Today’s society is more complicated than ever before, with people dependent on complex infrastructures, traveling widely, and gathering in crowded places. Recent history teaches us that terror can suddenly disrupt our lives, striking anywhere and anytime. This is the challenge to homeland security and it has never been greater: We need better means to prevent and respond to physical and cyber terror – and crime and natural disaster too – and better ways to maintain public order in time of emergency. The 2nd International Conference on Homeland Security was created to address these challenges. It will bring together government officials, public authorities and HLS industry leaders from around the world to share their knowledge and experience. Israel HLS 2012 will focus on today’s key homeland security issues: Cyber security, securing smart cities, critical infrastructure protection and emergency preparedness. Attendees will learn how to enhance security by integrating operational know-how with the advanced tools necessary to deal with emerging threats.
