Which of the following could indicate a breach of security in a correctional facility?

An unauthorized person in a restricted area is a significant indicator of a potential breach of security in a correctional facility. Such an incident raises alarms as it can suggest that security protocols have been compromised, which may lead to serious consequences such as escape attempts, smuggling of contraband, or potential harm to staff and inmates. Restricted areas are typically secure zones that are not accessible to anyone without proper clearance, and the presence of unauthorized individuals in these areas directly threatens the safety and security of the facility. Identifying and addressing such breaches swiftly is critical to maintaining order and ensuring the safety of everyone within the correctional environment.
