sherman. Dr. Dykstra is the author of the 2016 O’Reilly book, Essential Cybersecurity Science, Fellow of the American Academy of Forensic Sciences, and winner of the Presidential Early Career Award for Scientists and Engineers.

   Creating Educational Cybersecurity Assessment Tools

Alan T. Sherman
Department of Computer Science and Electrical Engineering
University of Maryland, Baltimore County

12:00–1:00pm Friday, March 9, 2018, ITE 229, UMBC

The Cybersecurity Assessment Tools (CATS) Project provides rigorous evidence-based instruments for assessing and evaluating educational practices. The first CAT will be a Cybersecurity Concept Inventory (CCI) that measures how well students understand basic concepts in cybersecurity (especially adversarial thinking) after a first course in the field. The second CAT will be a Cybersecurity Curriculum Assessment (CCA) that measures how well students understand core concepts after completing a full cybersecurity curriculum. These tools can help identify pedagogies and content that are effective in teaching cybersecurity.

In fall 2014, we carried out a Delphi process that identified core concepts of cybersecurity. In spring 2016, we interviewed twenty-six students to uncover their understandings and misconceptions about these concepts. In fall 2016, we generated our first assessment tool—-a draft CCI, comprising approximately thirty multiple-choice questions. Each question targets a concept; incorrect answers are based on observed misconceptions from the interviews. In fall 2017, we began drafting CCA questions. This year we are validating the draft CCI using cognitive interviews, expert reviews, and psychometric testing. In this talk, I highlight our progress to date in developing the CCI and CCA. Audience members will be given an opportunity to answer sample questions.

Presently there is no rigorous, research-based method for measuring the quality of cybersecurity instruction. Validated assessment tools are needed so that cybersecurity educators have trusted methods for discerning whether efforts to improve student preparation are successful.

Experimentally Measuring the Circuit Complexity
of One-Way Boolean Functions

Brian Weber, CSEE, UMBC

12:00–1:00pm, Friday, 23 February 2018, ITE 229

I present preliminary results from an exhaustive search for one-way functions in certain classes of small Boolean functions.   One-way functions are functions that are easy to compute but hard to invert.  They are vital for cryptography, yet no one has proven their existence for arbitrary input sizes.  For any bounded circuit model of computation, it is possible to search exhaustively over all possible Boolean functions of restricted size and thereby determine for the searched class the maximum disparity between the complexity of any function and its inverse.  Throughout, we assume a circuit model in which each gate has fan-in 2 and fan-out 1.

In his 1985 dissertation at MIT, Steven Boyack carried out the first such search.  For any positive integers n and M, let F_n,M denote the set of Boolean functions with n inputs and Moutputs. Using circuit size as the complexity measure, Boyack searched the space of every combinatorial function in F_3,3 by searching each of 52 equivalency classes of functions in this space.  He found that every function class in this space has an identically sized inverse.  He was able to prove that functions do exist with more complex inverses outside the space he searched, but not by more than a constant factor.

In spring 2017, using circuit depth as the complexity measure, I searched all injective functions up to F_8,8 whose coordinate functions are in F_2,1.  A coordinate function in this context refers to the function that computes an individual output bit.  In addition, I searched up to F_4,4 allowing coordinate functions in F_3,1.  In the space I searched, the most one-way function has fixed depth of 1, and an inverse depth exactly equal to the input size of the function. That is, for each 2 < n < 9, the hardest inverse in the space I searched has a depth of n, where n is the number of input bits. In addition, a search space allowing a larger fan-in for the coordinate functions did not yield functions less invertible than were found in the original search space.

UMBC’s Haibin Zhang shares tips to secure data in the cloud

As more consumers rely on cloud-based data storage for everything from family photos to financial information, both experts and general users have voiced concerns about cloud security. In a new Conversation article recently published by Scientific American, Haibin Zhang, assistant professor of computer science and electrical engineering, explains precautions consumers can take to protect their files in the cloud.

Zhang explains that data stored and secured using commercial cloud storage systems is encrypted, which means that without the key, the information looks like a series of meaningless characters. Encryption keys have the potential to be misused, if they end up in the wrong hands, which can compromise the security of files stored in a cloud.

“Just like regular keys, if someone else has them, they might be stolen or misused without the data owner knowing,” says Zhang. “And some services might have flaws in their security practices that leave users’ data vulnerable.”

Zhang notes that some cloud services allow customers to maintain their encryption key themselves, which give the consumer the control in ensuring that their data remains safe. Other services keep the encryption keys internally and manage the security for their customers. He says that while each option has benefits, it is important to recognize that “some services might have flaws in their security practices that leave users’ data vulnerable.”

To keep data secure in the cloud, Zhang suggests using enhanced security features offered by cloud storage companies and taking additional precautions that are available to individual customers. He recommends that people use a cloud storage service that allows customers to encrypt their data before uploading it for storage, and to rely on services that have been “validated by independent security researchers.”

