Attacks on critical systems are on the rise, but how do you protect what can’t be patched? ‘Airgapping’ key systems by isolating them from the internet is often recommended, but it’s hard to achieve 100% effectively, according to Morey Haber, VP of technology at Beyond Trust. “Power generation, secure engineering drawings, and even trade secrets need to be imported and exported from these environments proving that they are not 100% air gapped but rather in a secure network zone with no direct internet access, inbound or outbound,” he explains.
