Abstract: Phishing cyber threats impact private and public sectors both in the United States and internationally. Embedded phishing awareness training programs, in which simulated phishing emails are sent to employees, are designed to prepare employees in these organizations to combat real-world phishing scen...

Conference: IEEE Cyber Physical Systems Security Workshop Abstract: Matter is an open-source connectivity standard for the purpose of allowing smart home IoT devices from different vendors to interoperate with one another. A controller in a Matter system commissions new devices into the Matter fabric. The device needs to present a credential called Device Attestatio...

Conference: USENIX Symposium on Usable Privacy and Security (SOUPS) 2023 Abstract: With youth increasingly accessing and using the internet, it is important to understand what they know about online privacy and security (OPS), and from where they gain this knowledge in order to best support their learning and online practices. Currently, the field of literature surrounding such yo...

Journal: Computer Communications Abstract: Zero-day attacks exploit unknown vulnerabilities so as to avoid being detected by cybersecurity detection tools. The studies Bilge and Dumitras (2012), Google (0000) and Ponemon Sullivan Privacy Report (2020) show that zero-day attacks are wide spread and are one of the major threats to computer sec...

Conference: International Conference on Information Systems Security (ICISS 2022) Abstract: The past several years have witnessed rapidly increasing use of machine learning (ML) systems in multiple industry sectors. Since risk analysis is one of the most essential parts of the real-world ML system protection practice, there is an urgent need to conduct systematic risk analysis of ML system...

Conference: 8th Workshop on Security Information Workers (WSIW 2022) Abstract: The goal of organizational security awareness programs is to positively influence employee security behaviors. However, organizations may struggle to determine program effectiveness, often relying on training policy compliance metrics (training completion rates) rather than measuring actual impact....

Abstract: The President’s Executive Order (EO) on “Improving the Nation’s Cybersecurity (14028)” issued on May 12, 2021, charges multiple agencies – including NIST – with enhancing cybersecurity through a variety of initiatives related to the security and integrity of the software supply chain. The EO acknowl...

Abstract: Organizational security awareness programs experience a number of challenges, including lack of resources, difficulty measuring the impact of the program, and perceptions among the workforce that training is a boring, “check-the-box” activity. While prior surveys and research have examined programs...

Abstract: The Industrial Internet of Things (IIoT) refers to the application of instrumentation and connected sensors and other devices to machinery and vehicles in the transport, energy, and other critical infrastructure sectors. In the energy sector, distributed energy resources (DERs) such as solar photovo...

Abstract: This publication provides a methodology and set of procedures for conducting assessments of security and privacy controls employed within systems and organizations within an effective risk management framework. The assessment procedures, executed at various phases of the system development life cycl...

Conference: Seventeenth IFIP 11.9 International Conference on Digital Forensics Abstract: Attacks on the Internet of Things are increasing. Unfortunately, transparency and accountability that are paramount to securing Internet of Things devices are either missing or implemented in a questionable manner. Security auditing is a promising solution that has been applied with success in other...

Abstract: An organization often has mission and business-based needs to exchange (share) information with one or more other internal or external organizations via various information exchange channels; however, it is recognized that the information being exchanged also requires the same or similar level of pr...

Abstract: Multivariate cryptography is dominated by schemes supporting various modifiers to patch certain algebraic weaknesses. Typically these modifiers are linear in nature--- either requiring an extra composition with an affine map, or being evaluated by a legitimate user via an affine projection. This des...

Abstract: Businesses face a near-constant threat of destructive malware, ransomware, malicious insider activities, and even honest mistakes that can alter or destroy critical data. These data corruption events could cause a significant loss to a company’s reputation, business operations, and bottom line. The...

Abstract: Currently the National Institute of Standards and Technology (NIST) is engaged in a post- quantum standardization effort, analyzing numerous candidate schemes to provide security against the advancing threat of quantum computers. Among the candidates in the second round of the standardization proces...

Abstract: Few software development life cycle (SDLC) models explicitly address software security in detail, so secure software development practices usually need to be added to each SDLC model to ensure the software being developed is well secured. This white paper recommends a core set of high-level secure s...

Conference: 11th International Workshop on Post-Quantum Cryptography (PQCrypto 2020) Abstract: In 2013, Tao et al. introduced the ABC Simple Matrix Scheme for Encryption, a multivariate public key encryption scheme. The scheme boasts great efficiency in encryption and decryption, though it suffers from very large public keys. It was quickly noted that the original proposal, utilizing square m...

Abstract: Title III of the E-Government Act of 2002, entitled the Federal Information Security Management Act (FISMA) of 2002, requires NIST to prepare an annual public report on activities undertaken in the previous year, and planned for the coming year, to carry out responsibilities under this law. The prim...

Conference: Fourteenth International Conference on Software Engineering Advances (ICSEA 2019) Abstract: Previous work presented a theoretical model based on the implicit Bitcoin specification for how an entity might issue a protocol native cryptocurrency that mimics features of fiat currencies. Protocol native means that it is built into the blockchain platform itself and is not simply a token running...

Abstract: The Security Content Automation Protocol (SCAP) version 2 (v2) automates endpoint posture information collection and the incorporation of that information into network defense capabilities using standardized protocols. SCAP v2 expands the endpoint types supported by SCAP v1 through the explicit incl...

Abstract: Title III of the E-Government Act of 2002, entitled the Federal Information Security Management Act (FISMA) of 2002, requires NIST to prepare an annual public report on activities undertaken in the previous year, and planned for the coming year, to carry out responsibilities under this law. The prim...

Conference: 15th International Conference on Quantum Physics and Logic Abstract: Quantum self-testing addresses the following question: is it possible to verify the existence of a multipartite state even when one's measurement devices are completely untrusted? This problem has seen abundant activity in the last few years, particularly with the advent of parallel self-testing (i....

Abstract: This note was originally written under the name "On the Security of HMFEv" and was submitted to PQCrypto 2018. The author was informed by the referees of his oversight of an eprint work of the same name by Hashimoto, see eprint article /2017/689/, that completely breaks HMFEv, rendering the result o...

Journal: Cryptography and Communications Abstract: The multiplicative complexity of a Boolean function is the minimum number of two-input AND gates that are necessary and sufficient to implement the function over the basis (AND, XOR, NOT). Finding the multiplicative complexity of a given function is computationally intractable, even for functions wi...

Journal: Journal of Computer Security Abstract: The administrators of a mission critical network usually have to worry about non-traditional threats, e.g., how to live with known, but unpatchable vulnerabilities, and how to improve the network’s resilience against potentially unknown vulnerabilities. To this end, network hardening is a well-known...
