In video a large amount of data can be hidden which is becoming increasingly a concern of interest . It is very hard to detect the inside attacker in the organization network who can extract the sensitive information from organization and transfer that information in hidden format through the video steganography. To ensure privacy and security the authors have proposed an effective steganalysis method to detect hidden data in video by using the SDN framework policy. With the help of the SDN framework administrator of private network can look at the whole network and control the network by programming. The main objective of this paper is to prevent the illegal data transmission from the compromised private network by the malicious users.
