Electromagnetic Radiation Isolation
Security researchers have been able to access sensitive data wirelessly from a malware-infected system, thus overcoming network isolation.
FM signals have been sent to a mobile phone within 7 meters with an effective bandwidth of 13 to 60 bytes per second. Although the attack complexity is high, it can still render network isolation or a vault useless.
Follow these recommendations to mitigate malicious wireless data access:
- Shield the vault from any electromagnetic radiation so that data cannot be accessed.
- Do not allow mobile phones, which can act as transceivers, inside the physical vault.
NOTE:If necessary, only allow approved mobile phones in the physical vault.
- Ensure that all other systems are physically isolated from systems in the production network by at least 7 meters.
