CERIAS Weekly Security Seminar - Purdue University

Reputation systems are crucial to online platforms' health. They are prevalent across online marketplaces and social media platforms either visibly (e.g., as star ratings and badges) or invisibly as signals that feed into recommendation engines. In theory, good behavior (e.g., honest, accurate, high-quality) begets high reputation, while poor behavior is deterred and pushed off the platform.  In this talk, I will discuss how these systems seem to fulfill this mission only coarsely. On one platform, we were able to predict 2 times more suspensions than the reputation system in place using other public signals. On another study, we found that users with high reputation signals were suspended at significantly lower rates (up to 3 times less) for the same number of offenses and behavior as regular users, which suggests they may be impairing content moderation efforts. I will provide some hypotheses to explain these results and offer preliminary findings from current work. About the speaker: Alejandro is a 5th year PhD student at Carnegie Mellon University in Societal Computing, advised by Prof. Nicolas Christin. He is interested in measuring social influence in online communities adjacent to underground economies.

In the realm of risk, cybersecurity is a fairly new idea. Most people currently entering the cybersecurity profession do not remember a time when cybersecurity was not a major concern. Yet at the time of this writing, reliance on computers to run business operations is less than a century old. Prior to this time, operational risk was more concerned with natural disasters than man-made ones. Fraud and staff mistakes are also part of operational risk, so as dependency on computers steadily increased from the 1960s through the 1980s, a then-new joke surfaced: To err is human, but if you really want to screw things up, use a computer.Foundational technology risk management concepts have been in place since the 1970s, but the tuning and the application of these concepts to cybersecurity were slow to evolve. Yet there is no doubt that cybersecurity risk management tools and techniques have continuously improved.. Although the consequences of cybersecurity incidents have become dramatically more profound over the decades, available controls have also become more comprehensive, more ubiquitous, and more effective. This seminar is intended to make the fundamentals of cybersecurity risk management visible to those who are contributing to it, and comprehensible to those looking in from the outside. Like any effort to increasing visibility, increasing transparency in cybersecurity requires clearing out some clouds first. That is, in the tradition of Spaf's recent book on the topic*,  busting some cybersecurity management myths that currently cloud management thinking about cybersecurity and replacing them with risk management methodologies that work.*Spafford, G., Metcalf, L. and Dykstra, J.

The field of cybersecurity is constantly evolving, and Device Fingerprinting (DFP) has emerged as a crucial technique for identifying network devices based on their unique traffic data.This is necessary to protect against sophisticated cyber-attacks. However,automating device classification is complex, as it involves a vast and diverse feature space derived from various network layers, such as application,transport, and physical. With the advances in machine learning and deep learning, DFP has become more accurate and adaptable, integrating multi-layered data and emphasizing the need to balance robust security measures. The study of DFP, especially in the context of emerging protocols like HTTP/2 and HTTP/3,remains a critical area of research in cybersecurity.

Advanced Persistent Threat (APT) attacks are increasingly targeting modern factory floors. Recovery from a cyberattack is a complex task that involves identifying the root causes of the attack in order to thoroughly cleanse the compromised systems and remedy all vulnerabilities. As a result, the provenance analysis, which can correlate individual attack footprints and thus "connect the dots", is very much desired. Provenance analysis has been well studied in traditional IT systems, yet the OS-level attack model, prior work employs, cannot effectively capture application semantics in physical control systems. Recent efforts have been made to develop custom provenance models that uniquely represent physical attacks in cyber-physical systems. Nevertheless, existing techniques still fall short due to their unreliable semantic recovery, inability to reconstruct process contexts, and lack of cross-domain causality tracking. In this talk, we present ICSTracker, which aims to enable provenance analysis in the new setting of industrial IoT. To recover the physical semantics of controller routines, we utilize data mining to identify function call sequences that align with specific physical actions. To establish the process contexts, we resort to the data access patterns in controller code to discover and keep track of critical state variables that are shared among multiple iterations of control logic. To uncover the methods attackers employ in exploiting digital vulnerabilities to cause physical damage, we perform a cross-domain causality analysis, associating controller operations with OS-level events through their mutual access to shared digital assets. We have implemented and tested ICSTracker in a FischerTechnic testbed. Our preliminary results are promising, demonstrating that ICSTracker can precisely capture cross-domain cyber-physical attacks in a semantics and context-aware fashion.

