The four common types of physical lock-down systems for protecting hardware, especially in IT environments, include:
Cages: Enclosures for servers or critical equipment.
Plates: Lock-down plates secured to desks or floors.
Cables: Security cables to tether devices.
Alarms: Motion or tamper-detection systems.
These measures are used to deter theft and unauthorized physical access.
