| <h2>Permissions:</h2> |
| <p> |
| Your Windows User must have permissions to read the given Event Log. This can be achieved through the following steps (Windows 2008 and newer): |
| <ol> |
| <li>Open a command prompt as your user. Enter the command: wmic useraccount get name,sid</li> |
| <li>Note the SID of the user or group you'd like to allow to read a given channel</li> |
| <li>Open a command prompt as Administrator. enter the command: wevtutil gl CHANNEL_NAME</li> |
| <li>Take the channelAccess Attribute starting with O:BAG, copy it into a text editor, and add (A;;0x1;;;YOUR_SID_FROM_BEFORE) to the end</li> |
| <li>Take that text and run the following command in your admin prompt (see below for example): wevtutil sl CHANNEL_NAME /ca:TEXT_FROM_PREVIOUS_STEP</li> |
| </ol> |
| |
| <p>The following command is the exact one I used to add read access to the Security log for my user. (You can see all the possible channels with: wevtutil el):</p> |
| <p>wevtutil sl Security /ca:O:BAG:SYD:(A;;0xf0005;;;SY)(A;;0x5;;;BA)(A;;0x1;;;S-1-5-32-573)(A;;0x1;;;S-1-5-21-3589080292-3448680409-2446571098-1001)</p> |

| <p>These steps were adapted from <a href="https://blogs.technet.microsoft.com/janelewis/2010/04/30/giving-non-administrators-permission-to-read-event-logs-windows-2003-and-windows-2008/">this guide.</a></p> |
