| Ascertaining the source of an event is important during forensic analysis. The correct determination of the event and what client requested the resource is important in relation to other events that happened at that same time.
Without sufficient information establishing the source of an event, investigation into the cause of event is severely hindered. Log record content that may be necessary to satisfy the requirement of this control includes, but is not limited to, time stamps, source and destination IP addresses, user/process identifiers, event descriptions, application-specific events, success/fail indications, file names involved, access control, or flow control rules invoked.
When configured for httplog, HAProxy logs uses the Common Log Format (CLF). The CLF format, a World Wide Web Consortium standard, captures the client IP address that requested the web server event in addition to other useful information. This will enable forensic analysis of server events in case of a malicious event. |
