covert channel

1. A transmission channel that may be used to transfer data in a manner that violates security policy. [2382-pt.8] 2. [An] unintended and/or unauthorized communications path that can be used to transfer information in a manner that violates an information system (IS) security policy. [INFOSEC-99]   3.  A channel which allows information to flow in violation of the System Security policy.  Note: Covert channels can occur via mechanisms other than explicitly designed channels. For example, a covert timing channel may transmit information by inducing variations in system response time   [CESG].  4. The use of a mechanism not intended for communication to transfer information in a way which violates security [ITSEC].  5.  A communications channel that allows a process to transfer information in a manner that violates the system's security policy. A covert channel typically communicates by exploiting a mechanism not intended to be used for communication [POSIX.6].  6.  A communications channel that allows a process to transfer information in a manner that violates the system's security policy.  See also: Covert Storage Channel, Covert Timing Channel [TCSEC].
