Homeland Security Vulnerability Assessments

Decent Essays

One of the Department of Homeland Security’s (DHS) most important missions is protecting critical infrastructure. Assessing CI vulnerabilities is critical to strengthening their capabilities and ensuring resiliency. Since most of them are privately owned, the Department partners with the private sector in conducting voluntary, non-regulatory vulnerability assessments (“Critical Infrastructure”, 2015). According to Homeland Security (2015), vulnerability assessments are the foundation National Infrastructure Protection Plan (NIPP) which outlines how the government and the private sector work together to manage risks to achieve security and resiliency goals (“Critical Infrastructure”, 2015). Protecting America’s electrical power grid is especially complicated because all of the other CIs depend on the energy sector’s …show more content…

Managing these risks involves developing approaches that result in sound, scenario-based consequence and vulnerability estimates as well as assessments of the likelihood that the suggested threat will occur (“Executing A Critical”, n.d.). Risk is influenced by the nature and magnitude of a hazard or threat, the vulnerabilities to the threat or hazard, and possible consequences (“Executing A Critical”, n.d.). The threat landscape of the electric utility subsector includes physical attacks/theft, cyber-attack, natural disaster, and nuclear attacks (“Addressing Dynamic”, 2014). In addition to these threats and vulnerabilities, the subsector has identified other key issues and risks such as workforce capability and human errors, equipment failure and aging infrastructure, and evolving environmental, economic, and reliability regulatory requirements (“Energy Sector”, 2015). Electricity assets are numerous including residential homes, commercial offices, utility companies, transmission lines, etc. and their locations vary across the
