The AppLocker Microsoft Management Console (MMC) snap-in is organized into four areas called rule collections. The four rule collections are executable files, scripts, Windows Installer files, and DLL files.
These collections give the administrator an easy way to differentiate the rules for different types of applications.
Rule conditions are criteria that the AppLocker rule is based on. Primary conditions are required to create an AppLocker rule. The three primary rule conditions are publisher, path, and file hash.
Publisher - This condition identifies an application based on its digital signature and extended attributes.
The digital signature contains information about the company that created the application (the publisher).
The extended attributes, which are obtained from the binary resource, contain the name of the product that the application is part of and the version number of the application. The publisher may be a software development company, such as Microsoft, or the information technology department of your organization.
Path - This condition identifies an application by its location in the file system of the computer or on the network. AppLocker uses path variables for directories in Windows.
File hash - When the file hash condition is chosen, the system computes a cryptographic hash of the identified file.
