Program Anomaly Detection: Methodology and Practices

Lecturers: Xiaokui Shu, IBM T. J. Watson Research Center, US Danfeng Yao, Department of Computer Science Virginia Tech, US Abstract: This tutorial will present an overview of program anomaly detection, which analyzes normal program behaviors and discovers aberrant executions caused by attacks, miscon figurations, program bugs, and unusual usage patterns. It was  first introduced as an analogy between intrusion detection for programs and the immune mechanism in biology. Advanced models have been developed in the last decade and comprehensive techniques have been adopted such as hidden Markov model and machine learning. We will introduce the audience to the problem of program attacks and the anomaly detection approach against threats. We will give a general de finition for program anomaly detection and derive model abstractions from the de finition. The audience will be walked through the development of program anomaly detection methods from early-age n-gram approaches to complicated pushdown automata and probabilistic models. This procedure will help the audience understand the objectives and challenges in designing program anomaly detection models. We will discuss the attacks that subvert anomaly detection mechanisms. The field map of program anomaly detection will be presented. We will also briefly discuss the applications of program anomaly detection in Internet of Things security. We expect the audience to get an idea of unsolved challenges in the field and develop a sense of future program anomaly detection directions after attending the tutorial.

Security on Wheels: Security and Privacy for Vehicular Communication Systems

Lecturer: Panos Papadimitratos, KTH, Sweden Abstract: This tutorial is concerned with the design of appropriate security and privacy mechanisms and their integration with VC functionality, especially in the light of strict requirements of VC-enabled safety applications. We consider architectural issues, a wide range of protocols, their analysis, and related implementation aspects. The focus will shift as needed: from an in-depth technical treatment to broader applicability and organizational matters; from the current common understanding in industry and standardization bodies to future enhancements and developments, to the latest on implementation and field operational testing. We will first introduce the basics of VC systems and identify related vulnerabilities and threats. Then, we will outline requirements and present the state-of-the-art solution space. In brief, the following will be covered:

  • System assumptions and enabling technologies, adversarial models, security and privacy requirements
  • Basic concepts and architectures for secure and privacy enhancing VC systems
  • Security mechanisms, facilities, and protocols
    • Identity, key, and credential management
    • In-car communication and platform security
    • Secure and privacy preserving VC protocols
      • Vehicle-to-vehicle/vehicle-to-infrastructure
      • Single/multi-hop
      • Transportation safety- and efficiency-related
      • Adaptive and scalable validation mechanisms
    • Data validation and wrong-doer eviction
  • Outlook on the evolving broader landscape

Cryptographic Currencies Crash Course (C5)

Lecturer: Aljosha Judmayer, SBA Research Abstract: “Bitcoin is a rare case where practice seems to be ahead of theory.” Joseph Bonneau et al. [20] This tutorial aims to further close the gap between IT security research and the area of cryptographic currencies and block chains. We will describe and refer to Bitcoin as an example throughout the tutorial, as it is the most prominent representative of a such a system. It also is a good reference to discuss the underlying block chain mechanics which are the foundation of various altcoins (e.g. Namecoin) and other derived systems. In this tutorial, the topic of cryptographic currencies is solely addressed from a technical IT security point-of-view. Therefore we do not cover any legal, sociological, financial and economical aspects. The tutorial is designed for participants with a solid IT security background but will not assume any prior knowledge on cryptographic currencies. Thus, we will quickly advance our discussion into core aspects of this fi eld. [20] J. Bonneau, A. Miller, J. Clark, A. Narayanan, J. A. Kroll, and E. W. Felten.

Introduction to Credit Networks

Lecturer: Aniket Kate, Purdue University, US Abstract: Credit networks model transitive IOweYou (IOU) credit between their users. With their flexible-yet-scalable design and robustness against intrusion, we are observing a rapid increase in their popularity as a backbone of real-world permission-less payment settlement networks (e.g., Ripple and Stellar) as well as several weak-identity systems requiring Sybil-tolerant communication. In payment scenarios, due to their unique capability to unite emerging crypto-currencies and user-defined currencies with the traditional fiat currency and banking systems, several existing and new payment enterprises are entering in this space. Nevertheless, this enthusiasm in the market significantly exceeds our understanding of security, privacy, and reliability of these inherently distributed systems. Currently employed ad hoc strategies to fix apparent flaws have made those systems vulnerable to bigger problems once they become lucrative targets for malicious players. In this tutorial, we first define the concept of IOU credit networks, and describe some of the important credit network applications. We then describe and analyze recent and ongoing projects to improve the credit-network security, privacy and reliability. We end our discussion with interesting  open problems and systems  challenges in the field. This introductory tutorial is accessible to the standard CCS audience with graduate-level security knowledge.

Aniket Kate is an assistant Professor in the the computer science department at Purdue university. He designs, implements, and analyzes privacy and transparency enhancing technologies for networked systems.

