Dhaka is the capital of Bangladesh and the principal city of Dhaka District. Dhaka is a Mega city and one of the major cities of the South Asia. Located on the banks of the Buriganga River, Dhaka, along with its metropolitan area, has a population of over 12 million, making it the largest city in Bangladesh.[1] With its colourful history, Dhaka is known as the 'City of Mosques' and for its famous fine Muslin cloth which has a great ethnic value. Under Mughal rule in the 17th century, the city was also known as Jahangir Nagar, and was both a provincial capital and a centre of the world-wide muslin trade. The modern city, however, was developed chiefly under British rule in the 19th century, and soon became the second-largest city in Bengal after Calcutta (presently Kolkata). With the partition of India in 1947, Dhaka became the administrative capital of East Pakistan, and later, in 1972, the capital of an independent Bangladesh. During the intervening period, the city witnessed widespread turmoil; this included many impositions of martial law, the declaration of Bangladesh's independence, military suppression, devastation during war, and natural calamities. Modern Dhaka is the centre of political, cultural and economic life in Bangladesh. Its urban infrastructure is the most developed in the country, it is nonetheless a fighting metropolitan city with challenges such as pollution, congestion, and lack of adequate services due to the rising population. In recent decades, Dhaka has seen modernisation of transport, communications and public works. The city is attracting large foreign investments and greater volumes of commerce and trade. It is also experiencing an increasing influx of people from across the nation. To fight rising traffic congestion and population rise in the capital city, the national government has implemented a policy for rapid urbanisation of surrounding areas and beyond by recent introduction of ten year tax on income holiday for new construction of all types of facilities and buildings outside Dhaka.

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.
