Vibration adhesion is the tendency of two surfaces to stick more, or less, when repeated motion is applied. In practice, vibration changes the contact point: friction, surface texture, pressure, and resonance can all alter whether an object stays attached or slips. This is not the same as glue or suction; it is a motion-driven effect at the interface between materials.
In cyber security, vibration adhesion matters wherever hardware is physically stressed: mounted sensors, rack equipment, connectors, locks, and tamper seals. Attackers may use shaking or vibration to loosen parts, trigger intermittent faults, or exploit unstable contacts in poorly secured devices. Defenders test for it by validating equipment under vibration, shock, and environmental stress, and by using locking fasteners, strain relief, tamper detection, and redundant contacts so behavior remains stable when conditions change.
