What is an example of a physical network attack?

A physical network attack involves direct interference with the physical components of a network, rather than relying on software-based methods or social engineering techniques. Cable tapping is a prime example of this, where an unauthorized person physically connects to a network cable to capture data as it flows over the wire. This type of attack is particularly concerning because it can often go unnoticed, allowing attackers to collect sensitive information without raising alarms.

In contrast, phishing involves tricking individuals into revealing personal information through deceptive emails or websites, making it a social engineering tactic rather than a physical one. A DDoS attack disrupts service by overwhelming a network with traffic but does so through software manipulation and does not require physical access to network infrastructure. Similarly, malware installation involves the use of malicious software to compromise systems, which again is executed digitally rather than physically. Thus, cable tapping accurately represents the nature of a physical network attack.
