A user interface facilitates assessing security risks for linear corridors. The interface includes a navigation window presenting geospatial data for an area associated with a corridor. The interface also includes a navigation tool having a corridor indicator that provides a diagrammatic linear representation of the linear corridor, indicia along the corridor indicator that represent critical assets, and a corridor window superimposed on the corridor indicator that slides linearly along the corridor indicator. The portion of the corridor displayed in the interface corresponds to a location of the corridor window on the corridor indicator. The interface also includes an attributes area presenting information associated with the area presented in the navigation window. At least one of the navigation window and the attributes area is configured to present risk assessment information associated with the linear corridor.
