Why are air-gapped networks used?

They are used to protect critical systems and data by making it extremely difficult for unauthorized users to gain access.

What is the main advantage of an air gap?

The main advantage is a significantly reduced attack surface, since the system is not connected to external networks.

Are there any drawbacks to air-gapped networks?

Yes, they can be harder to operate, update, and integrate with other systems, often requiring manual processes.

Where are air-gapped networks typically used?

They are commonly used in OT environments, industrial control systems, and other high-risk or high-security areas.

Air-gapped networks

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.
