Homeland security field deals with diverse subjects, audio processing, video surveillance, image detection, geolocation determination, and cyber attack detection. Audio processing and video surveillance area are significant for public places safety and land border area. However the big threat for homeland security is cyber attacks. Cyber terror attacks and cyber crime attacks may move over virt...

The concept of a common operational picture has been utilized by the military for situational awareness in warfare domains for many years. With the emergence of cyberspace as a domain, there is a necessity to develop doctrine and tools to enable situational awareness for key-decision makers. Our study analyzes key elements that define cyber situational awareness to develop a methodology to iden...

1. Project Goals ● Develop a resilient cyber-physical control strategy for FREEDM system to secure the energy scheduling and physical operation: ○ Extending to cyber-physical security: Explore possible attacks on both energy scheduling and physical operation, analyze the impacts in terms of economic benefit and system stability. ○ Interaction between cyber/physical layer detection: Investigate ...

Permission has been given to destroy this document when it is no longer needed. Cyber-enabled and cyber-physical systems connect and engage virtually every mission-critical military capability today. And as more warfighting technologies become integrated and connected, both the risks and opportunities from a cyberwarfare continue to grow—motivating sweeping requirements and investments in cyber...

Cyber Security plays an important role in the development of information technology as well as Internet services. Our attention is usually drawn on “Cyber Security” when we hear about “Cyber Crimes”. Our first thought on “National Cyber Security” therefore starts on how good is our infrastructure for handling “Cyber Crimes” [1]. This paper focus on cyber security emerging trends while adopting ...

Studying models of cyber epidemics over arbitrary complex networks can deepen our understanding of cyber security from a whole-system perspective. In this paper, we initiate the investigation of cyber epidemic models that accommodate the dependences between the cyber attack events. Due to the notorious difficulty in dealing with such dependences, essentially all existing cyber epidemic models h...

The current research used meta-analysis to determine whether (a) sex differences emerged in cyber-bullying frequency, (b) if age moderated any sex effect, and (c) if any additional moderators (e.g., publication year and status, country and continent of data collection) influenced the sex effect. Theoretically, if cyber-bullying is considered a form of traditional bullying and aggression, males ...

The aim of this study was to investigate the association of personality (Five Factor Model), coping and cyber-bullying/victimization experiences among 300 Greek pre-adolescent students attending the upper two primary school grades. Boys reported more frequent involvement in cyber-bullying incidents, while there were no significant gender differences in terms of cyber-victimization. In terms of ...

State estimation is used in power systems to estimate grid variables based on meter measurements. Unfortunately, power grids are vulnerable to cyber-attacks. Reducing cyber-attacks against state estimation is necessary to ensure power system safe and reliable operation. False data injection (FDI) is a type of cyber-attack that tampers with measurements. This paper proposes network reconfigurati...

In this paper, we describe Jack-in-the-Net (Ja-Net) architecture for service emergence and evolution in a large scale, open network environment. In Ja-Net, a service is implemented by a collection of cyber-entities and provided through cooperative interaction of cyber-entities. Cyber-entities interact with each other using Ja-Net ACL (Agent Communication Language). To ensure that service compos...
