This paper surveys the deep learning (DL) approaches for intrusion-detection systems (IDSs) in Internet of Things (IoT) and the associated datasets toward identifying gaps, weaknesses, and a neutral reference architecture. A comparative study of IDSs is provided, with a review of anomaly-based IDSs on DL approaches, which include supervised, unsupervised, and hybrid methods. All techniques in these three categories have essentially been used in IoT environments. To date, only a few have been used in the anomaly-based IDS for IoT. For each of these anomaly-based IDSs, the implementation of the four categories of feature(s) extraction, classification, prediction, and regression were evaluated. We studied important performance metrics and benchmark detection rates, including the requisite efficiency of the various methods. Four machine learning algorithms were evaluated for classification purposes: Logistic Regression (LR), Support Vector Machine (SVM), Decision Tree (DT), and an Artificial Neural Network (ANN). Therefore, we compared each via the Receiver Operating Characteristic (ROC) curve. The study model exhibits promising outcomes for all classes of attacks. The scope of our analysis examines attacks targeting the IoT ecosystem using empirically based, simulation-generated datasets (namely the Bot-IoT and the IoTID20 datasets).
The electric grid serves a vital role in the supply chain of nearly all industrial and commercial organizations. A Microgrid infrastructure can provide this service and beneficial non-emergency services including a variety of generation/energy sources. To demonstrate the applicability of microgrids for energy resiliency, we present a microgrid resiliency case study for United Parcel Service's (UPS) three separate shipping facilities. The goal, to enhance energy security, minimize cost and prevent cascading losses within other related business units. The impacts and consequences of which are quantified in this study using a Mean Failure Cost (MFC) risk assessment measure. MFC accounts for the potential loses to identified stakeholders that may result from a set of identified failures due to a set of identified threats. In this case, our study uses a method we call All Hazards Econometric System (AHES). AHES incorporates the cost of COOP using a strategy that considers the payback period of microgrid installation as compared to other energy delivery strategies.
Cyber-attacks and intrusions in cyber-physical control systems are, currently, difficult to reliably prevent. Knowing a system's vulnerabilities and implementing static mitigations is not enough, since threats are advancing faster than the pace at which static cyber solutions can counteract. Accordingly, the practice of cybersecurity needs to ensure that intrusion and compromise do not result in system or environment damage or loss. In a previous paper [2], we described the Cyberspace Security Econometrics System (CSES), which is a stakeholder-aware and economics-based risk assessment method for cybersecurity. CSES allows an analyst to assess a system in terms of estimated loss resulting from security breakdowns. In this paper, we describe two new related contributions: 1) We map the Cyberspace Security Econometrics System (CSES) method to the evaluation and mitigation steps described by the NIST Guide to Industrial Control Systems (ICS) Security, Special Publication 800-82r2. Hence, presenting an economics-based and stakeholder-aware risk evaluation method for the implementation of the NIST-SP-800-82 guide; and 2) We describe the application of this tailored method through the use of a fictitious example of a critical infrastructure system of an electric and gas utility.
