Washington: Learning a lesson from the 2008 Mumbai attacks, several American security and intelligence agencies have conducted a series of workshops in six major US cities to tackle such terror strikes, US Homeland Security department has said.

The information on preparations made to prevent Mumbai-type terrorist attacks has been provided by the Department of Homeland Security (DHS) in its annual budgetary proposals to the Congress.

"To address the current threat environment, FEMA partnered with the DHS Office of Intelligence and Analysis, the National Counter-terrorism Center, and the Department of Justice/ Federal Bureau of Investigation to conduct in six major cities across the country a series of workshops focused on response to a Mumbai-style terror attack," it said.

While names of the cities have not been released, reports in the past have indicated them to include New York, Los Angeles, Chicago and Washington.

DHS said that the New York Police Department (NYPD) had sent its team on the ground even as the Pakistan-based terrorists were carrying out mayhem in Mumbai in November 2008.

It said that it had signed a MoU with India last year to ensure the timely exchange of critical cyber security information and expertise between the two governments through the Indian Computer Emergency Response Team and DHS' United States Computer Emergency Readiness Team (US-CERT).

Through this arrangement, the governments and the cyber security community of the countries will have the ability to coordinate with their counterparts on a broad range of technical and operational cyber issues, it said in the budgetary proposal.

Referring to last year's India visit of the Secretary of Homeland Security Janet Napolitano, the department said the US launched the Homeland Security Dialogue with India – the first comprehensive bilateral dialogue on homeland security issues between the two countries.

Focus was on securing the global supply chain, trafficking of illicit goods and materials, and protection of critical cyber infrastructure, it said.
