Air-gapping means physically isolating a secure computer from unsecured networks, such as the public Internet or an unsecured local area network. The concept of air-gapping represents just about the maximum protection one network can have from another,… Continue reading Meet NFCdrip – a New Security Concern for Air-Gapped Systems
Corporate networks and user PCs continue to be exploited—leaving your sensitive applications and data vulnerable. Network segmentation is a fundamental way to mitigate the risks associated with these vulnerabilities—but it only works if aut… Continue reading Securing Apps When User Devices Are Compromised
