Security Basics: Any host based and application based log analysis tools around

["ricci" <ricci () cs ust hk>]

Hello All,

        Do you aware of any host based and application based log analysis tools
around? I'm looking for some web log, syslog and Windows Event Log, and
application logs including SAP, Oracle Finance, Siebel and PeopleSoft log
analysis tools.

        Are you aware of any tools, so I can use that for log analysis or even
intrusion detection purpose.

        THanks.
