Legal Definitions - Information Analysis and Infrastructure Protection Directorate

The Information Analysis and Infrastructure Protection Directorate (IAIP) is a division of the U.S. Department of Homeland Security. Its main responsibility is to analyze intelligence information from various sources, such as the Central Intelligence Agency, the Defense Intelligence Agency, the Federal Bureau of Investigation, and the National Security Administration. The IAIP issues warnings about potential terrorist attacks and evaluates weaknesses in the nation's infrastructure to recommend ways to reduce vulnerability to attacks.

For example, the IAIP may analyze intelligence information about a potential terrorist attack on a major airport. They would then issue a warning to the airport and recommend ways to increase security measures to reduce the risk of an attack.

Another example is if the IAIP identifies a weakness in the nation's power grid that could be exploited by terrorists. They would then recommend ways to strengthen the power grid to reduce the risk of an attack that could cause widespread power outages.
