Definitions[]

Content filter[]

White lists are

lists of URLs or IP addresses that a filtering company has determined do not lead to any content its filter is designed to block, and, thus, should never be blocked. A very restrictive filter, like a "walled garden" filter, might block all URLs except those included on a white list.[1]

General[]

A whitelist is

[a] list of entities that are considered trustworthy and are granted access or privileges.[2]

Intelligence[]

White list is

[t]he identities and locations of individuals who have been identified as being of intelligence or counterintelligence interest and are expected to be able to provide information or assistance in existing or new intelligence areas of interest.[3]

Software filter[]

When used, whitelisting prevents all software from being executed on a computer except for those software packages that have been specifically allowed.
