How do workers within the field of cybersecurity perceive cybersecurity competitions? This study aims to address this question and investigate if competitions left a positive mark on the information security workers who participated in them.
Student research highlight: Secure and resilient distributed machine learning under adversarial environments

Machine learning algorithms, such as support vector machines (SVMs), neutral networks, and decision trees (DTs) have been widely used in data processing for estimation and detection. They can be used to classify samples based on a model built from training data. However, under the assumption that training and testing samples come from the same natural distribution, an attacker who can generate or modify training data will lead to misclassification or misestimation.

This talk will cover various forms of threats that the electronic chip supply chain is up against, as well as defenses against these threats. The talk will elucidate the development of CAD algorithms/tools for this newly emerging field by mostly leveraging principles from other more mature research domains.

Online underground forums serve a key role in facilitating information exchange and commerce between gray market or even cybercriminal actors. In order to streamline
bilateral communication to complete sales, merchants often publicly post their IM contact details, such as their Skype handle. Merchants that publicly post their Skype handle
potentially leak information, since Skype has a known protocol flaw that reveals the IP address(es) of a user when they are online.

As the manufacturing time, quality, and cost associated with additive manufacturing (AM) continue to improve, more and more businesses and consumers are adopting this technology. Some of the key benefits of AM include customizing products, localizing production and reducing logistics. Due to these and numerous other benefits, AM is enabling a globally distributed manufacturing process and supply chain spanning multiple parties, and hence raises concerns about the reliability of the manufactured product. In this work, we first present a brief overview of the potential risks that exist in the cyber-physical environment of additive manufacturing.

Logic locking is an Intellectual Property (IP) protection technique that thwarts IP piracy, hardware Trojans, reverse engineering, and IC overproduction. Researchers have taken multiple attempts in breaking logic locking techniques and recovering its secret key. A Boolean Satisfiability (SAT) based attack has been recently presented that breaks all the existing combinational logic locking techniques.

With current tools and technology, someone who has physical access to a chip can extract the detailed layout of the integrated circuit (IC). By using advanced visual imaging techniques, reverse engineering can reveal details that are meant to be kept secret, such as a secure protocol or novel implementation that offers a competitive advantage.

Industrial control systems (ICSs) are transitioning from legacy-electromechanical-based systems to modern information and communication technology (ICT)-based systems creating a close coupling between cyber and physical components. In this paper, we explore the ICS cybersecurity landscape including: 1) the key principles and unique aspects of ICS operation; 2) a brief history of cyberattacks on ICS; 3) an overview of ICS security assessment; 4) a survey of “uniquely-ICS” testbeds that capture the interactions between the various layers of an ICS; and 5) current trends in ICS attacks and defenses.

Trustworthiness of system-on-chip designs is undermined by malicious logic (Trojans) in third-party intellectual properties (3PIPs). In this paper, duplication, diversity, and isolation principles have been extended to detect build trustworthy systems using untrusted, potentially Trojan-infected 3PIPs.

DDoS-for-hire services, also known as booters, have commoditized DDoS attacks and enabled abusive subscribers of these services to cheaply extort, harass and intimidate businesses and people by taking them offline. However, due to the underground nature of these booters, little is known about their underlying technical and business structure.
Hardware Performance Counter-Based Malware Identification and Detection with Adaptive Compressive Sensing

Hardware Performance Counter-based (HPC) runtime checking is an effective way to identify malicious behaviors of malware and detect malicious modifications to a legitimate program’s control flow. To reduce the overhead in the monitored system which has limited storage and computing resources, we present a “sample-locally-analyze-remotely” technique. The sampled HPC data are sent to a remote server for further analysis. To minimize the I/O bandwidth required for transmission, the fine-grained HPC profiles are compressed into much smaller vectors with Compressive Sensing. The experimental results demonstrate an 80% I/O bandwidth reduction after applying Compressive Sensing, without compromising the detection and identification capabilities.
