A wiretap is a method of intercepting and monitoring telephone or electronic communications, often used in law enforcement investigations. Wiretapping involves secretly listening to or recording conversations without the knowledge of the communicating parties. In most jurisdictions, wiretaps require a court order or legal authorization due to privacy concerns and legal restrictions. Cybersecurity professionals must be aware of wiretapping techniques, both to protect sensitive communications and to comply with legal standards. Unauthorized wiretapping is illegal and considered a serious invasion of privacy. Modern wiretaps may target not only traditional phone lines but also internet-based communications and data transmissions.
