Amsterdam is the capital and largest city of the Netherlands, located in the province of North Holland in the west of the country. The city, which had a population of 747,290 on 1 January 2008, comprises the northern part of the Randstad, the 6th-largest metropolitan area in Europe, with a population of around 6.7 million. Its name is derived from Amstel dam, indicative of the city's origin: a dam in the river Amstel where the Dam Square is today. Settled as a small fishing village in the late 12th century, Amsterdam became one of the most important ports in the world during the Dutch Golden Age, a result of its innovative developments in trade. During this time, the city was the leading centre for finance and diamonds. In the 19th and 20th centuries, the city expanded and many new neighbourhoods and suburbs were formed. The city is the financial and cultural capital of the Netherlands. Many large Dutch institutions have their headquarters there, and 7 of the world's top 500 companies, including Philips and ING, are based in the city. The Amsterdam Stock Exchange, part of Euronext, is located in the city centre. Amsterdam's main attractions, including its historic canals, the Rijksmuseum, the Van Gogh Museum, its red-light district and its many cannabis coffee shops, draw 4.2 million tourists annually.

Cyberwarfare

Cyberwarfare refers to politically motivated hacking to conduct sabotage and espionage. It is a form of information warfare sometimes seen as analogous to conventional warfare although this analogy is controversial for both its accuracy and its political motivation.

Cyberwarfare has been defined by government security expert as actions by a nation-state to penetrate another nation's computers or networks for the purposes of causing damage or disruption. The Economist describes cyberwarfare as the fifth domain of warfare, and William J. Lynn, U.S. Deputy Secretary of Defense, states that as a doctrinal matter, the Pentagon has formally recognized cyberspace as a new domain in warfare which has become just as critical to military operations as land, sea, air, and space.

In 2009, President Barack Obama declared America's digital infrastructure to be a strategic national asset, and in May 2010 the Pentagon set up its new U.S. Cyber Command (USCYBERCOM), headed by General Keith B. Alexander, director of the National Security Agency (NSA), to defend American military networks and attack other countries' systems. The United Kingdom has also set up a cyber-security and operations centre based in Government Communications Headquarters (GCHQ), the British equivalent of the NSA. In the U.S. however, Cyber Command is only set up to protect the military, whereas the government and corporate infrastructures are primarily the responsibility respectively of the Department of Homeland Security and private companies. Cyber warfare is the least common type of warfare and has not been used effectively to date.

In February 2010, top American lawmakers warned that the threat of a crippling attack on telecommunications and computer networks was sharply on the rise. According to The Lipman Report, numerous key sectors of the U.S. Economy along with that of other nations are currently at risk, including cyber threats to public and private facilities, banking and finance, transportation, manufacturing, medical, education and government, all of which are now dependent on computers for daily operations. In 2009, President Obama stated that cyber intruders have probed our electrical grids.

The Economist writes that China has plans of winning informationised wars by the mid-21st century. They note that other countries are likewise organizing for cyberwar, among them Russia, Israel and North Korea. Iran boasts of having the world's second-largest cyber-army. James Gosler, a government cybersecurity specialist, worries that the U.S. has a severe shortage of computer security specialists, estimating that there are only about 1,000 qualified people in the country today, but needs a force of 20,000 to 30,000 skilled experts. At the July 2010 Black Hat computer security conference, Michael Hayden, former deputy director of national intelligence, challenged thousands of attendees to help devise ways to reshape the Internet's security architecture, explaining, You guys made the cyberworld look like the north German plain.
