Secure State Estimation Of Distribution Network Based On Kalman Filter Decomposition, Xinghua Liu, Siwen Dong, Jiaqiang Tian
Secure State Estimation Of Distribution Network Based On Kalman Filter Decomposition, Xinghua Liu, Siwen Dong, Jiaqiang Tian
Journal of System Simulation
A new state estimation algorithm is proposed to improve the accuracy to obtain the optimal state estimation of distribution network against FDI attack. In the case of phasor measurement units being attacked and the measurement results being altered,the optimal Kalman estimate can be decomposed into a weighted sum of local state estimates. Focusing on the insecurity of the weighted sum method,a convex optimization based on local estimation is proposed to replace the method and combine the local estimation into a secure state estimation. The simulation results show that the proposed estimator is consistent with the Kalman …

Two Image Watermarkingmethodsbased On Compressive Sensing, Yidi Miao, Lü Ju, Xiumei Li
Journal of System Simulation
Abstract: As an emerging sample theory, compressive sensing attracts wide attention because it breaks through the Nyquist sampling theorem. , Two different methods of watermark embedding and extraction are presented by measuring the carrier image and watermark image respectively based on compressive sensing. Moreover, the attack tests, such as the Gaussian noise, pepper and salt noise, filtering, compression, and cropping, are implemented to watermarked images. Experiment results show that although the two different methods for image watermarking have different processing procedure, both can guarantee the robustness and security of embedded digital watermark.

Pedagogical Resources For Industrial Control Systems Security: Design, Implementation, Conveyance, And Evaluation, Guillermo A. Francia Iii, Greg Randall, Jay Snellen
Journal of Cybersecurity Education, Research and Practice
Industrial Control Systems (ICS), which are pervasive in our nation’s critical infrastructures, are becoming increasingly at risk and vulnerable to internal and external threats. It is imperative that the future workforce be educated and trained on the security of such systems. However, it is equally important that careful and deliberate considerations must be exercised in designing and implementing the educational and training activities that pertain to ICS. To that end, we designed and implemented pedagogical materials and tools to facilitate the teaching and learning processes in the area of ICS security. In this paper, we describe those resources, the professional …

An Exploration Of Mobile Device Security Artifacts At Institutions Of Higher Education, Amita Goyal Chin, Diania Mcrae, Beth H. Jones, Mark A. Harris
Journal of International Technology and Information Management
The explosive growth and rapid proliferation of smartphones and other mobile
devices that access data over communication networks has necessitated advocating
and implementing security constraints for the purpose of abetting safe computing.
Remote data access using mobile devices is particularly popular among students at
institutions of higher education. To ensure safe harbor for constituents, it is
imperative for colleges and universities to establish, disseminate, and enforce
mobile device security artifacts, where artifacts is defined as policies, procedures,
guidelines or other documented or undocumented protocols. The purpose of this
study is to explore the existence of, specific content of, and the …
More Secure Passwords, Scott Magruder, Stanley X. Lewis Jr
More Secure Passwords, Scott Magruder, Stanley X. Lewis Jr
Journal of International Technology and Information Management
Passwords are often the first line of defense against hackers trying to logon to a user’s account. Due to this, the password that a user selects for protection of their account is critical. These passwords must be “good” passwords that are not easily cracked. However, how does the network administrator enforce this? A simple change to the login process can make the passwords chosen by users much more secure. A description of this simple process is given in this paper. The normal login process is described. A description of the how hackers attempt to crack passwords is given. The simple …
Improving The Judicial System To Handle Computer Crime, Gerald V. Post, Albert Kagan
Improving The Judicial System To Handle Computer Crime, Gerald V. Post, Albert Kagan
Journal of International Technology and Information Management
This paper asked professionals in the legal system to evaluate the current state and effectiveness of laws to identify and deter computer crime. Responses were evaluated with a formal structural equation model. The results generally show that legal professionals believe potential jurors have minimal knowledge of computer crime issues. More importantly, they also believe that judges have little knowledge or experience. A similar lack of knowledge by defense attorneys indicates that it could be difficult for a person accused of computer related infractions to find adequate representation. On the other hand, more experienced participants do not believe computer laws present …
The Role Of Quantitative Analysis In The Information Security Systems Development Lifecycle, Stephen R. Rosenkranz, Michael E. Busing, Faye P. Teer, Karen A. Forcht
The Role Of Quantitative Analysis In The Information Security Systems Development Lifecycle, Stephen R. Rosenkranz, Michael E. Busing, Faye P. Teer, Karen A. Forcht
Journal of International Technology and Information Management
Today’s numerous Quantitative Analysis (QA) tools have been successfully utilized to solve business problems in diverse applications. However, the application of QA tools in solving information security problems has been sparse. Devising the means and ways to use QA tools in resolving industry-wide security problems has the potential to yield enormous global economic benefit. The purpose of this paper is to explore the use of QA tools as a means of improving the processes involved in the Information Security Systems Development Lifecycle (SecSDL). Information security professionals use the SecSDL as a guide for formulating a comprehensive information security program. The …
