Masquerading is synonymous with __________.

Masquerading is the act of impersonating another legitimate user, device, or entity to bypass authentication or gain unauthorized privileges. This deception of identity is precisely what spoofing entails, whether it's IP spoofing, email spoofing, or identity spoofing, making the terms synonymous in this context.

DNS poisoning involves corrupting DNS cache data to redirect traffic, which is a specific attack, not a general synonym for masquerading.

ARP poisoning specifically manipulates the Address Resolution Protocol cache to redirect traffic, which is a particular type of network attack distinct from the general concept of masquerading.

Password cracking is the process of recovering passwords from stored data, which is a method to gain credentials, not the act of impersonating itself.
