Re: Snort 2.8.3 SID rule value upper bound?

["Geoff Whittington" <geoff.whittington () gmail com>]

First, thank-you for your replies - I've been away from the office

We encountered an event when a signature required a large number of
rules and it broke our typical <10 rule assumption. In a perfect world
a doubling would help us. We ended working around the issue, however.

Best wishes,
 - Geoff
