Nonetheless, an identified operative must be cut off from access to further secure information, without letting him know that his [[Cover (intelligence)|cover]] is blown, then fed an elaborate stream of credible [[disinformation]]. Then an assessment must be made as to the extent of the damage and what information has been compromised. Eventually, the mole and his handlers will realize their operation has been compromised because of the useless disinformation being passed; but this step buys time for the difficult process of "walking the dog backwards" to determine what has been compromised within the target organization. That is the point at which an arrest is usually made. Sometimes, however, the process of feeding disinformation can be useful, so a discovered agent may be left in place for years. | Nonetheless, an identified operative must be cut off from access to further secure information, without letting him know that his [[Cover (intelligence)|cover]] is blown, then fed an elaborate stream of credible [[disinformation]].