Read “How secure is your data when it’s stored in the cloud?” in The Conversation for Zhang’s additional recommendations on securing data on the cloud. The piece also appeared in Scientific American, and has so far been read nearly 20,000 times.

Towards Hardware Cybersecurity

Professor Houman Homayoun
George Mason University

11:00am-12:00pm Tuesday, 20 Febuary 2018, ITE 325, UMBC

Electronic system security, trust and reliability has become an increasingly critical area of concern for modern society. Secure hardware systems, platforms, as well as supply chains are critical to industry and government sectors such as national defense, healthcare, transportation, and finance.

Traditionally, authenticity and integrity of data has been protected with various security protocol at the software level with the underlying hardware assumed to be secure, and reliable. This assumption however is no longer true with an increasing number of attacks reported on the hardware. Counterfeiting electronic components, inserting hardware trojans, and cloning integrated circuits are just few out of many malicious byproducts of hardware vulnerabilities, which need to be urgently addressed.

In the first part of this talk I will address the security and vulnerability challenges in the horizontal integrated hardware development process. I will then present the concept of hybrid spin-transfer torque CMOS look up table based design which is our latest effort on developing a cost-effective solution to prevent physical reverse engineering attacks.

In the second part of my talk I will present how information at the hardware level can be used to address some of the major challenges of software security vulnerabilities monitoring and detection methods. I will first discuss these challenges and will then show how the use of data at the hardware architecture level in combination with an effective machine learning based predictor helps protecting systems against various classes of hardware vulnerability attacks.

I will conclude the talk by emphasizing the importance of this emerging area and proposing a research agenda for the future.

UMBC faculty, alumni and corporate partners discuss cybersecurity and industry challenges

Cybersecurity is regularly a headliner in the news, especially when personal information stored online has been compromised, whether through a breach, hack, or threat. On Thursday, December 7, UMBC hosted experts from industry and academia at the National Press Club to discuss the cyber challenges professionals face, and how those groups can work together to prepare future generations of cybersecurity professionals.

Scott Shane, a reporter with The New York Times, led the discussion with five panelists representing industry, small business, and higher education. “I think it’s fair to say the internet was built without adequate attention to security,” stated Shane, who writes about cyber and information attacks regularly. “It’s almost like somebody who starts a bank with branches all over the world, and after it’s up and running and has millions of account holders, suddenly starts to think about safes, locks on the doors and bulletproof glass. I think that’s sort of the stage that we’re at right now.”

UMBC President Freeman Hrabowski and Anupam Joshi, professor and chair of computer science and electrical engineering, and director of the Center for Cybersecurity at UMBC, were joined by alumni and partners who have been working on the challenge of educating the workforce together. Hrabowski explained that there are currently about 350,000 unfilled cybersecurity jobs, and that number is expected to continue to grow. By 2021, it is anticipated that there will be approximately three million job openings in cyber-related fields.

Over the course of his professional career, Nigel Faulkner, chief technology officer at T. Rowe Price, has experienced the emergence of technology and many changes. “As the CTO of a medium-large company, cyber is a defensive investment for us. The best thing that can happen is nothing happens,” Faulkner said, adding that he is always thinking about whether the company is investing enough, doing the right thing, and making the right connections in the industry to keep clients’ information safe.

As president and founder of TCecure, LLC, and cybersecurity academic innovation officer for University System of Maryland (USM), Tina Williams ’02, computer science, shared the importance of building security into technology from the beginning, rather than adding these features on at the “tail end of a development cycle.” Not only does her company handle security, they also monitor threats and risks that can compromise the technology’s health. In her role at USM, Williams represents the system as a whole to integrate academia and academic research, relationships, and resources into what’s taking place nationally, at the Federally Funded Research and Development Centers.

As head of UMBC’s Center for Cybersecurity, Joshi explained that UMBC is combating these national challenges by partnering with industry and government leaders to conduct research that addresses specific real-world needs that benefit both. Collaborative relationships, such as UMBC’s work with Northrop Grumman and T. Rowe Price, is one way that UMBC is working to cultivate the next generation of cybersecurity talent.

As an alumna of UMBC and a current employee at Northrop Grumman, Lauren Mazzoli ’15, computer science and mathematics, M.S. ’17, computer science, a systems engineer in the Future Technical Leaders Program at Northrop Grumman, discussed her experience in the Cyber Scholars Program. The Cyber Scholars Program works to increase the participation of women and underrepresented minorities in the field. Mazzoli explained that her experience at UMBC, in the Cyber Scholars Program, and working alongside mentors on and off-campus led her to be involved with continuing to encourage women to pursue careers in cybersecurity. “For me it’s been a product of the relationship between academia and industry, that have allowed me to find my own career path, and at the same time help others find theirs,” she explained, noting her passion for helping students consider careers in cybersecurity and related fields.

“We know there’s a huge workforce that we need and we can’t fill that pipeline. So yes, we need more women, yes, we need students of all backgrounds, but we need diversity of thought, experience, education, and problem-solving skills,” said Mazzoli, adding that it is important for students to know from a young age that cybersecurity is a field they can pursue.