In January 2012, President Obama released the National Strategy for Global Supply Chain Security. International trade has been and continues to be a powerful engine of the United States and global economic growth. The many cybersecurity challenges facing the U.S. include one of which many Americans are unaware – the serious threat posed by vulnerabilities in the cyber supply chain. Of the many components – including hardware, firmware, and software – that compose a technological product, most contain elements stemming from a broad global market, making it difficult to ascertain the complete security of an end product. With the market for technological goods and components continuing to rapidly grow every year, and with everything from missiles to smartphones relying on these information products, the need for mutual trust cyber supply chain security has never been more critical. Enhancing the security of any national interests’ technological supply chain must not destroy the wellfunctioning international market for technology. Instead of the two extremes of “intrusive government mandates” or “do nothing,” the U.S. government is promoting development of private-sector systems for securing and accrediting technology companies that would allow customers – from the federal government to small businesses – to make more informed and riskbased decisions. Organizations of all types (business, academia, government, etc.) are facing risks resulting from their everincreasing reliance on the information infrastructure. Decision and policy makers managing these risks are challenged by a lack of information intelligence concerning the risks and consequences of cyber events (e.g., Sarbanes-Oxley Act, HIPAA, and Gramm-Leach-Bliley ACT). They need to understand the implications of cyber security risks and solutions related to their information infrastructure and business. Risk management investment decisions, within the context of mutual trust among supply chains should involve: (i) a comprehensive approach to cyber security risk management, (ii) credible appropriate data needed to support intelligent decisions, and (iii) assessment of the impacts resulting from the various investment alternatives. Sound, rational IT/business decisions require a comprehensive understanding of the dynamics of information intelligence and the likely effects of cyber security investment choices. As our dependence on the cyber infrastructure and their associated supply chains grow ever larger, more complex, and more distributed, the systems that compose them become more prone to failures and/or exploitation. Trusted Supply Chains values currency and relevance over detail and accuracy. Information explosion describes the pervasive abundance of (public/private) information and the effects of such. Gathering, analyzing, and making use of information constitutes a business/ sociopolitical/ militaryintelligence gathering activity and ultimately poses significant advantages and liabilities to the survivability of "our" society. The combination of increased vulnerability, increased stakes and increased threats make supply chains and their associated processes one of the most important emerging challenges in the evolution of modern cyberspace "mechanization." In their contribution DANE Trusted Email for Supply Chain Management, Joseph Gersch, Dan Massey, and Scott Rose demonstrate the need for trusted email in supply chain management. Spear phishing, forgery, and other attacks can result in data breaches, industrial and government espionage, installation of malware, and financial theft. DANE email extensions are then posited as a solid foundation for global trusted email. The IETF protocol ‘Domain Authentication of Named Entities’ (DANE) described in this paper has been extended from its initial goal of providing TLS web site validation to also offer a foundation for globally scalable and interoperable email security. In the second paper A Structured Analysis of SQL Injection Runtime Mitigation Techniques, Stu Steiner, Daniel Conte de Leon, and Jim Alves-Foss address SQL injection attacks (SQLIA) which still remain one of the most commonly occurring and exploited vulnerabilities. A considerable amount of research
Unauthorized data exfiltrations from both insiders and outsiders are costly and damaging. Network communication resources can be used for transporting data illicitly out of the enterprise or cloud. Combined with built-in malware copying utilities, we define this set of tools as comprising the Data Exfiltration Surface (DXS). For securing valuable data, it is desirable to reduce the DXS and maintain controls on the egress points. Our approach is to host the data in a protected enclave that includes novel Software Data Diode (SDD) installed on a secured, border gateway. The SDD allows copying data into the enclave systems but denies data from being copied out. Simultaneously, it permits remote access with remote desktop and console applications. Our tests demonstrate that we are able to effectively reduce the DXS and we are able to protect data from being exfiltrated through the use of the SDD.

A principal tenet of the scientific method is that experiments must be repeatable. This tenet relies on ceteris paribus (i.e., all other things being equal). As a scientific community, involved in data sciences, we must investigate ways to establish an environment where experiments can be repeated. We can no longer allude to where the data comes from, we must add rigor to the data collection and management process from which our analysis is conducted. This paper describes a computing environment to support repeatable scientific big data experimentation of world-wide scientific literature, and recommends a system that is housed at the Oak Ridge National Laboratory in order to provide value to investigators from government agencies, academic institutions, and industry entities. The described computing environment also adheres to the recently instituted digital data management plan, which involves all stages of the digital data life cycle including capture, analysis, sharing, and preservation, as mandated by multiple United States government agencies. It particularly focuses on the sharing and preservation of digital research data. The details of this computing environment are explained within the context of cloud services by the three layer classification of "Software as a Service", "Platform as a Service", and "Infrastructure as a Service".
