What is IP whitelisting?
IP whitelisting is a security mechanism that controls access to an app, network, or system based on the IP (internet protocol) address of the incoming connections.
Also known as IP filtering, IP whitelisting works because every device or network on the internet has a unique identifier known as an IP address.
Monitoring IP addresses is a core aspect of security. For example, if you discover malicious traffic from a source, you can blacklist (or block) the problematic IP address. Whitelisting allows only specified IP addresses to access a protected system while blocking all others.
Any connection that originates from an IP not on the whitelist is denied access automatically. This reduces the attack surface for malicious parties, helping to reduce the risk of unauthorized access, data breaches, and malicious activities.
IP whitelisting effectively controls and restricts access to sensitive resources, apps, or systems. It offers an additional security layer that should be implemented alongside other security measures, such as authentication, encryption, and monitoring. IP whitelisting is commonly applied at the app or server level to control access to apps or APIs.
