Most machines aren't exploited due to missing patches (although this is the second biggest cause), unpatched zero days (almost never a factor), drive-by downloads, or misconfigurations.

The disadvantage is that each time the file is updated (such as a security update or upgrade) the file’s hash will change, thus making it immune to the current AppLocker policy, requiring a new rule to be created.When the infrastructure can support it, consider using Managed and Virtual Service Accounts functionality to manage service account password security.ĪppLocker application controlThe leading cause of malware infections may surprise you.

The advantage is that, because each file has a unique hash, a file hash rule condition applies to only one file.

Allows applications, which may not be signed by their publishers, to be managed under AppLocker.

For files that are not digitally signed, file hash rules are more secure than path rules.

Therefore, each time a publisher updates a file, you must create a new rule.

When the file hash condition is chosen, the system computes a unique cryptographic hash of the identified file that is based on the SHA256 algorithm that Windows uses.

You should always specify the full path to a file or folder when creating path rules so that the rule will be properly enforced. AppLocker does not enforce rules that specify paths with short names.AppLocker uses its own path variables for directories in Windows.The Path condition identifies an application by its location in the file system of the computer or on the network.You can make the rule more generic by moving the slider down or by using a wildcard character (*) in the product, file name, or version number fields. When you select a reference file for a publisher condition, the wizard creates a rule that specifies the publisher, product, file name, and version number.Publisher conditions can be created to allow applications to continue to function even if the location of the application changes or if the application is updated.

The publisher may be a software development company, such as Microsoft, or the information technology department of your organization. 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 digital signature contains information about the company that created the application (the publisher).

This condition identifies an application based on its digital signature and extended attributes.

Primary conditions are required to create an AppLocker rule. Rule conditions are criteria that the AppLocker rule is based on. Packaged apps and packaged app installers. The following table lists the file formats included in each rule collection.

The four rule collections are executable files, scripts, Windows Installer files and Packaged app. The AppLocker GPO setting can be found under Computer Configuration – Policies – Windows Settings – Security Settings – Application Control Policies – AppLockerĪppLocker is organized into four areas called rule collections. AppLocker is configured via GPO by creating various rules to either allow or deny applications.
