Enclose a small form factor, passively cooled, low power, computer in a enclosure made to block all covert communication that silicon trojans inside the CPU could use. No, a faraday cage does not work against all (very large) wavelengths, so absorbing is better.

Doubles down as protection layer against electromagnetic damage.

Once I confirm this works, I will build living quarters equally protected at all sides. Protects the brain equally.
