Lagos is the most populous conurbation in Nigeria with 7,937,932 inhabitants at the 2006 census. It is the most populous in Africa, and currently estimated to be the second fastest growing city in Africa (7th fastest in the world), immediately following Bamako. Formerly the capital of Nigeria, Lagos is a huge metropolis which originated on islands separated by creeks, such as Lagos Island, that fringe the southwest mouth of Lagos Lagoon, protected from the Atlantic Ocean by long sand spits such as Bar Beach which stretch up to 100 km east and west of the mouth. From the beginning, Lagos has spread on the mainland west of the lagoon and the conurbation, including Ikeja and Agege, now reaches more than 40 km north-west of Lagos Island. The city is the economic and financial capital of Nigeria.

Electrical Power Grid Cyber Security

The federal government of the United States admits that the electric power transmission is susceptible to cyberwarfare. The United States Department of Homeland Security works with industry to identify vulnerabilities and to help industry enhance the security of control system networks, the federal government is also working to ensure that security is built in as the next generation of smart grid networks are developed. In April 2009, reports surfaced that China and Russia had infiltrated the U.S. electrical grid and left behind software programs that could be used to disrupt the system, according to current and former national security officials. The North American Electric Reliability Corporation (NERC) has issued a public notice that warns that the electrical grid is not adequately protected from cyber attack. China denies intruding into the U.S. electrical grid.89 One countermeasure would be to disconnect the power grid from the Internet and run the net with droop speed control only. Massive power outages caused by a cyber attack, could disrupt the economy, distract from a simultaneous military attack, or create a national trauma.
