Re: FTP passive data transfer FP's and flowbits

[Martin Holste <mcholste () gmail com>]

I've never found the alerts generated by the FTP preproc to be helpful
for anything other than a heartbeat to prove Snort is up and sniffing
traffic.  I recently started to suppress all from that gen_id.  I'm
strongly considering doing the same for the SSL preproc.  The amount
of resources it takes to investigate each false positive is not worth
the off-chance that you will be the one to discover a
never-before-seen new FTP/telnet hack.

Gaining the trust of online customers is vital for the success of any company
that requires sensitive data to be transmitted over the Web.   Learn how to 
best implement a security strategy that keeps consumers' information secure 
and instills the confidence they need to proceed with transactions.
