# Create a simplified version of the log name for use elsewhere in the script # and then upload them to SQL Server efficiently # or all events if this is the first run of the script # Check event log for events written since this script was last run The script takes two parameters, the event log name to collect from, and the SQL server to send the events to.This means you can run it as often as you like an not get duplicate events in your SQL table. The script writes a registry marker when it runs, and on subsequent runs only uploads events that have occurred since its last run.I’ve configured the scheduled task via a Group Policy Preference. The collection script is launched via a scheduled task, runs as the Network Service account, does not show on the user’s desktop whilst running, and only requires the Domain Computers group to have access to the SQL database.The event collection script is written in PowerShell, you should probably have at least version 3 of this on your PCs, and.The PCs push the events to the SQL server using an SQL bulk copy, which is pretty efficient.Maybe use SQL Server 2014 Express – which is free. You need an SQL server to store the events that you’re going to collect from the PCs.This is going to be a big post with multiple sections, sorry about that, but it is pretty straightforward. This is also not restricted to the AppLocker event log, you can collect events from any Windows Event Log. You could of course modify the script and the SQL table to collect whatever fields you want. I think my version is better, because it allows you to query events in SQL, which is easier for me than trying to extract sensible information directly out of an event log – especially if the info you’re after is in the Messages field. After a few days of trying to get it to work on them, I gave up and wrote my own version in PowerShell. Sadly, it failed on the other 7498 Windows 7 PCs. I followed some instructions, and it worked fine on my Windows 8.1 PC, and also on a colleague’s Windows 10 PC. “Aha”, I thought, “this will be a great time to try out using the built in Windows Event Forwarding“. Now you need to collate it centrally and process it. You now have your PCs collecting all this useful info in their event logs. This makes it write messages into its event log telling what has been allowed to run, and what would be blocked from running were it in enforce mode rather than audit mode. Anyway, a sensible first step is to identify which paths things are running from, which is pretty easy – you just turn AppLocker on in Audit mode. That’s how simple it is to use AppLocker to block any file from getting executed.I’m currently in the process of planning for an AppLocker rollout to all my PCs (about 7,500 of them) due to an increasing amount of malware. The rule to block Notepad++ gets created and users are not allowed to execute Notepad++ on the system. Notepad++ Files not allowed to execute get populated, as shown.Ĭlick Next, give the name for the rule and click Create, as shown. We will deny Notepad++ from being executed, as shown.Ĭlick OK. Select Browse Folders and navigate to the path for the executable/file you want to deny execution. By default, rules applies to everyone, you can select User or Group as per the need: Select Deny for denying certain files from getting executed. Default Rules get created, as shown below.Ĭreate New Rule by right-clicking Executable Rules, as shown.Ĭlick Next. Under Application Control Policies, right-click on Executable Rules under AppLocker as shown.Ĭlick on Default Rules. Type local security policy and click “Run as Administrator”. 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.
