apache mod_security logs F12
A new rpm for mode_security F12 simplified the rules to get it started.
In the conf files the logs directive say to specify the path to the dir and make sure it exits.
As this dir list shows ther are several.
The suggested top dir is /var/log/msa
# cd /var/log/msa
[root@Jovette-14 msa]# ls -laZ
drw-------. apache apache system_u:object_r:var_log_t:s0 .
drwxr-xr-x. root root system_u:object_r:var_log_t:s0 ..
drwxr-x---. apache apache system_u:object_r:var_log_t:s0 SecAuditLog
drwxr-x---. apache apache system_u:object_r:var_log_t:s0 SecAuditLogStorageDir
drwxr-x---. apache apache system_u:object_r:var_log_t:s0 SecDataDir
drwxr-x---. apache apache unconfined_u:object_r:var_log_t:s0 SecDebugLog
drwxr-x---. apache apache system_u:object_r:var_log_t:s0 SecTmpDir
drwxr-x---. apache apache system_u:object_r:var_log_t:s0 SecUploadDir
After starting httpd and doing some web pages only the SecAuditLog and SecDebugLog had a log file and data.
from the next list all looks good but as the previous list shows, selinux needs some work.
# ls -l
total 24
drwxr-x---. 2 apache apache 4096 2009-11-07 07:24 SecAuditLog
drwxr-x---. 2 apache apache 4096 2009-10-26 05:28 SecAuditLogStorageDir
drwxr-x---. 2 apache apache 4096 2009-10-26 05:28 SecDataDir
drwxr-x---. 2 apache apache 4096 2009-11-07 07:36 SecDebugLog
drwxr-x---. 2 apache apache 4096 2009-10-26 05:28 SecTmpDir
drwxr-x---. 2 apache apache 4096 2009-10-26 05:28 SecUploadDir
to create the Dir's I used root and then
cd /var/log/msa
chown -R apache:apache SecAuditLog (for each dir name)
chmod 750 SecAuditLog (for each dir name)
These two are mutually exclusive (one or the other is used) but I created both to toggle the conf.
SecDataDir SecAuditLogStorageDir
SecTempDir is defaulted to /tmp - I put it in msa to track it better.
SecUploadDir - this may need to move
The next list shows the two logs that were created.
# ls -laZ
drwxr-x---. apache apache system_u:object_r:var_log_t:s0 .
drw-------. apache apache system_u:object_r:var_log_t:s0 ..
-rw-r-----. root root unconfined_u:object_r:httpd_log_t:s0 SecAuditLog.log
[root@Jovette-14 SecAuditLog]# ls -l
total 56
-rw-r-----. 1 root root 56203 2009-11-07 07:50 SecAuditLog.log
[root@Jovette-14 SecAuditLog]# cd ../SecDebugLog
[root@Jovette-14 SecDebugLog]# ls -laZ
drwxr-x---. apache apache unconfined_u:object_r:var_log_t:s0 .
drw-------. apache apache system_u:object_r:var_log_t:s0 ..
-rw-r-----. root root unconfined_u:object_r:httpd_log_t:s0 SecDebugLog.log
[root@Jovette-14 SecDebugLog]# ls -l
total 4
-rw-r-----. 1 root root 1484 2009-11-07 07:37 SecDebugLog.log
The next list is the end of the modsecurity_crs_10_config.conf file to set log files.
This shows debug and temp.
The point here is, YES, the "path/to/logdir" may include the log file name "path/to/logdir/logfile.log"
But you only create the dir, not the log as apache will create the log.
(And as it does, the selinux must be correct.)
But temp (non-log) is just a dir/path
# Whether to send ModSecurity messages to a separate debug log.
#
# Debug messages are very useful for, well, debugging. The default
# setting here copies (they always appear in the Apache error log)
# only the most important messages (errors and warnings).
#
# NOTE Debug logging is generally very slow. You should never
# use values greater than "3" in production.
#
SecDebugLog /var/log/msa/SecDebugLog/SecDebugLog.log
SecDebugLogLevel 3
# Configures the directory where temporary files will be created.
SecTmpDir /var/log/msa/SecTmpDir/SecTmpDir
Finally the httpd is started and the memory requirements has also increased, along with the child processes.

Now the questions are how to put into log rotate and what program to to use to processs the log information.
