Many businesses implement both visible and invisible physical security controls to protect their assets. Alison works as a security analyst for a technology company that has an in-house security team to handle physical breaches on company property. However, when an employee's personal vehicle was broken into in the company parking lot, Alison explains that the security team only monitors company possessions, not personal items.

Physical security controls may be needed for both company and personal property depending on the environment and assessed risks.
