Why are "tailgating" and "piggybacking" considered security concerns?

“Tailgating” and “piggybacking” are recognized security concerns primarily because they involve unauthorized individuals gaining access to secure areas. Tailgating typically occurs when someone follows an authorized person into a restricted area without the necessary credentials, often taking advantage of the authorized individual's access rights. Piggybacking, while similar, refers to the scenario where an unauthorized individual accompanies an authorized person into a secured area, sometimes with the authorized individual’s consent or knowledge.

The significance of this issue lies in the potential risks to physical security and data integrity. When unauthorized persons are allowed entry, they might observe sensitive operations, steal information, or even conduct malicious activities. Ensuring that only those with the proper authorization can access secure locations is crucial for safeguarding against theft, espionage, or unintentional breaches of protocol. Hence, prevention measures against these tactics are integral to maintaining security in vulnerable environments.