On the Security and Scalability of Bitcoin’s Blockchain

Lecturer: Ghassan O. Karame, NEC Laboratories, Europe Abstract: The blockchain emerges as an innovative tool which proves to be useful in a number of application scenarios. A number of large industrial players, such as IBM, Microsoft, Intel, and NEC, are currently investing in exploiting the blockchain in order to enrich their portfolio of products. A number of researchers and practitioners speculate that the blockchain technology can change the way we see a number of online applications today. Although it is still early to tell for sure, it is expected that the blockchain will stimulate considerable changes to a large number of products and will positively impact the digital experience of many individuals around the globe. In this tutorial, we overview, detail, and analyze the security provisions of Bitcoin and its underlying blockchain – eff ectively capturing recently reported attacks and threats in the system. Our contributions go beyond the mere analysis of reported vulnerabilities of Bitcoin; namely, we describe and evaluate a number of countermeasures to deter threats on the system|some of which have already been incorporated in the system. Recall that Bitcoin has been forked multiple times in order to ne-tune the consensus (i.e., the block generation time and the hash function), and the network parameters (e.g., the size of blocks). As such, the results reported in this tutorial are not only restricted to Bitcoin, but equally apply to a number of “altcoins” which are basically clones/forks of the Bitcoin source code. Given the increasing number of alternative blockchain proposals, this tutorial extracts the basic security lessons learnt from the Bitcoin system with the aim to foster better designs and analysis of next-generation secure blockchain currencies and technologies.

Ghassan O. Karame is a Senior Researcher in the Security Group of NEC Research Laboratories in Germany. Until April 2012, he was working as a postdoctoral researcher in the Institute of Information Security of ETH Zurich, Switzerland. He holds a Master of Science degree in Information Networking from Carnegie Mellon University (CMU), and a PhD degree in Computer Science from ETH Zurich. Ghassan is interested in all aspects of security and privacy with a focus on cloud security, SDN/network security, and Bitcoin security.

Privacy and Security in the Genomic Era


Lecturers: Erman Ayday, Bilkent University, Turkey Jean-Pierre Hubaux, EPFL, Switzerland Abstract: With the help of rapidly developing technology, DNA sequencing is becoming less expensive. As a consequence, the research in genomics has gained speed in paving the way to personalized (genomic) medicine, and geneticists need large collections of human genomes to further increase this speed. Furthermore, individuals are using their genomes to learn about their (genetic) predispositions to diseases, their ancestries, and even their (genetic) compatibilities with potential partners. This trend has also caused the launch of health-related websites and online social networks (OSNs), in which individuals share their genomic data (e.g., OpenSNP or 23andMe). On the other hand, genomic data carries much sensitive information about its owner. By analyzing the DNA of an individual, it is now possible to learn about his disease predispositions (e.g., for Alzheimer’s or Parkinson’s), ancestries, and physical attributes. The threat to genomic privacy is magnifi ed by the fact that a person’s genome is correlated to his family members’ genomes, thus leading to interdependent privacy risks. This tutorial will help computer scientists better understand the privacy and security challenges in today’s genomic era. We will first highlight the signi ficance of genomic data and the threats for genomic privacy. Then, we will present the high level descriptions of the proposed solutions to protect the privacy of genomic data and we will discuss future research directions. No prerequisite knowledge on biology or genomics is required for the attendees. We only require the attendees to have a slight background on cryptography and statistics.

Adversarial Data Mining: Big Data Meets Cyber Security

Lecturers: Murat Kantarcioglu, University of Texas at Dallas, US Bowei Xi, Purdue University, US Abstract: Increasing amounts of cyber security incident data ranging from systems logs to vulnerability scan results are being collected. At the same time, manually analyzing these collected data to detect important cyber security events become almost impossible. Hence, data mining techniques are becoming an essential tool for real-world cyber security solutions. One of the most important differences between applying data mining for cyber security and many other data mining applications is the existence of malicious adversaries that continuously adapt their behavior to hide their actions and to make the data mining models ineffective. To address these concerns, over the last couple of years new and novel data mining techniques which is more resilient to such adversarial behavior are being developed in data mining community. We believe that lessons learned as a part of this research direction would be beneficial for cyber security researchers who plan to apply data mining techniques in practice. In this three hour long tutorial, we introduce the foundation, the techniques, and the applications of adversarial data mining to cyber security applications. We first introduce various data mining approaches proposed in the past to defend against active adversaries. We then discuss a game theoretic framework to model the sequential actions of the adversary and the data miner, while both parties try to maximize their utilities. We also introduce a modified support vector machine method and a relevance vector machine method to defend against active adversaries. Intrusion detection and malware detection are two important application areas for adversarial data mining models that will be discussed in details during the tutorial. Finally, we discuss some practical guidelines on how to use adversarial data mining ideas in generic cyber security applications and how to leverage existing big data management tools such as Spark for building data mining algorithms for cyber security.
