Assessing the Risks of Cyber Terrorism, Cyber War and Other Cyber Threats

Cyber attacks, network security and information pose complex problems that reach into new areas for national security and public policy. This paper looks at one set of issues – those related to cyber-terrorism and cyber attacks on critical infrastructure and their implications for national security. Cyber-terrorism is “the use of computer network tools to shut down critical national infrastructures (such as energy, transportation, government operations) or to coerce or intimidate a government or civilian population.” The premise of cyber terrorism is that as nations and critical infrastructure became more dependent on computer networks for their operation, new vulnerabilities are created – “a massive electronic Achilles' heel.” A hostile nation or group could exploit these vulnerabilities to penetrate a poorly secured computer network and disrupt or even shut down critical functions.
