-In this paper we propose a new method for the evaluation of network steganography algorithms based on the new concept of "the moving observer". We considered three levels of undetectability named: "good", "bad", and "ugly". To illustrate this method we chose Wi-Fi steganography as a solid family of information hiding protocols. We present the state of the art in this area covering well-known hiding techniques for 802.11 networks. "The moving observer" approach could help not only in the evaluation of steganographic algorithms, but also might be a starting point for a new detection system of network steganography. The concept of a new detection system, called MoveSteg, is explained in detail.

“…This constraint means that practically only five or six bits in the TTL field can be used for covert transmission, with regular IP transmission still operational. Another interesting method, which can be applied in wireless networks, is the altering of the Timestamp field in Beacon frames broadcasted by IEEE 802.11 access points [ 29 ]. This method modifies the least significant bits of that field to embed covert data.…”

The proposed StegoFrameOrder (SFO) method enables the transmission of covert data in wireless computer networks exploiting non-deterministic algorithms of medium access (such as the distributed coordination function), especially in IEEE 802.11 networks. Such a covert channel enables the possibility of leaking crucial information outside secured network in a manner that is difficult to detect. The SFO method embeds hidden bits of information in the relative order of frames transmitted by wireless terminals operating on the same radio channel. The paper presents an idea of this covert channel, its implementation, and possible variants. The paper also discusses implementing the SFO method in a real environment and the experiments performed in the real-world scenario.

“…Covert channel uses the unused bandwidth [12] and do not add any overhead. If the authentication string sent by Access Point (AP) matches with that of the client then only client connects with AP else it disconnects [13]. It has been shown in fig.…”

Rogues are unwanted whether they are access points or clients as they steal critical data and bandwidth. To detect a rogue access point different approaches are used. These approaches are briefly classified as Client-side approach, Server-side and Hybrid approach. Every approach has its own advantages and disadvantages. Clients have limited resources and do not possess much control over network when compared with servers. Amongst all approaches Hybrid approach is efficient because it minimizes the inabilities of client side approach and adds server control for detection of Rogue Access Points (AP). This paper aims at surveying different methods of rogue Access Point detection.
