What is the purpose of whitelisting?

Website Whitelist is a browser extension that allows users to identify sites to be whitelisted, and prevents any request to sites not included on that list . The extension also blocks external tracking and advertising websites.

A whitelist (or, less commonly, a passlist or allowlist) is a mechanism which explicitly allows some identified entities to access a particular privilege, service, mobility, or recognition i.e. it is a list of things allowed when everything is denied by default.

The goal of whitelisting is to protect computers and networks from potentially harmful applications . In general, a whitelist is an index of approved entities. In information security (infosec), whitelisting works best in centrally managed environments, where systems are subject to a consistent workload.

Commonly Used Alternative Terms for Whitelist: Allowlist and Acceptlist are the terms used in firewalls. We also have seen “Safelist” as an alternative for the term whiteliste. Another one we just heard recently is “welcome-list”. By the logic of not changing abbreviations, this term makes a lot of sense.
