Which of the following is generally practiced by the police or any other recognized governmental authority?

Spoofing is a malicious technique where an attacker impersonates another identity, IP address, or source to deceive victims or systems, not a law enforcement practice.

SMB signing is a security feature that digitally signs Server Message Block packets to verify authenticity and prevent man-in-the-middle tampering, not a governmental surveillance method.

Wiretapping refers to the covert monitoring or interception of telephone, internet, or other electronic communications by law enforcement under legal authorization such as court orders or warrants. It is a technique legally reserved for recognized governmental bodies conducting authorized investigations. Unlike spoofing or phishing, wiretapping is a sanctioned investigative practice, not a malicious attack technique.

Phishing is a social engineering attack used by malicious actors to trick users into revealing credentials or sensitive information, not a practice of governmental authorities.
