best way to match on CIFS filenames?

I'm trying to write a rule to capture uploads of certain filenames via CIFS. However, over the years SMB became CIFS, Unicode was introduced, etc, etc. Which leads to the current mess whereby my "rule" is turning into "rules" as I try to figure out all the combinations. Anyway, I was wondering if there was any built-in 'normalizing' function I could use so that I could look for strings without worrying about their case or unicode status. e.g. a filename of "ntldr.exe" can be "NTLDR.EXE", "Ntldr.exE" as well as "n|00|T|00|l|00|D|00|r|00|.|00|e|00|x|00|e". I am making so many fat-finger mistakes getting that right that I'm hoping the Sourcefire guys have too ;-) -- Cheers Jason Haar Information Security Manager, Trimble Navigation Ltd.
