Purpose

Originally the Office of Operations Coordination, the Office of Homeland Security Situational Awareness was established in 2005 with the stated purpose of increasing the Department of Homeland Security's ability to prepare for, prevent, and respond to terrorist attacks and other emergencies and improve coordination and efficiency of operations.^[1]

Today, the Office of Homeland Security Situational Awareness has the stated mission of providing situational awareness, a common operating picture, and decision support for the Homeland Security Enterprise on threats, hazards, and events impacting the homeland. Its responsibilities include:^[2]

• Provides timely, accurate, and coordinated reporting on significant and upcoming DHS operations, operational responses, policy initiatives, and outreach on emerging threats and intelligence assessments.
• Ensures federal resources are coordinated in support of special events throughout the United States, as appropriate.
• Prepares the DHS Crisis Action Team to augment the National Operations Center during significant events.
• Leads the Department's internal Continuity of Operations and Government Programs and critical infrastructure efforts to enable continuation of primary mission essential functions in the event of a degraded and/or crisis operating environment.

Operations

Information is shared and fused on a daily basis by the two halves of the Office, the "Intelligence Side" and the "Law Enforcement Side". The two halves function in tandem. The Intelligence watch floor gathers intelligence and decides how it contributes to the current threats in a given area. The Law Enforcement Side tracks law enforcement activities across the country that may have a terrorist nexus. This information from the two halves accurately depicts the nation's threat environment at any moment.

Through the National Operations Center, the Office provides real-time situational awareness and monitoring of the homeland, coordinates incidents and response activities, and, in conjunction with the Office of Intelligence and Analysis, issues advisories and bulletins concerning threats to homeland security, as well as specific protective measures. The NOC coordinates information sharing to help deter, detect, and prevent terrorist acts and to manage domestic incidents. Information on domestic incident management is shared with Emergency Operations Centers at all levels through the Homeland Security Information Network (HSIN).^[2]
