Bump-in-the-wire (BITW) is a communications device which can be inserted into existing (legacy) systems to enhance the integrity, confidentiality, or reliability of communications across an existing logical link without altering the communications endpoints. The term was originally used to indicate that the device should introduce only a relatively small increased latency in communications compared to the original, unsecured, approach.
