RED/BLACK Separation
TEMPEST standards require "RED/BLACK separation", i.e. maintaining distance or installing shielding between circuits and equipment used to handle plaintext classified or sensitive information (RED) and normal unsecured circuits and equipment (BLACK), the latter including those carrying encrypted signals. Manufacture of TEMPEST-approved equipment must be done under careful quality control to ensure that additional units are built exactly the same as the units that were tested. Changing even a single wire can invalidate the tests.

“Swift blazing flag of the regiment,
Eagle with crest of red and gold,
These men were born to drill and die.
Point for them the virtue of slaughter,
Make plain to them the excellence of killing
And a field where a thousand corpses lie.”

“Mighty few young black women are doin’ domestic work. And I’m glad. That’s why I want my kids to go to school. This one lady told me, “All you people are gettin’ like that.” I said, “I’m glad.” There’s no more gettin’ on their knees.”
—Maggie Holmes, African American domestic worker. As quoted in Working, book 3, by Studs Terkel (1973)
