What is air-gapped networks?
An air-gapped network is a system or network that is physically isolated from other networks, especially the internet.
This means the system has no direct or indirect connection to external networks. This level of isolation makes it extremely difficult for attackers to gain access, even in advanced threat scenarios.
Air-gapped networks are commonly used to protect critical systems, such as industrial control systems or sensitive data environments, where the impact of a breach can be severe.
A simple way to understand an air-gapped network is to think of it as a system completely disconnected from the outside world, like a computer with no network connection placed in a physically secured room.
Sicra and air-gapped networks
Air-gapped networks are relevant in security architecture, risk assessment, and the protection of critical infrastructure.
At Sicra, the concept is used to assess how organizations can reduce their attack surface and protect highly sensitive systems, particularly in OT environments and other high-risk areas.
