Description: The IP whitelist is a security practice that allows only specific IP addresses to access a resource while blocking all others. This approach is fundamental for protecting systems and applications from unauthorized access, as it limits exposure to external threats. In the context of various network and cloud services, IP whitelists are used to control incoming traffic and ensure that only trusted users or systems can interact with resources. This technique not only enhances security but can also optimize performance by reducing unwanted traffic. Whitelists can be configured flexibly, allowing for the inclusion of IP ranges or individual addresses, providing granular control over who can access services. Additionally, their implementation is relatively straightforward, making them a popular choice for many organizations looking to strengthen their security posture in the cloud.
