The importance of face-to-face informal communication is well recognized. The ‘irori’ is a Japanese-traditional little sitting space or room with a fire burning which affords relaxation and intimacy among a family. We, adopting the ‘irori’ as a metaphor, have designed and developed a cyber-space called IRORI as an IT-based space that catalyzes face-to-face informal communication among members o...

Abstract—Cyber exercises used to assess the preparedness of a community against cyber crises, technology failures and Critical Information Infrastructure (CII) incidents. The cyber exercises also called cyber crisis exercise or cyber drill, involved partnerships or collaboration of public and private agencies from several sectors. This study investigates Organisation Cyber Resilience (OCR) of p...

E cyber threats in a contested environment provide a challenge in protecting operations and critical assets. Traditional cyber protection mechanisms can prove ineffective when facing a motivated, well-resourced adversary. As a result, many mission critical systems remain vulnerable to advanced, targeted cyber attacks despite the significant amount of effort and resources used to secure them. Co...

As threats against digital assets have risen and there is necessitate exposing and eliminating hidden risks and threats. The ability of exposing is called “cyber forensics.” Cyber Penetrators have adopted more sophistical tools and tactics that endanger the operations of the global phenomena. These attackers are also using anti-forensic techniques to hide evidence of a cyber crime. Cyber forens...

In this paper, we presented a new model for cyber crime investigation procedure which is as follows: readiness phase, consulting with profiler, cyber crime classification and investigation priority decision, damaged cyber crime scene investigation, analysis by crime profiler, suspects tracking, injurer cyber crime scene investigation, suspect summon, cyber crime logical reconstruction, writing ...

Background: The Cyber Preparedness Continuum CNA’s Safety and Security Division conducted a Cyber Preparedness Workshop on April 25, 2013, at CNA’s headquarters in Alexandria, Virginia. The workshop brought together emergency management and cybersecurity stakeholders, drawn from both the public and private sectors, to discuss cyber preparedness. Discussions during the workshop centered around t...

This paper describes AMICA (Analyzing Mission Impacts of Cyber Actions), an integrated approach for understanding mission impacts of cyber attacks. AMICA combines process modeling, discrete-event simulation, graph-based dependency modeling, and dynamic visualizations. This is a novel convergence of two lines of research: process modeling/simulation and attack graphs. AMICA captures process flow...
