In cybersecurity, a cable refers to a physical medium used to connect devices within a network, enabling the transmission of data, power, or signals. Common types include Ethernet cables (such as Cat5e or Cat6), fiber optic cables, and coaxial cables. The security of cables is crucial, as physical access can allow attackers to intercept or disrupt data transmission. Proper cable management, physical security measures, and the use of encrypted communication protocols help mitigate risks associated with cable-based attacks, such as wiretapping or signal interference. Cables are fundamental components in both local area networks (LANs) and wide area networks (WANs), serving as the backbone for secure and reliable data exchange.
