  1. WinLogcheck Ported to Windows by JP Vossen PANTUG 9/12/2001 Minor (URL) updates 5/17/2007

  2. What is Logcheck? • A UNIX tool written by Craig H. Rowland crowland@psionic.com (http://www.psionic.com/abacus/logcheck --> http://sourceforge.net/projects/sentrytools/) • Uses standard UNIX tools to search UNIX log files for “interesting” events

  3. What is WinLogcheck? • A port of the UNIX logcheck tool to Windows (NT/2000/XP?) by Me • Uses a batch file “wrapper” and native Win32 ports of various standard UNIX tools, and other utilities • cat, date, egrep, rm, sed, sh • DumpEvt, blat, auditpol

  4. How Does It Work? • Wrapper.cmd • Sets some environment variables • Uses DumpEvt to dump the Event Logs into text (it picks up where it left off last time) • Runs sh (the UNIX Bourne Shell) to run logcheck.sh

  5. How Does it Work? • Logcheck.sh • Read and sets some environment variables • “Greps” logcheck.hacking for blatant hacking attempts • Greps logcheck.violations and reverse greps logcheck.violations.ignore for for security violations • Reverse greps logcheck.ignore and reports everything else not in the ignore file

  6. What Happens When it Runs? • Install (Setup.bat) • Configuration, install and enable logging • Run the First Time • Processes your entire Event Logs! • You’ll get a gigantic message! • Run After That • Periodically (once per hour, twice per day, etc.) • Much smaller and more useful messages

  7. Keyword Files • logcheck.hacking • login.*: .*LOGIN FAILURE.* FROM .*root • logcheck.violations • LOGIN FAILURE • The Event log service was started. • logcheck.violations.ignore • stat=Deferred • logcheck.ignore • sendmail.*User Unknown • WINS HAS INITIALIZED PROPERLY AND IS NOW FULLY OPERATIONAL

  8. Other Issues • It is useful or effective? • Surprisingly, given the simple approach, it actually works very well! • Is it scalable? • That depends on your logging, the number of machines, and the keyword file tuning • See the documentation • Readmes and FAQs

  9. What Else Needs to be Done? • I need PANTUG’s help with tuning the keyword files!! • I need to run these scripts in production environments to make sure everything works well (beta test) • It should not interfere with the machine – Blat adds a registry key and sends e-mail, DumpEvt interacts with Event Logs – no other OS/System interaction • Add a “noemail” option?

  10. Where can I get WinLogcheck? • WinLogCheck • http://www.jpsdomain.org/windows/winlogcheck.html • Upstream Source • http://www.psionic.com/abacus/logcheck
