An air-gapped system is one that is physically isolated from all other networks, including the Internet. This physical separation ensures that no data can enter or leave the system electronically, providing maximum security for sensitive information. Enabling a host-based firewall can control incoming and outgoing traffic but does not prevent network connectivity. Using network segmentation with VLANs separates network traffic logically but still allows communication over the network infrastructure. Deploying an Intrusion Detection System (IDS) helps monitor and detect suspicious activities but does not prevent network access or isolate the server from external networks.
