In the post-9/11 world, the possibility of energy infrastructure-terrorism—the use of weapons to cause devastating damage to the energy industrial sector and cause cascading effects—is very real. Energy Infrastructure Protection and Homeland Security, Second Edition, is a reference for those involved with our energy infrastructure who want quick answers to complicated questions. It is intended to help employers and employees handle security threats they must be prepared to meet on a daily basis.
