Analysis Of Bulk Power System Resilience Using Vulnerability Graph, Md Ariful Haque Jul 2018

Analysis Of Bulk Power System Resilience Using Vulnerability Graph, Md Ariful Haque

Computational Modeling & Simulation Engineering Theses & Dissertations

Critical infrastructure such as a Bulk Power System (BPS) should have some quantifiable measure of resiliency and definite rule-sets to achieve a certain resilience value. Industrial Control System (ICS) and Supervisory Control and Data Acquisition (SCADA) networks are integral parts of BPS. BPS or ICS are themselves not vulnerable because of their proprietary technology, but when the control network and the corporate network need to have communications for performance measurements and reporting, the ICS or BPS become vulnerable to cyber-attacks. Thus, a systematic way of quantifying resiliency and identifying crucial nodes in the network is critical for addressing the cyber …


Comparative Study Of Deep Learning Models For Network Intrusion Detection, Brian Lee, Sandhya Amaresh, Clifford Green, Daniel Engels Apr 2018

Comparative Study Of Deep Learning Models For Network Intrusion Detection, Brian Lee, Sandhya Amaresh, Clifford Green, Daniel Engels

SMU Data Science Review

In this paper, we present a comparative evaluation of deep learning approaches to network intrusion detection. A Network Intrusion Detection System (NIDS) is a critical component of every Internet connected system due to likely attacks from both external and internal sources. A NIDS is used to detect network born attacks such as Denial of Service (DoS) attacks, malware replication, and intruders that are operating within the system. Multiple deep learning approaches have been proposed for intrusion detection systems. We evaluate three models, a vanilla deep neural net (DNN), self-taught learning (STL) approach, and Recurrent Neural Network (RNN) based Long Short …


Exploring Sme Vulnerabilities To Cyber-Criminal Activities Through Employee Behavior And Internet Access, Jerry Allen Twisdale Jan 2018

Exploring Sme Vulnerabilities To Cyber-Criminal Activities Through Employee Behavior And Internet Access, Jerry Allen Twisdale

Walden Dissertations and Doctoral Studies

Cybercriminal activity may be a relatively new concern to small and medium enterprises (SMEs), but it has the potential to create financial and liability issues for SME organizations. The problem is that SMEs are a future growth target for cybercrime activity as larger corporations begin to address security issues to reduce cybercriminal risks and vulnerabilities. The purpose of this study was to explore a small business owner's knowledge about to the principal elements of decision making for SME investment into cybersecurity education for employees with respect to internet access and employee vulnerabilities. The theoretical framework consisted of the psychological studies …


A Security Review Of Local Government Using Nist Csf: A Case Study, Ahmed Ibrahim, Craig Valli, Ian Mcateer, Junaid Chaudhry Jan 2018

A Security Review Of Local Government Using Nist Csf: A Case Study, Ahmed Ibrahim, Craig Valli, Ian Mcateer, Junaid Chaudhry

Research outputs 2014 to 2021

Evaluating cyber security risk is a challenging task regardless of an organisation’s nature of business or size, however, an essential activity. This paper uses the National Institute of Standards and Technology (NIST) cyber security framework (CSF) to assess the cyber security posture of a local government organisation in Western Australia. Our approach enabled the quantification of risks for specific NIST CSF core functions and respective categories and allowed making recommendations to address the gaps discovered to attain the desired level of compliance. This has led the organisation to strategically target areas related to their people, processes, and technologies, thus mitigating …


Cyber Security And Criminal Justice Programs In The United States: Exploring The Intersections, Brian K. Payne, Lora Hadzhidimova Jan 2018

Cyber Security And Criminal Justice Programs In The United States: Exploring The Intersections, Brian K. Payne, Lora Hadzhidimova

Sociology & Criminal Justice Faculty Publications

The study of cyber security is an interdisciplinary pursuit that includes STEM disciplines as well as the social sciences. While research on cyber security appears to be central in STEM disciplines, it is not yet clear how central cyber security and cyber crime is to criminal justice scholarship. In order to examine the connections between cyber security and criminal justice, in this study attention is given to the way that criminal justice scholars have embraced cyber crime research and coursework. Results show that while there are a number of cyber crime courses included in criminal justice majors there are not …
