Security Environment Threat List

Overview
The Security Environment Threat List (SETL) is

"A list of countries with United States (U.S.) Diplomatic Missions compiled by the Department of State (DOS) and updated semi-annually. The listed countries are evaluated based on transnational terrorism; political violence; human intelligence; technical threats; and criminal threats. The following four threat levels are based on these evaluations:

• Critical: A definite threat to U.S. assets based on an adversary's capability, intent to attack, and targeting conducted on a recurring basis. • High: A credible threat to U.S. assets based on knowledge of an adversary's capability, intent to attack, and related incidents at similar facilities. • Medium: A potential threat to U.S. assets based on knowledge of an adversary's desire to compromise the assets and the possibility that the adversary could obtain the capability to attack through a third party who has demonstrated such a capability. • Low: Little or no threat as a result of the absence of credible evidence of capability, intent, or history of actual or planned attack against U.S. assets."
