Application Whitelisting
What is Application Whitelisting and How Does it Work?
Application whitelisting is a security measure that allows only approved applications to run on a computer or network. It is a form of defense-in-depth security that helps protect against malicious software, such as viruses, worms, and Trojans.
Application whitelisting works by creating a list of approved applications that are allowed to run on the computer or network. This list is known as a whitelist. Any application that is not on the whitelist is blocked from running. This helps to ensure that only trusted applications are allowed to run, reducing the risk of malicious software being installed or executed.
Application whitelisting can be implemented in a variety of ways. It can be done manually, by creating a list of approved applications and manually adding or removing applications from the list. It can also be done automatically, using software that monitors the system for changes and automatically adds or removes applications from the whitelist.
Application whitelisting is an effective way to protect against malicious software, as it prevents unauthorized applications from running. It is important to keep the whitelist up to date, as new applications are released and old applications are updated. This helps to ensure that only trusted applications are allowed to run on the system.
