The protection of digital data is essential in the domain of occupational safety records. Violation of the security of digital data can lead to the disclosure of sensitive data and material losses, which can affect the health and life of workers, large material damages, as well as terrorist attacks. One of the aspects of digital data security is physical security, that is, a set of measures that prevent unauthorized physical access to data and resources. Threats to the physical security of digital data come from natural disasters such as floods and earthquakes and human vulnerabilities such as disobedience, sabotage or theft. Also, there are threats that are the result of unforeseen circumstances such as fire caused or some kind of malfunctions in various systems. Adequate protection measures, security of the environment and premises of the facilities, reception, and implementation of access control are introduced as a prevention to reduce damage after the appearance of the above-mentioned threats. Also, it is necessary to implement the protection of equipment and devices through available technologies. Various systems have been developed to establish and improve the physical security of digital data. Some of them are alarm systems and systems for monitoring, access control or locking of valuable devices.
