Application whitelisting is the process of allowing applications or sets of applications to function within an organization.
This process is the opposite of the blacklisting of application which blocks a set of applications.
Application whitelisting is considered to be one of the safest cyber-security practices as this process only allows the desired/required applications to run through and blocks the rest of the applications.
We will be looking at some of the best practices in the application whitelisting through this blog. These practices will help you to implement application whitelisting process in your organizational environment.
List of Best Practices for Application Whitelisting

There are certain applications that companies choose to deploy on-premise instead of cloud due to privacy, security, or intellectual property requirements.
These on-premise applications are also vital to day-to-day business operations. Hence, as a cyber-security admin, you need to whitelist these sets of applications.
