RE: Scripting rule creation from PIixrules - 3.Nov.2005 11:46:00 AM
I looked into doing this kind of a script for a client once, but, for publishing rules especially, there's not a clean mapping of PIX rules and options to ISA rules and options (or at least clean enough that I could write a script to do it, someone else might have though). The end result for the client was that every rule would have to be examined/validated by hand anyway, so it was better to create them by hand correctly in the first place.
You can find scripts for importing subnets/IPs/domains/etc. into ISA objects from text files, though, at www.ISAscripts.org and www.ISAtools.org, so these might help you to do some of the work.
If you find a company that sells a tool to translate from PIX to ISA, please post it here!
