Tempest

Tempest is a NATO-certification that includes both protection against compromising emanations, and methods to eavesdrop upon others to disclose confidential information.

Tempest as a form of protection is normally applied to environments and devices which are considered highly vulnerable. Thus, tempest-certified equipment come with the most severe protection against compromising emanations.

Three levels of Tempest standard NATO SDIP-27

Three different tempest standards can be defined. These are level A, B and C.

Level A
The tempest standard Level A is the strictest NATO-standard and is sometimes therefore referred to as ”Full”. This standard is thus for devices that are operated within the NATO Zone 0.

Level B
The tempest standard Level B is the next strictest NATO-standard, sometimes referred to as ”Immediate”. This tempest standard is therefore for devices that are operated within the NATO Zone 1.

Level C
The tempest standard level C is sometimes referred to as ”Tactical”. This standard is applied to environments and devices within the NATO Zone 2.
