need help, No entries found in /usr/local/apache/logs/modsec_audit.log

[sean2045]

Hi guys,

I followed this info to configure mod security

Configuring cPanel ModSecurity with Atomic ModSecurity Rules | UKHost4u Blog

However, after a few hours, I didn't get any log entries, I double checked everything, I couldn't find what was the problem.

does anyone know how to fix it?

Thank you

Sean

Hi, sean2045

Please provide me what you have configured in
/usr/local/apache/conf/modsec2.user.conf

Thanks

[cPanelTristan]

Can you also please check the following log for entries:

tail -500 /usr/local/apache/logs/modsec_debug_log

If mod_security isn't working, you'll probably see errors in that log file.

Did you test if is running?

[HTML]
apachectl -t -D DUMP_MODULES
[/HTML]

...and check if "security2_module" is on the list. After if is loaded test in browser with a directive and check logs.

it has this security2_module (shared), so it's running? what else is wrong?

modsecparse.pl is disabled.

Do you have those lines:

SecAuditEngine RelevantOnly
SecAuditLog logs/modsec_audit.log
SecDebugLog logs/modsec_debug_log

in modsec2.conf ?

Your configuration seems to be fine

go to this directory

/var/asl/data/audit

do you see any thing loged and also being updated?

also use
tail -f /usr/local/apache/logs/modsec_audit.log

do you see any updates to that file?

the last thing also is that have you restart the Apache after installing the Rule Sets

there are nothing in /var/asl/data/audit and /usr/local/apache/logs/modsec_audit.log, i restarted apache and reboot my server, it still nothing shows on any those logs.

looks like mod_security is running, what could be wrong?

[sean2045]

I have a question, since the audit log path is this /usr/local/apache/logs/modsec_audit.log

so where can i find what define this path /usr/local/apache/logs/modsec_audit.log?

after I recheck the configuration Configuring cPanel ModSecurity with Atomic ModSecurity Rules | UKHost4u Blog

Only this last part /usr/local/apache/conf/modsec2.user.conf, add those

SecPcreMatchLimit 50000
SecPcreMatchLimitRecursion 50000
SecRequestBodyAccess On
SecResponseBodyAccess On
SecResponseBodyMimeType (null) text/html text/plain text/xml
SecResponseBodyLimit 220621440

SecResponseBodyLimitAction ProcessPartial
# ConfigServer ModSecurity whitelist file
Include /usr/local/apache/conf/modsec2.whitelist.conf
# ASL/GOTROOT Rules
Include /usr/local/apache/conf/modsec_rules/*asl*.conf

to connect the rules to mod_security.

[sean2045]

After I submitted a ticket, the problem was solved,

so for anyone who has the the problems

in in modsec2.conf

LoadFile /opt/xml2/lib/libxml2.so
# LoadFile /opt/lua/lib/liblua.so
LoadModule security2_module modules/mod_security2.so
<IfModule mod_security2.c>
SecRuleEngine On
# See ModSecurity: Open Source Web Application Firewall
# "Add the rules that will do exactly the same as the directives"
# SecFilterCheckURLEncoding On
# SecFilterForceByteRange 0 255
SecAuditEngine RelevantOnly
SecAuditLog logs/modsec_audit.log
SecDebugLog logs/modsec_debug_log
SecDebugLogLevel 0
SecDefaultAction "phase:2,deny,log,status:406"
SecRule REMOTE_ADDR "^127.0.0.1$" nolog,allow
Include "/usr/local/apache/conf/modsec2.user.conf"
</IfModule>

change SecAuditEngine RelevantOnly to SecAuditEngine On


Sean

[borgia]

I am not using "SecAuditEngine On" and everything "RelevantOnly" is logged. The problem with you is that you didn't have events "RelevantOnly" to be logged at that time.
