Damian is the chief security officer of Enigma Electronics.

The measures Damian is implementing are part of the Physical layer of network defense-in-depth strategy. This layer involves securing the physical infrastructure of the organization, which includes controlling physical access to the building through mechanisms like two-factor authenticated locks and monitoring the environment with video surveillance. Additionally, implementing fire suppression systems is a part of safeguarding the physical premises against environmental hazards. These measures are essential to prevent unauthorized physical access and to protect against physical threats that could harm the network’s infrastructure. References: The Certified Network Defender (CND) program by EC-Council covers a defense-in-depth security strategy that includes the Physical layer as one of its core components12.
