Covert networks are hidden networks whose users do not disclose their information externally. They use covert channels that are hidden from access controls and security mechanisms, allowing communication to bypass detection. Covert networks employ techniques like steganography to conceal files within other files or messages, and use blind carbon copy to send messages privately to large groups without revealing all email addresses.

2. DEFINITION
Covert Networks are the networks which are
hidden. The users who are participating in the
network does not disclose their information to
the external world.

3. CHARACTERISTICS OF COVERT
NETWORKS
A covert channel is so called because it is hidden
from the access control mechanisms (typically,
read and write), and therefore cannot be
detected or controlled by the security
mechanisms that underlie secure operating
systems.

4. CHARACTERISTICS OF COVERT
NETWORKS
Covert channels are distinct from, legitimate
channel exploitations that attack low-
assurance pseudo-secure systems using
schemes such as steganography.
Steganography is the practice of concealing a
file, message, image, or video within another
file, message, image, or video.