This is a hybrid event. Students are encouraged to attend in person: STEW G52(Suite 050B) Commercial or defense systems are often developed first to meet a mission or customer need. Security of many of these systems is often developed at a component level by each components product team. The product teams often maintain robust security for their component within the system, but security gaps begin to form when the complete system is assembled. Adversaries will seek to exploit these gaps in the overall system design as they look for the path of least resistance to achieve their goals. These adversaries do not limit themselves to one exploitation domain and will often pivot across domains in their execution of an attack. To guard against these multi-domain threats, we as security practitioners and researchers need to work together to adjust our world view on the larger system of system security challenge that we face. This presentation begins the process of enumerating some of these gaps, how gaps came into existence, and provides potential research avenues to address them. About the speaker: Dr. Robert Denz serves as the Director of the Secure and Resilient Systems group at Riverside Research.

Dr. Denz received his PhD in secure hypervisor and kernel design from the Thayer School of Engineering at Dartmouth College in 2016.

The challenge of building a security program is that there are too many things you could be doing, and that creates a challenge for security leaders to decide on which things they should do next.All too often companies pivot from fighting one fire to another fire. They end up cobbling together a security program with duct tape, bailing wire, and a handful of solutions implemented as a reaction to our own incidents and major headlines about other companies' breaches.  How should a CISO evaluate building their security program?In this talk, I will be exploring a mental model that CISOs can use - that I used in my 20 years as a CISO - to evaluate the state of their security program, and to identify where there are gaps in coverage.  At a high level, the framework is four dimensional, covering width (asset coverage), height (control comprehensiveness), depth (risk context), and time (maturity continuity).  I will use case studies to highlight ways the security programs often fail on one of these axes, as a means for participants to connect the programs they work on to the shortcomings others have already experienced.Most ways to evaluate a security program become frameworks with an overly strong focus on detail, but which lose the holistic view of the health of a security program, and even the "known unknowns" (we're pretty sure there is a risk, but don't have specifics) become forgotten as the focus narrows to the "known knowns" (we've documented the risk).  The "unknown unknowns," of course, almost never get visibility.Combining a mental model for assessing the overall maturity of the program, with a high level risk comparison system (the "Pyramid of Pain") allows a CISO to identify areas for improvement to mitigate risk in the future.Case studies from my time at Akamai will be shared (demonstrating not only how to quickly assess risk, but how to understand risk areas that may take years to mitigate), including the risk areas whose mitigation helped propel Akamai into the security leviathan it is today.

During the last several years, there has been growing concern that the development of quantum computers could undermine the public-key cryptography that is a fundamental pillar of security on the Internet. Recently, the U.S. Government's National Institute of Standards and Technology has released draft standards for post-quantum encryption algorithms that can replace the existing, and potentially vulnerable public-key encryption. But while the future of encryption will depend on new algorithms,there are many other factors that will influence security in the decades to come. In 2022, the National Academies of Sciences, Engineering, and Medicine released a report on "The Future of Encryption" that examines factors including technical aspects of cryptography, societal and policy considerations, and product engineering. The report presents a series of findings that apply broadly, and paints three alternative future scenarios for the future of encryption. This presentation, based largely on the Academies report, will provide researchers, engineers, and policy professionals with context in which to view future developments and concepts for prioritizing future actions.

The number of software vulnerabilities found in modern computing systems has been on the rise for some time now. As more and more software is being developed, software testing is increasingly becoming an important part of the software development cycle, with the goal of rooting out any and all vulnerabilities before public release. However, finding software vulnerabilities is not a trivial task, especially in complex software systems with thousands of lines of code and complicated system interactions. Just a single vulnerability making its way into a software product/service can have devastating consequences, if not discovered and patched in good time.Luckily, there is a plethora of available software testing tools and techniques. One such software testing approach is called fuzzing. Fuzzing is an automated program testing technique introduced in the late-1980s, and has become a critical tool in a software tester's toolkit. Fuzzing is based on the simple idea of feeding software lots of mutated inputs and monitoring the program state for any anomalous behavior. Fuzzers have had a long and successful track record of finding software vulnerabilities. This success brought forth new and innovative approaches to improve the overall fuzzing process in all aspects. However, despite its success and widespread use, fuzzing is not a "one size fits all" approach. Software testers still have to tailor their fuzzing methodology to the software under test. Therefore, understanding the inner workings of fuzzers is absolutely vital in order to determine when and how to use them most effectively.

