Covert channels are used for the secret transfer of information. Now a day’s covert channel it is an
interesting study area. A Covert channel can be used to pass a wicked message. The message can be any form such as
computer virus, spy programs, terrorist messages etc. A Covert channel is defined as it is a way of abstracting the
information and hiding the information, in such a way that the person who reads should not examine the hidden
information and transmits the data to the destination. A covert channel uses the different field to hide the data. In this
paper, we use the different network protocol of OSI model. This paper presents the basis for the development of a toolkit
for creating and exploiting hidden channels within the standard design of network communication protocols. The data
can be wicked software or virus that can be communicated through the unauthorized channel. This paper focuses on the
methods of hiding and countermeasures.
