In facility security, what does "cybersecurity" refer to?

Cybersecurity specifically refers to the protection of information systems and data from digital attacks and unauthorized access. This includes measures taken to safeguard classified information that is stored electronically, which is crucial for maintaining the integrity, confidentiality, and availability of sensitive data.

The focus on classified information emphasizes the importance of ensuring that such data is only accessed by authorized personnel and protected from threats like hacking, malware, and other cyber incidents. With the rise of digital information storage and communication, effective cybersecurity practices become vital in securing these systems against evolving cyber threats.

In contrast, the other options pertain to physical security and training aspects rather than the digital landscape. Physical security measures target the construction and protection of physical spaces, while training personnel focuses on educating staff on security procedures to prevent breaches. Lastly, controlling physical access addresses who can enter a facility, which is separate from the cybersecurity domain that handles electronic information and systems security.
