You asked - What is the primary difference between impersonation and masquerading

I can answer this as - A masquerade attack is an attack that uses a fake identity, such as a network identity, to gain unauthorised access to personal computer information through legitimate access identification. If an authorization process is not fully protected, it can become extremely vulnerable to a masquerade attack. Masquerade attacks can be perpetrated using stolen passwords and logins, by locating gaps in programs, or by finding a way around the authentication process, Replay attack is a network attack in which a malicious node may repeat the data or delay the data. This can be done by the originator who intercept the data and re-transmit it. Suppose node S wants to send some data to R. For this S has to prove his identity to R. This way S sends his password to R for identification. At that time, an attacker can intercept the password of S and present itself as S, when asked for the proof of identity. A sends S password read from the last session, which R accepts.
