The white house has just recently approved the usage of a simple cyber security threat chat. I doubt we will see a 1984 doomsday clock style report anytime soon. This will be used mostly internally and the people will probably never know what the threat level is on.

 

These are the determining factors to the chart,

• The severity of a given incident;

• The urgency required for responding to a given incident;

• The seniority level necessary for coordinating response efforts; and

• The level of investment required of response efforts
