Infrastructure
Infrastructure is the fundamental facilities and systems serving a country, city, or other area, including the services and facilities necessary for its economy to function. Infrastructure is composed of public and private physical improvements such as roads, bridges, tunnels, water supply, sewers, electrical grids, telecommunications (including Internet connectivity and broadband speeds). In general, it has also been defined as "the physical components of interrelated systems providing commodities and services essential to enable, sustain, or enhance societal living conditions."
Security
Security is freedom from, or resilience against, potential harm (or other unwanted coercive change) from external forces. Beneficiaries (technically referents) of security may be persons and social groups, objects and institutions, ecosystems, and any other entity or phenomenon vulnerable to unwanted change by its environment.
Security
To bargain freedom for security is the devil's bargain. Having made the bargain, one enjoys neither freedom nor security.
Gerry Spence, Give Me Liberty! Freeing Ourselves in the Twenty-First Century, Ch. 16 : Security, the One-Way Ticket to Slavery, p. 174 (1998)
Security
No nation can make itself secure by seeking supremacy over all others. We all share responsibility for each other’s security, and only by working to make each other secure can we hope to achieve lasting security for ourselves.
Kofi Annan, Address at the Truman Presidential Museum and Library, Independence, Missouri, USA (11 December 2006)
Security
[T]he production of security should, in the interests of the consumers of this intangible commodity, remain subject to the law of free competition. … [N]o government should have the right to prevent another government from going into competition with it, or to require consumers of security to come exclusively to it for this commodity.
Gustave de Molinari, tr. J. Huston McCulloch, §II of The Production of Security (Auburn, AL: Ludwig von Mises Institute, 2009; orig. 1849), pp. 22–23.
