This is useful so you can monitor what rules or settings are working, and determine if any settings are too "noisy" or impacting your day to day workflow. Reviewing the events is also handy when you are evaluating the features, as you can enable audit mode for the features or settings, and then review what would have happened if they were fully enabled. This topic lists all the events, their associated feature or setting, and describes how to create custom views to filter to specific events. You can also get detailed reporting into events and blocks as part of Windows Security, which you access if you have an E5 subscription and use [Microsoft Defender Advanced Threat Protection](../microsoft-defender-atp/microsoft-defender-advanced-threat-protection.md). ## Use custom views to review attack surface reduction capabilities You can create custom views in the Windows Event Viewer to only see events for specific capabilities and settings. The easiest way to do this is to import a custom view as an XML file. You can copy the XML directly from this page. You can also manually navigate to the event area that corresponds to the feature. ### Import an existing XML custom view 1. Create an empty .txt file and copy the XML for the custom view you want to use into the .txt file. Do this for each of the custom views you want to use. Rename the files as follows (ensure you change the type from .txt to .xml): - Controlled folder access events custom view: *cfa-events.xml* - Exploit protection events custom view: *ep-events.xml* - Attack surface reduction events custom view: *asr-events.xml* - Network/ protection events custom view: *np-events.xml* 1. Type **event viewer** in the Start menu and open **Event Viewer**. 3. Click **Action** > **Import Custom View...** ![Animation highlighting Import custom view on the left of the Even viewer window](images/events-import.gif) 4. Navigate to where you extracted XML file for the custom view you want and select it. 4. Click **Open**. 5. This will create a custom view that filters to only show the events related to that feature. ### Copy the XML directly 1. Type **event viewer** in the Start menu and open the Windows **Event Viewer**. 3. On the left panel, under **Actions**, click **Create Custom View...** ![Animation highlighting the create custom view option on the Event viewer window ](images/events-create.gif) 4. Go to the XML tab and click **Edit query manually**. You'll see a warning that you won't be able to edit the query using the **Filter** tab if you use the XML option. Click **Yes**. 5. Paste the XML code for the feature you want to filter events from into the XML section. 4. Click **OK**. Specify a name for your filter. 5. This will create a custom view that filters to only show the events related to that feature. ### XML for attack surface reduction rule events ```xml ``` ### XML for controlled folder access events ```xml ``` ### XML for exploit protection events ```xml ``` ### XML for network protection events ```xml ``` ## List of attack surface reduction events All attack surface reductiond events are located under **Applications and Services Logs > Microsoft > Windows** and then the folder or provider as listed in the following table. You can access these events in Windows Event viewer: 1. Open the **Start** menu and type **event viewer**, and then click on the **Event Viewer** result. 2. Expand **Applications and Services Logs > Microsoft > Windows** and then go to the folder listed under **Provider/source** in the table below. 3. Double-click on the sub item to see events. Scroll through the events to find the one you are looking. ![Animation showing using Event Viewer](images/event-viewer.gif) Feature | Provider/source | Event ID | Description :-|:-|:-:|:- Exploit protection | Security-Mitigations (Kernel Mode/User Mode) | 1 | ACG audit Exploit protection | Security-Mitigations (Kernel Mode/User Mode) | 2 | ACG enforce Exploit protection | Security-Mitigations (Kernel Mode/User Mode) | 3 | Do not allow child processes audit Exploit protection | Security-Mitigations (Kernel Mode/User Mode) | 4 | Do not allow child processes block Exploit protection | Security-Mitigations (Kernel Mode/User Mode) | 5 | Block low integrity images audit Exploit protection | Security-Mitigations (Kernel Mode/User Mode) | 6 | Block low integrity images block Exploit protection | Security-Mitigations (Kernel Mode/User Mode) | 7 | Block remote images audit Exploit protection | Security-Mitigations (Kernel Mode/User Mode) | 8 | Block remote images block Exploit protection | Security-Mitigations (Kernel Mode/User Mode) | 9 | Disable win32k system calls audit Exploit protection | Security-Mitigations (Kernel Mode/User Mode) | 10 | Disable win32k system calls block Exploit protection | Security-Mitigations (Kernel Mode/User Mode) | 11 | Code integrity guard audit Exploit protection | Security-Mitigations (Kernel Mode/User Mode) | 12 | Code integrity guard block Exploit protection | Security-Mitigations (Kernel Mode/User Mode) | 13 | EAF audit Exploit protection | Security-Mitigations (Kernel Mode/User Mode) | 14 | EAF enforce Exploit protection | Security-Mitigations (Kernel Mode/User Mode) | 15 | EAF+ audit Exploit protection | Security-Mitigations (Kernel Mode/User Mode) | 16 | EAF+ enforce Exploit protection | Security-Mitigations (Kernel Mode/User Mode) | 17 | IAF audit Exploit protection | Security-Mitigations (Kernel Mode/User Mode) | 18 | IAF enforce Exploit protection | Security-Mitigations (Kernel Mode/User Mode) | 19 | ROP StackPivot audit Exploit protection | Security-Mitigations (Kernel Mode/User Mode) | 20 | ROP StackPivot enforce Exploit protection | Security-Mitigations (Kernel Mode/User Mode) | 21 | ROP CallerCheck audit Exploit protection | Security-Mitigations (Kernel Mode/User Mode) | 22 | ROP CallerCheck enforce Exploit protection | Security-Mitigations (Kernel Mode/User Mode) | 23 | ROP SimExec audit Exploit protection | Security-Mitigations (Kernel Mode/User Mode) | 24 | ROP SimExec enforce Exploit protection | WER-Diagnostics | 5 | CFG Block Exploit protection | Win32K (Operational) | 260 | Untrusted Font Network protection | Windows Defender (Operational) | 5007 | Event when settings are changed Network protection | Windows Defender (Operational) | 1125 | Event when Network protection fires in Audit-mode Network protection | Windows Defender (Operational) | 1126 | Event when Network protection fires in Block-mode Controlled folder access | Windows Defender (Operational) | 5007 | Event when settings are changed Controlled folder access | Windows Defender (Operational) | 1124 | Audited Controlled folder access event Controlled folder access | Windows Defender (Operational) | 1123 | Blocked Controlled folder access event Controlled folder access | Windows Defender (Operational) | 1127 | Blocked Controlled folder access sector write block event Controlled folder access | Windows Defender (Operational) | 1128 | Audited Controlled folder access sector write block event Attack surface reduction | Windows Defender (Operational) | 5007 | Event when settings are changed Attack surface reduction | Windows Defender (Operational) | 1122 | Event when rule fires in Audit-mode Attack surface reduction | Windows Defender (Operational) | 1121 | Event when rule fires in Block-mode
