Covert Channels
  • Unintended and/or unauthorized communications path that can be used to transfer information in a manner that violates an AIS security policy. (Source: NSTISSI 4009). Note: Covert channels may be storage or timing channels. A covert storage channel involves the direct or indirect writing to a storage location by one process and the direct or indirect reading of the storage location by another process. A covert timing channel is one in which one process signals information to another process by modulating its own use of system resources in such a way that this manipulation affects the real response time observed by the second process. (Source: NCSC-TG-029).
