Malware can prevent from running by adding the executable file to a whitelist, which will allow only authorized programs to run on the system. Similarly, websites can allow to open in browsers only if they are on a pre-approved list. This prevents accidental exposure to malicious content, phishing attacks, and other online threats.

Whitelisting can also be use to restrict user access to specific applications or data. For example, a company might want to allow employees to access only the applications they need for their work duties and nothing else. Or, a parent might want to whitelist only certain websites that are appropriate for their children to visit.

This can be done by manually adding the applications to a list, or by using an automated tool such as AppLocker.

Email whitelisting is a process that allows only specific email senders and recipients to send emails to a system. This can be done by adding the email addresses to a list, or by using an automated tool such as Spamhaus.
