What Are Software Whitelisting and Blacklisting?

In the world of computer security, whitelisting and blacklisting are two common methods used to control access to resources. These methods are used to prevent unauthorized access to a system and to ensure that only approved applications and services are allowed to run. Blacklisting refers to the practice of blocking or denying access to a list of specific websites, applications, or IP addresses, while whitelisting is the opposite, allowing access only to a pre-approved list of sites, applications, or IP addresses. These two methods are used to secure networks and protect against potential cyber attacks.

In this article, we will dive deeper into the concepts of blacklisting and whitelisting, their advantages and disadvantages, and how they are used in cybersecurity.