Tracking technologies are proliferating at an increasingly high rate in apps, IoT devices, websites, and in a wide range of files. They are not only impacting privacy in wider and more harmful ways, but they have also extended far beyond the digital world and are also impacting physical safety. Such tools can certainly be very beneficial, when used responsibly and with informed awareness of the cybersecurity and privacy risks. However, when they are used without establishing technical and non-technical boundaries, and without taking risk mitigation actions, the associated surveillance activities can, and have, brought physical harms. I was an expert witness for a case a couple of years ago involving a stalker's use of his victim's smart car to find and almost fatally assault her. I'm currently an expert witness for two separate cases involving the use of Meta Pixels, Conversion APIs, cookies, and other types of tracking tech for surveillance of online activities. Virtually daily there are news articles reporting privacy invasions by digital trackers, drones, security cameras, and more. I will provide several real-life use cases, and provide discussion for the technical and non-technical capabilities that possibly could have been identified through risk assessment activities prior to making such products publicly available and informed the needed associated security and privacy capabilities, that would have supported privacy and cybersecurity protections and physical safety.

With the ever-accelerating computerization process of once strictly mechanical systems, information security threats are only expected to increase. This rapidly unfolding process calls into question whether we could promptly cope with the security threats it entails. Unfortunately, a commonly observed trend is for the computerization process to steadily advance while paying little attention to the security aspect until a security vulnerability is discovered, often by an external actor. Only then, a quest for a suitable security measure begins. In sum, security is considered only in reaction to manifest breaches. This comes at a high price, as the fix is not often found speedily after the breach. In this talk, I will explain how to take a proactive vulnerability identification and defense construction approach to better secure cyber-physical systems. I will discuss two main themes of my research: 1) vulnerability identification and 2) defense construction with a focus on the context of Controller Area Network (CAN) systems.

Recorded: 09/20/2023 CERIAS Security Seminar at Purdue University Enhancing Software Supply Chain Security in Distributed Systems Christopher Nuland, Red Hat In the aftermath of the transformative 2020Solarwinds breach, securing software supply chains has surged to the forefront of modern software development concerns. This incident underscored the imperative for innovative approaches to ensure software artifacts' integrity and authenticity. The Supply Chain Level for Software Artifacts (SLSA)framework emerged as a response, emphasizing secure software development processes for supply chains. As compliance standards, notably enforced by the National Institute of Standards and Technology (NIST), intensify the call for robust security measures, the convergence of open-source technologies presents a compelling solution.In the contemporary landscape of distributed systems, like Kubernetes, the significance of signing critical artifacts, such as container images and builds, cannot be overstated. These signatures substantiate the origin and unaltered state of the artifacts, rendering them resistant to tampering or unauthorized access. Yet, with the escalating complexity of software supply chains, bolstered by the proliferation of distributed technologies, ensuring trustworthy artifact provenance becomes more formidable.This challenge is where SigStore, an innovative technology solution, steps in. SigStore enables cryptographic signing and verification of software artifacts, offering a robust mechanism to establish the authenticity of these components. By leveraging transparency log technologies, SigStore enhances the trustworthiness of the supply chain,creating a formidable barrier against malicious alterations.This talk will discuss the popular technologies in the industry that are utilizing a zero trust software supply chain. Why this type of supply chain is important, and outline the different technologies used in conjunction with SigStore to create zero-trust supply chains within the software development and deployment lifecycle.Christopher Nuland has been involved with container technology since 2010, when he worked with Oak Ridge Labs and Purdue's CdmHub on containerizing their simulations with OpenVZ.
