I've added the following to the end of my httpd.conf, but I am not sure if it's in the right place. Is this the right place?

Also, it's not writing to the logs/mod_security2.log file (as copied from the mod_security download from here), but is writing issues to the error.log, modsec_audit.log, and the modsec_debug.log. I've placed the core mod_security rules into the conf/modsecurity2/ folder. Any ideas?

Thanks!

Code:

<IfModule security2_module>
   
   SecRuleEngine On
   SecDefaultAction log,auditlog,deny,status:403,phase:2,t:lowercase,t:replaceNulls,t:compressWhitespace
   
   SecAuditEngine RelevantOnly
   SecAuditLogType Serial
   SecAuditLog logs/mod_security2.log
   
   
   ## -- General rules --------------------
   
   SecRule ARGS "c:/" t:normalisePathWin
   SecRule ARGS "\.\./" t:normalisePathWin
   SecRule ARGS "d:/" t:normalisePathWin
   
   ## -- phpBB attack --------------------
   SecRule ARGS:highlight "(\x27|%27|\x2527|%2527)"

   # Load Core ModSecurity Rules
   Include conf/modsecurity2/*.conf
</IfModule>

Give us a few lines from your logs, so we see whats going on ?

To use the complete core mod_security rules makes mostly no sense. special the rules for application you not use. It's overhead and can give false positives.

Best is, pick only the genral rules and rules specific for the applications you are running. For example when you do not use SQL then it makes no sense to use SQL rules.

It's a minor issue, but the issue is that the mod_security2.log is empty and the errors are written to the error.log even though the following line is included:
Code:

SecAuditLog logs/mod_security2.log

Sorry, I am new to Apache.[/code]
