What is the primary difference between impersonation and masquerading?
I know that masquerading is to impersonate a false identity and replaying is the same wherein an unauthorised person uses the credentials of the authorised one to have the privileges.Then what is the difference between the two terms?
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.
