46 Evolution of Attacks, Threat Models, and Solutions for Virtualized
Evolution of Attacks, Threat Models, and Solutions for Virtualized Systems DANIELE SGANDURRA and EMIL LUPU, Imperial College London Virtualization technology enables Cloud providers to efficiently use their computing services and resources. Even if the benefits in terms of performance, maintenance, and cost are evident, however, virtualization has also been exploited by attackers to devise new ways to compromise a system. To address these problems, research security solutions have evolved considerably over the years to cope with new attacks and threat models. In this work, we review the protection strategies proposed in the literature and show how some of the solutions have been invalidated by new attacks, or threat models, that were previously not considered. The goal is to show the evolution of the threats, and of the related security and trust assumptions, in virtualized systems that have given rise to complex threat models and the corresponding sophistication of protection strategies to deal with such attacks. We also categorize threat models, security and trust assumptions, and attacks against a virtualized system at the different layers—in particular, hardware, virtualization, OS, and application. 46 Categories and Subject Descriptors: K.6.5 [Management of Computing and Information Systems]: Security and Protection—Unauthorized access General Terms: Security, Algorithms, Measurement Additional Key Words and Phrases: Virtualization, threat models, Cloud computing, integrity attacks ACM Reference Format: Daniele Sgandurra and Emil Lupu. 2016.

Scada & Plc Vulnerabilities in Correctional Facilities
SCADA & PLC VULNERABILITIES IN CORRECTIONAL FACILITIES White Paper Teague Newman Tiffany Rad, ELCnetworks, LLC John Strauchs, Strauchs, LLC 7/30/2011 © 2011 Newman, Rad, Strauchs PLC Vulnerabilities in Correctional Facilities Newman, Rad, Strauchs Abstract On Christmas Eve not long ago, a call was made from a prison warden: all of the cells on death row popped open. Not sure how or if it could happen again, the prison warden requested security experts to investigate. Many prisons and jails use SCADA systems with PLCs to open and close doors. As a result of Stuxnet academic research, we have discovered significant vulnerabilities in PLCs used in correctional facilities by being able to remotely flip the switches to “open” or “locked closed” on cell doors and gates. Using original and publically available exploits along with evaluating vulnerabilities in electronic and physical security designs, we will analyze SCADA systems and PLC vulnerabilities in correctional and government secured facilities while making recommendations for improved security measures. 1 PLC Vulnerabilities in Correctional Facilities Newman, Rad, Strauchs Biographies John J. Strauchs, M.A., C.P.P., conducted the security engineering or consulting for more than 114 justice design (police, courts, and corrections) projects in his career, which included 14 federal prisons, 23 state prisons, and 27 city or county jails. He owned and operated a professional engineering firm, Systech Group, Inc., for 23 years and is President of Strauchs, LLC. He was an equity principal in charge of security engineering for Gage-Babcock & Associates and an operations officer with the U.S. Central Intelligence Agency (CIA). His company and work was an inspiration for the 1993 movie, “Sneakers” for which he was the Technical Advisor. -

Pillia, , Vijay Varadharajanb, Udaya Tupakulab a Department of Computer Science and Engineering, Malaviya National Institute of Technology Jaipur, India b Department of Computing, Faculty of Science and Engineering, Macquarie University, Sydney, Australia ARTICLE INFO ABSTRACT Keywords: Security is of paramount importance in this new era of on-demand Cloud Computing. Researchers have Intrusion detection provided a survey on several intrusion detection techniques for detecting intrusions in the cloud computing Cloud security environment. Most of them provide a discussion over traditional misuse and anomaly detection techniques. Virtual machine introspection Virtual Machine Introspection (VMI) techniques are very helpful in detecting various stealth attacks targeting Hypervisor introspection user-level and kernel-level processes running in virtual machines (VMs) by placing the analyzing component Cloud attacks outside the VM generally at hypervisor. Hypervisor Introspection (HVI) techniques ensure the hypervisor security and prevent a compromised hypervisor to launch further attacks on VMs running over it. Introspection techniques introspect the hypervisor by using hardware-assisted virtualization-enabled technologies. The main focus of our paper is to provide an exhaustive literature survey of various Intrusion Detection techniques proposed for cloud environment with an analysis of their attack detection capability. We propose a threat model and attack taxonomy in cloud environment to elucidate the vulnerabilities in cloud. Our taxonomy of IDS techniques represent the state of the art classification and provides a detailed study of techniques with their distinctive features. -

Cloud computing offers several benefits to Cloud computing users and organizations, in terms of capital expenditure and savings in operational expenditure. Crypto-cloud Despite the existence of such benefits, there are some obstacles that place restrictions on the Issues in cloud usage of cloud computing. Security is a major issue that is always considered. The lack of this Virtualization vital feature results in the negative impact of the computing archetype thus resulting in personal, ethical, and financial harm. This paper will focus and explore the security challenges that are faced by cloud entities. These entities include Cloud Service Provider, the Data Owner and Cloud User.

Studying the causes and effects of various cyber attacks it will provide the necessary upgrades. 1. Introduction Cloud computing creates a network-based environment vision to the users, which paves way for the sharing of calculations and resources regardless of location. The National Institute of Standards and Technology's (NIST) defines cloud computing [1] as, “A template for providing the suitable and when needed access to the internet, to a collective pool of programmable grids, storage, servers, software, and amenities that can be rapidly emancipated, with little communication and supervision from the provider”. -
Paper: Hacks and Attacks: Examples of Electronic Device Compromise
Hacks and Attacks: Examples of Electronic Device Compromise Embedded Systems Conference Silicon Valley 2010 (ESC-343) Joe Grand* Grand Idea Studio, Inc. ABSTRACT Bolstered by the flourishing hobbyist electronics and do-it-yourself movements, easy access to equipment, and nearly realtime information sharing courtesy of the Internet, hardware devices have become a target for both harmless, curious hackers and malicious attackers. Many devices are inherently trusted and taken for granted, though they are actually susceptible to compromise leading to potential financial, social, or legal implications. As engineers, we have a responsibility to learn from problems of the past and anticipate new ones in order to better equip ourselves for designs of the future. This paper will present a typical hardware hacking process and explore a few real- world attacks against electronic devices. WHY HARDWARE? Society thrives on an ever-increasing use of technology. Electronics are embedded into nearly everything we touch. Hardware products are relied on for security-related applications and are inherently trusted, though many are completely susceptible to compromise with simple classes of attacks that have been known for decades. Contrary to conventional thinking, engineering doesn’t only have to be about design and hacking doesn’t have to be illegal. You can combine the best of both worlds - the skills and precision of an engineer with the freewheeling, anti- authoritative mindset of a hacker - to discover, learn about, experiment with, modify, build, break, or improve a product. Whether the goals of a hardware hack or attack are for “good” or for “evil” depends purely on the person or people undertaking the task.
