1. A security apparatus, comprising:

  • a transmitter configured to transmit acoustic signals in a computing system according to an acoustic pattern;

    a receiver configured to receive returned acoustic signals in response to the transmitted acoustic signals;

    a logic configured to;

    upon receiving the returned acoustic signals at the receiver, generate acoustic measurements from the returned acoustic signals based on the acoustic pattern, the generated acoustic measurements relating to a physical arrangement of computing components within the computing system;

    compare the generated acoustic measurements to baseline acoustic measurements, wherein the baseline acoustic measurements are derived from acoustic profiles corresponding to a default physical arrangement of computing components within the computing system; and

    upon determining that the generated acoustic measurements do not substantially match the baseline acoustic measurements, assert a signal indicating that the default physical arrangement of computing components within the computing system has been altered.
