What are rule conditions?
Rule conditions are properties of files that AppLocker uses to enforce rules. Each AppLocker rule can use one primary rule condition. The following three rule conditions are available in AppLocker: Publisher rule conditions can only be used for files that are digitally signed by a software publisher. This condition type uses the digital certificate (publisher name and product name) and properties of the file (file name and file version). This type of rule can be created for an entire product suite, which allows the rule in most cases to still be applicable when the application is updated. Path rule conditions are based on the file or folder installation path of specific applications. File hash rule conditions are based on the unique file hash that Windows cryptographically computes for each file. This condition type is unique, so each time that a publisher updates a file, you must create a new rule.
