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 trusted applications in a whitelist
- potentially trusted applications in an orangelist (also known as a graylist)
- everything else in a blacklist
Automated blacklists are problematic, as they will break common functionality.
An exception blacklist will block any software that is not covered by Whitelist or Orangelist policies. Exception Blacklisting should only be implemented after much analysis, end user education, and policy refinement.
[[What's the difference between an Automated Blacklist and an Exception Blacklist?]]
Exception policy. . .this approach is a good initial step when rolling out policies as often times you don’t know what applications are actually exceptions. A policy will be created to blacklist or deny any policies that don’t meet the whitelist or orangelist criteria. Prevent unnecessary helpdesk calls, create a custom message for the blacklist policy.
You can add applications to a blacklist using some of the following criteria:
- Application attributes
- File hash
- Location
- Untrusted applications
