Air Gap Definition
An Air Gap, in the context of blockchain technology and cryptocurrency, refers to a security measure which involves keeping a computer, hardware wallet, or entire system completely isolated from the internet.
Air Gap Key Points
- An Air Gap is a security measure that isolates a system from the online world.
- This method is often used to secure cryptocurrency wallets.
- The objective of using Air Gap is to prevent unauthorized access and shield against the various computer vulnerabilities that can be exploited via the internet.
What is an Air Gap?
The Air Gap method is a security concept that defines physical or conceptual disconnect between a secure network and a potentially insecure network. When a device is “air-gapped,” it means that it is not connected to any other device or network that could compromise its data.
Why an Air Gap?
Cryptocurrency users often use Air Gaps as a security measure to ensure their wallets are safe from cyber threats. Cryptocurrencies like Bitcoin are typically stored in digital wallets, which are vulnerable to online threats if not adequately protected. By keeping these wallets isolated from the internet, users can avoid potential security breaches that could result in the loss of their assets.
Who uses Air Gap?
The use of Air Gap is not restricted to individual users only; companies or organizations handling sensitive data often use this method to secure their systems. These could be finance or healthcare companies that maintain their customers’ confidential information and therefore, cannot afford to risk unauthorized access or data breach.
When to use Air Gap?
If the information involved is of high value or extreme sensitivity, it may be worth employing an Air Gap. Typically, an Air Gap is employed when the risk of remote cyber-attacks via the internet is so significant that other risk control methods deliver insufficient protection.
Where is Air Gap applied?
Air Gap method is mainly applied in places where there is an increase in cybersecurity risks. These may include cryptocurrency storage, data centers, organizations dealing with confidential data or classified information, or even personal computers holding sensitive data.
How does an Air Gap work?
An Air Gap works by ensuring that the system or hardware is completely isolated from unsecured networks, mostly the internet. This disconnect guarantees that access to the data within the isolated system is strictly controlled and specifically authorized, making it very difficult for unauthorized entities to get in. However, remember that while Air Gap significantly improves security, it does not make a system entirely invincible to breaches as physical access challenges can still persist.
