What Is MFA for Air-Gapped Networks? Closing the Last Security Gap in Isolated Systems
Air-gapped networks are supposed to be untouchable. No internet connection, no remote pathway, no way in for an attacker sitting halfway across the world. But ask any security team that has actually run one of these environments, and you'll hear a different story. Air gaps stop remote attacks cold. But they do almost nothing to stop a stolen password, a careless USB stick, or an insider with too much trust and too little oversight. That's the gap, and Multi-Factor Authentication (MFA) is here to fill it.
