1. Security Level 1 requires that appropriate, minimal protective and security measures are always maintained.
2. Security Level 2 involves maintaining additional protective and security measures for a period due to an increased risk of a security-related incident.
3. Security Level 3 means that further specific protective and security measures must be maintained for a limited period when a security-related incident is probable or imminent, even if the specific target may not be identifiable.
