Critical infrastructure is vital for essential functioning of a country. Incidental or deliberate damage will have serious impact on the economy as well as providing essential services to the communities it serves. There are a number of reasons why infrastructure needs to be heavily secured and protected.
One of the fundamental foundations of modern society is the electrical power systems. An intentional disruption of electricity supplies would affect national security, the economy, and every person's life. Because power grids and their sources are widely dispersed, this is a challenge for the effectiveness of defensive organizations and structures.7
Sabotage can damage electrical sources for the power grid, including civilian nuclear power stations. Sabotage in the form of cyberattacks can create havoc with computer, communication, and information systems, which could severely interrupt the electrical supply. This in turn can cause major disruptions to other infrastructure components of society. Comprehensive defense plans are proposed.8
One method is to isolate load systems. Sophisticated defense systems should be wide-area, real-time protection, with control systems that are alerted and guided by sensing technologies. Communication and information must be capably routed.9
Many countries have initiated government agencies to directly manage the security of critical infrastructure usually through the Ministry of Interior/Home Affairs, dedicated security agencies to protect facilities such as United States Federal Protective Service, as well as dedicated transport police such as the UK's British Transport Police and Amtrak Police in the United States.
A number of government organizations focus on infrastructure security and protection. In the USA, the Technical Support Working Group has the Infrastructure Protection Subgroup. The UK has the National Infrastructure Security Co-ordination Centre.
Critical infrastructure sites may deploy perimeter intrusion detection systems, video surveillance, access control and other security systems to detect and respond to intruders and other security events. Meanwhile, maritime and offshore critical infrastructure sites can benefit from the deployment of satellite imagery, sensors, advanced patrol aircraft, autonomous underwater vehicles and anti-drone capabilities, among other solutions.10
