What is Application Blacklisting?
Application Blacklisting prevents unwanted applications from running in your environment.
Arellia's Application Control Solution allows you to manage applications flexibly in a large, distributed client environment by putting:
- known Known trusted applications in a whitelist
- potentially Potentially trusted applications in an orangelist (also known as a graylist)
- everything Everything else in a blacklist
