Description

Please note that the content of this book primarily consists of articles available from Wikipedia or other free sources online. In computer security, a covert channel is a type of computer security attack that creates a capability to transfer information objects between processes that are not supposed to be allowed to communicate by the computer security policy. The term, originated in 1973 by Lampson is defined as " not intended for information transfer at all, such as the service program's effect on system load." to distinguish it from Legitimate channels that are subjected to access controls by COMPUSEC. A covert channel is so called because it is hidden from the access control mechanisms of ultra-high-assurance secure operating systems since it does not use the legitimate data transfer mechanisms of the computer system such as read and write, and therefore cannot be detected or controlled by the hardware based security mechanisms that underlie ultra-high-assurance secure operating systems.show more
