File Integrity Manager

[Bijesh Maskey]

I have OSSEC Server setup in CentOS and working perfectly fine.. now i want to tune the it. As we already have SIEM server. I would like to disable all the logs except the FIM. I have gone through various documents as FIM only alerts up to 3 changes only via email now i would like to alter only the FIM and nothing else. can anyone guide me or provide a link for me to do require setup. also i  couldnt find where shall i configure ossec to notify file chages even though it is greater than 3 changes via email. 

thanks

regards

There's an auto ignore option you can set to no to enable email past the third change.