Abstract 1 Industrial Control Systems (ICS) are commonly used in industries such as oil and natural gas, transportation, electric, water and wastewater, chemical, pharmaceutical, pulp and paper, food and beverage, as well as discrete manufacturing (e.g., automotive, aerospace, and durable goods.) SCADA systems are generally used to control dispersed assets using centralized data acquisition and supervisory control. Originally, ICS implementations were susceptible primarily to local threats because most of their components were located in physically secure areas (i.e., ICS components were not connected to IT networks or systems). The trend toward integrating ICS systems with IT networks (e.g., efficiency and the Internet of Things) provides significantly less isolation for ICS from the outside world thus creating greater risk due to external threats. Albeit, the availability of ICS/SCADA systems is critical to assuring safety, security and profitability. Such systems form the backbone of our national cyber-physical infrastructure. Herein, we extend the concept of mean failure cost (MFC) to address quantifying availability to harmonize well with ICS security risk assessment. This new measure is based on the classic formulation of Availability combined with Mean Failure Cost (MFC). The metric offers a computational basis to estimate the availability of a system in terms of the loss that each stakeholder stands to sustain as a result of security violations or breakdowns (e.g., deliberate malicious failures).
Smart grid is a complex cyber physical system containing numerous and variety of sources, devices, controllers and loads. Communication/Information infrastructure is the backbone of the smart grid system where different grid components are connected with each other through this structure. Therefore, the drawbacks of the information technology related issues are also becoming a part of the smart grid. Further, smart grid is also vulnerable to the grid related disturbances. For such a dynamic system, disturbance and intrusion detection is a paramount issue. This paper presents a Simulink and OPNET based co-simulated platform to carry out a cyber-intrusion in a cyber-network for modern power systems and smart grids. The cyber attack effect is also characterized for the physical power system. The effectiveness of the co simulated platform is demonstrated by the IEEE 30 bus power system model. The distributed denial of service attack was carried out in the cyber network to see its effect on the physical network. Different physical fault situations in the test system are considered and the results indicate the effectiveness of the proposed co-simulated scheme.

In cybersecurity, there are many influencing economic factors to weigh. This paper considers the defender-practitioner stakeholder points-of-view that involve cost combined with development and deployment considerations. Some examples include the cost of countermeasures, training and maintenance as well as the lost opportunity cost and actual damages associated with a compromise. The return on investment (ROI) from countermeasures comes from saved impact costs (i.e., losses from violating availability, integrity, confidentiality or privacy requirements). A measured approach that informs cybersecurity practice is pursued toward maximizing ROI. To this end for example, ranking threats based on their potential impact focuses security mitigation and control investments on the highest value assets, which represent the greatest potential losses. The traditional approach uses risk exposure (calculated by multiplying risk probability by impact). To address this issue in terms of security economics, we introduce the notion of Cybernomics. Cybernomics considers the cost/benefits to the attacker/defender to estimate risk exposure. As the first step, we discuss the likelihood that a threat will emerge and whether it can be thwarted and if not what will be the cost (losses both tangible and intangible). This impact assessment can provide key information for ranking cybersecurity threats and managing risk.
Cyber physical computing infrastructures typically consist of a number of interconnected sites including both cyber and physical components. In this analysis we studied the various types and frequency of attacks that may be levied on smart grid cyber physical systems. Our information security analysis utilized a dynamic Agent Based Game Theoretic (ABGT) simulation. Such simulations can be verified using a closed form game theory analytic approach to explore larger scale, real world scenarios involving multiple attackers, defenders, and information assets. We concentrated our study on the electric sector failure scenarios from the NESCOR Working Group Study. We extracted four generic failure scenarios and grouped them into three specific threat categories (confidentiality, integrity, and availability) to the system. These specific failure scenarios serve as a demonstration of our simulation. The analysis using our ABGT simulation demonstrates how to model the electric sector functional domain using a set of rationalized game theoretic rules decomposed from the failure scenarios in terms of how those scenarios might impact the cyber physical infrastructure network with respect to CIA.
