The tool is called AaronLocker and can be downloaded here: This tool will also add the domain values for SYSVOL and NETLOGON, block executables used for AppLocker bypasses as well as deny access to specific paths used for AppLocker bypasses. Microsoft has developed a tool for automatically creating a default set of rules for AppLocker. AppLocker is mostly aimed towards low-privileged users, whereas Windows Defender Application Control is mostly aimed towards the Operating System itself. Using Windows own application allowlisting solutions, we can choose from AppLocker and Windows Defender Application Control (formerly known as Device Guard or Configurable Code Integrity).ĪppLocker is the easiest to configure, design and deploy however, it’s possible for local administrators to bypass and disable this application whitelisting. Allowing only a specific set of applications to run on endpoints, besides some of Windows own binaries, can reduce the possibility of attackers executing arbitrary code on the endpoints. In addition to other measures, you need to control the access to sensitive data through app usage.Implementing application allowlisting should be one of the first priorities when securing a Windows Endpoint.Some computers in your organization are shared by people who have different software usage needs.A single user or small group of users needs to use a specific app that is denied for all others.Specific software tools aren't allowed within the organization, or only specific users have access to those tools.A new app or a new version of an app is deployed, and you need to allow certain groups to use it.The license to an app has been revoked or is expired in your organization, so you need to prevent it from being used by everyone.The potential that unwanted software can be introduced in your environment is high, so you need to reduce this threat.Your organization needs to restrict the use of Universal Windows apps to just those apps your organization approves of or develops.An app is no longer supported by your organization, so you need to prevent it from being used by everyone. Your organization's security policy dictates the use of only licensed software, so you need to determine which apps aren't licensed or prevent unauthorized users from running licensed software.The security policy for application usage has changed, and you need to evaluate where and when those deployed apps are being accessed.Your organization implements a policy to standardize the applications used within each business group, so you need to determine the expected usage compared to the actual usage.The following are examples of scenarios in which AppLocker can be used: You can also design application control policies for situations in which users share computers. As you manage ongoing change in your support of a business group's apps, you can modify policies and use the AppLocker cmdlets to test the policies for the expected results. This configuration permits a more uniform app deployment.ĪppLocker policies can be modified and deployed through your existing Group Policy infrastructure and can work in conjunction with policies created by using Software Restriction Policies. If an app isn't identified by its publisher, installation path, or file hash, the attempt to run the application fails.ĪppLocker can provide an inventory of software usage within your organization, so you can identify the software that corresponds to your software licensing agreements and restrict application usage based on licensing agreements.ĪppLocker policies can be configured to allow only supported or approved apps to run on computers within a business group. Windows PowerShell cmdlets are also available to help you understand app usage and access.ĪppLocker has the ability to deny apps from running simply by excluding them from the list of allowed apps per business group or user. Application control scenarios addressed by AppLocker can be categorized as follows:ĪppLocker has the ability to enforce its policy in an audit-only mode where all app access activity is collected in event logs for further analysis. This topic for the IT professional lists the various application control scenarios in which AppLocker policies can be effectively implemented.ĪppLocker can help you improve the management of application control and the maintenance of application control policies.
