It means that you have some application which is trying to change csa files. Due to that you are hitting the agent self-protection rule and this alarm is being logged. Do you know which application is it? Do you have any other side effects from this alarm? If not and if its annoying for you, you can try to disable the alarm to be logged. In the csamc if you go to:
Configuration/Policies/Required Windows System Module and select Rule Agent Service Control at the bottom you
have the option to select for which applications you don't want alarm to be logged. The services.exe is the Windows Service Control Manager application.
