identified as a(n)?
A.
Covert channel
B.
Overt channel
C.
Opened channel
D.
Closed channel
Explanation:
An overt channel is a path within a computer system or network that is designed for the authorized transfer of
data. The opposite would be a covert channel which is an unauthorized path. A covert channel is a way for an
entity to receive information in an unauthorized manner. It is an information flow that is not controlled by a
security mechanism. This type of information path was not developed for communication; thus, the system
does not properly protect this path, because the developers never envisioned information being passed in this
way. Receiving information in this manner clearly violates the system’s security policy.
