increasing the security and safety of the network. The VPN can be accessed by the trusted members of the organization, hence no unknown traffic can enter the realms of VPN. The VPN requires prior authentication to access the network. • Strong & Unique Passwords The passwords created to access the network should be strong and kept confidential to save the network from breach or been accessed by the hacker. The passwords should be changed periodically. • Regular Software Updation of UC The…

Steganography, or data hiding is the technique of embedding a message (pay¬load) in a medium (carrier), without causing suspicion about the existence of hidden data in the medium. The perturbations to the medium are carried out in such a manner that there is no perceivable noise component introduced. One way to illustrate the concept of steganography would be to analyze the Sim¬mons’ Prisoners’ problem.
