Within a secure data center, engineers have enclosed an entire row of server racks inside a conductive mesh that blocks both incoming and outgoing electromagnetic fields. What is the primary security purpose of deploying this enclosure?
Physically deter intruders by acting as a hardened barrier that delays forced entry
Prevent electromagnetic eavesdropping and data leakage by blocking emissions
Provide redundant environmental controls such as precise humidity and temperature regulation
Detect unauthorized access attempts by monitoring ambient radio-frequency signals
The conductive enclosure is a Faraday cage. By blocking electromagnetic emissions, it prevents sensitive signals from being intercepted (TEMPEST/eavesdropping) and shields the equipment from external electromagnetic interference. This makes it a preventive physical control aimed at protecting the confidentiality and integrity of information-not a mechanism for detecting intrusions, regulating environmental conditions, or physically deterring forced entry.
