Abstract This research has been inspired by security concerns due to the recent increase in the terrorist threat to gas and crude oil transportation around the world, especially in regions that are of significant value for the energy supplies. Computational mechanics methods will be used in this research to apply shock wave analysis for possible damage assessment of the affected pipelines. These methods may be also used for pipelines at power plants, which are usually placed high on the homeland security priority list. This study is primarily focused on the behaviour of some type of pipeline elements existing in gas pipeline system which can be subjected to the shock wave produced by the detonation of highly explosive (HE) materials. In this kind of studies the numerical coupling procedure describing interaction between gas and solid domain was implemented. Outcomes of this research are very important in preventing damage progression of pipelines under the blast loading.

AbstractThe cybersecurity of critical infrastructures is an essential topic within national and international security as 16 critical infrastructure sectors touch various aspects of American society. Because the failure to provide adequate cybersecurity controls within the critical infrastructure sectors renders the country open to an attack that could have a debilitating effect on security, national public health, safety, and economic security, this matter is so vital that there is the Presidential Policy Directive (PPD) 21 Critical Infrastructure Security and Resilience advances a national policy to strengthen and maintain secure, functioning and resilient critical infrastructure. An organization identified as the Cybersecurity and Infrastructure Security Agency (CISA) at the Department of Homeland Security (DHS) has the mission to be the risk advisor for the United States (US). Other organizations, such as the National Security Agency (NSA), have approved a specific Knowledge Unit (KU) to address cybersecurity for critical infrastructures associated with doctoral-level granting programs. To address this challenge, it is necessary to identify threats better and defend against them while mitigating risks to an acceptable level. Only then can a nation build a more secure and resilient infrastructure for the future while defending against present-day bad actors as cyberwarfare, cyber espionage, and cybersecurity attacks are the modern-day threats that need to be addressed in planning, designing, implementation, and maintenance. Therefore, the researchers developed a case study reviewing threats against different sectors defined in the PPD.

This work is the result of a research activity started in 2012 to deploy a method for risk assessment to be applied by the Italian Civil Protection and Civil Defence to protect critical infrastructures. The here presented Multi-Risk Assessment Method (MRAM), illustrates the complete approach, provided by this research activity, suitable to estimate both impact and risk in qualitative, semi-quantitative and quantitative fashion for catastrophic or calamitous events, including terrorist non-conventional CBRNe attacks. In the paper a vulnerability reduction assessment methodology is also hinted with an analysis of the relation of MRAM with the USA RAMCAP approach adopted by Department of Homeland Security. The MRAM provides a method for risk assessment, and was also recently implemented in forecasting software tools by some Italian local administrations.