The Department of Energy Office of Electricity Delivery and Energy Reliability (DOE-OE) CyberSecurity for Energy Delivery Systems (CSEDS) industry led program (DE-FOA-0000359) entitled "Innovation for Increasing CyberSecurity for Energy Delivery Systems (12CSEDS)," awarded a contract to Sypris Electronics LLC to develop a Cryptographic Key Management System for the smart grid (Scalable Key Management Solutions for Critical Infrastructure Protection). Oak Ridge National Laboratory (ORNL) and Sypris Electronics, LLC as a result of that award entered into a CRADA (NFE-11-03562) between ORNL and Sypris Electronics, LLC. ORNL provided its Cyber Security Econometrics System (CSES) as a tool to be modified and used as a metric to address risks and vulnerabilities in the management of cryptographic keys within the Advanced Metering Infrastructure (AMI) domain of the electric sector. ORNL concentrated our analysis on the AMI domain of which the National Electric Sector Cyber security Organization Resource (NESCOR) Working Group 1 (WG1) has documented 29 failure scenarios. The computational infrastructure of this metric involves system stakeholders, security requirements, system components and security threats. To compute this metric, we estimated the stakes that each stakeholder associates with each security requirement, as well as stochastic matrices that represent the probability of a threat to cause a component failure and the probability of a component failure to cause a security requirement violation. We applied this model to estimate the security of the AMI, by leveraging the recently established National Institute of Standards and Technology Interagency Report (NISTIR) 7628 guidelines for smart grid security and the International Electrotechnical Commission (IEC) 63351, Part 9 to identify the life cycle for cryptographic key management, resulting in a vector that assigned to each stakeholder an estimate of their average loss in terms of dollars per day of system operation. To further address probabilities of threats, information security analysis can be performed using game theory implemented in dynamic Agent Based Game Theoretic (ABGT) simulations. Such simulations can be verified with the results from game theory analysis and further used to explore larger scale, real world scenarios involving multiple attackers, defenders, and information assets. The strategy for the game was developed by analyzing five electric sector representative failure scenarios contained in the AMI functional domain from NESCOR WG1. From these five selected scenarios, we characterized them into three specific threat categories affecting confidentiality, integrity and availability (CIA). The analysis using our ABGT simulation demonstrated how to model the AMI functional domain using a set of rationalized game theoretic rules decomposed from the failure scenarios in terms of how those scenarios might impact the AMI network with respect to CIA.
Supervisory Control and Data Acquisition (SCADA) systems are distributed networks dispersed over large geographic areas that aim to monitor and control industrial processes from remote areas and/or a centralized location. They are used in the management of critical infrastructures such as electric power generation, transmission and distribution, water and sewage, manufacturing/industrial manufacturing as well as oil and gas production. The availability of SCADA systems is tantamount to assuring safety, security and profitability. SCADA systems are the backbone of the national cyber-physical critical infrastructure. Herein, we explore the definition and quantification of an econometric measure of availability, as it applies to SCADA systems; our metric is a specialization of the generic measure of mean failure cost.
Information security continues to evolve in response to disruptive changes with a persistent focus on information-centric controls and a healthy debate about balancing endpoint and network protection, with a goal of improved enterprise/business risk management. Economic uncertainty, intensively collaborative styles of work, virtualization, increased outsourcing and ongoing compliance pressures require careful consideration and adaptation. The Cyberspace Security Econometrics System (CSES) provides a measure (i.e., a quantitative indication) of reliability, performance, and/or safety of a system that accounts for the criticality of each requirement as a function of one or more stakeholders interests in that requirement. For a given stakeholder, CSES accounts for the variance that may exist among the stakes one attaches to meeting each requirement. The basis, objectives and capabilities for the CSES including inputs/outputs as well as the structural and mathematical underpinnings contained in this copyright.
