Contributor(s): Michael Chertoff | In this lecture former US Secretary of Homeland Security Michael Chertoff will address changes in home security challenges at the tenth anniversary of 9/11 and in the wake of the death of Bin Laden. This will include the new networked structure of terrorism, the increasing challenge of homegrown terrorism, and cybersecurity. As Secretary of the U.S. Department of Homeland Security from 2005 to 2009, Mr Chertoff led the country in blocking would-be terrorists from crossing US borders or implementing their plans if they were already in the country. He also transformed FEMA into an effective organization following Hurricane Katrina. His greatest successes have earned few headlines – because the important news is what didn't happen. As co-founder and managing principal at Chertoff Group, Mr Chertoff provides high-level strategic counsel to corporate and government leaders on a broad range of security issues, from risk identification and prevention to preparedness, response and recovery. Before heading up the Department of Homeland Security, Mr Chertoff served as a federal judge on the U.S. Court of Appeals for the Third Circuit. Earlier, during more than a decade as a federal prosecutor, he investigated and prosecuted cases of political corruption, organised crime, corporate fraud and terrorism – including the investigation of the 9/11 terrorist attacks. Chertoff spent one year of his studies at LSE and is a magna cum laude graduate of Harvard College (1975) and Harvard Law School (1978). From 1979-1980 he served as a clerk to Supreme Court Justice William Brennan, Jr. In addition to his role at Chertoff Group, Mr. Chertoff is also senior counsel at Covington & Burling LLP, and a member of the firm's White Collar Defense and Investigations practice group.
