Air-Gapped Network

A security measure that isolates a network from unsecured external connections to prevent cyber threats.

Understanding Air-Gapped Networks


These networks are used in high-security environments where data confidentiality and integrity are critical. They prevent cyber threats by completely disconnecting sensitive systems from external access.

Key Security Features


Physical Isolation

  • No direct or wireless connection to unsecured networks.

  • Used in military, government, and critical infrastructure sectors.

Manual Data Transfers

  • Data transfer requires physical media (USB, DVDs).

  • Strict protocols to prevent malware infection through removable devices.

Restricted Access Controls

  • Only authorized personnel can access the network.

  • Requires stringent authentication mechanisms.

Best Practices


  • Use secure data transfer mechanisms (encrypted USB drives).

  • Regularly inspect and monitor access points for unauthorized connections.

  • Implement physical security measures to prevent unauthorized access.
