![]() For example, you can create a rule to “Allow users in the Finance security group to run the finance line-of-business applications.” This blocks everyone who is not in the Finance security group from running finance applications (including administrators) but still provides access for those that have a business need to run the applications. This allows an administrator to support compliance requirements by validating and enforcing which users can run specific applications. Using an exception, you could create a rule to “Allow everything in the C:\Windows or C:\Program Files directories to be run, except the built-in games.”ĪppLocker rules can be associated with a specific user or group. “Deny” rules take precedence over “allow” rules.Įach rule can also have a list of exceptions to exclude files from the rule.

MSP) for both install and uninstallĪppLocker provides a simple GUI rule-based mechanism, which is very similar to network firewall rules, for determining which applications or scripts are allowed to be run by specific users and groups, using conditional ACEs and AppID attributes. ![]() AppLocker auditing mode can be used to monitor which applications are being used by one, or more, users on a system.ĪppLocker allows an administrator to restrict the following types of files from being run: Another feature that makes AppLocker superior to SRP is AppLocker’s auditing mode, which allows an administrator to create an AppLocker policy and examine the results (stored in the system event log) to determine whether the policy will perform as expected-without actually performing the restrictions. If both AppLocker and SRP rules are in the same Group Policy object (GPO), only the AppLocker rules will be applied. (All users were affected by SRP rules.) AppLocker is a replacement for SRP, and yet coexists alongside SRP, with AppLocker’s rules being stored separately from SRP’s rules. Windows XP introduced Software Restriction Policies (SRP), which was the first step toward this capability, but SRP suffered from being difficult to manage, and it couldn’t be applied to specific users or groups. That’s how simple it is to use AppLocker to block any file from getting executed.New to Windows 7 and Windows Server 2008/R2 (Enterprise and Ultimate editions) is a feature known as AppLocker, which allows an administrator to lockdown a system to prevent unauthorized programs from being run. The rule to block Notepad gets created and users are not allowed to execute Notepad on the system.

The following are the steps to create a rule in AppLocker. The following are the types of files AppLocker is capable of blocking. AppLocker rulesĪppLocker is capable of blocking different file types. For a group of computers, it can be done using the Group Policy Management Console. ![]() For standalone systems, rules can be enforced using the Local Security Policy editor (secpol.msc). AppLocker is inbuilt into Windows OS enterprise-level edition and needs no additional installation onto the system. ![]()
