Use the Append Text to File active response in SEM

Use the Append Text To File active response to append static or dynamic text to a flat text file in your network. This action helps you keep a running list of deployed SEM agents or track certain types of activity across several users and computers. You can automate this response with a SEM rule or execute it manually from the Respond menu on the SEM Console.


To use this active response, ensure that the file you want to append already exists. Follow these guidelines when creating the file:

  • Use a .txt file, or a similar flat-text file format.

  • Avoid using spaces in the file path or name.

  • Note the complete file path and name, because you will need it to configure the active response.

Configure the Append Text to File active response and Windows active response connectors on each SEM Agent on which you want to be able to use this active response.
