Critical infrastructure

Critical Infrastructure (CI) is very important because the nation relies on it to carry out its essential activities. Since there are many essential activities that must be carry out at all times across the nation, CI has been divided into 16 different CI sectors (Department of Homeland Security, 2017). While each sector is different and perform different functions, all CI sectors are interdependent. That means that each CI sector relies on the functions of other CI sector(s) in order to be able to carry out their functions. That is why all CI Sectors are equally important because the disruption of one CI sector could also lead to the disruption of another or multiple CI sectors. Therefore, Critical Infrastructure Protection (CIP) is a vital component of many homeland security strategies. CIP efforts are mainly driven by Presidential Policy Directive (PPD) 21 as well as by the National Infrastructure Protection Plan (NIPP) (Hemme, 2015).…

There are sixteen segments that make up the critical infrastructure of United States.

Critical Infrastructure is a term used to describe assets that are essential for the functioning of a society and economy, the infrastructure. The systems and networks that make up this infrastructure are often taken for granted, and a disruption to one of these systems will have dire consequences across other sectors. There are 16 critical infrastructure sectors in the United States whose assets, systems, and networks are vital to our security, national economic security, national public health…

A Case Study of the United States Critical Infrastructure There are services within every society that acts as the life force behind its success; whether rudimentary or advanced these services are employed in order to maintain a functional nation. The United States of America is no different, several systems and assets support our nation by providing essential services from water supply, economic, healthcare, communication and transportation (Critical Infrastructure Sectors, 2015). Whether…

business needs. The collaborative emphasis advanced by this Act would have mitigated and facilitated establishment of a more resilient cybersecurity posture. As far as the critical infrastructure is concerned, the proposed Act recognizes the dependency of the government on the private sector for critical infrastructure and services and calls for collaboration with the private sector to determine cybersecurity performance requirements.

Decision Directive 63 which established the United States critical infrastructure program as applicable to computer and information systems. Subsequently, in 2002 the Federal Information Security Management Act (FISMA) replaced the Computer Security Act of 1987 which intended to enhance information security policies in federal offices. In the end, in 2013 President Barrack Obama signed Executive Order 13636 which led NIST publishing the Cybersecurity Framework version 1.0 which is applicable to…

Homeland Security and Critical Infrastructure The events of September 11, 2001, highlighted significant gaps in the country’s emergency preparedness and more specifically, its ability to identify threats and protect against terrorist attacks.

A program that would improve the…

As preparation infrastructure improves, society can address broader ranges of risks, resulting in a better prepared society. In that sense, regardless of whether society is well prepared, the Preparation phase sets the stage for the Response…

the form of network interference through the injection of ad-hoc crafted streams of packets designed to flood the network. Another form is single implementation vulnerability in which the goal is to exploit an irregularity of a particular model of network devices caused by implementation errors. Fortunately, the known threats or possible threats are considered in creating countermeasures (López, Setola, & Wolthusen, 2012, p. 224-226). Countermeasures are unequivocally essential to maintain…
