With the ongoing increase of threats and vulnerabilities to our information security, the need for a strong, secure and an effective kind of approach is highly required. An approach that fulfills all these parameters is a byproduct of the trending steganography technique. As there is the availability of various types of cover media, but this paper focuses only on one such media, which is a 'network'. Using the network as the cover media for hiding the data for transmission of the secret information safely, is one of the smart moves towards the information security. This approach is known as network steganography. Since the intruders try every bit to take the advantage of that secret information, this concept of network steganography provides the concealment of the secret data by using the covert channel which uses the bandwidth of other permissible communication channels for the transmission purpose. This paper is on network steganography depicting all the proposed methods available for the network steganography along with the process of concealing the secret information in the desired communication protocol.

“…After a dummy packet is received, the mismatch between the hidden sender and hidden receiver takes place. To negotiate this fact SOF packets [25] are utilized after transferring T − 1 packets within a covert channel. A receiver fixes T −1 packets gained after SOF packet and waits for the next SOF packet.…”

Abstract-This paper observes different methods for network covert channels constructing and describes the scheme of the packet length covert channel. The countermeasure based on random traffic padding generating is proposed. The capacity of the investigated covert channel is estimated and the relation between parameter of covert channel and counteraction tool is examined. Practical recommendation for using the obtained results are given.

“…Thereby, the existence of monitors in the targeted network can be compromised. To this end, the PN-code-based steganographic attack presented in our paper can be understood as a covert channel problem [10], because the attack traffic encoded by a signal blends into the background traffic and is only recognizable by the attacker which knows the secret pattern of the PN code.…”
