I am new to OSSEC, but I do not see how to tell syscheck to only report when a log file is modified as opposed to added to. In other words, I am looking for a way to detect tampering with log files.

Could you provide more details?

Hello,

How can I configure ossec to alert me if somebody tampers with a log file?

In other words, I do not want to get alerts anytime something is added
to the log, but I want to get alerts if existing contents in the log
file is modified or deleted.

Thanks,
Lars
