What is whitelisted meaning?

Whitelisting is a practice of allowing certain users, IP addresses, or domains to access restricted systems, networks, or applications. In other words, it is a security measure that permits only approved sources to access a particular resource.

Whitelisting is often used in contrast to blacklisting, which blocks access to unauthorized users, IP addresses, or domains. While blacklists are more restrictive and reactive, whitelisting is more proactive and ensures a higher level of security.

Examples of whitelisting include allowing a specific set of users to access sensitive data, or allowing only certain IP addresses to connect to a company's servers. In general, whitelisting is considered a best practice in network security because it minimizes the risk of unauthorized access and improves overall system performance.
