Calcutta is the capital of the Indian state of West Bengal. It is located in eastern India on the east bank of the River Hooghly. When referred to as "Kolkata", it usually includes the suburbs, and thus its population exceeds 15 million, making it India's third-largest city and urban agglomeration. Calcutta served as the capital of India during the British Raj until 1911. Once the centre of modern education, industry, science, culture and politics in India, Kolkata has witnessed intense political violence, clashes and economic stagnation since 1954. Since the year 2000, economic rejuvenation has spurred in the city's growth. Like other metropolitan cities in India, Kolkata continues to struggle with the problems of urbanisation: poverty, pollution and traffic congestion. Kolkata is noted for its revolutionary history, ranging from the Indian struggle for independence to the leftist and trade union movements.

Cyber Espionage

Cyber espionage is the act or practice of obtaining secrets (sensitive, proprietary or classified information) from individuals, competitors, rivals, groups, governments and enemies also for military, political, or economic advantage using illegal exploitation methods on internet, networks, software and or computers. Classified information that is not handled securely can be intercepted and even modified, making espionage possible from the other side of the world. See Titan Rain and Moonlight Maze. General Alexander notes that the recently established Cyber Command is currently trying to determine whether such activities as commercial espionage or theft of intellectual property are criminal activities or actual breaches of national security.

Sabotage

Military activities that use computers and satellites for coordination are at risk of equipment disruption. Orders and communications can be intercepted or replaced. Power, water, fuel, communications, and transportation infrastructure all may be vulnerable to disruption. According to Clarke, the civilian realm is also at risk, noting that the security breaches have already gone beyond stolen credit card numbers, and that potential targets can also include the electric power grid, trains, or the stock market.
