Zareen Syed, Ankur Padia, Tim Finin, Lisa Mathews and Anupam Joshi, UCO: Unified Cybersecurity Ontology
, AAAI Workshop on Artificial Intelligence for Cyber Security (AICS), February 2016.
In this paper we describe the Unified Cybersecurity Ontology (UCO) that is intended to support information integration and cyber situational awareness in cybersecurity systems. The ontology incorporates and integrates heterogeneous data and knowledge schemas from different cybersecurity systems and most commonly used cybersecurity standards for information sharing and exchange. The UCO ontology has also been mapped to a number of existing cybersecurity ontologies as well as concepts in the Linked Open Data cloud. Similar to DBpedia which serves as the core for general knowledge in Linked Open Data cloud, we envision UCO to serve as the core for cybersecurity domain, which would evolve and grow with the passage of time with additional cybersecurity data sets as they become available. We also present a prototype system and concrete use cases supported by the UCO ontology. To the best of our knowledge, this is the first cybersecurity ontology that has been mapped to general world ontologies to support broader and diverse security use cases. We compare the resulting ontology with previous efforts, discuss its strengths and limitations, and describe potential future work directions.

Is your personal data at risk?
App analytics to the rescue
10:30am Monday, 28 September 28 2015, ITE346
According to Virustotal, a prominent virus and malware tool, the Google Play Store has a few thousand apps from major malware families. Given such a revelation, access control systems for mobile data management, have reached a state of critical importance. We propose the development of a system which would help us detect the pathways using which user’s data is being stolen from their mobile devices. We use a multi layered approach which includes app meta data analysis, understanding code patterns and detecting and eventually controlling dynamic data flow when such an app is installed on a mobile device. In this presentation we focus on the first part of our work and discuss the merits and flaws of our unsupervised learning mechanism to detect possible malicious behavior from apps in the Google Play Store.

Wenjia Li, Anupam Joshi and Tim Finin, SVM-CASE: An SVM-based Context Aware Security Framework for Vehicular Ad-hoc Networks, IEEE 82nd Vehicular Technology Conf., Boston, Sept. 2015.
Vehicular Ad-hoc Networks (VANETs) are known to be very susceptible to various malicious attacks. To detect and mitigate these malicious attacks, many security mechanisms have been studied for VANETs. In this paper, we propose a context aware security framework for VANETs that uses the Support Vector Machine (SVM) algorithm to automatically determine the boundary between malicious nodes and normal ones. Compared to the existing security solutions for VANETs, The proposed framework is more resilient to context changes that are common in VANETs, such as those due to malicious nodes altering their attack patterns over time or rapid changes in environmental factors, such as the motion speed and transmission range. We compare our framework to existing approaches and present evaluation results obtained from simulation studies.

Ph.D. Dissertation Proposal
User Identification in Wireless Networks
9:00-11:00pm Friday, 27 February 2015, ITE 325B
Wireless communication using the 802.11 specifications is almost ubiquitous in daily life through an increasing variety of platforms. Traditional identification and authentication mechanisms employed for wireless communication commonly mimic physically connected devices and do not account for the broadcast nature of the medium. Both stationary and mobile devices that users interact with are regularly authenticated using a passphrase, pre-shared key, or an authentication server. Current research requires unfettered access to the user’s platform or information that is not normally volunteered.
We propose a mechanism to verify and validate the identity of 802.11 device users by applying machine learning algorithms. Existing work substantiates the application of machine learning for device identification using Commercial Off-The-Shelf (COTS) hardware and algorithms. This research seeks the refinement of and investigation of features relevant to identifying users. The approach is segmented into three main areas: a data ingest platform, processing, and classification.
Initial research proved that we can properly classify target devices with high precision, recall, and ROC using a sufficiently large real-world data set and a limited set of features. The primary contribution of this work is exploring the development of user identification through data observation. A combination of identifying new features, creating an online system, and limiting user interaction is the objective. We will create a prototype system and test the effectiveness and accuracy of it’s ability to properly identify users.

The North American electric power system has been called the world’s largest interconnected machine and is a key part of our national infrastructure. The power grid is evolving to better exploit modern information technology and become more integrated with our cyber infrastructure. This presents unprecedented opportunities for enhanced management and efficiency but also introduces vulnerabilities for intrusions, cascading disruptions, malicious attacks, inappropriate manipulations and other threats. Similar issues are foreseen for other cyber-physical infrastructure systems including industrial control systems, transportation, water, natural gas and waste disposal.
A one-day Smart Grid Cyber Security Conference will be held at UMBC on February 15, hosted by the UMBC Computer Science and Electrical Engineering Department and Maryland Clean Energy Technology Incubator. The conference will be a comprehensive presentation by the National Institute of Standards and Technology regarding an Inter-agency Report 7628 (NISTIR 7628) named Guidelines for Smart Grid Cyber Security which is a critically important document for guiding government, regulatory organizations, industry and academia on Smart Grid cybersecurity. This regional outreach conference is valuable to any organization that is planning, integrating, executing or developing cyber technology for the Smart Grid.
The conference is free, but participants are asked to register in advance to help us organize for the correct number of participants.

The DoD-sponsored JASON study group was asked to consider the question of whether there is a ‘science’ to cyber-security or if it is fundamentally empirical. They released an 88-page report last month, Science of Cyber-Security with the following abstract:
“JASON was requested by the DoD to examine the theory and practice of cyber-security, and evaluate whether there are underlying fundamental principles that would make it possible to adopt a more scientific approach, identify what is needed in creating a science of cyber-security, and recommend specific ways in which scientific methods can be applied. Our study identified several sub-?elds of computer science that are specifically relevant and also provides some recommendations on further developing the science of cyber-security.”
The report discusses to general technical approaches to putting cyber-security on a scientific foundation. The first is based on the standard collection of frameworks and tools grounded in logic and mathematics such as cryptography, game theory, model checking and software verification. The second is grounding cyber-security on a model based on an analog to immunology in biological systems.
It concludes with some observations, recommendations and responses to nine questions that were included in their charge. One interesting observation is that cyber-security, unlike the physical sciences, involves adversaries, so its foundation will use many different tools and methods. A recommendation is that the government establish cyber-security research centers in universities and other research organizations with a “long time horizon and periodic reviews of accomplishments”.
