This topic provides a description of AppLocker and can help you decide if your organization can benefit from deploying AppLocker application control policies. AppLocker helps you control which apps and files users can run. These include executable files, scripts, Windows Installer files, dynamic-link libraries DLLspackaged apps, and packaged app installers.

AppLocker is unable to control processes running under the system account on any operating system. AppLocker helps reduce administrative overhead and helps reduce the organization's cost of managing computing resources by decreasing the number of Help Desk calls that result from users running unapproved apps.

AppLocker addresses the following app security scenarios:. AppLocker has the ability to enforce its policy in an audit-only mode where all app access activity is registered in event logs. These events can be collected for further analysis.

Windows PowerShell cmdlets also help you analyze this data programmatically. AppLocker has the ability to deny apps from running when you exclude them from the list of allowed apps. When AppLocker rules are enforced in the production environment, any apps that are not included in the allowed rules are blocked from running. AppLocker can help you create rules that preclude unlicensed software from running and restrict licensed software to authorized users.

AppLocker policies can be configured to allow only supported or approved apps to run on computers within a business group. This permits a more uniform app deployment. AppLocker includes a number of improvements in manageability as compared to its predecessor Software Restriction Policies. Importing and exporting policies, automatic generation of rules from multiple files, audit-only mode deployment, and Windows PowerShell cmdlets are a few of the improvements over Software Restriction Policies.

In many organizations, information is the most valuable asset, and ensuring that only approved users have access to that information is imperative.

However, when a user runs a process, that process has the same level of access to data that the user has. As a result, sensitive information could easily be deleted or transmitted out of the organization if a user knowingly or unknowingly runs malicious software.

AppLocker can help mitigate these types of security breaches by restricting the files that users or groups are allowed to run. Software publishers are beginning to create more apps that can be installed by non-administrative users. This could jeopardize an organization's written security policy and circumvent traditional app control solutions that rely on the inability of users to install apps.

By creating an allowed list of approved files and apps, AppLocker helps prevent such per-user apps from running. AppLocker is a defense-in-depth security feature and not a security boundary. Windows Defender Application Control should be used when the goal is to provide robust protection against a threat and there are expected to be no by-design limitations that would prevent the security feature from achieving this goal. AppLocker can help you protect the digital assets within your organization, reduce the threat of malicious software being introduced into your environment, and improve the management of application control and the maintenance of application control policies.

AppLocker is included with enterprise-level editions of Windows. You can author AppLocker rules for a single computer or for a group of computers.

I have installed a certain python package netCDF4which contains compiled code extension module. I am running Anaconda and python 3. When importing the module from console, I get the following error:. I suspect that some crucial DLL file is blocked by company-wide security policy, which is quite restrictive.

For instance, binary files are blocked by default unless in the "program files" folder.

But my python distribution and the netCDF4 package are already within this folder, so I'm at loss how to explain this. The dependencies listed by the depencency walker tool are either system libraries or contained in the "program files" folder.

I started python in admin mode, and used the tool Process Explorer to log which DLL files were loaded. I then started python in user mode, and used ctypes. WinDLL to load each of these libraries manually. I was then able to pinpoint the exact library hdf5. It turned out that hdf5. Although my problem was very specific, I hope that my solution can help others in related situations Very importantly, keep on drilling down through indirect dependencies until you find the missing DLLs.

The path condition identifies an application by its location in the file system of the computer or on the network. When creating a rule that uses a deny action, path conditions are less secure than publisher and file hash conditions for preventing access to a file because a user could easily copy the file to a different location than the location specified in the rule.

Because path rules specify locations within the file system, you should ensure that there are no subdirectories that are writable by non-administrators. The following table describes the advantages and disadvantages of the path condition.

It might be less secure if a rule that is configured to use a folder path contains subfolders that are writable by non-administrators. You must 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. You should always specify the full path to a file or folder when creating path rules so that the rule will be properly enforced. When combined with any string value, the rule is limited to the path of the file and all the files under that path. AppLocker uses path variables for well-known directories in Windows. Path variables are not environment variables. The AppLocker engine can only interpret AppLocker path variables.

The following table details these path variables.

The Application Identity service must be running or configuration changes cannot be processed. Contrary to popular belief the service is not required for rule enforcement — stopping it does not unblock restricted applications.

AppLocker can operate in auditing mode, enforcement mode or switched off completely. The mode of operation is configured for each file type individually.

It is therefore easily possible to audit scripts, enforce applications and leave installers and DLLs alone. Similar to a firewall, AppLocker works with rules that control whether to log, permit or deny an operation. Rules apply to users or groups, not computers. This makes it possible to differentiate between restricted standard users and unrestricted power users, for example. AppLocker rules are typically distributed by domain-based group policy. Configuring AppLocker through local group policy is possible, too.

Additionally, rules can be created from PowerShell. It is also possible to test from PowerShell whether specific files are allowed to run.

Rules Similar to a firewall, AppLocker works with rules that control whether to log, permit or deny an operation.The result is similar to a kiosk devicebut with multiple apps available. For example, you might set up a library computer so that users can search the catalog and browse the Internet, but can't run any other apps or change computer settings. For devices running Windows 10, versionwe recommend the multi-app kiosk method.

AppLocker rules specify which apps are allowed to run on the device. AppLocker rules are organized into collections based on file format.

If no AppLocker rules for a specific rule collection exist, all files with that file format are allowed to run. However, when an AppLocker rule for a specific rule collection is created, only the files explicitly allowed in a rule are permitted to run. For more information, see How AppLocker works.

This topic describes how to lock down apps on a local device. You can also use AppLocker to set rules for applications in a domain by using Group Policy. First, install the desired apps on the device for the target user account s. For UWP apps, you must log on as that user for the app to install.

For desktop apps, you can install an app for all users without logging on to the particular account. After you install the desired apps, set up AppLocker rules to only allow specific apps, and block everything else. Check Configured under Executable rulesand then click OK. Right-click Executable Rules and then click Automatically generate rules.

For a more secure experience, we recommend that you make the following configuration changes to the device:.
