Whitelisting takes more of a trust-centric approach and is considered to be more secure. However, simply blocking everything that is distrusted, even though simple and efficient, might not necessarily be the best approach. Around 230,000 samples of malware are produced everyday, making it impossible for an admin to keep a comprehensive and updated and list of malicious applications. And considering that 30 percent of malware tends to target zero-day vulnerabilities, there’s potential a security breach could happen before the affected applications are included in the blacklist.
Non-employees who try to gain entry, for example, interview candidates, will fall into the greylist, as they don’t form a part of the whitelist or the blacklist. The security guard either allows or denies their entry request based on its authenticity.
Inability to access essential applications would put various critical tasks on halt. Furthermore, determining which applications should be allowed to execute is an intensive process in itself. Just as the name suggests, whitelisting is the opposite of blacklisting, where a list of trusted entities such as applications and websites are created and exclusively allowed to function in the network.
Some organizations may station a security guard at their entrance to ensure that only employees with a valid ID are allowed access. This is the basic concept behind whitelisting; all entities requesting access will be validated against an already approved list and will be allowed only if they are present in that list.
