IP Whitelisting
IP whitelisting is a security technique that restricts access to a network, system, or application by allowing only specific IP addresses or ranges, while blocking all others. It is commonly used to protect sensitive resources like servers, databases, and APIs from unauthorized access. This approach enhances security by creating a controlled access list based on trusted IP addresses.
Developers should learn IP whitelisting when building secure applications that require restricted access, such as internal tools, admin panels, or production environments. It is particularly useful for protecting APIs from abuse, securing database connections, and limiting access to development or staging servers. This technique helps prevent unauthorized intrusions and reduces the attack surface by allowing only known, trusted sources.
