Machines / Networked devices Process numeric Threshold data Extremely well… Semantic information e.g., “guarded” Not so

1. Threat Level minimal Precedence is a simple ordering, based on either importance or sequence: Message precedence of military communications traffic Order of precedence, the (ceremonial) hierarchy within a nation or state Order of operations, in mathematics and computer programming CAP XML Alert Level Increase… Machines / Networked devices Process numeric Threshold data Extremely well… Semantic information e.g., “guarded” Not so much… 0,1,2,3,4 CCEB military precedence: The Combined Communications-Electronics Board (CCEB), a five-nation joint military communications-electronics organization (consisting of Australia, Canada, New Zealand, the United Kingdom, and the United States), uses the following message precedence designators, in descending order of PRECEDENCE: 0, 1, 2 INFOCON levels: NORMAL /ALPHA (increased), BRAVO (specific risk of attack), CHARLIE (limited attack), DELTA (general attack).
