I was just wanting to follow up. Is anyone able to confirm the proper logging settings when using ModSecurity, and sending the logs out via mlogc to AuditConsole? Should we have our modsecurity_crs_10_setup.conf SecDefaultAction lines set to the following?
SecDefaultAction "phase:1,pass,nolog" SecDefaultAction "phase:2,pass,nolog" Thanks!

I am confused on how it should be set as well when sending logs to AuditConsole using mlogc. Here is a summary of relevant settings I have right now (below). I guess it seems as though the logging settings are not able to combine one correlated event into the audit log. They can only combine one correlated event into the apache error_log? ############ modsecurity_crs_10_setup.conf Settings ########################## # Collaborative Detection Mode SecDefaultAction "phase:1,pass,nolog" SecDefaultAction "phase:2,pass,nolog" # Collaborative Detection Blocking # SecAction \ "id:'900004', \ phase:1, \ t:none, \ setvar:tx.anomaly_score_blocking=on, \ nolog, \ pass" ############ modsec2.user.conf Settings ###################################### SecDataDir /usr/local/apache/conf/sec-data SecTmpDir /usr/local/apache/conf/sec-tmp SecRuleEngine On SecPcreMatchLimit 50000 SecPcreMatchLimitRecursion 50000 # With SecRequestBodyAccess turned on care needs to be taken with false positives SecRequestBodyAccess On SecRequestBodyLimit 134217728 SecRequestBodyLimitAction ProcessPartial SecRequestBodyNoFilesLimit 131072 SecRequestBodyInMemoryLimit 131072 SecResponseBodyAccess On SecResponseBodyMimeType (null) text/html text/plain text/xml SecResponseBodyLimit 524228 SecResponseBodyLimitAction ProcessPartial SecServerSignature Apache SecCookieFormat 0 # Additional ModSecurity Logging Options for mlogc # Use ReleventOnly auditing SecAuditEngine RelevantOnly SecAuditLogRelevantStatus "^(?:5|4(?!04))" # Must use concurrent logging SecAuditLogType Concurrent # Send all audit log parts SecAuditLogParts ABDEFHIJKZ # Use the same /CollectorRoot/LogStorageDir as in mlogc.conf SecAuditLogStorageDir /var/log/mlogc/data # Pipe audit log to mlogc with your configuration SecAuditLog "|/usr/local/modsecurity/bin/mlogc /etc/mlogc.conf" # OWASP Rules Include conf/owasp-modsecurity-crs/modsecurity_crs_10_setup.conf Include conf/owasp-modsecurity-crs/activated_rules/*.conf # Trustwave Commercial Rules Include conf/slr_vuln_rules/owasp_crs_integration/attack_type/*.conf Wesley Render, IT Consultant, RHCSA Phone: 1.403.228.1221 ext 201 www.otherdata.com -----Original Message----- From: owasp-modsecurity-core-rule-set-boun...@lists.owasp.org [mailto:owasp-modsecurity-core-rule-set-boun...@lists.owasp.org] On Behalf Of Earl Fogel Sent: August-20-14 9:59 AM To: OWASP Mod Security Subject: Re: [Owasp-modsecurity-core-rule-set] inbound_anomaly_score_level - Only send critical events I have this problem as well.
