As a child you would wait. And watch from far away. But you always knew that you'd be the one that work while they all play. In youth you'd lay awake at night and scheme. Of all the things that you would change, but it was just a dream! Here we are.
A whitelist is a list or register of entities that provide a particular privilege, service, mobility, access or recognition. Entities on the list will be accepted, approved and/or recognized. Whitelisting is the reverse of blacklisting, the practice of identifying entities that are denied, unrecognised, or ostracised.
When a whitelist is used, all entities are denied access, except those included in the whitelist. The opposite of a whitelist is a blacklist, which allows access from all items, except those included the list. The following are examples of different whitelist applications: 1  A network administrator may configure a firewall with a whitelist that only allows specific IP addresses to access the network. 2  A protected directory within a website may use a whitelist to limit access to certain IP addresses.
